Hospital-acquired COVID-19 affects patients, workers, study saysWhile the absolute risk of acquiring COVID-19 in the hospital was low—up to 0.75% risk per day of exposure pre-Delta (B1617.2) variant—patients or healthcare workers (HCWs) with COVID-19 nonetheless can be factors in the spread of COVID-19, a study published yesterday in PLOS One says.The researchers looked at four UK teaching hospitals, where 66,184 patients were hospitalized and 5,569 HCWs were on the job from Jan 12 to Oct 2, 2020.
Of the patients, 1.4% had a positive test within the same period, and 10.5% of those (97) had their first positive test post-hospitalization at least 7 days after admission, wherein they were considered a nosocomial case.
