Minister of Health Mam Bun Heng issued a directive instructing all municipal and provincial governors to strictly enforce quarantine on the borders and implement other administrative measures to prevent the spread of the new Delta variant of Covid-19. The directive came after at least 10 cases of the Delta variant, first discovered in India, were detected this month in migrant workers returning from Thailand through border checkpoints. Bun Heng, who is also head of the inter-ministerial commission for combating Covid-19, said quarantines at designated centres along the borders have to be strictly enforced for all inbound travellers to Cambodia. Transportation of all travellers and migrant workers to their hometowns for quarantine has been paused, he noted in the directive dated June 25.
