Gonorrhea underwear


Hello, doctor.
I was treated for gonorrhea at the hospital last year.
I would like to ask if I washed my underwear in the washing machine with detergent and then air-dried them, will wearing those underwear again put me at risk for reinfection?

When it comes to preventing recurrent gonorrhea infections, the cleanliness of your underwear is certainly a factor, but it is not the only consideration. Gonorrhea, caused by the bacterium Neisseria gonorrhoeae, is primarily transmitted through sexual contact. Therefore, understanding how to manage your laundry and your sexual health is crucial.

Firstly, washing your underwear in a washing machine with detergent, followed by thorough drying, is generally effective in removing bacteria, including those that cause gonorrhea. The combination of detergent and heat from drying helps to eliminate pathogens. However, it is important to note that while washing can reduce the risk of bacteria surviving on fabric, it does not guarantee complete elimination of all pathogens, especially if the washing process is not done properly (e.g., using cold water instead of hot).

In your case, since you mentioned that your underwear was washed with detergent and dried, the likelihood of re-infection from wearing those specific pieces of clothing is low. However, it is essential to consider other factors that contribute to the risk of recurrent infections:
1. Sexual Partners: If you are engaging in sexual activity with partners who may still carry the infection or have not been treated, there is a significant risk of reinfection. It is crucial that all sexual partners are tested and treated simultaneously to prevent the cycle of infection.

2. Personal Hygiene: Maintaining good personal hygiene is important. This includes regular washing of underwear and ensuring that any sexual activity is conducted safely. Using protection, such as condoms, can significantly reduce the risk of transmission.

3. Follow-Up Testing: After treatment for gonorrhea, it is advisable to have follow-up testing to ensure that the infection has been fully cleared. This is typically recommended about 1-2 weeks after completing treatment. If symptoms persist or if there is any doubt about the effectiveness of the treatment, further testing may be warranted.

4. Avoiding High-Risk Behaviors: Engaging in high-risk sexual behaviors can increase the likelihood of contracting gonorrhea again. This includes having multiple sexual partners or not using protection consistently.

5. Education and Awareness: Understanding how gonorrhea is transmitted and the importance of regular screenings can help in preventing future infections. Many people may not exhibit symptoms, so regular testing is key, especially for sexually active individuals.

In summary, while washing your underwear properly reduces the risk of re-infection, it is not a standalone solution. The most effective way to prevent recurrent gonorrhea infections is through a combination of good hygiene practices, safe sexual behaviors, and ensuring that all partners are treated. If you have concerns about your health or potential reinfection, it is always best to consult with a healthcare provider for personalized advice and testing.
