RENO, Nev. — Nevada officials are reporting what may be the first documented case of coronavirus reinfection in the United States, following similar reports earlier this week from Hong Kong and Europe.
A 25-year-old Reno man with mild COVID-19 symptoms initially was found to have the virus in April, recovered and tested negative twice, and then tested positive again in June. He was much sicker the second time, with pneumonia that required hospitalization and oxygen treatment.
