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 Canadian children in the early 20th century, have declined by 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 incidence of infectious disease decreases as their immune systems mature. Furthermore, children who experience more infectious diseases at an early age in group out-of-home care have a decreasing incidence of infectious diseases as they grow older. In fact, they have fewer 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 adults who 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 may also be additional childcare costs or lost wages for parents/caregivers of children who must be excluded from group care.
- Overuse of antibiotics in an effort to get c
