It has been almost 40 years since yellow fever was killed off here in america but now its back with the return of its host, the yellow jacket mosquito. It was wiped out with the help of DDT which seemed at the time to be the only way to keep it in check. I hope they have a new and improved way to kill them off or we could have thousand if not millions of deaths in north america from the virus it spreads. Even thou it was only found in San Francisco, the city is already asking the pubic in around the city to get rid of any standing water before it becomes a full blow out break. I find it weird that people in San Francisco started attacking people like Kevin Rose and Google for being parasites and now this shows up. Maybe they will know the real definition when it get a hold of them. Do you think this was released on purpose or a old foe finally came back from the dead? Leave your comments below.
