On Thursday, Beijing reported a new COVID-19 case for the first time in almost two months. A 52-year-old man, who did not leave the Chinese capital, contracted the virus locally. The next day, authorities reported two more cases in Beijing.
Soon after their diagnosis, the city authorities launched an epidemiological investigation and checks. Later, the Beijing News newspaper reported that COVID-19 was found in samples taken from a cutting board for imported salmon in the Xinfadi market.
