Ebola Virus Disease outbreak has kills 670 people in West African countries including Liberia and Sierra Leone where the virus has killed most of the people. A doctor who caught the infection while treating the Ebola patients in Sierra Leone has also died.
The government said Dr. Sheik Humarr Khan’s death was “an irreparable loss of this son of the soil”. The 39-year-old was a leading doctor on hemorrhagic fevers in a nation with very few medical resources.
Ebola cases first emerged in the nation of Guinea back in March, and later spread across the borders to Liberia and Sierra Leone. The outbreak is now the largest recorded in world history, and has infected three African capitals with international airports. Officials are trying to step up screening of passengers, though an American man was able to fly from Liberia to Nigeria, where authorities say he died days later from Ebola.
Ebola has no vaccine and no specific treatment, with a fatality rate of about 60 per cent. But experts say the risk of travelers contracting it is considered low because it requires direct contact with bodily fluids or secretions such as urine, blood, sweat or saliva. Ebola can’t be spread like flu through casual contact or breathing in the same air.
Patients are contagious only once the disease has progressed to the point they show symptoms, according to the World Health Organization. The most vulnerable are health care workers and relatives who come in much closer contact with the sick.
The President of Sierra Leone has declared a public health emergency as the Ebola crisis deepens across West Africa.
The announcement from President Ernest Bai Koroma late on Wednesday came as neighbouring Liberia also ramped up efforts to slow the virulent disease’s spread.
The U.S. Peace Corps also was evacuating hundreds of its volunteers in the affected countries. Two Peace Corps workers are under isolation outside the U.S. after having contact with a person who later died of the Ebola virus, a State Department official said.
What is Ebola Virus Disease
- Ebola virus disease (EVD), formerly known as Ebola haemorrhagic fever, is a severe, often fatal illness in humans.
- EVD outbreaks have a case fatality rate of up to 90%.
- EVD outbreaks occur primarily in remote villages in Central and West Africa, near tropical rainforests.
- The virus is transmitted to people from wild animals and spreads in the human population through human-to-human transmission.
- Fruit bats of the Pteropodidae family are considered to be the natural host of the Ebola virus.
- Severely ill patients require intensive supportive care. No licensed specific treatment or vaccine is available for use in people or animals.
