The National Health Commission (NHC) on Monday reported 59 cases in Fujian, including 24 in Putian and 32 in Xiamen, a large coastal city popular with tourists. On Tuesday, the two cities launched Covid mass tests for all residents.
Putian has a population of around 3 million, while Xiamen has a population of 5 million. Both cities have ordered residents not to leave the city for non-essential travel. Those with legitimate reasons for leaving must produce a negative coronavirus test taken within the last 48 hours. Long-distance coaches from the two cities have also been suspended.
On Tuesday, Xiamen imposed targeted closures in residential neighborhoods affected by the epidemic, with residents banned from leaving their apartments or complexes. It has also closed libraries, museums, bars, cinemas and gymnasiums, banned large-scale gatherings and canceled events celebrating the Mid-Autumn Festival, a three-day party that begins on Sunday.
Similar restrictions were also placed on Putian. The city has reported a total of 85 infections, including 30 children under the age of 10, the city government said at a press conference on Tuesday.
In Xianyou, authorities have placed more than 3,000 direct and secondary contacts of infected cases in quarantine, including a large number of schoolchildren, some of whom have been separated from their parents, according to Wu Haiduan, head of the county government.
“It’s a difficult problem when outbreaks occur in children,” Wu said. “If children can be quarantined independently, we quarantine them independently. If they need parents to accompany them by their side. , we organize their parents to stay in a room next to them so they can chat with each other. Of course, they can only chat in the next door. “
As of Tuesday, no related cases were reported outside of Fujian, but local governments across China are on high alert. The NHC estimates that about 30,000 people from Putian, the epicenter of the latest outbreak, have left the province in the two weeks leading up to Friday.
The weeklong vacation, known as “Golden Week” and starting on October 1, is one of the busiest times for traveling in China, with hundreds of millions of people expected to race the highways, trains and planes.
The latest outbreak in Fujian was first detected in students at a primary school in Xianyou. Since then, infections have been discovered in students at several preschools and primary schools.
In Putian, 8 kindergarten students and 28 primary school students were infected, according to the government.
Xiamen and Putian closed schools and kindergartens and ordered them to teach online.
Experts quoted by the state newspaper Global Times have called on the country to expand its Covid-19 vaccination program to cover children aged 3 to 12.
In Putian, the government urged schools to step up efforts to administer second doses of Covid vaccines to 12 to 14 year olds and to complete the vaccination of students aged 12 to 17 by Wednesday.
The Fujian outbreak has highlighted the growing challenge facing China’s ambitious zero Covid strategy, raising questions about its long-term sustainability.
Experts advising the government have said a father who recently returned from Singapore was the likely source of the outbreak, despite having been under a long, draconian quarantine.
The man arrived in Xiamen, the provincial capital of Fujian, on August 4, where he underwent 14 days of compulsory quarantine in a hotel. He spent an additional 7 days in central quarantine in Xianyou, before returning home for an additional week of health surveillance, according to the Putien government.
He had tested negative for the virus nine times during a 21-day quarantine, before testing positive on Friday – 37 days after entering China, according to state media.
Chinese authorities have not disclosed when, where or how the man caught the virus, but an incubation period of more than 21 days is highly unusual.
Researchers from the Guangdong Provincial Center for Disease Control and Prevention found that the Delta variant had an average incubation period of 4 days, compared to an average of 6 days for the original strain.
Some have asked on social media if the man contracted the virus after returning to Xianyou.
