Ho Chi Minh City, the country’s largest coronavirus hotspot, registered 32 cases, followed by Dong Thap 2 and Long An 2.
Most of the patients suffered from severe underlying illnesses, said the Ministry of Health.
All the three localities are in southern Vietnam which is the epicenter of the fresh coronavirus outbreak in the country.
The new cases raised Vietnam’s COVID-19 death toll to 370, including 335 cases documented during the latest coronavirus outbreak that started in late April.
Most of the deaths were elderly patients who suffered from underlying illnesses such as hypertension, cancer, severe pneumonia, multi-organ failure, and diabetes (type II).
Vietnam is battling with the fourth outbreak of COVID-19, with the virus spreading to 58 out of 63 cities and provinces across the country and more than 60,000 new cases confirmed.
