Vietnam documented a total of 43 new cases of novel coronavirus disease (COVID-19) on Wednesday, including 42 local infections and one imported patient who was quarantined upon arrival, the second-largest single-day increase in cases since January.
Vietnam reported two new coronavirus patients on Wednesday morning, both registered in the central province of Quang Nam and traced to Da Nang, a neighboring city that is the country's outbreak epicenter.
On Wednesday night, 41 cases were documented, including 34 in Da Nang, four in Lang Son Province, two in Bac Giang Province, and one imported case quarantined upon arrival, according to the National Steering Committee for COVID-19 Prevention and Control.
Eleven provinces and cities in Vietnam have now registered at least a local COVID-19 infection, with Bac Giang and Lang Son being the latest additions to the list.
The six patients from Bac Giang and Lang Son are relatives, aged 10 to 41, who recently returned from a trip to Da Nang. They are now quarantined and treated at the National Hospital for Tropical Diseases in Hanoi.
The 34 patients in Da Nang include 32 traced to Da Nang Hospital — the city's largest cluster of infections, one linked to Da Nang Hospital for Women and Children, and one resident in Lien Chieu District.
They are aged one to 75.
The remaining patient is a 44-year-old man who arrived in Ho Chi Minh City from Russia on the flight IO4405 on July 11 and was quarantined upon arrival at the airport. He is now hospitalized in the southern province of Ba Ria-Vung Tau, around 90 kilometers east of Ho Chi Minh City.
Eighteen passengers on the repatriation flight have now been diagnosed with COVID-19.
The Southeast Asian country announced the recovery of three COVID-19 patients on the same day.
Vietnam has recorded 713 COVID-19 patients as of Wednesday night, including 309 imported cases quarantined upon arrival at airports, the Ministry of Health said.
The country has announced 381 recoveries and eight virus-related deaths that all had serious pre-existing conditions.
Vietnam on July 31 documented a total of 82 COVID-19 patients, including imported cases, the largest daily spike since the virus first hit Vietnam in January this year.
Two hundred and sixty-four local infections have been associated with Da Nang since July 25, when Vietnam confirmed the first local transmission after having gone 99 days with no documented community spread.
The 264 cases consist of 192 in Da Nang, 46 in Quang Nam, three in Quang Ngai Province, three in Dak Lak Province, two in Dong Nai Province, eight in Ho Chi Minh City, four in Lang Son Province, two in Bac Giang Province, two in Hanoi, one in Ha Nam Province, and one in Thai Binh Province.
Vietnam is in control of the outbreaks in Da Nang and Quang Nam, the National Steering Committee for COVID-19 Prevention and Control said.
