  • Have a very low level of HIV in their blood.

A small number of people never become infected with HIV despite years of exposure to the virus. For example, they may have repeated, unprotected sex with an infected person. These people are said to be HIV-resistant. These people are never infected, so they can't spread HIV.

  • Some people's immune systems may be better able to destroy the virus.
  • Some strains of HIV may not be as harmful.
