Ebola
The deadly epidemic broke out in West Africa in 2013 and lasted for about three years. The virus disease killed over 11,300 people, largely in Liberia, Sierra Leone, and Guinea. A severe, often fatal illness in humans, Ebola is often transmitted from animals to people, and then from people to people by direct contact with infected blood, bodily fluids or organs, or indirectly through contact with contaminated areas. Claiming lots of lives and leading to major socioeconomic losses between 2013 and 2016, Ebola re-emerged in August 2018 in the eastern Democratic Republic of Congo. It has so far killed more than 2,200.
