The KwaZulu Natal study involved around 2,700 babies born between 2001 and 2005. Major efforts were made to encourage and support women in breastfeeding by sending counsellors to their homes twice a week. The success of the strategy surprised the researchers. The authors say exclusive breastfeeding "ordinarily protects the integrity of the intestinal mucosa, which thereby presents a more effective barrier to HIV".

Less commonly, contact with infected blood causes HIV transmission. This can occur in health care providers (HCPs) or others exposed to infectious bodily fluids.  Transmission is facilitated by breaks in the skin or direct contact with [[Mucosal memberan|mucosal tissues]], such as those found in the eyes, mouth, anus, or vagina. Early in the epidemic, blood transfusions were a significant source of HIV transmission.

Other less likely means of transmission exist, though are rare. There are no confirmed cases from contact with the saliva, sweat or tears of an infected person.
