Pathophysiology and etiology of bedbug bites?
Bedbug infestations seem to be increasing around the world at an alarming rate, possibly due to insecticide resistance. Resistance to pyrethroid insecticides is already widespread in the United States. The bedbug occurs in aggregations when conditions are favorable, but the arthropods disperse when conditions are unfavorable. New tactics may be needed for this escalating public health concern in locations with high occupant turnover, such as hotels, hospitals, and nursing homes. What is the pathophysiology and etiology of bedbug bites?
@riya The mechanism of skin injury by arthropods depends on the structure of the mouthparts. These insects are categorized as vessel feeders if they insert the tip into a capillary or as pool feeders if they feed on the extravasated blood from damaged tissue. They often inject different pharmacologically active substances (eg, hyaluronidase, proteases, kinins), which may cause different skin reactions (eg, erythema, wheal, vesicle, hemorrhagic nodule).
Bedbugs can be seen anywhere, but they tend to occur in environments in disarray. Old furniture makes an excellent home for bedbugs. These insects also like to hide in the seams and folds of mattresses and in bed frames and springs.
