Through what does the HIV infection spread in the body?

HIV is a sexually transmitted infection (STI). The human immunodeficiency virus enters through the means of sexual organs and spreads to all parts of the body via lymph nodes. 

It can also be spread by contact with infected blood and from illicit injection drug use or sharing needles. 

It can also be spread from mother to child during pregnancy, childbirth or breastfeeding. 

Without medication, it may take years before HIV weakens your immune system to the point that you have AIDS.

One does not get HIV by consuming food handled by someone with HIV.
