Background: The Crimean-Congo hemorrhagic fever virus (CCHFV) presents a wide distribution, with the Balkan Peninsula being among the endemic regions. To date, only one CCHF case has been reported in Greece; however, based on seroprevalence data, there is evidence that CCHFV circulates in the country. Achaia is a prefecture in western Greece that has not previously been studied for CCHFV.
Objectives: The aim of this study was to estimate the seroprevalence of CCHFV in humans in Achaia Prefecture, Greece, and to assess possible factors playing a role in seropositivity.
Methods: A total of 207 serum samples from people of all age groups, from both urban and rural areas, were prospectively collected and tested for IgG antibodies against CCHFV.
Results: The overall seroprevalence was 3.4%, with significant differences among municipalities. An agro-pastoral occupation, contact with sheep and goats, former tick bite, increasing age, and living at an altitude of ≥400 m, on specific land cover types, were significantly associated with CCHFV seropositivity.
Conclusions: A relatively high seroprevalence was detected in a previously unstudied region of Greece, where CCHFV infection seems to occur mainly through tick bites. Further investigations are needed to identify the circulating CCHFV strains in Greece, in order to gain a better understanding of CCHFV ecology and epidemiology in the country.

Objectives: Arboviruses pose a significant global health challenge. This study investigated the seroprevalence of major human arboviral infections, including yellow fever (YFV), dengue (DENV), Crimean-Congo hemorrhagic fever (CCHF), Rift Valley fever (RVF), West Nile virus (WNV), and chikungunya (CHIK), in Darfur region from September to December 2018. ELISA-IgM was used to detect antibodies.

Crimean-Congo hemorrhagic fever (CCHF) is a zoonotic infectious disease caused by the CCHF virus, a member of the Bunyavirales order and the Orthonairoviridae family. The exact pathogenesis is not fully understood. Long noncoding RNAs (lncRNAs) are RNAs that are shown to play a role in various pathological processes of viral diseases.

Most members of the genus Orthonairovirus, represented by Crimean-Congo hemorrhagic fever virus and Nairobi sheep disease virus, are tick-borne, and some have become a public health concern in recent years. Here, we report the isolation and genetic and biological characterization of a new orthonairovirus, designated as "Iwanai Valley virus" (IWVV), from Ixodes ovatus ticks in Hokkaido, Japan. The amino acid sequence of the viral nucleoprotein (NP) was found to be 34-45% identical to those of known orthonairoviruses.

Spread by Hyalomma genus ticks, Crimean-Congo hemorrhagic fever virus (CCHFV) causes a severe hemorrhagic disease endemic throughout Southern and Eastern Europe, Asia, and Africa. To date, there are no widely approved vaccines for CCHFV and treatment for disease is largely supportive. Due to this lack of intervention, the WHO lists CCHFV as a high-priority pathogen.

Crimean-Congo hemorrhagic fever virus (CCHFV) is a tickborne virus that can cause severe disease in humans with case fatality rates of 10%-40%. Although structures of CCHFV glycoproteins GP38 and Gc have provided insights into viral entry and defined epitopes of neutralizing and protective antibodies, the structure of glycoprotein Gn and its interactions with GP38 and Gc have remained elusive. Here, we use structure-guided protein engineering to produce a stabilized GP38-Gn-Gc heterotrimeric glycoprotein complex (GP38-Gn-Gc).
