The government said that it expects to test up to 20,000 people in migrant worker dormitories in the coming days and has quarantined the workers to the dorms.
The outbreak, which started in the fishing hub of Samut Sakhon and its fresh markets, has now spread to more than six provinces and those that have visited Samut Sakhon in the past fortnight are being encouraged to get tested.
