Hyderabad: Sars-Cov-2 virus samples have been found in the hospital air of Covid-19 wards but not in non-Covid 19 wards, according to a CSIR-Centre for Cellular and Molecular Biology study. Three hospitals each from Hyderabad and Chandigarh participated in the study.
In the study, researchers found the virus in infectious aerosols measuring the size of less than 5µm. The smaller sized aerosols could get formed due to evaporation of water from larger respiratory droplets. Scientists from CCMB state that the smaller sized aerosols could stay suspended in air for longer durations of more than 2hours and were found to travel longer distances of 2meters.
Dr Dr Rakesh Mishra, director of CCMB says, “Our research from hospitals has raised questions as to whether the distance travelled by the virus of 1 or 2 meters is safe or not. There is emerging evidence indicative of the possibility of air-borne transmission of SARS-Cov2. Although the statistics of air borne transmission…
