The woman, 38, had also returned from overseas in March and was found to be infected with the novel coronavirus. She was admitted to Phyathai 2 Hospital in Bangkok and recovered. Then she decided to return to her hometown.
However, from April 3-5 she became sick again and went for a test. The result showed that her throat was infected with Covid-19.
Another case was a 42-year-old construction worker who returned from Qatar on April 2.
Both cases are now under treatment in local hospitals. Authorities will try to trace people who might have been in close contact with them.
On April 8, a report showed that Chaiyaphum has 109 Covid-19 patients. Eight were new cases. The local government has asked its residents to strictly follow curfew directives to limit the spread of the virus.
