What Is Crabs Disease?
Reviewed: Dr. Gromatzky
7. Transmission
Pubic lice spread by crawling from one host to another. Thus, a person most often encounters them through sexual activity. Another means is through the sharing of towels, bedding, or clothing with an infected person.
Crabs cannot spread through casual contact like shaking hands. It also is extremely unlikely to encounter them on surfaces such as plastic chairs. It is theoretically possible for a louse attached to a shed pubic hair to crawl onto another person from a toilet seat, but this would be a rare occurrence.
