ANAYA VELARDE, Luis  and  DURAN ARENAS, Luis. Status Ebola outbreak in West Africa in 2014. Rev. Fac. Med. (Méx.) [online]. 2014, vol.57, n.6, pp.11-16. ISSN 2448-4865.

Since the onset of the outbreak im December 2013 and up to the September 20 cut-off, there have been 2,909 deaths in the 6,185 likely cases of Ebola. It is considered that the letality under 50%, considerably lower tan the one reported in previous outbreaks of the disease, is biased due to the dificulty to collect and analyze information. On September 23, WHO showed a review of such estimations, indicating 70% letality.

The outbreak was originally reported in Liberia and Guinea. Further cases were reported in Nigeria, Sierra Leone, and Senegal. All the cases confirmed by laboratory have been EBOV positive. The initial source of the outbreak was found in the village called Meliandou in the in Guéckédou Prefecture, Guinea. The index case was a two-year-old boy, who die don December 6, 2013. His mother, sister and grandmother also died because of the disease. The people from this village transmitted the disease to people in nera-by villages. The outbreak initially spread to Liberia and then to Sierra Leone. Virus circulation continues in three countries. The transmision of some cases to Nigeria and Senegal led these countries to close their borders to the three formerly mentioned countries and quarantine suspicious individuals. So far, neither country has presented new cases; hence they are considered under control. Likewise, cases imported from those countries into the United States, France, Germany, spain, Switzerland, and the Uited Kingdom have been reported.
