The Ha Nam Center for Disease Control (CDC) announced the 28-year-old man’s test result on Thursday. Further tests would be required before he could be confirmed a Covid-19 case.

The man returned from Japan on April 7 and was quarantined at the Alisia Beach hotel in central Da Nang City. He tested negative for the coronavirus thrice during his stay.

On April 22 he returned home in Ha Nam and self-isolated himself. But on April 24 he began to display symptoms like coughing, fever and throat pain, and was taken to a local medical facility for testing.

Following the positive test result, he has been quarantined at the Ha Nam General Hospital, while his close contacts have been put in centralized quarantine zones. It has yet to be confirmed exactly how many people came into contact with the man since he came home.

Vietnam has recorded 2,865 Covid-19 cases so far with 35 deaths. No community transmission has been observed for over a month.
