The deadly Ebola virus is killing more and more people, with the doctor in charge of an Ebola treatment centre in Sierra Leone becoming the latest victim of the deadly virus, the country's health chief said on Tuesday. "Dr Omar Khan died at 2:00 pm," announced the head of Sierra Leone's health services, Brima Kargbo.
Khan was admitted last week into an anti-Ebola treatment facility run by the medical charity Doctors Without Borders (MSF) after testing positive for the virus.
He had been in charge of the main Ebola treatment centre in Kenema, around 320 kilometres (200 miles) east of the capital Freetown. Three nurses at the facility also died of the disease.
Health Minister Miatta Kargbo called Khan a "national hero", praising his "tremendous sacrifice" in working to save the lives of others.
According to the ministry's latest figures released Tuesday, 489 cases of Ebola have been recorded in Sierra Leone and 159 people have died.
Sierra Leone's President Ernest Koroma has this week visited the towns of Kenema and Kailahun to check on the country's response to the epidemic and meet with patients and medical personnel.
Ebola is a form of haemorrhagic fever which is deadly in up to 90 percent of cases.
