Dr. Anthony Fauci, the former top U.S. infectious disease expert, was hospitalized for nearly a week with West Nile virus but is now recuperating at home and expected to make a full recovery. The 83-year-old likely contracted the virus from a mosquito bite in his backyard. West Nile virus is primarily spread through mosquito bites and can cause symptoms such as fever, headache, body aches, vomiting, diarrhea, and rash, though most infected individuals do not show symptoms. There are no vaccines or specific treatments for the virus, which can sometimes lead to serious, potentially fatal illnesses. Fauci, who was the public face of the U.S. COVID-19 response, continues to be a significant figure in public health discussions.
