Gong said the viruses belong to the same group as those reported by Myanmar, adding that the virus gene sequencing results of 10 of the cases are exactly the same. No virus mutation has been found.
Dozens of new confirmed and asymptomatic COVID-19 cases have been reported in Ruili over the week during a citywide nucleic acid testing campaign.
