The task forces led by the Department of Health will focus on high-risk areas such as industrial parks, export processing zones and high-tech zones. Twenty-two of the task forces will work with leaders of People’s Committees in city districts and Thủ Đức City to enhance prevention measures in those areas. The other three task forces will support management boards in export processing zones, industrial parks and high-tech parks, including the Quang Trung Software Park.
