Answer 1

Unlike mosquito borne diseases, HIV is unable to replicate within the mosquito’s gut and therefore is broken down. In humans, HIV binds to T cells and begins replicating. No T cells exist inside the mosquito’s gut and so the virus has no way of replicating or migrating to the mosquito’s salivary glands.
