On December 2, 2021, Shanghai reported two locally confirmed cases of COVID-19, which were mother-daughter relationships. (Previously reported: Shanghai added 2 new cases of local confirmed cases, and no association with the previous epidemic was found)

After genetic sequencing in the laboratory of the Municipal Center for Disease Control and Prevention, the results were Delta variants of the new coronavirus.

After comprehensive epidemiological investigation by experts and the search and comparison analysis of the virus gene database, it is believed that the source of infection of the two locally confirmed cases this time is not excluded from the possibility of infection caused by exposure to the environment contaminated with imported viruses from abroad.
