Mosquito Dangers Have Changed
Do you remember ever worrying about mosquito diseases when you were a kid? Couldn't you get bitten hundreds of times and never get sick? Yes. But that isn't because mosquitoes didn't spread dangerous viruses when you were younger. You can go into the woods right now and get bitten by a hundred mosquitoes and not get sick. That's because not every mosquito that bites you is carrying a human pathogen. And not every species of mosquito can carry every kind of dangerous mosquito-borne virus. Let's take a look at this problem and see what we can learn.
In the United States, the two mosquito species most responsible for the spread of dangerous viruses are the Aedes aegypti and Aedes albopictus. That isn't to say that other mosquitoes can't spread illnesses. These are just the two that are considered to be the most medically important. But mosquitoes in the genus Culex, like C. pipiens, C. tarsalis, and C. quinquefasciatus can give those two Aedes mosquitoes a run for their money because Culex mosquitoes are connected to the spread of West Nile virus which claims lives in the United States every year. To make things more complicated (and you're probably thinking that isn't possible) there is an Aedes mosquito that can spread West Nile virus. It is the Aedes atropalpus, otherwise known as a North American rock pool mosquito. Does this all sound difficult to understand? That's only because it is.
