Transmission

The transfer (spread) of a disease or infection from person to person. HIV is spread mainly by having sex or sharing injection drug equipment such as needles with someone who has HIV. HIV can also be passed from mother to child during pregnancy, labor or delivery, or breastfeeding (through breast milk). HIV medicines reduce the risk of HIV transmission.
