Can Bed Bugs Transmit HIV?
It’s unclear if bed bugs can transmit HIV. The only way to know for sure is to find out if an infected person has been bitten by a bedbug. If so, the person has to be within a few hundred feet of the infected person. The infected person must also live in the same household as the bedbugs. However, it may be possible. Further studies are needed to confirm whether bedbugs are capable of transmitting human disease.
It is hard to know how long bedbugs are infected, as the infection can last for days. It can be as long as 8 days in the gut of Cimex hemipterus, or as short as four hours in Cimex lectularius. The bites are often multiple and may be in a linear pattern.
Researchers have found no evidence of HIV transmission by bedbugs. However, it’s possible they harbor a drug-resistant bacterial infection called MRSA. Although the two bacteria are not mutually transmissible, this doesn’t mean bedbugs are immune from HIV. It is still possible to contract an infection from bedbug bites, but it is unlikely.
Although it is unlikely to transmit HIV through bedbug bites, these insects may still transmit the disease mechanically. For example, an insect may begin feeding on an HIV-infected individual and then be interrupted for some reason. When this happens, the insects may move on to another person to complete the meal. In this case, the insect may transfer fresh blood on its mouthparts or regurgitate blood from a previous meal.
