Rural China braces for COVID infections

The peak of China's COVID-19 wave is expected to last two to three months, and will soon swell across the vast countryside where medical resources are relatively scarce, a top Chinese epidemiologist says.

Infections are expected to surge in rural areas as hundreds of millions travel to their home towns for the Lunar New Year holidays, which officially start on January 21, known before the pandemic as the world's largest annual migration of people.

China last month abruptly abandoned the strict anti-virus regime of mass lockdowns that fuelled historic protests across the country in late November and finally reopened its borders on Sunday.

The abrupt dismantling of restrictions has unleashed the virus on China's 1.4 billion people, more than one-third of who live in regions where infections are already past their peak, according to state media.

But the worst of the outbreak was not yet over, warned Zeng Guang, the former chief epidemiologist at the Chinese Center for Disease Control and Prevention, according to a report published in local media outlet Caixin on Thursday.

"Our priority focus has been on the large cities. It is time to focus on rural areas," Zeng was quoted as saying.

He said a large number of people in the countryside, where medical facilities are relatively poor, are being left behind, including the elderly, the sick and the disabled.

Authorities are working to improve supplies of antivirals across the country, with Merck & Co's COVID treatment molnupiravir expected to be available in China from Friday.

The World Health Organisation this week warned of the risks stemming from holiday travel.

The United Nations agency said China was heavily under-reporting deaths from COVID, although it is now providing more information on its outbreak.

China's foreign ministry said the country's health officials have held five technical exchanges with the WHO in the past month and have been transparent.

Health authorities have been reporting five or fewer deaths a day in the past month, numbers which are inconsistent with the long queues seen at funeral homes and the body bags seen coming out of crowded hospitals.

The country has not reported COVID fatalities data since Monday.

Officials said in December they planned to issue monthly, rather than daily updates, going forward.

Although international health experts have predicted at least one million COVID-related deaths this year, China has reported about 5000 since the pandemic began, one of the lowest death rates in the world.

Concerns over data transparency were among the factors that prompted more than a dozen countries to demand pre-departure COVID tests from travellers arriving from China.

Beijing, which had shut its borders from the rest of the world for three years and still demands all visitors get tested before their trip, has said it strongly opposes such curbs, calling them "discriminatory" and "unscientific".

Tensions escalated this week with South Korea and Japan, with China retaliating by suspending short-term visas for their nationals.

The two countries also limit flights, test travellers from China on arrival and quarantine the positive ones.

Japan's Chief Cabinet Secretary Hirokazu Matsuno said on Friday Tokyo will continue to ask China to be transparent about its outbreak, labelling Beijing's retaliation as one-sided, unrelated to COVID and extremely "regrettable".
