The Ministry of Health announced on Wednesday the second-largest increase in daily infections in Vietnam, most in an epicenter in the northern part, while almost 100 of them were recorded in Ho Chi Minh City.
The country detected 414 community cases, including 398 in quarantined areas, the ministry said in a report the same day.
This is second-biggest daily case jump after the health ministry saw the steepest spike of 444 cases on May 25.
The nation recorded the third-strongest rise of 398 transmissions on Tuesday.
Bac Giang Province, which is the largest epicenter located in the north, reported 279 of the latest patients, while its neighbor Bac Ninh Province logged 27 cases.
Ho Chi Minh City registered 99 cases, its largest daily count this year, Ha Tinh Province four, Nghe An Province three, Ha Nam Province one, and Bac Kan one.
Vietnam has detected 8,411 locally-transmitted infections in 40 out of its 63 provinces and cities since the ongoing fourth virus wave erupted on April 27.
Bac Giang is leading the caseload with 4,680 patients, followed by Bac Ninh with 1,442, Ho Chi Minh City with 1,060, and Hanoi with 464.
Authorities in Ho Chi Minh City on Monday decided to extend the enhanced social distancing measures having put in place since May 31 by two weeks to stall escalating community spread, as over 80 patients have been confirmed on a daily basis since last weekend.
The Southeast Asian nation has recorded an accumulation of 11,635 infections as of Wednesday evening, including 9,980 domestic and 1,655 imported cases, according to the health ministry’s statistics.
The number of recovered patients has reached 4,590, including 47 reported on Wednesday, while 61 have died, most with severe pre-existing conditions.
Nearly five million people have been tested in this fourth wave, the worst so far.
Vietnam confirmed 106 community cases in the first wave from January 23 to April 16, 2020, 554 in the second from July 25 to December 1, 2020, and 910 in the third from January 28 to March 25, 2021.

It has received about 2.9 million AstraZeneca shots so far.
