US Woman Carried Coronavirus for 105 Days Without Any Symptoms, Finds Case Study
News 18While most people infected with the novel coronavirus actively shed the pathogen for about eight days, scientists have reported an unusual case of a blood cancer patient who carried the virus for about 105 days, “and remained infectious for at least 70,” without experiencing any symptoms the entire time. “At the time we started this study, we really didn’t know much about the duration of virus shedding,” said study senior author Vincent Munster, a virologist at the National Institute of Allergy and Infectious Diseases in the US. “As this virus continues to spread, more people with a range of immunosuppressing disorders will become infected, and it’s important to understand how SARS-CoV-2 behaves in these populations,” Munster said. As the researchers studied samples that were regularly collected from the patient’s upper respiratory tract, they found that infectious virus continued to be present for at least 70 days after the first positive test, and the woman didn’t fully clear the virus until after day 105.
