Spring brings beautiful flowers, warmer weather, and sunshine back to New York. Unfortunately, it's time for mosquitos to start their annual feasts, too. The risk level for contracting a mosquito-borne illness greatly depends on where you live in the state.

While West Nile Virus (WNV) has been the most headline-catching disease that mosquitos carry in the United States, there's other dangerous alternative as well. Eastern equine encephalitis (EEE), though very rare, is another very serious consideration. All five cases of EEE recorded in New York have been fatal.

While it is still very rare to contract WNV or EEE, there is currently no treatment or vaccine for either disease, which means the best protection is prevention. The NYSDOH recommends several precautions for New Yorkers to take, including using insect repellant, wearing long sleeves, checking window screens for damage, and to drain any standing water, including puddles or even birdbaths.
