The announcement by Macau's chief executive Ho Iat Seng came as the former Portuguese colony reported 10 confirmed cases of the virus and tight restrictions on movements in and out of the Chinese territory.
Residents have been instructed to wear masks when traveling around the city and been advised to stay home as much as possible.
Ho said he would be speaking to casino owners to discuss the closures. No immediate details were given as to when the suspension would begin.
