Thai security authorities are on alert along the border with Myanmar after the neighbouring country reported more than 200 new coronavirus cases which compelled the government to close schools nationwide.
Authorities said all border passes in Mae Sot district and roads to Muang districts will be strictly screened.
Details of the operations will be confirmed by Naresuan Task Force commander Maj Gen Ukrit Nutkhamhaeng on Friday.
Mae Sot is the main gateway to Yangon, with the Moei River separating the two countries.
The long border in Tak makes it ideal for Myanmar people to cross the river and illegally enter Thailand in search of jobs.
Across the river, Myanmar workers disinfected government and private buildings in Myawaddy after the fresh outbreak.
Myanmar has reported more than 200 cases of the coronavirus since early last week after a month with no local transmission.
Most recent infections have been outside the biggest city, Yangon, and authorities believe they were more contagious than previously seen.
The country closed schools nationwide on Thursday as the number of cases rose, a decision broadly welcomed by parents worried about a rapid spread.
“The students have many years of studying ahead. Taking precautions against the virus is much more important for all of us,” said Thin Thin, a Yangon parent.
Khin Zaw Haling, a government official, said health measures must be followed to keep the threat at bay, after 70 new infections on Tuesday, Myanmar’s biggest daily rise.
“Now we have to again take more individual precautions,” he said.
With just six deaths and 586 infections since late March, the impact of the coronavirus has been relatively light in Myanmar, compared with Indonesia and the Philippines, which are reporting daily cases in the thousands.
Parent Swe Sin Hlaing said people in Myanmar had been careless and there was no room for complacency.
“We all have to be careful,” she said. “If we don’t take precautions, the situation would be uncontrollable.”
The new outbreak epicentre is Rakhine, about 500 kilometres from Yangon, with most cases tracked to the state capital of Sittwe, where a lockdown and curfew are in place.
Sittwe is also home to crowded camps where 100,000 Rohingya Muslims have been confined since violence erupted in 2012, with limited access to healthcare.
One new case in Yangon on Thursday was linked to Sittwe.
Not all parents are happy about schools closing again, however, and worry about disruptions.
“I’m afraid the students won’t pay attention to their studies if the schools keep closing,” said Aye Aye Htwe, 53.
