HIV Myths
Insects
Mosquitoes, flies, ticks, fleas, bees or wasps do not transmit HIV. If a bloodsucking insect bites someone with HIV, the virus dies almost instantly in the insect's stomach as it digests the blood. HIV can live only in human cells.
Sharing Dishes or Food
HIV is not transmitted through casual contact, so it is impossible to get it through sharing a glass, fork, etc.
Donating Blood
Sterilized needles are always used in taking blood from donors in the United States.
Swimming Pools & Hot Tubs
The chemical used in swimming pools and hot tubs would instantly kill any HIV, if the hot water hadn't killed it already.
Pets
Humans are the only animals that can harbor HIV. An exception is chimpanzees used in research that have been intentionally infected with HIV. Their blood poses a threat to researchers working with them.
Other Contact
Contact with saliva, tears or sweat cannot transmit HIV. Using the same restroom as an HIV positive person will not cause transmission.
