The passenger took the VN814 flight operated by Vietnam Airlines from Cambodia's Siem Reap to Ho Chi Minh City on Tuesday before taking a connecting flight on the same airline to Japan.
After landing at Japan's Nagoya Airport, the passenger showed symptoms of high fever and was taken to a local hospital. Tests showed that he was positive for the virus that causes Covid-19.
After dropping off passengers at Nagoya Airport, the Vietnam Airlines plane returned to Tan Son Nhat Wednesday afternoon with 73 passengers and twelve crew members on board. All crew members and 51 passengers entering Vietnam on the VN341 flight were quarantined.
The plane was also disinfected. Two security staff of the airport and six service personnel in the C-class business room have also been quarantined because they'd come into close contact with the infected Japanese passenger.
