If possible, there should not be any travel or movement right now. If that’s not possible, it is highly necessary to have strict measures to control the disease,” Yong Poovorawan, Head of the Centre of Excellence in Clinical Virology at the Faculty of Medicine, Chulalongkorn University, said on Wednesday at a press conference at the Public Health Ministry.
