What is HIV?
HIV stands for human immunodeficiency virus. It harms your immune system by destroying the white blood cells that fight infection. This puts you at risk for serious infections and certain cancers. AIDS stands for acquired immunodeficiency syndrome. It is the final stage of infection with HIV.
Antiretroviral therapy (ART) is the use of HIV medicines to treat HIV infection. People on ART take a combination of HIV medicines (called an HIV treatment regimen) every day. ART is recommended for everyone who has HIV. ART can't cure HIV, but HIV medicines help people with HIV live longer, healthier lives
If you have an undetectable viral load, it means that there is less HIV in your body. Being undetectable means that the virus is less able to attack your immune system cells, which means that there will be less damage to your immune system. This allows people to stay healthier and and live longer.
Undetectable = Untransmittable. People who are undetectable do not transmit HIV to other people through sex. That is the meaning of “undetectable = untransmittable” or “U=U”, a message started by Prevention Access Campaign about what it means to be undetectable. If you have been taking HIV medications for at least six months, have a consistently suppressed viral load (less than 200 copies/mL), and continue taking your HIV medications as directed, you will not transmit HIV to others.
