How the Virus Replicates
HIV can infect multiple cells in the body, including brain cells, but its main target is the CD4 lymphocyte, also known as a T-cell or CD4 cell. When a CD4 cell is infected with HIV, the virus goes through multiple steps to reproduce itself and create many more virus particles.
Treatment: How Viral Replication Can be Inhibited
To reduce your risk of HIV infection, practice protected/safe sex. Don’t inject things through needles but if you do, use only sterile injection equipment and water. Never share equipment with others.
