Appearance
Although bed bugs can be infected with at least 28 human pathogens, no studies have found that the insects are capable of transmitting any of these to humans. They have been found with methicillin-resistant ''Staphylococcus aureus'' and with vancomycin-resistant ''Enterococcus faecium'' , but the significance of this is still unknown.Investigations into potential transmission of HIV, MRSA, hepatitis B, hepatitis C, and hepatitis E have not shown that bed bugs can spread these diseases. However, there is some evidence that arboviruses may be transmissible.
Bed bug bites or cimicosis may lead to a range of skin manifestations from no visible effects to prominent blisters. Effects include skin rashes, psychological effects, and allergic symptoms.
Distribution
''C. lectularius'' is found all over the world in almost every area that has been colonized by humans.In the past, bed bugs were particularly an affliction of the poor and occurred in mass shelters. However, in the early part of the modern resurgence it was the tourist areas that were impacted. Today, bed bugs have conquered quite diverse locations, ranging from hospitals, hotels to trains, cruise ships and even airplanes. Most commonly, bed bugs travel as stowaways in luggage, although they can be transferred via furnishing and other belongings, as well by spreading to adjoining properties. Since there are no mandatory reporting requirements, exact figures on the occurrence of bed bugs are unknown and, due to the stigma often associated, many infestations are simply not reported.
Behavior
If feeding regularly, a female bed bug can lay between two and three eggs per day throughout her adult lifetime, which may last several months, allowing one female to produce hundreds of offspring under optimal conditions. The tiny (References:
