Rayong provincial authorities allowed markets to reopen on Thursday after they were ordered closed following a surge of Covid-19 infections in the eastern region.
The province has seen no new cases for three consecutive days.
Deputy provincial governor Anan Nakniyom said the Covid-19 situation was improving, although the province will remain a "maximum and strict control" zone until the Centre for Covid-19 Situation Administration (CCSA) declares otherwise.
He said easing Covid-19 restrictions in Rayong and a change of status from "maximum and strict control" zone to "control zone" was expected to be discussed by the CCSA on Friday.
However, Covid-19 checkpoints and strict screening would remain in place to curb the spread of the virus because the number of infections nationally was still high.
The surge of infections in Rayong was originally linked to illegal gambling dens.
Assistant CCSA spokeswoman Apisamai Srirangsun said the number of Covid-19 infections would be looked at when the CCSA meets today to consider easing restrictions.
However, she stressed the CCSA would only provide guidelines and provincial authorities would have to implement disease control measures that fit their own circumstances.
She said that large gatherings would still be banned and promotional events for Chinese New Year celebrations next month might have to be suspended.
"Please wait for the CCSA's decision," she said.
The relaxing of restrictions will be proposed at the CCSA meeting chaired by Prime Minister Prayut Chan-o-cha for approval today.
They include longer dine-in hours, the serving of alcohol in restaurants and the reopening of schools on Monday.
Dr Apisamai also said the number of confirmed cases linked to the cluster surrounding Techin Ploypetch, better known as DJ Matoom, stood at 24 with two others pending confirmation.
The number of high-risk contacts was 113 and the number of low-risk contacts was 53.
She said another cluster linked to a social gathering at a restaurant in a Bangkok shopping mall had emerged and was being investigated by the Department of Disease Control.
Seven cases linked to this cluster were confirmed and more than 200 people were identified as at-risk, she said, adding that an active case search would be carried out for this group.
She said Nakhon Pathom and Trat were free of new infections for seven days and their status had been changed from "maximum control" to "close surveillance" zones.
Meanwhile, the Office of the Basic Education Commission (Obec) said online learning will be allowed for students who want to continue studying at home if they have health concerns related to the virus.
Obec secretary-general Amporn Pinasa said schools are ready to reopen and have prepared coronavirus-preventive measures beforehand.
However, he said schools in Bangkok, Nonthaburi, Pathum Thani and Samut Prakan will have to observe social distancing by limiting the number of students per class to 25.
