Can You Contract AIDS from Used Tissue or Underwear? My Regrets Explained - Internal Medicine

Share to:

I regret it very much?


AIDS does not survive in the air and is not transmitted through casual contact.
Regarding your concern about using used tissues or underwear from a female, it is important to understand that HIV, the virus that causes AIDS, is primarily transmitted through specific bodily fluids such as blood, semen, vaginal fluids, and breast milk.

The risk of contracting HIV from using a used tissue or underwear is extremely low to nonexistent, especially if there are no visible bodily fluids present.
However, it is always advisable to practice safe hygiene and avoid any actions that could potentially expose you to infections.
If you have further concerns about your health or potential exposure to HIV, it would be best to consult a healthcare professional for personalized advice and testing if necessary.

Hello! Due to the inability to assess the following risk factors: 1.
Whether the owner of the toilet paper or underwear is an infected individual; 2.
How long the bloodstains or secretions on the toilet paper or underwear have been outside the body; 3.
Whether there are any wounds on the individual's genitalia, it is difficult to answer your question.
However, since this incident occurred a long time ago and you have already passed the window period, I recommend that you undergo an HIV antibody test to ensure your health.
Wishing you and your family peace and happiness.
Sincerely, Dr.
Cheng Shu-Hsing, Department of Internal Medicine, Taoyuan Hospital, Ministry of Health and Welfare.

The concern regarding the transmission of HIV (Human Immunodeficiency Virus) through contact with used tissues or underwear is understandable, especially given the stigma and fear surrounding the virus. To address your question directly: the risk of contracting HIV from used tissues or underwear is extremely low to virtually nonexistent.

HIV is a virus that is primarily transmitted through specific bodily fluids, including blood, semen, vaginal secretions, and breast milk. The Centers for Disease Control and Prevention (CDC) outlines three main routes of transmission: sexual contact, sharing needles, and from mother to child during childbirth or breastfeeding. Importantly, HIV is not transmitted through casual contact or through the air.
When it comes to the scenario you described—using a used tissue or underwear for masturbation—the risk of HIV transmission is negligible for several reasons:
1. Virus Viability: HIV is known to be a fragile virus. It cannot survive long outside the human body. Once exposed to air, the virus begins to die rapidly. Studies have shown that HIV can become inactive within seconds to minutes when exposed to air, depending on the environment and the amount of virus present. Therefore, any potential virus present on a used tissue would likely be non-viable by the time you came into contact with it.

2. Body Fluid Concentration: The concentration of HIV in vaginal secretions or menstrual blood is much lower than in blood. Even if there were traces of these fluids on a used tissue, the likelihood of sufficient viral load being present to cause infection is extremely low.

3. Masturbation Mechanics: The act of masturbation itself does not facilitate the entry of the virus into the bloodstream unless there are open wounds or significant abrasions on the skin. If your skin is intact, the risk remains minimal.

4. Psychological Impact: It’s common to feel regret or anxiety about past behaviors, especially when they involve sexual health. However, it is essential to focus on the present and take proactive steps to ensure your health moving forward. If you have concerns about your HIV status or other sexually transmitted infections (STIs), consider getting tested. Many clinics offer confidential testing and counseling.

5. Education and Awareness: Understanding how HIV is transmitted can help alleviate fears. Engaging in safe practices, such as using condoms during sexual activity and avoiding sharing needles, can significantly reduce the risk of transmission.

In conclusion, while your past actions may cause you concern, the likelihood of contracting HIV from used tissues or underwear is exceedingly low. It’s important to focus on safe practices moving forward and to seek testing if you have any doubts about your health. Remember, taking care of your mental and physical health is paramount, and seeking professional advice can provide clarity and peace of mind. If you have further questions or need support, don’t hesitate to reach out to a healthcare provider.
