Iran reports dozens of Crimean-Congo hemorrhagic fever cases


According to a report in the Tehran-based, Iran Front Page, 60 people have tested positive for Crimean-Congo hemorrhagic fever (CCHF), including three deaths.

Crimean-Congo hemorrhagic fever is a widespread disease caused by a tick-borne virus (Nairovirus) of the Bunyaviridae family. The CCHF virus causes severe viral hemorrhagic fever outbreaks, with a case fatality rate of 10–40%.

Animals become infected by the bite of infected ticks and the virus remains in their bloodstream for about one week after infection, allowing the tick-animal-tick cycle to continue when another tick bites. Although a number of tick genera are capable of becoming infected with CCHF virus, ticks of the genus Hyalomma are the principal vector.
