A child is not necessarily infected when the mother has AIDS. There is a corresponding probability of transmission, statistically between 20% and 45%, which is the probability of the mother transmitting HIV to her child without any intervention. If the mother takes oral antiviral drugs, such as a combination of lamivudine, zidovudine and nevirapine, or other combinations, the child’s growth and development will not be affected and the probability of HIV transmission to the child will be significantly reduced. Corresponding studies have shown that the transmission rate can be reduced to less than 5%, and even lower figures are available. After delivery, it is not possible to breastfeed the child because HIV can be transmitted to the child through the breast milk. If the mother has AIDS, she must do the appropriate interruption measures, otherwise the probability of the child contracting AIDS is still relatively high.
