BEIJING: The health officials have confirmed that the first case of a new coronavirus variant has been detected in China in a 23-year-old woman who arrived from Britain on December 14.
The new strain, which experts say potentially spreads faster than the original variant, has prompted travel restrictions on the UK by more than 50 countries — including China, where the coronavirus first emerged late last year.
The Chinese Centre for Disease Control (CDC) confirmed the development in a research note published Wednesday.
The patient was hospitalised on arrival as she showed mild symptoms. Health experts conducted a genetic sequencing of her test samples on December 24 ‘due to travel history from the UK and abnormalities in nucleic acid test results’,” the China CDC said.
The patient was found to have a strain different to those found in Shanghai or Wuhan earlier, and further testing confirmed it was the variant known as B.1.1.7 that has been spreading in the UK since October.
Health authorities have carried out contact-tracing, the CDC statement added.
China suspended direct flights to and from Britain indefinitely on December 24 because of the new strain.
British Prime Minister Boris Johnson has said the new variant “may be up to 70% more transmissible than the original version of the disease”.
But there is no evidence so far to suggest that infection with the new variant is more likely to lead to a severe case of Covid-19 or increase the risk of death.
