Assessing STD Risks After Using Public Hot Springs: What You Need to Know - Urology

I would like to inquire about the risks of sexually transmitted infections (STIs)?


Hello, doctor: Last Saturday, while staying at a hotel in Japan, I used the public bath to soak in the hot spring.
I sat on the bench in the bath without any clothing after rinsing it with body wash, but my genital area accidentally touched the bench.
Since that day, I have been experiencing a slight burning and itching sensation in my genital area.
Given that there were many people from Southeast Asia and Japan in the hotel, I would like to ask the doctor how likely it is to contract a sexually transmitted infection or other gynecological diseases in this situation.
Is the itching and burning sensation I experienced that day related to using the hot spring? Thank you.

Hello: Soaking in hot springs can potentially transmit infectious diseases, but the chances are low unless one's immune system is weakened.
Since you are already experiencing symptoms, it is advisable to seek medical treatment.
In the meantime, maintain cleanliness and dryness.
Wishing you good health.

Using public hot springs can raise concerns about potential exposure to sexually transmitted diseases (STDs) and other infections, particularly when it comes to skin-to-surface contact in communal bathing areas. While the risk of contracting STDs in such settings is generally considered low, it is essential to understand the factors involved and the symptoms you are experiencing.

Firstly, STDs are primarily transmitted through sexual contact, which includes vaginal, anal, and oral sex. The pathogens responsible for STDs typically require direct mucosal contact to spread effectively. In the case of using a public hot spring, the likelihood of contracting an STD solely from sitting on a bench, even if there was some skin contact with the area, is minimal. Most STDs, such as chlamydia, gonorrhea, syphilis, and HIV, do not survive long outside the human body and are not transmitted through casual contact or shared surfaces like benches in a hot spring.

However, your symptoms of burning and itching in the genital area are concerning and warrant further investigation. These symptoms could be indicative of a few different conditions:
1. Irritation or Allergic Reaction: The use of soaps, shampoos, or other bathing products in the hot spring could lead to irritation or an allergic reaction, especially if these products were not thoroughly rinsed off before you sat down.

2. Fungal or Bacterial Infection: Public bathing areas can be breeding grounds for fungi and bacteria, particularly in warm and moist environments. Conditions like yeast infections or bacterial vaginosis can cause similar symptoms of itching and burning.

3. Contact Dermatitis: If the bench was not adequately cleaned, or if there were residues from previous users, you might have developed contact dermatitis, which can cause redness, itching, and discomfort.

Given your symptoms, it is advisable to take the following steps:
- Monitor Symptoms: Keep an eye on your symptoms. If they persist for more than a few days or worsen, it is crucial to seek medical attention.

- Avoid Irritants: Refrain from using any potential irritants, such as scented soaps or lotions, until you determine the cause of your symptoms.

- Consult a Healthcare Provider: If your symptoms do not improve or if you develop additional symptoms (such as unusual discharge, increased pain, or fever), consult a healthcare provider. They can perform a physical examination and possibly run tests to determine if there is an underlying infection or condition that requires treatment.

- Practice Good Hygiene: After using public facilities, ensure you wash thoroughly with clean water and consider using a barrier (like a towel) when sitting on shared surfaces to minimize skin contact.

In summary, while the risk of contracting an STD from using a public hot spring is low, your symptoms suggest that you may be experiencing irritation or an infection. It is essential to monitor your condition and seek medical advice if necessary. Taking preventive measures in public bathing environments can also help reduce the risk of infections and ensure a safer experience.
