About us

If your child has a recurring fever or illness, or you suspect a disease caused by infection – or if you have returned from a foreign country where your child may have been exposed to parasites, bacteria or a fungus, it’s important for your child to be examined. The specialists in the Division of Pediatric Infectious Diseases at Cohen Children’s provide consultation, diagnosis and treatment for all types of infectious diseases in children, adolescents and young adults.

What we treat

Diagnostic and therapeutic services are offered at the Pediatric Infectious Diseases Division for:

  • Suspected or proven infections – particularly those that are recurrent, severe or caused by an unusual germ
  • Prolonged or recurrent fever
  • Suspected or proven Lyme disease
  • Suspected or proven tuberculosis
  • Suspected or proven Kawasaki syndrome
  • Difficulties with immunizations or lack of response to immunizations
  • Immunizations to prevent RSV infection


At the Pediatric Infectious Diseases division, we provide many specialized services, including:

Pediatric Lyme Disease Center
In conjunction with the Division of Rheumatology, patients with suspected or proven Lyme disease or other tick-borne disease are evaluated and treated. Ticks removed from children or adults are identified in our laboratory to determine if the tick is a type that can carry the germ of Lyme disease. Deer ticks are further analyzed to determine the length of time they were attached to the patient. The duration of attachment provides information that helps determine the risk of Lyme disease in the patient. Research into the prevention, treatment and mechanism of Lyme disease is conducted within the division.

Home intravenous antibiotic therapy
The infectious diseases division supervises the care of children who require courses of intravenous antibiotic therapy that can be administered at home. These patients include children with bone or joint infections, Lyme disease and infections of the heart (endocarditis).

Travel medicine

Consultations are provided regarding appropriate immunizations and other preventive measures, such as medicines for malaria or diarrhea prior to foreign travel.

The Division also provides information and vaccinations for children traveling to foreign countries, as well as for those who have recently been adopted from foreign countries. For those requiring immunizations for overseas travel, please download and complete the International Travel Medical Questionnaire. Bring your completed questionnaire to your appointment so we can assess your child’s specific immunization and medication needs.
