does saliva contain hiv
The saliva does not carry HIV that could be infectious or contagious. This is because; the saliva does not offer a very favorable condition for the sustenance of HIV. In fact, saliva is a good agent of destroying this virus. It carries special antibodies that fight the HIV components.
Even with the latest technology, HIV is not transmissible via sweat. And just to be thorough, not only sweat, but also nasal secretions, saliva, sputum, tears, urine, vomitus and feces are not implicated in the transmission of HIV, unless they contain visible blood!
