From the Guidelines

No, you cannot get AIDS from an infected swimming pool. HIV, the virus that causes AIDS, does not survive well in water and cannot be transmitted through swimming pool water. The virus is primarily transmitted through specific bodily fluids like blood, semen, vaginal fluids, rectal fluids, and breast milk. It requires direct contact with these infected fluids to enter your bloodstream through cuts, sores, or mucous membranes. Chlorine and other chemicals used to treat swimming pools would quickly inactivate the virus even if it were present. Additionally, the large volume of water in pools would dilute the virus to non-infectious levels. HIV is a fragile virus that cannot survive long outside the human body and is not transmitted through casual contact like swimming, sharing towels, or toilet seats.

According to the guidelines for preventing opportunistic infections among HIV-infected persons 1, HIV-infected persons should avoid swimming in water that is likely to be contaminated with human or animal waste and should avoid swallowing water during swimming. However, this is to prevent waterborne infections such as cryptosporidiosis and giardiasis, not HIV transmission. The Centers for Disease Control and Prevention has never documented a case of HIV transmission through swimming in a pool, even when the pool was used by someone with HIV/AIDS.

Some key points to consider:

  • HIV is not transmitted through casual contact with contaminated water 1
  • Swimming pools are treated with chlorine and other chemicals that would inactivate the virus even if it were present 1
  • The large volume of water in pools would dilute the virus to non-infectious levels 1
  • HIV-infected persons should take precautions to avoid waterborne infections, but this is not related to HIV transmission 1

Overall, the risk of getting AIDS from an infected swimming pool is zero, as HIV is not transmitted through water. However, it is still important for HIV-infected persons to take precautions to avoid waterborne infections, such as avoiding swimming in contaminated water and avoiding swallowing water during swimming 1.

From the Research

HIV Transmission

  • HIV is a virus that attacks the body's immune system, and it is primarily spread through certain bodily fluids from a person who has a detectable viral load [(2,3,4)].
  • The virus can be transmitted through sexual contact, sharing needles, or from mother to child during pregnancy, childbirth, or breastfeeding [(2,3,4)].

Swimming Pool Transmission

  • There is no evidence to suggest that HIV can be transmitted through swimming pools 5.
  • However, people with HIV/AIDS may be at risk of exposure to waterborne pathogens, such as Cryptosporidium, when engaging in recreational water activities in contaminated surface waters 5.
  • It is essential for individuals with compromised immune systems, including those with HIV/AIDS, to take precautions when engaging in recreational water activities to minimize the risk of exposure to waterborne pathogens 5.

Prevention and Treatment

  • Post-exposure prophylaxis (PEP) and pre-exposure prophylaxis (PrEP) are effective tools for preventing HIV transmission [(2,3,4,6)].
  • PEP involves taking antiretroviral medication after potential exposure to HIV, while PrEP involves taking medication daily or on-demand to prevent HIV infection [(2,3,4,6)].
  • Early treatment and adherence to antiretroviral therapy can significantly reduce the risk of HIV transmission and improve health outcomes for individuals living with HIV [(2,3,4)].

Key Findings

  • Studies have shown that PEP and PrEP can be effective in preventing HIV transmission, but more research is needed to understand the best approaches for different populations and scenarios [(2,3,4,6)].
  • Individuals with HIV/AIDS should be aware of the potential risks associated with recreational water activities and take necessary precautions to minimize their exposure to waterborne pathogens 5.
