WASHINGTON: A new study examining air samples from hospital wards with COVID-19 patients has found the virus can travel up to 4m – twice the distance current guidelines say people should leave between themselves in public.
They found that the virus was most heavily concentrated on the floors of the wards,"perhaps because of gravity and airflow causing most virus droplets to float to the ground".High levels were also found on frequently touched surfaces like computer mice, rubbish bins, bed rails and doorknobs. They found that virus-laden aerosols were mainly concentrated near and downstream from patients at up to 4m – though smaller quantities were found upstream, up to 2.4m.
