A Nigerian national who arrived in Vietnam from the West African country on Sunday has been isolated so he can be monitored for signs of the deadly Ebola virus after he developed a higher fever, authorities reported.

>> 3 Vietnamese from Ebola-hit Liberia isolated>> Vietnamese couple fined $940 for spreading Ebola rumor >> Vietnam isolates 2 Nigerian visitors from Ebola-hit area The 36-year-old man has been treated in isolation at the Ba Ria Hospital in the southern province of Ba Ria-Vung Tau since Tuesday, said Truong Van Kinh, director of the provincial Health Department. The decision to isolate the Nigerian has been carried out in accordance with a recent regulation by the Ministry of Health to prevent the spread of the Ebola virus, which has killed over 2,500 people in West African countries, including Nigeria, Dr. Kinh said. After receiving treatment, the foreigner’s temperature returned to normal levels, but he needs to be further treated, as he is still suffering from elevated liver enzymes and a low platelet count, doctors said.     He is a contractor working with a Vietnamese oil and gas company in the coastal city of Vung Tau.

After the man, whose name has not been released, was hospitalized, health workers from the provincial Preventive Health Center disinfected his office. His nearby hotel room was also sterilized. The Ho Chi Minh City Pasteur Institute will send specialists to the Ba Ria Hospital to take blood samples from the patient for testing. A week ago, three Vietnamese nationals were also isolated and tested for Ebola after they returned home on a flight from Liberia, another African country that has been serious affected by the deadly virus. They were admitted to the Ho Chi Minh City Tropical Disease Hospital on September 10, after one of them came down with a fever, a symptom of the Ebola virus disease (EVD), health officials said. The group left Liberia for Vietnam on September 8 and arrived at Tan Son Nhat International Airport in HCMC two days later. The ongoing Ebola outbreak has infected 5,000 people in West Africa, more than 2,500 of whom have died, the World Health Organization said on Tuesday. Most of the deaths have occurred Guinea, Liberia and Sierra Leone. Cases have also been reported in Nigeria, where eight people have died, and in Senegal, where a patient is being treated in hospital, WHO said. EVD, which broke out in December 2013 in Guinea, is a severe, often fatal illness, with a fatality rate of up to 90%. The viral infection is transmitted by direct contact with the blood, body fluids or tissues of infected animals or people.
