If someone was to kiss someone else with herpes, would approximately 3% H2O2 or 70% alcohol offer a proven risk reduction immediately after an exposure (within the hour for instance)?

I'm looking for reliable references.

  • Someone would have to do clinical study to answer that question, and I very much doubt they have. I also doubt that it would help avoid infection.

  • Can you please elaborate on why you don't think it would help?

  • A mouth-to-mouth kiss exchanges body fluids. There's no undoing that.

  • Interesting idea. But if the virus remained on the surface of the lips, or within the mouth, but hadn't been absorbed by mouth tissues, then I'm figuring it would prevent infection, and it wouldn't infect lower down the GI track. Are you thinking that infection usually occurs inside several minutes? Or that herpes isn't vulnerably to those antiseptics?

  • Those antiseptics most likely kill herpes virus, but whether they could reach every virus in the mouth and esophagus in sufficient concentration before it was able to infect isn't as likely. Comments aren't for extended discussions so I'd need to write an answer to really address this and I don't quite have time for that right now.

1 Answer 1


Both alcohols, ethyl and isopropyl, can kill several bacteria in 10 seconds or fewer in the lab, including Staph aureus, Strep pyogenes, E. coli, Salmonella typhosa, and Pseudomonas species, some of the bad actors in infections. For M. tuberculosis, it may take as long as five minutes of contact.  Many, but not all, viruses are goners, too, like HIV, hepatitis B, herpes, influenza, etc. Even some systemic bad fungal infections are susceptible, but again not all. But kissing means you put the virus into the mucose of the Respiratory and GI tract, rubbing the alcohol wont help the disease transmission.

Some references:
- This study is addressing the effectiveness of alcohol.
- This PDF
