The concern about contracting HIV or other bloodborne diseases from mosquito bites is a common one, but it's important to clarify that the risk is virtually nonexistent. Mosquitoes are not vectors for HIV or other similar viruses that are transmitted through blood.
HIV (Human Immunodeficiency Virus) is primarily transmitted through specific bodily fluids such as blood, semen, vaginal fluids, and breast milk. The transmission typically occurs through direct contact with these fluids, often during sexual intercourse, sharing needles, or from mother to child during childbirth or breastfeeding. Mosquitoes, on the other hand, do not transmit HIV because of the way they feed and digest blood.

When a mosquito bites, it injects saliva into the host to prevent blood clotting while it feeds. The virus does not replicate within the mosquito; instead, it is broken down in the mosquito's digestive system. Therefore, even if a mosquito bites an individual who is HIV positive, the virus is not present in the saliva that is injected into the next person it bites. This is supported by numerous studies and health organizations, including the Centers for Disease Control and Prevention (CDC), which state that mosquitoes do not transmit HIV.

Furthermore, the same principle applies to other bloodborne diseases such as Hepatitis B and C. These viruses also require direct blood-to-blood contact for transmission. The likelihood of contracting these diseases from a mosquito bite is extremely low, if not impossible.

In your specific situation, if you killed a mosquito and noticed blood on your hand, the blood would not pose a risk of HIV transmission unless you had an open wound that came into direct contact with the blood of an infected person. Even then, the risk remains very low because the virus would not survive long outside the human body.
To summarize, you cannot contract HIV or other bloodborne diseases from mosquito bites. The primary modes of transmission for these viruses involve direct contact with infected bodily fluids. If you have further concerns about HIV or other sexually transmitted infections, it is advisable to consult with a healthcare professional for testing and guidance. Regular testing and practicing safe behaviors are the best ways to protect yourself from these infections.
