Crimean-Congo hemorrhagic fever


Crimean-Congo hemorrhagic fever (CCHF) is a widespread disease caused by a tick-borne virus. The CCHF virus causes severe viral hemorrhagic fever outbreaks, with a case fatality rate of 10–40%. It is endemic in Africa, the Balkans, the Middle East and Asian countries.

Animals like sheep, goats and cows 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.

Onset of symptoms is sudden, with fever, myalgia, (muscle ache), dizziness, neck pain and stiffness, backache, headache, sore eyes and photophobia (sensitivity to light). There may be nausea, vomiting, diarrhea, abdominal pain and sore throat early on, followed by sharp mood swings and confusion.

General supportive care with treatment of symptoms is the main approach to managing CCHF in people. The antiviral drug ribavirin has been used to treat CCHF infection with apparent benefit.
