Anthony Fauci contracted West Nile virus from a mosquito bite in his garden. The virus, first discovered in Uganda in the 1930s, has caused 2,000 American illnesses annually, leading to 1,200 neurological illnesses and 120 deaths. Despite 20 years of research, there is no cure or dedicated treatment, and vaccines for humans have not progressed beyond initial trials. Climate change is increasing the frequency of outbreaks, making the virus a growing concern.
