Ectoparasites - Lice

Introduction

These wingless insects live near the skin in hairy areas. Eggs are fixed to hairs (and to clothing fibres by the body louse). Lice bite and suck blood and this causes irritation. Body lice usually are found in those who are unable to change their clothes or bath regularly. Head and pubic lice may infect anyone.

Transmission

Transmission of lice is by being in close contact with an infected person.
