All public transportation including flights cannot enter or leave northern Quang Ninh Province from Thursday following the resurgence of Covid-19 transmissions.
The move came after the health ministry confirmed 84 community transmissions after 55 clean days, including 11 employees at Van Don International Airport. The others are workers of a company in nearby Hai Duong Province.
