text: The use of antiretroviral therapy (ART) during pregnancy in<unk> -infected women has resulted in a dramatic decrease in the transmission rate to<unk> , which is currently less than 2% in the United States, and the number of<unk>  with<unk>  in the United States continues to decline.  For<unk>  born to mothers with unknown<unk>  status, rapid<unk>  antibody testing of the mother and/or<unk> is recommended as soon as possible after birth, with immediate initiation of<unk> antiretroviral prophylaxis if the rapid test is positive. Virologic assays that directly detect<unk>  must be used to diagnose<unk><unk>  in<unk>  younger than 18 months.<unk>  antibody testing cannot establish<unk><unk>  in this age group because maternal<unk>  antibodies may persist and interfere with the interpretation of a positive<unk>  antibody test. Children living with<unk><unk>  bring new challenges of adherence, drug resistance, reproductive health planning, management of multiple drugs, and long-term complications from<unk>  and its treatments.
