Tick-borne viruses (TBVs) belong to the Flaviviridae, Bunyaviridae, Reoviridae, Asfarviridae and Orthomyxoviridae families and cause different diseases in humans and animals. Due to the epidemiologic relevance of TBVs, this review highlights the actual knowledge of these agents and the diseases they cause, besides of the prevention and treatment strategies implemented so far. It is evident that studies that address the TBVs present in the Neotropical region are missing, since most of the studies, both reviews and original articles, present data from the Nearctic and Palearctic regions. Considering the current picture of the TBVs studies in the Neotropical area and its peculiarities, is probable that other not yet identified TBVs exist in this zone and have an impact in public health.
