Introduction
Pubic lice eggs that fall onto the bed may survive. Pubic lice are parasites that live on human hair, commonly found in the genital area. The main transmission routes include sexual contact, direct contact, and indirect contact. Sharing a bed with someone infected with pubic lice may also lead to infection. The primary symptoms include severe itching of the external genitalia and the presence of active lice or white lice eggs at the base of the pubic hairs.
Pubic lice eggs may survive if they fall onto a bed. The specific details are as follows:
Pubic lice are parasitic insects that live on human hair, most commonly found in the genital area. The main transmission routes include sexual contact, direct physical contact, and indirect contact. Sharing a bed with someone infected with pubic lice and having close contact may also lead to infection. Symptoms mainly include severe itching of the external genitalia and visible active lice or white lice eggs at the base of pubic hairs. If pubic lice eggs remain off the host for more than two days, they cannot survive independently. However, if the eggs fall onto a bed and a new host comes into immediate contact, the lice can transfer and continue to survive on the new host.
Body hair provides the habitat for pubic lice and their eggs. Before treatment, it is necessary to shave and burn all hair from infested areas. Contaminated clothing should be disinfected by boiling, and bed sheets and pillowcases should also be sanitized. Under medical guidance, medications such as sulfur ointment or Li-Jie Yi Sao Guang spray can be used. These treatments have strong insecticidal effects and can also relieve itching and inhibit local bacterial growth. Wear loose, comfortable underwear, preferably made of cotton.
