Thailand’s Samut Sakhon province has confirmed another 900 new COVID-19 cases, from proactive screening of about 3,800 workers in local factories.

The province’s public health department says they are considering using the factories as quarantine facilities.

Dr. Opas Karnkawinpong, permanent secretary at the disease control department, said that the infections across Samut Sakhon and adjacent areas are 71% Myanmar nationals, 24% Thais and 5% other nationals.

These latest infections bring the total for Samut Sakhon to 2,296 cases, mostly resulting from active case finding and proactive screening in the province.

Due to this large increase in cases, officials are considering setting up quarantine areas and field hospitals in the grounds of factories, similar to those in the Central shrimp market. Infected people, who display no symptoms for more than ten days, will be considered to have recovered.
