Can this lead to an HIV infection?
Hello, doctor: Recently, I was busy with some matters and left my thermos in a public place.
After I finished, when I went to retrieve it and later drank the water from the thermos, I suspected I smelled semen, and the water had a slightly sticky texture, which I accidentally ingested! I have seen news reports about men ejaculating into others' water bottles, so I am worried that I might have encountered the same situation.
If, hypothetically, there was semen from an unknown person in my thermos, and that person had HIV, would I be at risk of contracting HIV since I ingested their semen along with the water? I drank the water about two hours after retrieving the thermos, and the water was relatively cool.
The day before the incident, I also experienced bleeding gums from brushing too hard, which left me with an open wound.
I have heard that the HIV virus can survive in a closed environment like a thermos! Please help me with this concern!

More Info
The concern about HIV transmission through drinking water contaminated with semen is understandable, especially given the stigma and fear surrounding HIV/AIDS. However, it is important to clarify the scientific facts regarding HIV transmission and the viability of the virus in different environments.
HIV (Human Immunodeficiency Virus) is primarily transmitted through three main routes: sexual contact, blood exposure, and vertical transmission from mother to child. The virus is not transmitted through casual contact or through environmental surfaces, including water.
1. HIV Viability in Water: HIV does not survive well outside the human body. When exposed to air, the virus becomes inactive very quickly. In water, especially in a diluted form, the likelihood of HIV remaining viable is extremely low. Factors such as temperature, pH, and the presence of other substances can further reduce the virus's lifespan. In your scenario, if semen were to be introduced into a water bottle, the virus would likely not survive for long, especially after two hours, as you mentioned.
2. Semen and HIV: While semen can contain HIV, the concentration of the virus decreases rapidly when it is exposed to the environment. If someone were to ejaculate into a water bottle, the amount of virus present would be significantly diluted by the water, making transmission through ingestion highly improbable.
3. Ingestion of Contaminated Water: Even if you had ingested water that had been contaminated with semen, the gastrointestinal tract is not a conducive environment for HIV transmission. The virus would be exposed to stomach acid and digestive enzymes, which would further inactivate it.
4. Open Wounds and Risk: You mentioned having a bleeding gum due to brushing too hard. While open wounds can increase the risk of HIV transmission if they come into direct contact with HIV-infected fluids, the scenario you described does not present a significant risk. The virus would need to enter the bloodstream directly, which is unlikely to occur through the ingestion of contaminated water.
5. Psychological Impact: It is important to address the psychological aspect of your concern. Anxiety about potential HIV exposure can be overwhelming. If you are feeling anxious about this incident, it may be beneficial to speak with a healthcare professional who can provide reassurance and, if necessary, conduct an HIV test. Testing is the only way to confirm your HIV status, and it is recommended to wait at least three months after potential exposure for accurate results.
In conclusion, while your concerns are valid, the likelihood of contracting HIV through drinking water that may have been contaminated with semen is exceedingly low. HIV does not survive well outside the human body, and the conditions you described do not support transmission. If you continue to feel anxious or uncertain, seeking professional guidance can help alleviate your concerns and provide you with the information you need to feel secure about your health.
