As mosquito ranges expand, better monitoring is key to preventing disease

With summer heat comes pool parties, beach days, backyard cookouts, and, of course, swarms of bloodthirsty mosquitoes. But while insect bites have always been a side effect of time spent outdoors, the species doing the biting are changing in historically temperate regions like New England. As climate change makes these areas warmer and wetter, their ranges are expanding—and any diseases they carry come with them.
