Dr. Anthony Fauci, former director of the National Institute of Allergy and Infectious Diseases, is recovering at home after being hospitalized with West Nile virus, a spokesperson said. Fauci, a longtime public health official who became a household name as part of the White House Coronavirus Task Force, is expected to recover fully, the spokesperson said. About 1,000 Americans are hospitalized each year with the most severe form of West Nile virus, which is spread through the bite of infected mosquitoes. Another 1,500, on average, are diagnosed after developing symptoms, although experts estimate that as many of 80% of infections in the US are never identified.
