Beijing's sudden pivot away from containing Covid-19 has caused jitters around the world, with the United States saying it may restrict travel from China following its decision to end mandatory quarantine for overseas arrivals.
China late Monday scrapped quarantine for inbound travelers from 8 January onwards, dismantling the last remaining piece of its stringent zero-Covid policy and ending some of the world's harshest border restrictions.
The move was greeted with jubilation by Chinese citizens, who rushed to book international flights, triggering a surge in ticket prices.
Hospitals and crematoriums across China continue to be overwhelmed by an influx of mostly elderly people.
AFP reporters saw dozens of mostly elderly Covid patients lying on gurneys in overflowing hospital emergency wards in Tianjin, 140 kilometers (87 miles) southwest of the capital Beijing Wednesday.
Medical staff are "pretty much all" expected to continue working despite testing positive for the virus, one doctor said.
Other countries have expressed concerns about the potential for new variants to emerge as China battles the world's biggest surge in infections.
US officials said late Tuesday they were considering Covid entry restrictions on travelers from China, after countries including Japan and India introduced PCR testing on arrival for Chinese passengers.
"There are mounting concerns in the international community on the ongoing Covid-19 surges in China and the lack of transparent data, including viral genomic sequence data, being reported from the PRC," the US officials said, referring to the People's Republic of China.
The United States is "considering taking similar steps" to countries such as Japan and Malaysia, they added.
Taiwan, a self-ruled island that China claims as its own, said Wednesday that it would also screen travelers from the mainland for the virus.
'Predictable and under control'
China's loosening of measures effectively brought the curtain down on a zero-Covid regime of mass testing, lockdowns, and long quarantines that has stalled its economy and triggered large-scale nationwide protests.
"Currently the development of China's epidemic situation is overall predictable and under control," foreign ministry spokesman Wang Wenbin said Wednesday.
"Hyping, smearing, and political manipulation with ulterior motives can't stand the test of facts," Wang added, calling Western media reporting on China's Covid surge "completely biased".
All passengers arriving in China have had to undergo mandatory centralized quarantine since March 2020. The period of isolation fell from three weeks to one week in June, and to five days last month.
The end of that rule in January will also see Covid-19 downgraded to a Class B infectious disease, allowing authorities to adopt looser controls.
Chinese immigration authorities said Tuesday they will resume issuing passports for tourism purposes from 8 January, after years of strict exit controls.
Tracking cases
The winter surge comes ahead of major public holidays next month in which hundreds of millions of people are expected to travel to their hometowns to reunite with relatives.
Chinese authorities have said the scale of the outbreak is now "impossible" to track and narrowed the criteria for defining Covid deaths.
China's Center for Disease Prevention and Control reported 5,231 new Covid cases and three deaths nationwide Wednesday — likely a drastic undercount since people are no longer required to declare infections to authorities.
Authorities are using data from online surveys, hospital visits, demand for fever medicines, and emergency calls to "make up for shortcomings in (officially) reported figures", disease control official Yin Wenwu said at a press briefing Tuesday.
With the country facing shortages of basic medicines, Beijing city authorities plan to distribute the oral Covid drug Paxlovid at local hospitals and community clinics. It remains extremely difficult to obtain for ordinary people.
The US-developed treatment was briefly available on e-commerce platform JD.com and delivery platform Meituan in the past few days before both ran out of stock.
