Thirty-one cases in Bac Giang Province and 18 in its neighboring Bac Ninh, are linked to the outbreaks in industrial parks, and all were isolated following contact tracing.

Of 11 new cases in HCMC, 10 are associated to a cluster that emerged May 26 at a Christian congregation called Revival Ekklesia Mission in Go Vap District, which has been placed under a lockdown since May 31. The transmission source of the remaining one remains unclear.

After Vietnam was hit by a new Covid-19 wave more than five weeks ago, 5,622 community transmissions have been recorded in 39 of its 63 cities and provinces, including major cities, industrial hubs and localities housing foreign tech giants.

Bac Giang and Bac Ninh now have the highest number of infections, at 3,089 and 1,093, followed by HCMC with 376.

On Sunday, Vietnam also saw 58 patients declared free from the coronavirus, raising total recoveries to 3,368.
