HANOI -- Hanoi authorities detected communal transmission of COVID-19 on Friday, putting the Vietnamese capital on high alert as the city is hosting the twice-a-decade National Congress, attended by nearly 1,600 Communist Party delegates.
The country also saw a spike of communally transmitted infections in a northern province. The government announced 93 confirmed cases, about 80 of which were linked to a person infected with the U.K. variant -- a highly transmissible strain that has also been discovered in Japan.
