Evaluating the dynamics of hospital COVID-19 contacts and subsequent conversion to SARS-CoV-2 infection: a multi-centre retrospective cohort study
We investigated the dynamics of COVID-19 contacts subsequent conversion to SARS-CoV-2 infection in an inpatient setting across three National Health Service (NHS) Trusts. 9.2% (476/5,156) COVID-19 contacts met inclusion criteria, were typable and tested positive for COVID-19. There was no significant difference between Omicron and non-Omicron contacts overall conversion proportions. Omicron contacts converted faster than non-Omicron contacts (median 3 days vs 4 days, P=0.03), and had significantly greater proportions of early conversions at day 3, 5, and 7 timepoints.
