The incubation period of pubic lice infection varies and cannot be generalized. Those who are directly infected by the bugs may be able to feel the crawling sensation of the bugs after one hour, while those infected with eggs may take half a month to one month to hatch and mature, causing symptoms. Pubic lice are small insects that parasitize the genital area and other areas of body hair. They are mainly transmitted through sexual contact, but can also be transmitted through close contact, often causing intense itching and rashes in the genital area, which can easily lead to skin pigmentation changes, secondary infections, conjunctivitis, and other complications, and need to be treated with lotions or gels containing pyrethroids to be applied to the affected areas. Those who are directly infected with the bugs may feel the bugs crawling and laying eggs one hour after sexual contact. If the infected person is infected with pubic lice eggs or larvae, it will take some time to hatch and mature, and the symptoms such as itching may begin to appear in half a month to one month. If a person is suspected to be infected with pubic lice, it is recommended that he or she seeks medical evaluation in a timely manner, ensures good personal hygiene, and changes clothing regularly.
