One can only get
HIV by coming into direct contact with certain body fluids from a person with HIV who has a detectable viral load. These fluids are:
Blood
Semen (cum) and pre-seminal fluid
Rectal fluids
Vaginal fluids
Breast milk
For transmission to occur, the HIV in these fluids must get into the bloodstream of an HIV-negative person through a mucous membrane (found in the rectum, vagina, mouth, or tip of the penis); open cuts or sores; or by direct injection.
People with HIV who take HIV medicine daily as prescribed and get and keep an undetectable viral load have effectively no risk of sexually transmitting HIV to their HIV-negative partners.
Contact between broken skin, wounds, or mucous membranes and HIV-infected blood or blood-contaminated body fluids.
Deep, open-mouth kissing if both partners have sores or bleeding gums and blood from the HIV-positive partner gets into the bloodstream of the HIV-negative partner. HIV is not spread through saliva.
Eating food that has been pre-chewed by a person with HIV. The contamination occurs when infected blood from a caregiver’s mouth mixes with food while chewing. The only known cases are among infants
