Of the 11 new cases, four are health care workers, according to Chinphu.
Da Nang, a popular resort city in Vietnam, has seen a recent increase in coronavirus cases since July 25 when a local man tested positive for the virus. Prior to that, Vietnam had gone 100 days without recording a single locally transmitted infection.
The recently confirmed cases led Vietnam's Prime Minister Nguyen Xuan Phuc to demand that contact tracing be ramped up and large-scale testing conducted across the city.
Around 80,000 tourists – mostly domestic travelers – in Da Nang with be evacuated over four days due to the latest outbreak.
The state-run media outlet added that the country’s Ministry of Health has sent experts to Da Nang to help the city find the source of the infection and contain the outbreak.
The 11 new cases brings the total number of cases in Vietnam to 431. The death toll remains at zero.
