A Government spokesman said today (November 24) that the Leisure and Cultural Services Department (LCSD) will implement a further anti-epidemic measure at its performance venues from November 30. If performers are not able to wear masks during a performance with a live audience, they must take a Government-recognised coronavirus disease 2019 (COVID-19) test 72 hours prior to their performance. They can only participate in the performance after they have obtained a negative test result in order to protect audiences.
