City In China Tests 10 Million People After 13 COVID-19 Cases Are Found
The Chinese port city of Qingdao is under soft lockdown after a cluster of 13 COVID-19 cases was discovered last weekend.
In the past five days, health authorities say they conducted more than 10 million coronavirus tests of all Qingdao residents, all of which came back negative. Still, residents have been asked to remain at home, flights to Beijing have been canceled and travelers from Qingdao to other parts of China must quarantine.
All 13 cases were traced back to a Qingdao hospital, municipal authorities said Friday. The 13 include seven patients, three health workers, a dock worker and two people in close contact with the others. Two asymptomatic coronavirus carriers were also staying at the same hospital.
According to Qingdao's deputy mayor, prior to contracting COVID-19 many of the 13 patients also suffered from tuberculosis, making them vulnerable to coronavirus infection.
On Sept. 24, Qingdao reported that two dock workers tested positive for the coronavirus during a routine health check, but neither showed any symptoms. (China tallies asymptomatic carriers separately from confirmed COVID-19 patients until an asymptomatic individual develops fever or flu-like symptoms.)
The two dock workers had handled frozen imported seafood, a sample of which tested positive for the coronavirus on the surface of its packaging. One of the two dock workers began exhibiting symptoms on Oct. 14, nearly three weeks after first testing positive for the virus, and became the 13th patient in Qingdao's cluster.
News of the latest infections came just days after China's weeklong National Day holiday. An estimated 600 million people traveled domestically during the break, boosting the struggling tourism industry.
On Friday, the city of Guangzhou, more than 1,000 miles south of Qingdao, found one asymptomatic coronavirus carrier, a 40-year-old man, during a routine health check. Local health authorities say the case likely is linked to contact with an infected international traveler. The man works at a hotel used by the city for centralized quarantines and has been placed under medical observation at a local hospital.
Since March, China has instituted mandatory, centralized 14-day quarantine for any individual entering the country from abroad. Almost all COVID-19 cases in China now occur among inbound travelers.
