Quick Summary

Crimean-Congo hemorrhagic fever (CCHF) is a severe viral disease characterized by bleeding and fever. It is caused by a virus belonging to the Bunyaviridae family. CCHF is primarily transmitted to humans through the bite of infected ticks, and it also affects cattle and other farm animals.1

The disease is found in parts of Africa, the Middle East, and Russia. While most viral hemorrhagic fevers are geographically limited due to specific animal or insect hosts, CCHF is tick-borne and can be transmitted from animals to humans. Symptoms can include fever, malaise, muscle aches, vomiting, and shock, with bleeding being a prominent characteristic.1

…such as certain rickettsia and Crimean-Congo hemorrhagic fever virus, can even be passed from a female tick to her eggs and subsequent larvae, a phenomenon known as transovarial transmission. Because ticks often feed on multiple host species over their lifetime, they can spread diseases among wildlife, domestic animals, and humans.

…fever virus (genus phlebovirus), and Crimean-Congo hemorrhagic fever virus (genus nairovirus) belong to the family Bunyaviridae. The hantaviruses, like the arenaviruses, are spread to humans by rodent contact. Hantaviruses cause Korean hemorrhagic fever and hantavirus pulmonary syndrome, which is highly fatal because of accumulation of fluid in the lungs but…
