The incubation period of pubic lice varies from person to person and can be as short as a few days or as long as a few months. Pubic lice are a human parasite that lives at the root of the pubic hair. Pubic lice is a common sexually transmitted disease, with a probability of transmission of approximately 95%. The more sexual partners you have, the higher the chance of developing pubic lice. If the onset of the disease is rapid, the symptoms of itchy pubic area usually appear in about 2-3 days of incubation, with individual differences in time. If the lice crawl directly into the pubic hair, symptoms usually appear within two or three days; if the larvae come into contact with the perineum, itchy symptoms will appear in about half a month or a month; if the eggs are transmitted, the incubation period is longer, up to several months. Once diagnosed with pubic lice disease, it is first recommended that all pubic hair be removed, and pubic lice cannot survive long without the environment on which they live. The prognosis is generally good with local application of drugs. It is recommended that patients pay attention to personal hygiene, change underwear regularly, bathe regularly, clean yourself and avoid an unclean sex life.
