Thank you for your inquiry. From what we gather from the question, you were asking about the possibility of HIV transmission through blood from a squashed mosquito potentially entering your skin.
From the information provided, this scenario is determined to be No Risk (transmission of HIV is not possible in the given scenario).
First of all, it is worth mentioning that human immunodeficiency virus (HIV) is a specific kind of retrovirus that affects only humans, and therefore cannot be carried by mosquitoes.
Even if a mosquito feeds on a person living with HIV prior to coming in contact with you, the HIV would enter the insect's gut, which does not contain human T cells (1). Human T cells are necessary in order for the virus to replicate, so it is instead broken down by the mosquito's digestive system (1). Therefore, there is no risk of HIV transmission from the blood of a mosquito possibly entering your body.
Recommendation: No need for an HIV test with the scenario provided, refer to a healthcare professional for other health related questions
