HIV transmission through a bottle of water with semen in it


I drank from a full bottle of water, and believe that it had been unsealed and ejaculated into before being re-sealed. I don't recall if the re-seal was somewhat tight or looser. I have a cold with post-nasal drip and sore throat. Could HIV survive in the bottle, and if so under which curcumstances? I do not know how much time transpired between the ejaculation and my drinking the water. Thank you for your time and attention.


Hello there,

Thank you for your inquiry. From what we gather from the question, you were asking about whether consuming semen found in a water bottle poses a risk of HIV transmission.

In this instance, there is No Risk of HIV acquisition (transmission of HIV is not possible in the given scenario). This scenario is considered to be no risk because:

1) Any/all HIV positive bodily fluid that may have been in the bottle you speak of is exposed to the environment. The CDC exclaims that "HIV does not survive long outside the human body (such as on surfaces), and it cannot reproduce outside a human host. Further, any HIV outside of the body or drying HIV can have a rapid (90%-99%) reduction in HIV concentration (1)

2) Digestive enzymes in the mouth/stomach are highly acidic and may inactivate HIV (2). If you had received a partners semen in the mouth directly, there is a much higher risk of acquisition due to the direct transfer to the bloodstream from the mouth. Yet, because you may have consumed the seminal fluid through an indirect source, there is a much lower risk of HIV transmission.

Further, it is nearly impossible to attribute any/all of your physical symptoms to HIV without adequate testing and positive results.

Recommendation: No need for HIV test with the scenario provided, refer to a physician for other health related questions.

All the best, AIDS Vancouver Helpline/Online, Cody
