Colleagues from GSTT in collaboration with the Royal Free and St. George’s have just published a new paper evaluating the transmission dynamics of Omicron SARS-CoV-2 vs. previous variants in hospitalised inpatients in Infection Prevention in Practice. The key finding is that the median days to inpatient contact conversion were significantly fewer for Omicron SARS-CoV-2 when compared with previous variants (median 3 days for Omicron vs. 4 days for previous variants).
