China has rapid and extensive testing capabilities, and the health commission said more than 140,000 employees of “medical institutions, newly admitted patients and staff” have been tested in Qingdao since the cases were confirmed.
After the announcement, the National Health Commission (NHC) said mainland China had 21 confirmed cases of COVID-19 on October 11. The report did not include, but did not include any confirmed infections in Qingdao, and it was not immediately clear why.
The number of new asymptomatic cases, which China does not count as confirmed cases, rose to 32 from 23 a day earlier, the NHC said. He did not offer a breakdown on where the new asymptomatic cases were reported, although he did indicate that 29 of those cases involved people returning from abroad.
The coronavirus first appeared in the central city of Wuhan at the end of last year, and the city and its surrounding province of Hubei were cordoned off after an increase in cases towards the end of January.
China has since rebounded and daily COVID-19 cases have dropped significantly from those peaks, but the country remains on high alert.
In June, large areas of Beijing were mass tested after the capital, home to more than 20 million people, detected cases of the virus linked to a food market.
Qingdao has already locked down the Qingdao Chest Hospital as well as the emergency department of its central hospital. The buildings where people diagnosed with the disease live have also been cordoned off as part of the authorities’ containment measures.
China is also eager to be the first to deploy a vaccine against the coronavirus, with several companies in final trials. Although unproven, vaccines have already been administered to hundreds of thousands of key workers and soldiers.
The total number of confirmed cases of COVID-19 in mainland China now stands at 85,578, while the death toll remained unchanged at 4,634.
