Introduction
Science and experience tell us that infectious disease, especially gastrointestinal disease, which means vomiting and diarrhea, and respiratory disease, including coughs, colds, sore throats, and runny noses, are increased among children who are cared for in out-of-home group settings. In addition, such children may be at increased risk for certain other infections that may be transmitted by insects or by body fluids. It's also true that children who are cared for in group out-of-home settings are more likely to experience infectious illnesses that are more severe and more prolonged (although 90% of those infections are mild and self-limited, requiring no special treatment).
But there's good news, too. Infectious illnesses such as pneumonia and influenza, which together were the leading causes of death among U.S. children in the early 20th century, have declined 99.7 percent. Common childhood illnesses such as diphtheria, whooping cough, measles, mumps, and rubella are rare except in communities where immunization rates are low, and polio is unheard of in our country today.
Although younger children are more susceptible to infectious illness because their immune systems are immature, as they grow older, the incidents of infectious disease decreases as their immune systems mature. Furthermore, children who experience more infectious disease at an early age in group out-of-home care have a decreasing incidence of infectious disease as they grow older. In fact, they have less infectious illnesses in kindergarten than children who were taken care of exclusively at home. Illness also decreases with years of attendance in out-of-home early care and education settings.
There are negative consequences of childhood illness, including:
It’s unpleasant to be sick (for children or the adults that may also become infected).
Illnesses that are minor in children can be much more serious for adults and pregnant women.
Some illnesses have severe effects (and can even be life-threatening).
There are short-term medical costs.
There may also be additional child care costs or lost wages for parents/caregivers of children that must be excluded from group care.
Overuse of antibiotics in an effort to get children well contributes to antibiotic resistance among common bacteria.
To prevent illness we need to understand the different ways illness is spread, how immunizations protect children, and what universal precautions early care and education program staff can take to prevent the spread of illness.
How Illnesses are Transmitted
Bacteria, viruses, fungi, and parasites that cause illness can be transmitted in five ways, including through:
the respiratory route
the fecal-oral route
the direct contact route
the bodily fluid route (including blood, urine, vomit, and saliva)
the vector-borne route
Respiratory Transmission
Most respiratory germs stay in the nose, sinuses, mouth and throat, or possibly the middle ear. Upper respiratory illnesses (colds) are the most common and the most likely to be transmitted in early care and education settings.
The more common respiratory illnesses include:
Sinusitis
Sore throat
Common cold
Recurrent middle ear infection
Strep throat
RSV
Pneumonia
Bronchitis
Pneumonia and bronchitis are rarely the result of an infection picked up in an early education setting. We also have immunizations for many respiratory diseases that are rarely transmitted in early care and education settings today, including:
Mumps
Measles
Bacterial meningitis
Chicken pox
Diphtheria
Pertussis
Pneumonia
Seasonal flu
If we could actually see what comes out of a child's mouth along with a cough or a sneeze, we might appreciate the respiratory route of infectious disease transmission more.
The germs that are in this contaminated cloud of exhalation can wind up on surfaces and hands and be transmitted to others. Staff and children who are able to are encouraged to cough into their sleeves. Covering your mouth with your hand only transfers these germs to your hand. This will be addressed more in depth later in the chapter.
Fecal-Oral Transmission
When organisms that live in our intestines get into our mouths they can cause illness. Usually, this happens via someone's hands, usually our own. Fecal-oral routes diseases include:
Hepatitis A
diarrhea
hand, foot, and mouth disease
pinworms
rotavirus
norovirus
giardia
shigella
cryptosporidiosis
That is why it is so important that everyone wash hands after using the bathroom, changing diapers, when preparing food, and before eating.
Food Poisoning
E. coli and salmonella are two of the germs that you may also have heard mentioned in the news when grocery stores send back fresh vegetables, meat, or poultry. These organisms originate with farm animals themselves and they can cause diarrhea and vomiting if children or staff eat contaminated food. Properly preparing and serving fresh produce, meat, and poultry is essential to prevent food poisoning.
Direct Contact Transmission
Direct contact with another person's skin (or hair) puts infants and children at risk of illnesses such as:
cold sores
conjunctivitis
pink eye
impetigo
lice
scabies
ringworm (a fungus, not a worm).
Bodily Fluid Transmission
Bodily fluids, including saliva, urine, vomit, and blood, can cause illness, such as:
Dental caries (by saliva)
Cytomegalovirus or CMV (by urine)
Hepatitis B (preventable by vaccine)
Hepatitis C (rare in children)
HIV (no cases of transmission in an early education setting)
Vector-Borne Transmission
A vector is a living thing that can transmit disease. We know, for example, that ticks can transmit Lyme disease and Rocky Mountain spotted fever. Fleas are known to transmit Bubonic plague and typhus. Mosquitoes can infect people with St. Louis encephalitis (SLE), dengue fever, Zika virus, and West Nile disease. Rats and mice can transmit leptospirosis, trichinosis, hantavirus, and bacterial food poisoning. Raccoons can spread raccoon roundworm.
While these illnesses are relatively uncommon, the risk reminds us of the importance of
utilizing integrated pest management techniques to keep insects and rodents out of buildings (covered later in this chapter)
using insect repellant specifically recommended for children during outdoor activities
removing standing water in which mosquitoes can lay their eggs
checking for and removing ticks (addressed in Figure 4.10) in centers when children come back in after playing in or near heavily wooded areas
356
Pandemic/COVID Resources
We don’t know when another global or regional health threat may occur so child care professionals should follow the best health practices of the time to keep children and staff healthy.
Where should you turn to for information on best practices during a pandemic? During a pandemic take guidance from the Center for Disease Control. This organization will provide over-all guidance procedures for preventing the spread of disease. The second organization to turn to is the Wisconsin Department of Children and Families (DCF). This organization will have information on procedures specific to regulated child care programs. The WI Department of Children and Families (DCF) will determine if there is a need to adjust child care regulations based on the current health threat
Precautions for the most recent pandemic Covid-19.
Individuals who are exposed to Covid-19 should follow CDC’s quarantine guidance based on their vaccine status and symptoms.
Child care programs that have a positive case, staff and/or child, are required to report the case to their local health department and licensing specialist.
Why is it important to understand how illnesses and diseases are spread?
Immunizations
Prevention of infectious disease starts with immunizations (or vaccines). Immunizations are considered the number one public health intervention of the 20th century and one of the top 10 interventions of the first decade of the 21st century.
357
On-time vaccination throughout childhood is essential because it helps provide immunity before children are exposed to potentially life-threatening diseases. Vaccines are tested to ensure that they are safe and effective for children to receive at the recommended ages.
358
See Figure 8.X for the current schedule of immunizations.
Fully vaccinated children in the U.S. are protected against sixteen potentially harmful diseases (see Figure 8.X). Vaccine-preventable diseases can be very serious, may require hospitalization, or even be deadly — especially in infants and young children.
359
Here is the schedule from the CDC to ensure a child is fully vaccinated:

How Vaccines Work
The immune system helps the human body fight germs by producing substances to combat them. Once it does, the immune system “remembers” the germ and can fight it again. Vaccines contain germs that have been killed or weakened. When given to a healthy person, the vaccine triggers the immune system to respond and thus build immunity.
Before vaccines, people became immune only by actually getting a disease and surviving it. Immunizations are an easier and less risky way to become immune.
Vaccines are the best defense we have against serious, preventable, and sometimes deadly contagious diseases. Vaccines are some of the safest medical products available, but like any other medical product, there may be risks. Accurate information about the value of vaccines as well as their possible side effects helps people to make informed decisions about vaccination.
Potential Side Effects
Vaccines, like all medical products, may cause side effects in some people. Most of these side effects are minor, such as redness or swelling at the injection site. Read further to learn about possible side effects of vaccines.
Any vaccine can cause side effects. For the most part, these are minor (for example, a sore arm or low-grade fever) and go away within a few days.
362
Serious side effects after vaccination, such as severe allergic reaction, are very rare.
363
Remember, vaccines are continually monitored for safety, and like any medication, vaccines can cause side effects. However, a decision not to immunize a child also involves risk and could put the child and others who come into contact with him or her at risk of contracting a potentially deadly disease.
How Well Do Vaccines Work?
Vaccines work really well. No medicine is perfect, of course, but most childhood vaccines produce immunity about 90–100% of the time.
What about the argument made by some people that vaccines don’t work that well and that diseases would be going away on their own because of better hygiene or sanitation, even if there were no vaccines?
That simply isn’t true. Certainly better hygiene and sanitation can help prevent the spread of disease, but the germs that cause disease will still be around, and as long as they are they will continue to make people sick.
All vaccines must be licensed (approved) by the Food and Drug Administration (FDA) before being used in the United States, and a vaccine must go through extensive testing to show that it works and that it is safe before the FDA will approve it. Among these tests are clinical trials, which compare groups of people who get a vaccine with groups of people who get a control. A vaccine is approved only if FDA makes the determination that it is safe and effective for its intended use.
If you look at the history of any vaccine-preventable disease, you will virtually always see that the number of cases of disease starts to drop when a vaccine is licensed. Vaccines are the most effective tool we have to prevent infectious diseases.
Opposition to Vaccines
In 2010, a pertussis (whooping cough) outbreak in California sickened 9,143 people and resulted in 10 infant deaths: the worst outbreak in 63 years (Centers for Disease Control 2011b). Researchers, suspecting that the primary cause of the outbreak was the waning strength of pertussis vaccines in older children, recommended a booster vaccination for 11–12-year-olds and also for pregnant women (Zacharyczuk 2011). Pertussis is most serious for babies; one in five needs to be hospitalized, and since they are too young for the vaccine themselves, it is crucial that people around them be immunized (Centers for Disease Control 2011b). Several states, including California, have been requiring the pertussis booster for older children in recent years with the hope of staving off another outbreak.
But what about people who do not want their children to have this vaccine, or any other? That question is at the heart of a debate that has been simmering for years. Vaccines are biological preparations that improve immunity against a certain disease. Vaccines have contributed to the eradication and weakening of numerous infectious diseases, including smallpox, polio, mumps, chickenpox, and meningitis.
However, many people express concern about the potential negative side effects of vaccines. These concerns range from fears about overloading the child’s immune system to controversial reports about devastating side effects of the vaccines.
365
Although children continue to get several vaccines up to their second birthday, these vaccines do not overload the immune system. Every day, an infant’s healthy immune system successfully fights off thousands of antigens – the parts of germs that cause their immune system to respond. Even if your child receives several vaccines in one day, vaccines contain only a tiny amount of antigens compared to the antigens your baby encounters every day.
This is the case even if your child receives combination vaccines. Combination vaccines take two or more vaccines that could be given individually and put them into one shot. Children get the same protection as they do from individual vaccines given separately—but with fewer shots.
366
One misapprehension is that the vaccine itself might cause the disease it is supposed to be immunizing against.
367
Vaccines help develop immunity by imitating an infection, but this “imitation” infection does not cause illness. Instead, it causes the immune system to develop the same response as it does to a real infection so the body can recognize and fight the vaccine-preventable disease in the future. Sometimes, after getting a vaccine, the imitation infection can cause minor symptoms, such as fever. Such minor symptoms are normal and should be expected as the body builds immunity.
368
Another commonly circulated concern is that vaccinations, specifically the MMR vaccine (MMR stands for measles, mumps, and rubella), are linked to autism. The autism connection has been particularly controversial. In 1998, a British physician named Andrew Wakefield published a study in Great Britain’s Lancet magazine that linked the MMR vaccine to autism. The report received a lot of media attention, resulting in British immunization rates decreasing from 91 percent in 1997 to almost 80 percent by 2003, accompanied by a subsequent rise in measles cases (Devlin 2008). A prolonged investigation by the British Medical Journal proved that not only was the link in the study nonexistent, but that Dr. Wakefield had falsified data in order to support his claims (CNN 2011). Dr. Wakefield was discredited and stripped of his license, but the doubt still lingers in many parents’ minds.
In the United States, many parents still believe in the now-discredited MMR-autism link and refuse to vaccinate their children. Other parents choose not to vaccinate for various reasons like religious or health beliefs. In one instance, a boy whose parents opted not to vaccinate returned home to the U.S. after a trip abroad; no one yet knew he was infected with measles. The boy exposed 839 people to the disease and caused 11 additional cases of measles, all in other unvaccinated children, including one infant who had to be hospitalized.
According to a study published in Pediatrics (2010), the outbreak cost the public sector $10,376 per diagnosed case. The study further showed that the intentional non-vaccination of those infected occurred in students from private schools, public charter schools, and public schools in upper-socioeconomic areas (Sugerman et al. 2010).

Note
What about the Flu Vaccine?
There are many reasons to get an influenza (flu) vaccine each year. Below is a summary of the benefits of flu vaccination, and selected scientific studies that support these benefits.
Flu vaccination can keep you from getting sick with flu.
Flu vaccination can reduce the risk of flu-associated hospitalization.
Flu vaccination is an important preventive tool for people with chronic health conditions.
Flu vaccination helps protect women during and after pregnancy and helps protect the baby from flu for several months after birth.
Flu vaccination can be life-saving in children.
Flu vaccination has been shown in several studies to reduce the severity of illness in people who get vaccinated but still get sick.
Getting vaccinated yourself may also protect people around you, including those who are more vulnerable to serious flu illness, like babies and young children, older people, and people with certain chronic health conditions.
371
Pause to Reflect
Using the information that has been provided about immunizations, think of ways you could respond to the following:
“I don’t believe in giving all of the vaccines, like chicken pox. It’s better for children to just get the disease like we all did when we were kids.”
“Why do they have to give vaccines so early? It seems like it’s too much, too quickly.”
“I have heard that vaccines give some kids autism. And even if they don’t, the side effects are just too scary.”
Universal Precautions to Prevent the Spread of Illness
There are some standard practices that prevent, or reduce the risk of, the spread of illness in early care and education programs. These are modeled after practices in health care, where everyone is treated as being potentially infected with something that is contagious. Many illnesses are actually contagious before the infected person is symptomatic, so waiting until you see signs of illness is an ineffective way of preventing its spread. Child care providers can practice these four things to help control the spread of illness.
Hand washing
Use of disposable nonporous gloves when working with bodily fluids
Disinfecting potentially contaminated surfaces
Proper disposal of potentially contaminated waste
373
Handwashing
Regular handwashing is an important step to minimizing the spread of germs. Hands pick up germs from all of the things they touch and then spread them from one place to another. Germs that are on hands can also enter the body when a person eats or when they touch their eyes, nose, mouth, or any area on the body where the skin is broken (because of a cut, rash, etc.).
All that is needed for handwashing is soap and clean, running water. Handwashing with soap and water removes visible dirt and hidden germs. Studies have demonstrated that handwashing reduced the number of diarrheal illnesses by 31 percent and respiratory illnesses by 21 percent.
Hands should be washed:
before eating, feeding, or preparing food. This prevents germs from getting into the mouth from hands. (Hygiene practices related specifically to food safety will be addressed in Chapter 15.)
after touching saliva (after feeding or eating), mucus (wiping a nose, using a tissue), bodily fluids (toileting, diapering), food, or animals
when visibly dirty, after touching garbage, or after cleaning
The Center for Disease Control recommends the following handwashing steps:
“Wet your hands with clean, running water (warm or cold) and apply soap.”
“Rub your hands together to make a lather and scrub your hands well; be sure to scrub the backs of your hands, between your fingers, and under your nails.”
“Continue rubbing your hands for at least 20 seconds. Need a timer? Hum the “Happy Birthday” song from beginning to end twice.”
“Rinse your hands well under running water.”
“Dry your hands using a clean towel or air dry them.”
Infants and young children will need help with handwashing.
Caring for Our Children
recommends that caregivers:
Safely cradle an infant in one arm to wash their hands at a sink.
Provide assistance with handwashing for young children that cannot yet wash their hands independently.
Offer a stepping stool to young children so they may safely reach the sink.
375
Wearing Disposable Gloves
Teachers and caregivers should wear gloves when they anticipate coming into contact with any of the following (on a child’s body or a contaminated surface)
Blood or bodily substances (i.e., fluids or solids)
Non-intact skin (e.g., rashes or cuts and scrapes)
376
Once the gloves are soiled, it’s important to remove them carefully.
Using a gloved hand, grasp the palm area of the other gloved hand and peel off the first glove.
Hold the removed glove in the gloved hand.
Slide fingers of the ungloved hand under the remaining glove at the wrist and peel off the second glove over the first glove.
Discard the gloves in a waste container.
377
After you remove your gloves you should wash your hands. “Do not reuse the gloves: this can spread germs from one child to another…Gloves provide added protection from communicable disease only if used correctly. If you use gloves incorrectly, you actually risk spreading more germs than if you don’t use gloves at all. Pay attention to your gloving technique so that you do not develop a false sense of security (and carelessness) when wearing gloves.”
379
Cleaning and Disinfecting
Washing Surfaces Germs spread onto surfaces from hands and objects (tissues or mouthed toys) or from a sneeze or cough. It is important to clean all surfaces well, including toys and any surface that a young child puts in his mouth, because germs cannot be seen and it is easy to overlook surfaces that do not look soiled or dirty.
Toileting and diapering involve germs from bodily fluids and fecal material. These germs spread easily in a bathroom onto hands, flushers, and faucets. Routinely washing bathroom surfaces removes most germs and prevents them from spreading. The kitchen is another area of the home where it is important to clean surfaces well.
The terms “cleaning,” “sanitizing,” and “disinfecting” deserve close attention.
Cleaning
removes visible soil, dirt, and germs. Soap and water will clean most surfaces.
Sanitizing
reduces, but does not totally get rid of, germs to a level that is unlikely to cause disease. Sanitizers may be appropriate to use on surfaces where you eat (such as a table or high chair tray) and with toys that children place in their mouths. It is important to follow the instructions on the label, which may also include rinsing surfaces after using the sanitizing product.
Disinfecting
destroys or inactivates infectious germs on surfaces. Disinfectants may be used on diaper-changing tables, toilets, and counter tops.
380
Early care and education programs can create a bleach and water solution of one tablespoon household bleach to one quart water for surfaces that need to be sanitized or disinfected. To use effectively, the surface must be wetted with the solution and allowed to air dry. A fresh bleach solution should be made each day to maintain effectiveness, and stored in a clearly labeled spray bottle out of children’s reach. Research shows that other chemicals (e.g., ammonia, vinegar, baking soda, Borax) are not effective against some bacteria.
381
“Items that can be washed in a dishwasher or hot cycle of a washing machine do not have to be disinfected because these machines use water that is hot enough for a long enough period of time to kill most germs.”
382
Cleaning and disinfecting are essential. Studies have shown that some germs, including influenza virus, can survive on surfaces for two to eight hours; rotavirus can survive up to 10 days.

Disposal of Waste
Proper disposal and storage of garbage waste prevent the spread of disease, odors, and problems with pests. Disposable items (diapers, gloves, paper towels, and facial tissues) should be thrown away immediately in an appropriate container. Make sure the container is water and rodent-proof, operated with a foot pedal, is lined with a plastic bag, within reach of diaper changing area, handwashing sink, and food preparation areas, out-of-reach of and unable to be knocked over by infants and toddlers. The containers should be emptied, cleaned, and sanitized daily.
385
Diaper Changing
Diaper changing areas should be smooth and nonporous (such as a plastic-covered pad), have a raised edge to prevent children from falling, be near a sink, be out of reach from children, and away from food preparation areas.
386
The following diaper changing procedure should be posted in the changing area and followed to protect the health and safety of children and staff:
Step 1
: Before bringing the child to the diaper changing area, perform hand hygiene (including putting on gloves, if using) and bring supplies to the diaper changing area, and place a disposable liner on the changing area.
Step 2
: Carry/bring the child to the changing table/surface, keeping soiled clothing away from you and any surfaces you cannot easily clean and sanitize after the change. Always keep a hand on the child.
Step 3:
Remove the soiled diaper and clothing without contaminating any surface not already in contact with stool or urine. Put soiled diaper in covered waste container. Put any soiled clothing in a plastic bag that is securely closed to give to family.
Step 4
: Clean the child's diaper area with disposable wipes and place soiled wipes into a covered waste container.
Step 5:
Removed the disposable liner and gloves and place in waste container
Step 6
: Use facial tissue to apply any creams or ointments. Slide clean diaper under the child and fasten it and dress the child.
Step 6
: Wash the child's hands and return the child to a supervised area.
Step 7
: Clean and disinfect the diaper-changing surface and any equipment or supplies that were touched (and any other area child soiled before changed).
Step 8
: Perform hand hygiene and record the diaper change, diaper contents, and/or any problems.
Caregivers/teachers should never leave a child unattended on a table or countertop. A safety strap or harness should not be used on the diaper changing table/surface.
387
Note
If Using Potty Chairs
Due to being hard to clean and disinfect, potty chairs are not ideal in a child care environment. If they are used, they should be used in the bathroom only. After each use:
Empty contents immediately into the toilet
Rinse with water and dump water into the toilet
Wash with soap and water (with a paper towel) and empty soapy water into the toilet
Rinse again and empty into the toilet
Spray with bleach solution
Air dry
Wash and disinfect sink
Wash hands (child and adult)
388
Pause to Reflect
You are at a job interview to become a teacher in an infant room and the director asks you what you would do to prevent the spread of illness in your classroom. What might you want to mention?
Environmental Health
Sometimes the threat to health comes from the environment itself. Air quality, chemical hazards, drinking water, mold, and pest management are all topics early care and education providers should be aware of.
Outdoor Air Quality
Children are more susceptible to the effects of contaminated air because they breathe in more oxygen relative to their body weight than adults.
389
Therefore, they “can be exposed to a lot of pollution. Children should be kept inside when air quality is poor, or should at least be discouraged from intense outdoor activity. Educators and parents should be aware that nearby construction and traffic can increase pollution. Mowing school lawns should never occur during school hours since this can cause an allergy or asthma attack. Insecticides should never be sprayed while children are in care. Outdoor air can include odors, pollutants from vehicles, and fumes from stored trash, chemicals, and plumbing vents.”
390
Indoor Air Quality
There are so many sources of indoor air pollution in childcare facilities that the air is considered to be two to five times more polluted than outdoor air. Common sources of indoor air pollution include combustion sources such as oil, gas, kerosene, coal, wood, and tobacco products; building materials and furnishings as diverse as deteriorated, asbestos-containing insulation, wet or damp carpet, and cabinetry or furniture made of certain pressed wood products; products for household cleaning and maintenance, personal care, or hobbies; central heating and cooling systems and humidification devices; and outdoor sources such as radon, pesticides, and outdoor air pollution.

Environmental Tobacco Smoke & Dangers of E-Cigarettes
Scientists are still working to understand more fully the health effects and harmful doses of e-cigarette contents when they are heated and turned into an aerosol, both for active users who inhale from a device and for those who are exposed to the aerosol secondhand. Another risk to consider involves defective e-cigarette batteries that have been known to cause fires and explosions, some of which have resulted in serious injuries. Most of the explosions happened when the e-cigarette batteries were being charged.

Mold
Mold is a fungus that thrives indoors when excessive moisture or water accumulates indoors or when moisture problems remain undiscovered or un-addressed. There are molds that can grow on wood, paper, carpet, and foods. There is no practical way to eliminate all mold and mold spores in the indoor environment. The way to control indoor mold growth is to control moisture.
Mold needs to be controlled in childcare settings to avoid possible health impacts for infants and children, including allergic reactions, asthma, and other respiratory issues.
396
Integrated Pest Management
Exposure to pests such as cockroaches, rodents, ants, and stinging insects in childcare centers may place children at risk for disease, asthma attacks, bites, and stings. Improper use of pesticides can also place children at risk. A recent study of pesticide use in child care centers revealed that 75% of centers reported at least one pesticide application in the last year. Several factors increase both children's exposures and their vulnerability to these exposures compared to adults. Children spend more time on the floor, where residues can transfer to skin and be absorbed.
Young children also frequently place their hands and objects in their mouths, resulting in the non-dietary ingestion of pesticides. Children are less developed immunologically, physiologically, and neurologically, and therefore may be more susceptible to the adverse effects of chemicals and toxins. There is increasing evidence of adverse effects of pesticides on young children, particularly on neurodevelopment.
397
Integrated Pest Management (IPM) is an effective and environmentally sensitive approach to pest management that relies on a combination of common-sense practices. IPM programs use current, comprehensive information on the life cycles of pests and their interaction with the environment.
Integrated Pest Management “(IPM) is a safer, more effective, longer-lasting method of pest control that emphasizes pest prevention by eliminating pests' access to food, water, and shelter. When using IPM, properly identify the pest and know why it's there so an appropriate combination of different pest control methods can be used for better effectiveness in controlling the pest.”

This information, in combination with the last toxic available pest control methods, is used to manage pest damage by the most economical means, and with the least possible hazard to people, property, and the environment.

Chemical Hazards
A child born today will grow up exposed to more chemicals than a child from any other generation in our nation's history. Of the 85,000 synthetic chemicals in commerce today, only a small fraction has been tested for toxicity on human health.
A 2005 study found 287 different chemicals in cord blood of 10 newborn babies - chemicals from pesticides, fast food packaging, coals, gasoline emissions, and trash incineration. Children are more vulnerable to toxic chemicals because their bodies are still growing and developing.
401
Plastics in Child Care Settings
Certain types of plastics contain chemicals such as phthalates, bisphenol A (BPA), polyvinyl chloride (PVC), and polystyrene that may be toxic to children. These plastics can be found in baby bottles, sippy cups, teething rings, pacifiers, and toys. When these items are in a child's mouth or when they are heated (such as in a microwave), children can be exposed to harmful chemicals that have the potential to mimic or suppress hormones and disrupt normal growth and development.
402
Drinking Water
The United States has one of the safest public drinking water supplies in the world. Over 286 million Americans get their tap water from a community water system. The US Environmental Protection Agency (EPA) regulates drinking water quality in public water systems and sets maximum concentration levels for water chemicals and pollutants.
Sources of drinking water are subject to contamination and require appropriate treatment to remove disease-causing contaminants. Contamination of drinking water supplies can occur in the source water as well as in the distribution system after water treatment has already occurred. There are many sources of water contamination, including naturally occurring chemicals and minerals (for example, arsenic, radon, uranium), local land use practices (fertilizers, pesticides, concentrated feeding operations), manufacturing processes, and sewer overflows or wastewater releases.
The presence of contaminants in water can lead to adverse health effects, including gastrointestinal illness, reproductive problems, and neurological disorders.
403
Young children are at particular risk for exposure to contaminants in drinking water because, pound for pound, they drink more water than adults (including water used to prepare formula), and because their immature body systems are less efficient at detoxification. Exposure to lead in drinking water is a serious health concern, especially for young children and infants since elevated lead levels in children may result in delays in physical or mental development, lower IQ, and even brain damage.
404
Under the federal regulations of the Safe Drinking Water Act, all water suppliers must notify consumers quickly when there is a serious problem with water quality. Water systems serving the same people year-round must provide annual consumer confidence reports on the source and quality of their tap water. National drinking water standards are legally enforceable, which means that both U.S. EPA and states can take enforcement actions against water systems not meeting safety standards.

Pause to Reflect
What are five important things that early care and education programs should remember about environmental health to keep children healthy?
Summary
Understanding how illness is spread, helps early care and education programs prevent the spread of illness. Immunizations also play an important role in preventing illness. And when program staff use universal precautions, including handwashing, cleaning and disinfecting, and proper disposal of waste, they also prevent the spread of illness.
Programs must also be aware of environmental hazards that present a threat to children’s health. These include both indoor and outdoor air quality, mold, and chemicals. Programs should use integrated pest management and make sure that their drinking water is safe as well.
Engaging Families
Teachers can use the following strategies to help families to develop their children’s health habits:
Provide families with concise, accurate information about ways to promote and develop good health habits in children; information should be presented in English and the families’ home languages. Capture their interest by addressing topics related to their children’s age and development, as well as topics related to common health risks for children, such as childhood obesity, asthma, and dental caries. Injury prevention and first-aid topics, such as treating burns, bleeding, and choking, are also relevant. Provide written informational materials that are brief and easy to read.
Provide individualized information, as well as general health information, to all families through daily contact, workshops, and parent meetings. All information should be presented in English and in the families’ home languages. Accommodate family schedules by providing workshops and meetings at various times (e.g., morning, afternoon, evening), and arrange for child care during meetings.
Show family members what the children are learning by sending home examples of work, encouraging families to visit the preschool and observe children in action, and sharing children’s portfolios during home visits. Reinforce children’s learning about health habits through take-home activities, lending libraries of read-aloud books in the languages of the families in the group, and displays of children’s work.
As you introduce health routines (e.g., handwashing, tooth brushing), invite family members to participate and model. Encourage families to contribute ideas or materials to interest areas that reflect diverse health habits at home.
Identify community resources related to health habits (e.g., handwashing, tooth brushing) and invite community personnel to participate in and bring resources to family workshops or parent meetings. Emphasize the role of home and family members in helping children to develop health habits, and inform all parents of the availability of free and low-cost community resources.
Be sensitive to and respectful of different values or beliefs, as well as varying levels of access to health products and services. Gather information on available and accessible resources in the community, including those for children with special needs, and provide this information to all families, translated into their home languages.
