better at cutting Covid risk at indoor events: Study
CNN:[3] Oxford is developing a COVID-19 vaccine with Serum Institute of India, and as the trials further, the CEO Adar Poonawalla has claimed that the vaccine will be available till the end of the year.[4] As per the CEO, the trials of the Covishield, the coronavirus vaccine, are showing promising results and may be available for production by December. However, he also added that the claim is being made on the basis of the data collected in the UK.[5] Face masks and limits on numbers are important, but good ventilation technology is the most essential ingredient of all in reducing the risk of the coronavirus spreading at public events indoors, according to a German study.[6] And researchers say the study’s results have implications for containing the epidemic among the broader population too.[7] Around 1,500 volunteers with face masks, hand sanitiser and proximity trackers attended an indoor pop-concert in Leipzig in August to assess how the virus spreads in large gatherings.Researchers simulated three scenarios with varying numbers of spectators and social-distancing standards, and created a computer model of the arena to analyse the flow of aerosols from infected virtual
spectators.
“The most important finding for us was understanding how crucial it is to have good ventilation technology. This is key to lowering the risk of infection,” said Stefan Moritz, leader of the RESTART-19 study at the University Medical School in Halle.
