Bed bugs are a type of insect that feed on human blood, usually at night.[7] Their bites can result in a number of health impacts including skin rashes, psychological effects, and allergic symptoms.[5] Bed bug bites may lead to skin changes ranging from invisible to small areas of redness to prominent blisters.[1][2] Symptoms may take between minutes to days to appear and itchiness is generally present.[2] Some individuals may feel tired or have a fever.[2] Typically, uncovered areas of the body are affected and often three bites occur in a row.[2] Bed bugs bites are not known to transmit any infectious disease.[5][7] Complications may rarely include areas of dead skin or vasculitis.[2]
Bed bug bites are caused primarily by two species of insects of the Cimex type: Cimex lectularius (the common bed bug) and Cimex hemipterus, primarily in the tropics.[3] Their size ranges between 1 and 7 mm.[7] They spread by crawling between nearby locations or by being carried within personal items.[2] Infestation is rarely due to a lack of hygiene but is more common in high-density areas.[2][8] Diagnosis involves both finding the bugs and the occurrence of compatible symptoms.[5] Bed bugs spend much of their time in dark, hidden locations like mattress seams or cracks in a wall.[2]
Treatment is directed towards the symptoms.[2] Eliminating bed bugs from the home is often difficult, partly because bed bugs can survive up to a year without feeding.[2] Repeated treatments of a home may be required.[2] These treatments may include heating the room to 50 °C (122 °F) for more than 90 minutes, frequent vacuuming, washing clothing at high temperatures, and the use of various pesticides.[2]
Bed bugs occur in all regions of the globe.[7] Rates of infestations are relatively common, following an increase since the 1990s.[3][4][6] The exact causes of this increase are unclear; theories including increased human travel, more frequent exchange of second-hand furnishings, a greater focus on control of other pests, and increasing resistance to pesticides.[4] Bed bugs have been known human parasites for thousands of years.[2]
