ABSTRACT
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.
