Logicians and others often state: “It is impossible to prove a negative.” For example, there were those who suggested that the HIV virus could not be transmitted by mosquitoes. They pointed to the lack of any research proving that misquotes could not transmit the virus as evidence that there was a likely risk. However, the scientist had shown that there was not a single case yet where mosquitoes could be implicated—even in areas of high mosquito infestation.
