The cases are linked to the Xinfadi market in the southwest of the city, which supplies most of the fresh fruits and vegetables in the capital. The market, which sells meat and seafood, has been closed since Saturday.
The sudden resurgence of the virus in Beijing, which was once considered the safest city in the country, raised the possibility of a second wave of infections and the possibility of re-introducing the types of sweeping closures that previously caused much of the country to stop and close. Economy.
The authorities imposed a ban on 11 housing complexes near the market, and strictly prohibited anyone from entering or leaving. Population temperatures will be checked and reported on a daily basis, and their food and daily necessities delivered.
Beijing also conducted a comprehensive DNA test for the Coronavirus, and installed 193 sampling booths throughout the city. More than 76,000 people were tested on Sunday, while 59 people had a positive test result, Xu told a news conference on Monday.
DNA tests work by revealing the genetic code of the virus, and they can be more effective in detecting infections, especially in the early stages, than tests that examine the body’s immune response, although the latter are easier to do.
The Fengtai District collected samples from 8,950 people working in Xinfadi Market. So far, more than 6000 samples have been tested and all results are negative, according to Xu.
The authorities also tracked and collected samples from approximately 30,000 people who were in the market within 14 days before it was closed. Xu said the 12,000 tests conducted so far had shown negative results.
The Beijing government has ordered anyone who visited the market and their close contacts to stay at home for two weeks for medical observation. It also delayed the resumption of studies for primary school students, which was originally scheduled for Monday.
Several local officials, including the vice-president of Fengtai District, were fired after the outbreak.
The outbreak is not the first time that the virus has returned. In May, many places in the northeast of the country were quickly put under strict ban after imported cases caused an outbreak among the communities.
However, before the new group, Beijing reported only 420 local injuries and 9 deaths, compared to over 80,000 confirmed cases and 4,634 deaths nationwide, thanks to the strict travel restrictions imposed on it at the start of the epidemic.
Like most parts of the country, life in Beijing has begun to return to normal, with businesses and schools reopening, and crowds returning to malls, restaurants and parks.
The outbreak in Beijing will be the latest test of the coronavirus containment strategy in China.
Beijing authorities are still trying to track down the source of the latest outbreak, and pledged to conduct “the most severe epidemiological investigations”.
Zhang Yuxi, head of the market, told the state-run Beijing News on Friday that the virus had been discovered on a cutting board used by the imported salmon seller in the market, which had led to fears of widespread pollution. Several supermarket chains have removed salmon from their shelves, according to the Beijing Daily.
