WHO worried about surge of Covid cases in China amid lack of information

The head of the World Health Organisation said on Wednesday the agency is concerned about the risk to life in China amid the coronavirus' explosive spread across the country and the lack of outbreak data from the Chinese government.

WHO Director-General Tedros Adhanom Ghebreyesus said the agency recently met with Chinese officials to underline the importance of sharing more details about COVID-19 issues including hospitalisation rates and genetic sequences, even as the pandemic continues to recede globally since it began in late 2019.

Data remains essential for WHO to carry out regular, rapid and robust risk assessments of the global situation, Tedros said at a press briefing.

Tedros said he understood why numerous countries have recently taken measures against travellers coming from China, saying it's understandable that some countries are taking steps to prevent their citizens given the void of information about COVID-19.

WHO emergencies chief Dr. Michael Ryan said the testing protocols implemented by some countries were not a restriction against travel.

It's not an excessive measure based on individual countries' risk assessment, Ryan said.

He noted that for the past three years, China has had some of the world's harshest rules regarding COVID-19. The reality for China is that many countries (now feel) they don't have enough information to base their risk assessment, he said.

Earlier this week, Chinese officials sharply criticized COVID-19 testing requirements imposed on visitors from China and threatened countermeasures against countries involved, which include the US and several European nations.

We believe that the entry restrictions adopted by some countries targeting China lack scientific basis, and some excessive practices are even more unacceptable, Foreign Ministry spokesperson Mao Ning said at a briefing on Tuesday.

The WHO's Ryan added that there were continuing concerns about how Chinese officials are recording coronavirus deaths, saying that their definition, which only counts COVID-19 deaths if there is a record of respiratory failure, is too narrow.

Throughout December, China recorded only 13 official COVID-19 deaths, despite many thousands of cases every day and reports about overwhelmed hospitals, fever clinics and crematoriums.

A WHO expert group said on Wednesday that no worrying new COVID variants have been identified in China based on the information authorities have shared, including genetic sequences deposited into a public database.

The WHO said Chinese scientists have now shared more than 770 sequences, with omicron subvariants BA.5 and its descendants accounting for more than 97 per cent of all local infections. Globally, BA.5 variants comprise about 68 per cent of all sequences.

The European Centre for Disease Prevention and Control said it did not expect the surge of COVID-19 in China to affect the outbreak in Europe, given the high rates of vaccination across the continent.

It also noted that the variants spreading in China were already present in Europe, suggesting that any spillover from China would have a negligible impact.

Maria Van Kerkhove, the WHO's technical lead on COVID-19, said the agency was currently evaluating the significance of the variant known as XBB.1.5, which has recently comprised an increasing proportion of cases in the US.

Our concern is how transmissible it is, Van Kerkhove said. The more this virus circulates, the more chances it will have to change, she said, adding that further waves of transmission do not necessarily have to translate into more deaths, with the wide availability of vaccination and drugs.

Van Kerkhove said there is no data yet to prove that XBB.1.5 causes more severe disease, but that the WHO is working on a new risk assessment of the variant that it expects to release soon.
