Crimean-Congo haemorrhagic fever
Crimean–Congo hemorrhagic fever (CCHF) is a tick-borne viral disease, a zoonosis of domestic animals and wild animals, that may affect humans.
CCHF virus causes severe viral haemorrhagic fever outbreaks, with a case fatality rate of 10–40%.
Symptoms are fever, myalgia, (muscle ache), dizziness, neck pain and stiffness, backache, headache, sore eyes and photophobia (sensitivity to light). There may be nausea, vomiting, diarrhoea, abdominal pain and sore throat early on, followed by sharp mood swings and confusion.
The antiviral drug ribavirin is used to treat CCHF infection.
