Global Alert and Response (GAR)  Crimean-Congo haemorrhagic
fever (CCHF)  Tick of genus Hyalomma  Crimean-Congo Hemorrhagic

be responsible for severe outbreaks in humans but it is not
pathogenic for ruminants, their amplifying host.  The disease
was first described in the Crimea in 1944 and given the name
Crimean haemorrhagic fever. In 1969 it was recognized that the
pathogen causing Crimean haemorrhagic fever was the same as that
responsible for an illness identified in 1956 in the Congo, and
linkage of the two place names resulted in the current name for
the disease and the virus.  CCHF spreads to humans either by
tick-bites, or through contact with viraemic animal tissues
during and immediately post-slaughter. CCHF outbreaks constitute
a threat to public health services because of its epidemic
potential, its high case fatality ratio (10-40%), its potential
for nosocomial outbreaks and the difficulties in treatment and
prevention. CCHF is ende
