Abstract
Viral hemorrhagic fevers (VHFs) represent a collection of illnesses caused by several distinct viral families. While some types of hemorrhagic fever viruses can cause relatively mild illnesses, many of these viruses cause life-threatening diseases.
In general, the term ""viral hemorrhagic fever""describes a severe multisystem syndrome. Typical for this syndrome is a systemic damage of vascular system often accompanied by hemorrhages.
Nevertheless the bleeding itself is rarely life-threatening. In the autumn and winter of 2014 every day professional and popular press published new information about Ebola outbreak in West Africa.
It was not just data related to the number of patients, new recommendations and protocols, information about testing of potential vaccines, but also theoretical works that tried to analyze the situation and data. Authors were trying to answer questions why Ebola virus emerged again in West Africa, and what it meant for the future.
