If a two year old child were found to have aids what would be the most likely cause of infection?

The most likely cause of HIV infection in a two-year-old child would be perinatal transmission, meaning the child acquired the infection from the mother during pregnancy, childbirth, or breastfeeding. During these times, the mother's HIV-infected blood, vaginal fluids, or breast milk can transmit the virus to the baby.

It is important to note that without proper medical care and antiretroviral therapy, the risk of perinatal transmission is significantly higher, but with proper prenatal care and interventions, including antiretroviral prophylaxis for both the mother and baby, the risk of transmission can be greatly reduced.
