This week, a study suggested that midnasal swab specimens collected at home may be comparable to clinician-collected nasopharyngeal specimens for detecting SARS-CoV-2 in symptomatic patients. In another study, researchers compared different face coverings for limiting SARS-CoV-2 transmission. Elsewhere, researchers reported that SARS-CoV-2 antibodies wane early in patients with mild COVID-19, corresponding to a half-life of roughly 73 days. And in vaccine news, two new candidate vaccines showed promise in early trials. Catch up on these and all of our COVID-19 stories from the past week at the links below.
