Study says COVID-19 recurrence could be less than 0.1%Less than 0.1% of all COVID-positive patients in the Intermountain Healthcare system had probable or possible recurrence of SARS-CoV-2 infection, according to a PLOS One study yesterday.The full cohort of 23,176 COVID-19 patients was pared down to 1,301 patients who had at least one additional SARS-CoV-2 test 60 or more days after the initial diagnosis.
Almost 10% (122) had a positive test, of which 114 had sufficient data for recurrence evaluation (median test interval, 85.5 days).Using both clinical and cycle threshold (Ct) values, the researchers found that four patients had probable and six had possible COVID-19 recurrence.
