Shanghai says new Omicron subvariant found
People taking COVID-19 tests under scorching heat on Sunday.
The city of Shanghai has discovered a COVID-19 case involving a new subvariant Omicron BA.5.2.1, an official told a briefing on Sunday.
The case, found in the Pudong New Area on July 8, was linked with a case from overseas, said Zhao Dandan, vice-director of the city's health commission.
"Our city has recently continued to report more locally transmitted positive cases (of COVID-19) and the risk of the epidemic spreading through society remains very high," Zhao of the Shanghai health commission warned.
He said residents in several major Shanghai districts would undergo two rounds of COVID tests, from July 12-14, in a bid to bring potential new outbreaks under control.
The Omicron BA.5 variant, which is driving a new wave of COVID-19 infections overseas, was first discovered in China on May 13 in a 37-year old male patient who had flown to Shanghai from Uganda, according to the China Center for Disease Prevention and Control.
Variant BA.5 has been shown to have an accelerated rate of transmission and an improved immune escape capability, said Yuan Zhengan, a member of the city's expert advisery group on COVID prevention, speaking at the Sunday briefing.
But vaccination is still effective at preventing BA.5 from causing serious illness or death, he added.
