A side of West Nile scaremongering with your heat wave? Why not. According to the Brooklyn Eagle, the Department of Health has detected West Nile virus in city mosquitoes for the first time this season in three boroughs, more specifically in Old Town (Staten Island), South Jamaica/Rochdale Village and Auburndale/Pomonok (Queens), and East Williamsburg/Bushwick (Brooklyn).

Currently no human cases have been discovered, but the DoH is monitoring the situation with increased mosquito surveillance and larvae control efforts. Brooklyn 365 has some tips on how to guarantee a mosquito attack—or if you prefer the old fashioned way, the city has released these tips on avoiding one.

If you do get bit, stay calm—just watch out for flu-like symptoms (headache, fever, fatigue); West Nile can also cause encephalitis, a serious inflammation of the brain or spinal cord. Don't worry though, there's an app for keeping them away!
