VARIANT "SOUP"
Xu Wenbo, head of the virus control institute at China's Centre for Disease Control and Prevention, said last week that hospitals across the country would collect samples from patients and upload the sequencing information to a new national database, allowing authorities to monitor possible new strains in real-time.
More than 130 Omicron sublineages have been newly detected in China over the last three months, he told journalists.
Among those were XXB and BQ.1 and their sublineages, which have been spreading in the US and parts of Europe in recent months as a swarm of subvariants has competed for dominance worldwide.
However BA.5.2 and BF.7 remain the main Omicron strains detected in China, Xu said, adding that the varying sublineages would likely circulate together.
Flahault said "a soup" of more than 500 new Omicron subvariants had been identified in recent months, although it had often been difficult to tell where each had first emerged.
"Any variants, when more transmissible than the previous dominant ones - such as BQ.1, B2.75.2, XBB, CH.1, or BF.7 - definitely represent threats, since they can cause new waves," he said.
"However, none of these known variants seems to exhibit any particular new risks of more severe symptoms to our knowledge, although that might happen with new variants in the coming future."
