Two Nigerian men brought to a Ho Chi Minh City hospital on Tuesday evening with fever-like symptoms are not having fever, according to doctors.
The pair arrived at Tan Son Nhat International Airport in HCMC on a Qatar Airways flight. They were taken to the Hospital of Tropical Diseases after being detected as having high temperatures by body temperature thermal imaging cameras at the airport.
They were kept in a quarantined zone of the hospital.
On Wednesday morning, doctors said the pair was not having fever and are in good health.
They are still kept under medical watch.
Nguyen Dac Phu, a spokesman for the Ministry of Health, called on passengers who boarded the flight QR964 from Nigeria to HCMC at seats No. 24, 25, 26 and 27 near the two Nigerian men (at seats No. 25B and 26D) to come to the nearest medical centers for health check or call to mobile number 0989 671 115 to be instructed on medical watch.
The ministry will send the list of these passengers to cities and provinces they stay so that local authorities could track down on them and keep them under medical watch.
