Vietnam's health ministry has reported 9,690 new coronavirus infections, a record daily increase and up from 7,334 cases yesterday.
Most of the new infections were detected in the epicentre Ho Chi Minh City and the neighbouring provinces of Binh Duong and Dong Nai, the ministry said.
Vietnam successfully contained the virus for much of last year but has since late April been faced with a surge in cases fuelled by the highly contagious Delta variant.
