SHANGHAI: China on Saturday marked the first day of “chun yun”, the 40-day period of Lunar New Year travel known pre-pandemic as the world’s largest annual migration of people, bracing for a huge increase in travellers and the spread of Covid-19 infections.

This Lunar New Year public holiday, which officially runs from Jan 21, will be the first since 2020 without domestic travel restrictions.

Over the last month China has seen the dramatic dismantling of its “zero-Covid” regime following historic protests against a policy that included frequent testing, restricted movement, mass lockdowns and heavy damage to the world’s No.2 economy.

Investors are hoping that the reopening will eventually reinvigorate a $17-trillion economy suffering its lowest growth in nearly half a century.

But the abrupt changes have exposed many of China’s 1.4 billion population to the virus for the first time, triggering a wave of infections that is overwhelming some hospitals, emptying pharmacy shelves of medicines and causing long lines to form at crematoriums.

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 99.5pc year-on-year and reaching 70.3pc 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.”

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.
