GUANGZHOU, Oct. 18 (Xinhua) -- Genetic sequencing shows the new asymptomatic case in Guangzhou, capital of south China's Guangdong Province, is connected to an imported COVID-19 case, Guangzhou health authorities said Sunday.
The viral sequence of the 40-year-old man surnamed Wang, who works in a hotel in Huadu District, where overseas arrivals undergo concentrated quarantine, is highly homologous to that of an imported case, who stayed in the hotel earlier this month, according to Guangzhou Municipal Health Commission.
