The Ministry of Transport said on Friday that it expects more than 2 billion passengers to take trips over the next 40 days, an increase of 99.5 per cent year-on-year and reaching 70.3 per cent of trip numbers in 2019.
There was mixed reaction online to that news, with some comments hailing the freedom to return to hometowns and celebrate the Lunar New Year with family for the first time in years.
Many others, however, said they would not travel this year, with worry of infecting elderly relatives a common theme.
"I dare not go back to my hometown, for fear of bringing the poison back," said one such comment on the Twitter-like Weibo.
There are widespread concerns that the great migration of workers in cities to their hometowns will cause a surge in infections in smaller towns and rural areas that are less well-equipped with ICU beds and ventilators to deal with them.
Authorities say they are boosting grassroots medical services, opening more rural fever clinics and instituting a "green channel" for high risk patients, especially elderly people with underlying health conditions, to be transferred from villages directly to higher level hospitals.
"China's rural areas are wide, the population is large, and the per capita medical resources are relatively insufficient," National Health Commission spokesman Mi Feng said on Saturday.
"It's necessary to provide convenient services, accelerate vaccination for the elderly in rural areas and the construction of grassroots lines of defense."
Infection peak reached
Some analysts are now saying the current wave of infections may have already peaked.
Ernan Cui, an analyst at Gavekal Dragonomics in Beijing, cited several online surveys as indicating that rural areas were already more widely exposed to Covid infections than initially thought, with an infection peak already reached in most regions, noting there was "not much difference between urban and rural areas."
On Sunday China will reopen its border with Hong Kong and will also end a requirement for travellers coming from abroad to quarantine. That effectively opens the door for many Chinese to travel abroad for the first time since borders slammed shut nearly three years ago, without fear of having to quarantine on their return.
Jillian Xin, who has three children and who lives in Hong Kong, said she was "incredibly excited" about the border opening, especially as it means seeing family in Beijing more easily.
"For us, the border opening means my kids can finally meet their grandparents for the first time since the pandemic began," she said. "Two of our children have never been able to see their grandpa, so we cannot wait for them to meet."
China's surge in cases has caused concern internationally and more than a dozen countries are now demanding Covid tests from travellers from China. The World Health Organisation said on Wednesday that China's Covid data underrepresents the number of hospitalisations and deaths from the disease.
Chinese officials and state media have defended the handling of the outbreak, playing down the severity of the surge and denouncing foreign travel requirements for its residents.
On Saturday in Hong Kong, people who had made appointments had to queue for about 90 minutes at a centre for PCR tests needed for travel to countries including mainland China.
Treatment to the fore
For much of the pandemic, China poured resources into a vast PCR testing program to track and trace Covid-19 cases, but the focus is now shifting to vaccines and treatment.
In Shanghai, for example, the city government on Friday announced an end to free PCR tests for residents from on 8 January.
A circular published by four government ministries Saturday signalled a reallocation of financial resources to treatment, outlining a plan for public finances to subsidise 60 per cent of treatment costs until 31 March.
Meanwhile, sources told Reuters that China is in talks with Pfizer Inc to secure a licence that will allow domestic drugmakers to manufacture and distribute a generic version of the US firm's Covid antiviral drug Paxlovid in China.
Many Chinese have been attempting to buy the drug abroad and have it shipped to China.
On the vaccine front, China's CanSino Biologics Inc 6185.HK announced it has begun trial production for its Covid mRNA booster vaccine, known as CS-2034.
China has relied on nine domestically-developed vaccines approved for use, including inactivated vaccines, but none have been adapted to target the highly-transmissible Omicron variant and its offshoots currently in circulation.
The overall vaccination rate in the country is above 90 per cent, but the rate for adults who have had booster shots drops to 57.9 per cent, and to 42.3 per cent for people aged 80 and older, according to government data released last month.
China reported three new Covid deaths in the mainland for Friday, bringing its official virus death toll since the pandemic began to 5,267, one of the lowest in the world.
International health experts believe Beijing's narrow definition of Covid deaths does not reflect a true toll, and some predict more than a million deaths this year.
