Along with longer days and warmer temperatures, summer heralds much more robust mosquito populations in the northern hemisphere. Johns Hopkins mosquito expert Christopher Potter describes the three species of mosquitoes found worldwide and the illnesses they’re associated with.

Potter: There are three major species of mosquitoes: the anopheles mosquitoes those are the malaria mosquitoes. Those are the ones that can be a vector for something called the plasmodium parasite. There's the ades mosquitoes. Those are the ones that you might find more commonly in the United States although they are kind of traveling throughout the entire world. Those tend to vector viruses like chikungunya and there's culex mosquitoes, also found in the United States and those could be the West Nile virus.   :26

So besides the itchy bumps mosquito bites raise, transmission of some type of infection is also possible. Potter notes that malaria was seen last year in the continental United States and climate change is likely to exacerbate that issue. At Johns Hopkins, I’m Elizabeth Tracey.
