Statistical Analysis of Ebola Virus Disease outbreak in Some West Africa Countries using S-I-R Model

Abstract

Ebola virus in particular is deadly, poorly understood, and capable of causing a large-scale threat to Public Health. Ebola Virus Diseases which is also known as Ebola hemorrhagic fever, (or EHF), is a viral hemorrhagic fever of humans and other primates caused by Ebola viruses [1]. Ebola is a rare and deadly disease caused by infection with one of the Ebola virus species. According to the WHO [2], Ebola is caused by infection with a virus of the family Filoviridae. The disease, which the World Health Organisation declared an outbreak on 23rd March 2014, first occurred in Yambuku, Democratic Republic of Congo and surrounding areas in 1976. The disease was spread close personal contact and by use of contaminated needles and syringes in hospitals/clinics [3]. This outbreak was the first recognition of the disease. Since then, there have been many outbreaks with the latest in Guinea, Liberia and Sierra Leone. Now the Ebola Virus Disease which began in December 2013 and killed a two-year-old boy in Guinea, was the beginning of an outbreak in that year and killed over 5000 people in a year, leaving hundreds of children orphaned and affecting thousands more [3].
