Causes Of Pubic Lice

Pubic lice are usually spread by close contact, including sexual activity. Using the blankets, towels, sheets, or clothing of people who have pubic lice can potentially lead to infection.

Adult lice lay their eggs (known as nits) near the epidermis on the hair shaft. The nits hatch into nymphs and begin feeding on the blood seven to ten days later. The lice can survive for one to two days without eating. [3]

Getting pubic lice from a toilet seat or furniture is quite unusual. They do not normally fall off from the affected areas. Pubic lice can also be detected in the brows or eyelashes of youngsters and is a symptom of sexual abuse. Children who share a bed with someone who has pubic lice may develop an infestation.

Other symptoms of pubic lice may include:

• Pale blue spots near the infested area.

Complications Of Pubic Lice

Diagnosis Of Pubic Lice

Pubic lice are usually diagnosed by a thorough inspection of the genital area. This can be carried out by the patient themselves. If pubic lice is suspected, seek medical help immediately. [5]
