Regarding HIV transmission by insects, what is the established evidence?

• A. HIV is highly likely to be transmitted by insects
• B. HIV transmission by insects is possible but not common
• C. HIV is not possible to be transmitted by insects
• D. HIV transmission by insects is not documented as a common mode of transmission

Answer: (D)

The main idea is that insects do not serve as a transmission route for HIV. For an insect to spread HIV, the virus would have to survive or replicate inside the insect and then reach its saliva to infect a new person, or be carried on the mouthparts in a way that transfers infection. Extensive research and public health reviews show there are no documented cases of HIV being transmitted by insects such as mosquitoes, flies, or bedbugs. HIV does not replicate in insects, and the virus is inactivated as it passes through the insect’s gut, so it cannot be passed on through a bite. Given this lack of evidence for any insect-borne transmission, the appropriate statement is that HIV transmission by insects is not documented as a common mode of transmission. In contrast, known routes like unprotected sex, sharing contaminated needles, and mother-to-child transmission remain the established pathways.
