He said the communicable disease control committee had approved opening the borders.
The province would run preventive measures in closed areas, such as screening all those who arrive and depart or sending officials to check people suspected of carrying symptoms and normal people.
The province will continue to restrict people from coming out of their residences without necessary reason, he added.
The areas to continue closed are namely Bangla Road, Ban Bangtao, Ban Bang Chi Lao, and Pracha Samakkee community.
The boundaries would be opened on May 1, or by May 4, since the province needs to coordinate with central officials for this operation.
