Experts had earlier put the figure at more than 120, citing the results of tests conducted in Equatorial Guinea.
According to Dr. Nguyen Trung Cap, deputy director of the hospital, nine patients are currently in a challenging situation, with six of them showing signs of lung damage and three suffering from malaria.
The remaining 11 positive COVID-19 cases are now in stable condition.
Vietnam Airlines conducted a special flight to evacuate 219 Vietnamese guest workers in distress from Equatorial Guinea, and the aircraft landed at Noi Bai International Airport in Hanoi on July 29. More than 120 workers were said to have contracted the virus.
During the flight, 15 of the cases displayed symptoms of a fever, with five patients also suffering from respiratory failure and shortness of breath. Thankfully, all of the cases were treated in a timely manner due to the presence of medical staff onboard the repatriation flight.
Upon arrival, all 219 workers were immediately transferred to the National Hospital for Tropical Diseases for medical surveillance and treatment.
