(HealthDay)—The risk for mortality is increased in association with infection with a new variant of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) designated a variant of concern (VOC-202012/1) in December 2020, according to a study published online March 10 in The BMJ.
Robert Challen, Ph.D., from the University of Exeter in the United Kingdom, and colleagues conducted a cohort study involving 54,906 matched pairs of participants who tested positive for SARS-CoV-2 in community-based COVID-19 testing centers between Oct. 1, 2020, and Jan. 29, 2021. Participants differed only on detectability of the spike protein gene using the TaqPath assay (a proxy measure of VOC-202012/1 infection).
The researchers found that for patients who tested positive for COVID-19 in the community, the mortality hazard ratio associated with infection with VOC-202012/1 compared with infection with previously circulating variants was 1.64. This represented an increase in deaths from 2.5 to 4.1 per 1,000 detected cases in this relatively low-risk group.
