Comparison of Airborne SARS-CoV-2 Omicron and Pre-Delta Variants Around Infected Patients.

ABSTRACT: Transmissibility has increased during the evolution of SARS-CoV-2, possibly by improved airborne transmission. An increased transmission was noted also in many hospitals. We analyzed SARS-CoV-2 in room air of hospitalized Omicron infected patients and compared results with previous findings with pre-Delta variants to study if SARS-CoV-2 was more prevalent in patient rooms after the introduction of Omicron. Only 4 of 75 (5%) air samples, from 3 of 43 included patients, were positive during the early Omicron wave, compared to 14/120 (12%), from 10 of 60 included patients during the initial wave. No certain statistical difference between virus variants could be established, but the tendency was a lower occurrence at Omicron infected patients, also when adjusting for relevant confounders.
