Early Childhood Infections

Children are subject to a variety of infectious diseases early in their lives, which have the potential to cause significant illness and mortality. It is not until the age of 7-8 years old that children have a fully mature immune system therefore, it is important to support your child’s immune system during this time. There is some exchange of antibodies between the mother and fetus during pregnancy, and further supplement from the mother via breast feeding. However, there are still some infections that pose significant risk to the developing child therefore an extensive vaccination schedule is required. Vaccination is essential in early childhood, and probably represents the most effective health intervention the world has ever seen at reducing morbidity and mortality. Depending on which country you live in, the schedule for childhood vaccination will vary.

Although, vaccination may prevent many harmful bacterial and viral infections, there are still some other infections that can cause considerable illness in childhood. Most childhood infections present with skin rashes or coughs and colds. All infections produce negative effects and outcomes on the child, consuming energy and interrupting development. Persistent infections causing significant malnutrition may result in failure to thrive, a condition of inadequate nutrition and weight below an acceptable level. More serious infections threatening breathing can develop, such as those causing pneumonia which represents a severe threat most likely requiring hospitalization.
