SEOUL, South Korea — South Korea is shutting down indoor gyms offering intense workout classes and banning year-end parties at hotels in the greater Seoul area to fight the virus.

Prime Minister Chung Sye-kyun said Sunday authorities will also ban the operation of private music institutes teaching singing and wind instruments and saunas at public bath houses in the capital area. He said fitness centers, cafes and libraries operating inside apartment complexes will also be closed. The new steps will be effective from Tuesday.

The country reported 450 new cases on Sunday. South Korea on Thursday registered more than 500 new virus cases for the first time in eight months.
