Bedbug bite in Adult
Bedbugs have afflicted humans for thousands of years but became uncommon after World War II because of widespread use of modern insecticides. Beginning in 1995, a resurgence in bedbug infestations was noted, with rates almost doubling annually in North America, Western Europe, and Australia.
Increased national and international tourism, changes in pesticide use (including a prohibition on DDT), and use of recycled mattresses are thought to contribute to this epidemic of bedbug activity. Contrary to popular belief, cleanliness and hygiene have little impact on bedbug infestation. The insects are attracted to humans based on temperature and carbon dioxide production. Bedbugs are most prevalent in urban areas, likely due to population density and/or crowding.
At present, it is not believed that bedbugs are important vectors of disease transmission, such as human immunodeficiency virus (HIV) or hepatitis B or C. Patients with bedbug bites often come to medical attention seeking relief of resultant pruritus and skin lesions.
