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.
Bed Bug Best Management Practices (National Pest Management Association)
Scabies is caused by an infestation of the microscopic mite Sarcoptes scabei. Infestation is common, found worldwide, and affects people of all races and social classes. This mite burrows into the skin, causing intense itching and irritation. Skin between the fingers, the bend of the elbow or knee, and the shoulder blades are areas most often affected. The intense itching is accompanied by a rash.
