Infestations of Public Health Importance
Lice are parasites of warm-blooded animals, including man. Head lice are not known to transmit any human pathogens. The chief human health concerns associated with head lice are skin irritation at the feeding site, secondary bacterial infections from scratching, and the psychological "trauma" of the infestations.
Bed bugs, small wingless insects that feed solely on blood, are increasingly becoming a problem within residences of all kinds, including homes, apartments, hotels, cruise ships, dormitories and shelters. While bed bugs do not carry disease, their bite can cause allergic skin reactions in susceptible individuals.
