Treatment and Infection Risks of Viral Warts

Treatment and Transmission of Viral Warts

Hello Doctor: I have been undergoing cryotherapy for warts on the soles of my feet and fingers since early September, consistently every week without interruption.
However, after each cryotherapy session, the scabs do not fall off before the next treatment, and this has continued until now.
I would like to ask the following: 1.
Should I wait for the scabs to fall off before seeing the doctor for another cryotherapy session, or should I continue with the scheduled treatments? 2.
I previously mentioned to the doctor that I apply an adhesive bandage over the blisters after cryotherapy, and cover the soles with gauze and breathable tape.
Does this effectively prevent viral transmission? I am very concerned about transmitting it to my family and do not want to reinfect myself.
3.
Is there a possibility of infection if I touch the scabs from the cryotherapy? 4.
Do the scabs from cryotherapy carry the virus? Thank you, Doctor, for your kind answers.

1.
If it falls off, redo the procedure; if it doesn't, try to excise the epithelium as much as possible before performing cryotherapy for better results.
2.
To what extent is it possible? 3.
Yes, but the probability is lower.
4.
There is usually very little, almost none, dead skin.

When it comes to the treatment and infection risks associated with viral warts, particularly in the context of cryotherapy (freezing treatment), there are several important considerations to keep in mind.
1. Timing of Cryotherapy Sessions: It is generally advisable to wait until the scab from the previous cryotherapy session has fallen off before undergoing another treatment. This is because the scab serves as a protective barrier for the underlying skin as it heals. Continuing to freeze the area while the scab is still present can lead to unnecessary irritation and may hinder the healing process. It is essential to allow the skin to recover fully to maximize the effectiveness of the treatment.

2. Preventing Virus Transmission: Covering the treated area with a breathable bandage, such as an "OK band" or gauze, can help protect the site from external contaminants and reduce the risk of spreading the virus. However, it is crucial to maintain good hygiene practices. Washing your hands thoroughly after touching the treated area, avoiding sharing personal items like towels or shoes, and ensuring that any surfaces that may come into contact with the warts are cleaned regularly can further minimize the risk of transmission to family members or yourself.

3. Risk of Infection from Scabs: Touching the scabs from cryotherapy does carry a risk of infection, particularly if the scabs are not properly cared for. While the virus that causes warts (human papillomavirus, or HPV) is primarily present in the wart tissue itself, it is possible for the virus to be present in the scab. Therefore, it is advisable to avoid touching the scabs directly and to wash your hands immediately if you do.

4. Presence of Virus in Scabs: Scabs formed after cryotherapy can potentially harbor the virus, especially if they are still attached to the skin. It is important to treat these scabs with care. If you accidentally touch a scab, wash your hands thoroughly to reduce the risk of transferring the virus to other areas of your body or to others.

In summary, while cryotherapy is an effective treatment for viral warts, it is essential to follow proper protocols to ensure effective healing and minimize the risk of transmission. Always consult with your healthcare provider for personalized advice tailored to your specific situation. They can provide guidance on the best practices for managing your treatment and any concerns you may have about infection risks. Remember, prevention is key, and maintaining good hygiene and following your doctor's recommendations will help you manage your condition effectively.
