The NSC met other security agencies to assess the current state of emergency which will expire on April 30, reports The Bangkok Post.
Speaking after the meeting, NSC secretary-general Somsak Roongsita said the meeting agreed that enforcement of the decree should be extended since the pandemic has not yet been brought under complete control.
The government will decide how long the extension will be, Gen Somsak said, adding it will also discuss preparations for the relaxation of restrictions with the National Economic and Social Development Council.
He said Prime Minister Prayut Chan-o-cha will call a meeting of the Centre for COVID-19 Situation Administration (CCSA) on Monday to decide whether to extend the state of emergency.
If the extension is agreed, the matter will go before the cabinet meeting on Tuesday for approval, Gen Somsak said.
He added that details regarding the relaxation of restrictions will be known after Monday’s meeting.
He also said the NSC will invite representatives from the business sector to give opinions on how to curb new infections if restrictions are relaxed.
A source at the NSC meeting said security agencies responsible for enforcing the emergency decree would propose the extension at Monday’s meeting following their assessment of the situation, as well as recent opinion surveys showing that most respondents want the state of emergency extended to prevent the spread of the virus.
Taweesilp Visanuyothin, spokesman of the CCSA, said there has been concern that a second wave of COVID-19 transmissions will erupt once life starts returning to normal.
He warned people not to go out, except when it is absolutely necessary, as they will risk contracting the virus and infecting their families.
Dr Taweeslip denied a report about the lifting of the curfew in 32 provinces in early May, adding any relaxation of the state of emergency must be approved by the cabinet.
On his Facebook account, Yong Poovorawan, head of the Centre of Excellence in Clinical Virology at the Faculty of Medicine, Chulalongkorn University, explained the criteria which would be used to decide which areas should be designated as coronavirus-free.
He said an area which is deemed to be virus-free must have gone at least 28 days without a new infection - double the 14-day incubation period for COVID-19.
