All pregnant people should get tested for HIV so they can take steps to stay healthy and protect their baby. Testing pregnant people for HIV and treating those who have HIV has decreased the number of babies born with HIV. HIV treatment is most effective when started as early as possible during a pregnancy. However, there are still great health benefits to beginning treatment even during labor or shortly after the baby is born. If a pregnant person gets HIV treatment early in their pregnancy, the risk of transmitting HIV to their baby is extremely low (1% or less). Pregnant people who test negative for HIV can talk to their health care provider about taking PrEP (pre-exposure prophylaxis) to prevent HIV.
