In May, 1955 the U.S. Government secretly released hundreds of thousands of yellow fever mosquitoes on the unsuspecting residents of the State of Georgia. The test was designed to show whether the insect could be used as a weapon of war, spreading disease across an enemy population. It was a a resounding success.
Because it’s theorized that zombieism is a blood borne illness similar to malaria, it stands to reason that mosquitoes may be able to transmit the sickness. Mosquitoes don’t suck the blood of dead animals or people, so they would probably not target zombies. But if a newly infected person is bitten in the minutes or hours before he dies, then the offending mosquito would be feeding on contaminated blood before passing on to a new victim.
So we’ve got that to look forward to.
