Understanding HIV Transmission
Human immunodeficiency virus (HIV) is a virus that attacks and weakens the immune system over time. There are still many misconceptions about how HIV is and is not transmitted. Understanding the real risks can help prevent spreading myths and stigma around those living with HIV.
HIV Transmission Requires Fluid Exchange
For HIV transmission to occur, certain bodily fluids from an HIV positive person must come into direct contact with damaged tissue or the bloodstream of an HIV negative person. These fluids include:
- Blood
- Semen
- Vaginal fluids
- Rectal fluids
- Breast milk
Cells within these fluids carry high concentrations of the virus. Without this direct fluid exchange into the bloodstream, HIV cannot be transmitted.
Why Surface Contact Does Not Transmit HIV
Since the virus cannot survive long outside of the human body, simply rubbing or touching the skin, sweat, or saliva of someone with HIV will not result in transmission. The virus is unable to penetrate intact, healthy skin.
While open cuts or sores may allow entry into the bloodstream, rubbing or surface contact is still highly unlikely to transmit HIV. The amount of virus present would need to be extremely high, such as being exposed to a large open wound with visible blood from an HIV positive person. Even then, infection is improbable but not impossible.
Myths Surrounding HIV Transmission
There are many circulating myths about how HIV can and cannot be spread. Learning the facts is important to avoid accidental transmission and fight stigma.
Myth: HIV can be transmitted through saliva, sweat, or tears
Reality: Saliva, sweat and tears have either no or extremely low levels of HIV that cannot transmit the virus, even if ingested or in contact with cuts or open wounds. Dental exams, coughing, sneezing, sharing food or drinking glasses and casual kissing cannot transmit HIV.
Myth: HIV can be transmitted through toilet seats or swimming pools
Reality: HIV cannot survive long enough outside the body to pose a threat from toilet seats or pool water. Chlorine and other disinfectants in pools also prevent transmission.
Myth: Mosquitos or other insects can transmit HIV
Reality: HIV lives solely in humans. Insects do not carry or transmit the virus through bites.
The Reality of HIV Transmission
While media depictions may play into myths and fears surrounding HIV, the reality of transmission risks is straightforward:
- Sexual contact with exchange of bodily fluids
- Direct blood contact with high viral load fluids
- Sharing needles or syringes
- Pregnancy, birth or breastfeeding (vertical transmission)
Practicing safe sex via condoms, obtaining regularly tested blood products and never sharing needles or syringes can greatly reduce risks. Busting myths with facts and education is key to reducing fear, discrimination and accidental spread of HIV.
Living With HIV/AIDS
Thanks to modern antiretroviral therapies, those diagnosed with HIV today can enjoy long and healthy lifespans equivalent to the general population. When controlled with medication, the virus becomes undetectable and untransmittable.
Supporting those living with HIV helps destigmatize this manageable condition. Understanding exactly how HIV can and cannot spread gives everyone the power to make informed choices regarding their health and relationships.
