Air-borne transmission of SARS-Cov2 likely

Deccan Chronicle  

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. 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. Although the statistics of air borne transmission of SARS-CoV-2 is not clear yet, the virus is detected in the air for prolonged durations in certain circumstances.” At Covid-19 wards where the patients were treated, it was found that more number of patients meant generation of more virus particles. CCMB scientists, while taking the air samples, carried out live human experiments where volunteers were made to sit in personal protection kits to check if there were viruses around them.
