Beijing on Wednesday ordered people arriving from all other countries into a 14-day quarantine as China — where the coronavirus outbreak first began — is now seeing an increase in imported cases.

Zhang Qiang, a city government official, said at a Wednesday press conference that even those landing from “non-epidemic countries” will need to go into a 14-day quarantine.

The sprawling capital city had already required quarantine for people arriving from hard-hit countries including South Korea, Iran, Italy and Japan.

China’s President Xi Jingping visited Wuhan — the original epicenter of COVID-19 — on Tuesday and declared that it had “basically curbed” the spread of the disease.

The number of new infections had been on the downturn in recent weeks, but saw a slight uptick Wednesday because of an increase in imported cases.

Travelers arriving in Beijing for business trips must stay in a designated hotel and undergo a nucleic acid test for the virus, Zhang said.

People flying into Beijing Capital International Airport from high-risk countries are now handled separately from other arrivals, state media reported Tuesday.

Flights from Italy, Iran, South Korea and Japan will arrive at a designated area of the terminal, an airport staff member told Agence France-Presse Wednesday.

Travelers needing to be quarantined will be sent to the nearby New China International Exhibition Center, the staffer said.

Cases in Wuhan fell to a new low Wednesday, with 13 infections reported Wednesday, and only one other non-imported case recorded elsewhere in the country.

Wuhan and the surrounding province of Hubei have been under lockdown since late January in an unprecedented effort to keep 56 million people from traveling to other parts of China.

Twenty-two more deaths and 24 new cases were reported nationwide Wednesday, according to the National Health Commission.

Ten of those cases came from abroad — the majority from Italy, which has seen the greatest number of infections outside China.

In total, China has now reported 79 coronavirus cases imported.

Overall, 81,000 people have been infected in China since the start of the outbreak, with a large majority already recovered. A total of 3,158 people had died by Wednesday.

The outbreak has spread to over 100 countries and killed more than 4,000 worldwide.
