China saw its first omicron cases in the community, igniting a mass testing blitz in the northern city of Tianjin as the country strives to maintain its zero-tolerance approach to Covid in the face of more transmissible variants.
The two cases in the port city were confirmed as being omicron by the Chinese Center for Disease Control and Prevention, after its local branch completed the genome sequencing, CCTV reported. The infections were from the same transmission chain but officials have yet to establish if the strain is the same as imported omicron cases reported earlier in Tianjin, according to the report.
