Dr. Fauci was hospitalized with West Nile virus and is now recovering at home, a spokesperson says

Dr. Anthony Fauci, the former top U.S. infectious disease expert, spent time in the hospital after being infected with West Nile virus and is now recovering at home, a spokesperson confirmed Saturday.

Fauci is expected to make a full recovery, the spokesperson said on condition of anonymity due to security concerns.

West Nile virus is commonly spread through the bite of an infected mosquito. While most people don't experience symptoms, about 1 in 5 can develop a fever, headache, body aches, vomiting, diarrhea, or rash, according to the Centers for Disease Control and Prevention. About 1 out of 150 infected people develop a serious, sometimes fatal, illness.

CBS News’ chief medical correspondent, Dr. Jonathan LaPook, wrote in a social media post that he spoke Saturday with Fauci, who said he was likely infected from a mosquito bite that he got in his backyard.
