"This was the first indication that the virus might be spreading among humans," he said. The death of the wife of an employee of the laboratory was reported to Asher by a man who worked at that time at the Wuhan Institute of Virology. According to a source, the Chinese authorities allegedly "hid for a month" information that the coronavirus is infectious for humans. This contributed to the outbreak of the epidemic, the official said.
