The re­cent COVID-19 out­break in Qing­dao, Shan­dong prov­ince, was un­likely to have orig­i­nated at the com­mu­nity level as no new pos­i­tive re­sult was found fol­low­ing city­wide nu­cleic acid test­ing, of­fi­cials said at a news con­fer­ence on Thurs­day af­ter­noon.

By 3:30 pm on Thurs­day, the city had col­lected and tested more than 10.4 mil­lion sam­ples and had re­leased more than 8.8 mil­lion re­sults. There were no ad­di­tional pos­i­tive re­sults be­yond those al­ready un­der quar­an­tine, said Sui Ruwen, the city’s vice-mayor and chief of the pub­lic se­cu­rity bureau.

The test­ing ef­fort, which aims to cover the to­tal pop­u­la­tion of 11 mil­lion res­i­dents, is ex­pected to be fin­ished on Fri­day, he said.

On Thurs­day morn­ing, the city re­ported one new con­firmed COVID19 case, its 13th since Sun­day. The case is an in­de­pen­dent virus in­fec­tion of a 40-year-old port worker whose test was pos­i­tive but who had showed no symp­toms three weeks ago.

“Gen­er­ally, the in­cu­ba­tion pe­riod of the virus ranges from one to 14 days, but there are also re­ported cases whose in­cu­ba­tion pe­riod lasted four weeks,” said Sun Yunbo, di­rec­tor of a med­i­cal ex­perts team or­ga­nized to treat the city’s novel coro­n­avirus, adding that the dock worker is an in­di­vid­ual case.

In ad­di­tion to the 13th con­firmed case, the pre­vi­ous 12 in the re­cent epi­demic, which started over the week­end, were closely linked to the city’s pul­monary hos­pi­tal. Some top health ex­perts said the risk of in­fec­tion spread­ing in­side com­mu­ni­ties is un­likely.

The rea­sons for the re­cent out­break should be an­a­lyzed by top health ex­perts in the coun­try, said Jiang Fachun, deputy di­rec­tor of the city’s dis­ease con­trol and pre­ven­tion cen­ter.

Wu Zun­you, chief epi­demi­ol­o­gist at the Chi­nese Cen­ter for Dis­ease Con­trol and Pre­ven­tion, said dur­ing an interview with Xinhua News Agency on Wed­nes­day af­ter­noon that ef­forts in the com­ing days should be fo­cused on the close con­tacts of cases in the pul­monary hos­pi­tal, es­pe­cially if there are close con­tacts that have not been found out and iso­lated.

He sug­gested that the reemer­gence of the virus in Qing­dao is not due to the tran­si­tion from au­tumn to win­ter, nei­ther is it re­lated to the eight-day Na­tional Day Hol­i­day de­spite the large num­bers of peo­ple who trav­eled dur­ing that time.

“Pri­or­i­ties for pre­ven­tion should be on wards in hos­pi­tals, es­pe­cially those re­ceiv­ing over­seas con­firmed cases, and the use of ma­jor med­i­cal equip­ment should also be iso­lated,” said Wu.

“Wear­ing face masks, keep­ing so­cial dis­tances and wash­ing hands fre­quently should be­come a daily rou­tine,” he added.

In re­sponse to the re­cent out­break in Qing­dao, Sui Zhen­hua, di­rec­tor of the Qing­dao health com­mis­sion, was sus­pended from his post and is be­ing in­ves­ti­gated, and Deng Kai, dean of the pul­monary hos­pi­tal, was re­moved, ac­cord­ing to the state­ments from the city gov­ern­ment on Thurs­day.
