Ticks, the members of the superfamily Ixodoidea in the class Arachnida are terrestrial organisms that feed with the blood of mammals, birds, reptiles and amphibians. Infectious organisms being taken by ticks during feeding with host blood pass into the salivary glands, the ovaries, the eggs and the larvae of them. All of the tick-borne viral disease agents are examined within arboviruses. “Heartland virus”, one of these viruses, is transmitted by Amblyomma americanum ticks and can cause multiple organ failure and death. The major vector of “Severe fever with thrombocytopenia syndrome virus” is Haemaphysalis longicornis. “Tick-borne encephalitis virus”, “Powassan virus” and “Louping ill virus” which cause neurological diseases are transmitted to humans by Ixodes spp. “Crimean-Congo hemorrhagic fever virus” which is widespread all over the world is transmitted by Hyalomma spp. Omsk virus affecting the nervous system and “Colorado tick fever virus” affecting hematopoietic cells are carried by Dermacentor spp. All of these viruses are high-level biosecurity agents that constitute individual and social risk. For this reason, it is necessary to be careful while working with clinical specimens. In this review paper, the existing information about the tick-borne viral pathogens mentioned above are presented in the light of current literature.
