The lice can be seen with the unaided eye or, more clearly, with a hand-held microscope. The lice are mostly spread during sexual contact. They can also be spread by bedding, clothing, or non-sexual contact. Incubation period The eggs usually hatch in 7 days. The life cycle lasts about 2-3 weeks.
Adult lice can live for a few weeks on a host.
While there are living adult lice on an infested person, the lice can be passed on. Control of spread Sexual partners should be treated at the same time. Wash bedding, underwear, night clothes, and bath towels used while infestation was present in hot, soapy water or dry clean. Testing to exclude other sexually transmissible diseases is advisable. Treatment Insecticide in the form of a cream should be applied and treatment should be repeated after one week.
