China has shared some information on its COVID-19 situation, but there is a need for more data from local areas, a senior World Health Organization official said on Tuesday, adding that it is "not unreasonable" for countries to take precautionary measures.
According to information available to the WHO, the "virus variants circulating in China have already been seen in Europe and elsewhere," said Hans Kluge, the WHO regional chief for Europe.
"We share the current view of the European Centre for Disease Control, (ECDC) that the ongoing surge in China is not anticipated to significantly impact the COVID-19 epidemiological situation in the WHO European region at this time," he said.
"But we cannot be complacent," cautioned Kluge, who oversees a region that includes 53 countries and extends from Greenland in the northwest to the Russian Far East.
He acknowledged that China has shared virus sequencing information, but stressed that the WHO needs "detailed and regular information," especially on local epidemiology and variants.
"It is not unreasonable for countries to take precautionary measures to protect their populations while we await more detailed information that is shared via publicly accessible databases," said Kluge.
He was referring to requirements imposed by several countries for people coming from China, including negative COVID-19 tests and proof of full vaccination.
"For those countries in our region introducing such precautionary travel measures at this time, we are calling for such to be rooted in science, proportionate and non-discriminatory," he said.
Over the past year, many countries in Europe have significantly reduced their "surveillance capacity" for COVID-19, according to Kluge.
In the first five weeks of 2022, variant information on 1.2 million cases was submitted as part of weekly surveillance data to WHO and its partner, the ECDC, he said.
However, this declined to about 90,000 cases in the last five weeks of 2023.
"We commend European countries that have maintained strong genomic surveillance - including Denmark, France, Germany, and the UK," he said.
"Indeed, recent data from some of these countries are starting to indicate the growing presence of the new XBB.1.5 recombinant virus that has already been spreading rapidly across the US," he added.
Kluge said health authorities are picking up XBB.1.5. variant cases in the region "in small but growing numbers."
"After three long pandemic years-with many countries grappling with overstretched health systems, shortages in essential medicines, and an exhausted health workforce-we cannot afford more pressures on our health system," he stressed.
