re: aids epidemic. mosquitoes. interesting point about the mosquitoes, but it appears that it has nothing to do with the size of the virus

"The results of experiments and observations of insect biting behavior indicate that when an insect bites a
person, it does not inject its own or a previously bitten person’s or animal’s blood into the next person bitten.
Rather, it injects saliva, which acts as a lubricant or anticoagulant so the insect can feed efficiently. Such diseases as yellow fever and malaria are transmitted through the saliva of specific species of mosquitoes. However, HIV lives for only a short time inside an insect and, unlike organisms that are transmitted via insect bites, HIV does not reproduce (and does not survive) in insects. Thus, even if the virus enters a mosquito or another sucking or biting insect, the insect does not become infected and cannot transmit HIV to the next human it feeds on or bites. HIV is not found in insect feces. "
