The PAMA Branch supports and conducts both domestic and international research into the epidemiology, natural history, pathogenesis, transmission, treatment, and prevention of HIV infection and its complications in infants, children, adolescents, pregnant women, mothers, women of childbearing age, and the family unit as a whole. The Branch seeks to maximize cooperation with other NICHD components, other federal components and agencies, and interested private organizations that share a focus on maternal, adolescent, and pediatric HIV infection and disease, while avoiding overlap with other efforts.
