When Do The Symptoms Appear On Pubic Lice

When Do The Symptoms Appear On Pubic Lice ?      Pubic lice are not only found to grow in the pubic hair of humans, but also on other body parts where there is thick hair growth (such as hair on the legs, armpits, moustache, beard, eyebrows, or eyelashes).

      Pubic lice survive only on human blood and therefore, cannot stay away from a human host for more than 24 hours. Pubic lice infest a human host either as an egg, as a nymph or as an adult. When they begin to infest the pubic area, the pubic lice may generate certain characteristic symptoms or not produce any symptoms at all in the host’s body (asymptomatic infestation).

      The life-cycle of the pubic louse from the egg stage to the adult stage is 3 to 4 weeks. Once the eggs are laid by an adult female, they take about a week to hatch. Typically, the incubation period of the eggs of pubic lice is 7-8 days. The average life span of an adult female is 17 days while that of adult males is 22 days.

                                                 

       The period from the primary infestation to the time of the first symptom to appear is usually uncertain. Although no symptoms might appear in few people at all, it can take several weeks after getting infected by pubic lice for the first symptom to appear. Itching frequency and severity in the pubic area gets intensified around 2 or more weeks following the primary infestation. The appearance of tiny bluish grey lesions (maculae caeruleae) appears during the initial infestation period and may last for a few days.
