Our Division of Infectious Diseases is the major referral center for infectious disease in the Washington, D.C., area, helping thousands of patients each year, and actively promoting prevention through community outreach and education.

The Importance of Diagnosis, Treatment and Prevention

Infectious diseases include any disease or illness caused by germs, such as bacteria and viruses. While you can take steps to prevent disease and infection through proper hygiene and other practices, children are often at an increased risk for certain conditions while their immune systems are still developing and simply because of exposure - kids being kids.

Because diagnosis and care for an infectious disease can be complex, it is important for your child to see a pediatric specialist who can accurately diagnose and treat your child's condition. Children's comprehensive services include care for children with infectious diseases and epidemiological tracking that, for contagious conditions, helps limit the spread of infection and prevent further outbreaks:


Many of the division's physicians - dually board certified in pediatrics and pediatric infectious disease - are involved in both teaching and research in infectious disease and epidemiology at Children's National and at the George Washington University School of Medicine and Public Health in Washington, D.C. Several faculty members also participate in government committees to assist in the development of national infectious disease guidelines.
