COVID-19 transmission rate in train carriage decoded

Scientists have examined the chances of healthy people catching COVID-19 in a train carriage with a single infectious person, and have found that a safe social distance of more than one metre is required for an hour spent travelling together with the individual. The researchers, including those from the Chinese Centre for Disease Control and Prevention, assessed high-speed train routes in China, and found that for passengers sitting within three rows (widthwise) and five columns (lengthwise) of an infected person, between zero and ten percent caught the disease.
