The two crew members were tested for the virus after visiting the Pa Daeng brew house in Sattahip district. On Sunday, medics at Abhakornkiatiwong Hospital in Sattahip were reportedly ordered to check all 500 Navy personnel stationed on the Chakri Naruebet.
The Navy has not yet confirmed whether any of the crew are infected with Covid-19, Thai media reported on Monday.
However, the Navy said that if the two suspected cases are confirmed positive for Covid-19, all crew on board the ship would be quarantined.
