Detailed Answer:
Hello and Welcome to 'Ask A Doctor' service...
I've gone through your query in details...
I can understand your concern...

First of all, it's important to know if he's recently married. If yes, then both the partners need to be examined and investigated for STDs (this includes Standard STD screening tests including HPV). Based on the findings, treatment can be initiated.

Since it's spreading heavily, I'd recommend getting tested at first before deciding upon any specific treatment course as there are several different infections or even co-existing factors that can worsen the pre-existing infection.

Ideally, both of them should get checked up by either an STD specialist (Venerologist) or a Dermatologist followed by getting tested at first, further plan of management can be done based on the findings...

Generally speaking, if it's turned out to be HPV infection/outbreak, then Cryotherapy with liquid Nitrogen or curettage can be done. It's an OPD based treatment only, done by the Dermatologists then and there, but he may require multiple follow-ups to monitor on the progress.

There are other chemical agents also, like Imiquimod or Podofilox gel, but they require a longer time of treatment and outcomes are also quite mixed.

So, please go ahead with the Dermatologist/Venereologists check-up at first to exactly diagnose the case/s, necessary treatment can be done thereafter...

Let me know if I can assist you further.

Take Care
Kind Regards
