Division of Infectious Disease & Tropical Pediatrics

The mission of the Division of Infectious Diseases and Tropical Pediatrics is to improve the health of children by promoting excellence in diagnosis, management and prevention of infectious diseases through clinical care, education, research, advocacy and training.

Our clinical service provides offers comprehensive inpatient and outpatient consultative services for children with proven or suspected infections. We assist in the development and interpretation of diagnostic evaluations and in the formulation of management plans, including recommendations for type and duration of antimicrobial therapy. We evaluate children who present with uncertain diagnoses, recurrent or persistent infections, or who are found to have complicated infections.

Clinical Services

Specialized Evaluations

Travel Clinic

  • Provides evaluation of children with infections acquired abroad
  • Services to Physicians
  • Consultations
  • Second opinions
  • Diagnostic and management plans for complicated cases


Research efforts of the Division of Infectious Diseases and Tropical Pediatrics occur within the University of Maryland Center for Vaccine Development (CVD), a world-renowned multi-disciplinary research center that focuses on development and implementation of vaccines to prevent infections of global significance. In addition, we study strategies to prevent infections that occur among children living in the United States, such as influenza and methicillin-resistant Staphylococcus aureus (MRSA).

  • Vaccine Testing and Evaluation Units (VTEU): As one of the nine NIAID-funded VTEU sites in the U.S., we conduct clinical trials of vaccines and therapeutics in adults and children. The VTEUs have played a key role in the NIH's effort to develop new and improved vaccines and therapies against infectious diseases for over 40 years.
  • University of Maryland, Baltimore Cooperative Center for Translational Research on Human Immunology and Biodefense (UMB-CCHI): Funded by NIAID to support translational research in human immunology, we perform in-depth studies to further our understanding of the protective immunological mechanisms that can be elicited in the GI microenvironment of humans.  Moreover, because the normal GI flora (microbiota) is certain to influence the host immune response, we are conducting pioneering studies on the interactions between the local intestinal microbiota and the host immune response in humans.
  • CVD-Mali: In collaboration with investigators in the Malian Ministry of Health, we conduct epidemiologic and intervention studies with a focus on vaccine-preventable infectious diseases in children.
  • Malaria project field sites (Bandiagara Malaria Project in Mali, West Africa and Blantyre Malaria Project in Malawi, Central Africa): These sites comprise multidisciplinary teams that study malaria molecular epidemiology, antimalarial drug resistance, malaria in pregnancy, and malaria-HIV interactions, and conduct candidate malaria vaccine trials.
  • CVD Pediatric Clinical Studies Group: We conduct pediatric vaccine trials in private practices and in the University of Maryland Pediatrics at the Harbor (PATH) clinic sponsored by NIH and industry.
  • The Global Enterics Multi-Center Study (GEMS): a study of the cause and sequelae of diarrhea among children younger than 5 years of age living in seven developing countries


  • NIH Vaccinology Training Grant: Each year we accept 1-2 pediatricians into our Pediatric Infectious Disease Fellowship Program. The Vaccinology Training Grant supports fellows who pursue research projects related to vaccine development, immunology, or clinical trials.
