All Carmarthenshire theatres have closed until the end of May.
The council said: "The safety of our workers and our audiences is of paramount importance in making this decision."
A further statement in relation to show cancellations and postponements will be issued as soon as possible.
All customers will be contacted directly.
The council statement added: "As you can imagine, we are receiving a lot of messages both online and via our box office. We are unable to respond to individual messages right now, but rest assured that we will be in contact with all customers as soon as possible, so please bear with us."
