Vietnam has said it detected its first locally transmitted cases of the coronavirus in 35 days, as authorities ordered tighter surveillance to prevent a new outbreak.
Four members of a family in northern Ha Nam province and one person in southern Ho Chi Minh City were infected, the health ministry said, having all been in contact with an individual who had returned from Japan and tested positive, despite clearing quarantine.
Authorities ordered provinces and state agencies to tighten screening and controls and contact-tracing efforts were launched after the community infections were found, state broadcaster Vietnam Television reported.
