So as we all know in World War Z there is a zombie outbreak. Lots of people turn and what not. But I’m curious about the “ Camouflage” technique used. Which is if somebody appears sick then the zombie won’t bite. So what I’m asking is if a person had hiv/aids would the zombie not attack? With that then a good 70 million people be spared. But based off of my logic and counting all the non-curable STD’s then at least 25% of people in America will live. So wouldn’t that be a perfect solution to humanity surviving?
