What is Ebola-Sudan Virus Disease?

According to the World Health Organization, "Ebola virus disease (EVD), formerly known as Ebola haemorrhagic fever, is a rare but severe, often fatal illness in humans. The virus is transmitted to people from wild animals and spreads in the human population through human-to-human transmission."

According to the International Classification of Disease for filoviruses (ICD-11) released in May 2019, "Ebola disease is now sub-categorized depending on the causative virus. Outbreaks of Ebola disease caused by Sudan virus are named Sudan Virus Disease (SVD) outbreaks. Prior to May 2019 all viruses causing Ebola disease were grouped together. Based on the results of laboratory tests, this outbreak is caused by Sudan virus.

Sudan virus disease is a severe, often fatal illness affecting humans. Sudan virus was first reported in southern Sudan in June 1976, since then the virus has emerged periodically and up to now, seven outbreaks caused by SUDV have been reported, four in Uganda and three in Sudan. The estimated case fatality ratios of SVD have varied from 41% to 100% in past outbreaks."
