Returning to your fortified encampment after a afternoon of scavanging supplies only to find your team/group/loved one's all turned into zombies, none with any signs of attack or struggle.
After finishing them off your inspecting the bodys and find no signs of physical bites, only small eraser sized bumps on areas of exposed skin.
As your sitting there wondering how this happened you feel something small crawling on your arm and a small sting, instinctively you smack at it, killing a tiny mosquito corpse in your hand and it suddenly comes to you that your screwed now.
