Crimean-Congo hemorrhagic fever (CCHF), which is transmitted by tick bites and can be fatal, killed a woman in Çankırı's Ilgaz district on Tuesday.
Cemile Tiryaki, 70, was first taken to the Ilgaz State Hospital after she was bitten by a tick and then transferred to the Ankara Research and Training Hospital with a suspected case of CCHF, where she subsequently died.
Three individuals from Kastamonu, a shepherd from Tokat and a farmer from Çorum also died of CCHF last week. There is no vaccine against the disease, which causes hemorrhaging, high fever, muscle pain and vomiting and which has a mortality rate of about 30 percent. The disease is mainly contracted by farm and slaughterhouse workers in the countryside in Central Anatolia and the Black Sea region.
