A 25-year-old Nevada man appears to be the first documented case of Covid-19 reinfection in the United States.
Genetic tests indicate the patient was infected with two different varieties of the virus, a team at the University of Nevada Reno School of Medicine and the Nevada State Public Health Laboratory reported.
The patient was first diagnosed with coronavirus in April after he had a sore throat, cough, headache, nausea and diarrhea, the researchers wrote in a pre-print study posted Thursday. He got better around April 27, and he tested negative for the virus twice afterwards.
He continued to feel well for about a month. Then, on May 31, he sought care for fever, headache, dizziness, cough, nausea and diarrhea. Five days later, he was hospitalized and required ongoing oxygen support. He was tested again for Covid-19 and the results were positive.
The Nevada researchers examined genetic material from both coronavirus specimens collected from the man. Their analysis suggests he had two distinct viral infections.
