The infectious diseases specialist urged French people to return to social distancing and mask-wearing, and said a 'return to normal' would probably be in 2022 or 2023.
Strain multiplies rapidly in respiratory tract, shows increased transmissibility
Fifty-six of the 73 Delta variant cases were registered in Aizawl, nine in Lunglei, five in Kolasib and three in Serchhip, the official said, adding that both the Alpha and Eta variants were reported
The doctor, despite being fully vaccinated, got infected with both Alpha and Delta variants of SARS-CoV-2, and the RMRC lab detected the double infection in the patient in May.
