Thailand will extend the suspension of its quarantine waiver program and bring in new restrictions after a jump in new coronavirus cases linked to the omicron variant, the government’s COVID-19 task force said on Friday.

New applications for Thailand’s “Test & Go” quarantine waiver scheme will not be approved until further notice to stem the increase of coronavirus infections, said Taweesin Visanuyothin, the spokesman of the COVID-19 task force.

But existing applicants can still enter Thailand without quarantine until Jan. 15, he said.

“We can still make changes if the situation improves, but for now we have to learn more about omicron,” Taweesin said.

Due to concerns over omicron, Thailand had halted the waiver program since Dec. 22 and also most of its “sandbox” schemes, which requires visitors to remain in a specific location for seven days but allow them free movement during their stay, except for the resort of Phuket.

To curb local virus transmissions, alcohol consumption in restaurants will be halted after 9 p.m. in eight provinces including the capital Bangkok from Sunday, and banned in the country’s other 69 provinces, Taweesin said.

“Social drinking is the cause of the virus spread. Measures to restrict this will help curb the spread,” he said.

Thailand reported 7,526 cases of the coronavirus on Friday, the highest number since early November and more than double the number on Jan. 1.
