BACKGROUND Mice lacking the type I interferon receptor (IFNAR-/- mice) reproduce relevant aspects of Crimean-Congo hemorrhagic fever (CCHF) in humans, including liver damage. We aimed at characterizing the liver pathology in CCHF virus-infected IFNAR-/- mice by immunohistochemistry and employed the model to evaluate the antiviral efficacy of ribavirin, arbidol, and T-705 against CCHF virus. M...

BACKGROUND Ticks are important vectors and reservoirs of Crimean Congo Hemorrhagic Fever (CCHF) virus. Human beings may be infected whenever the normal life cycle of the infected ticks on non-human vertebrate hosts is interrupted by the undesirable presence of humans in the cycle. A total of 26 species of Argasid and Ixodid ticks have been recorded in Iran; including nine Hyalomma, two Rhipicep...

BACKGROUND The Crimean-Congo hemorrhagic fever (CCHF) virus causes severe disease in humans, with a high mortality rate. Since, there is no approved vaccine or specific treatment for CCHF, an early and accurate diagnosis, as well as reliable surveillance, is essential for case management and patient improvement. OBJECTIVES For this research, our aim was to evaluate the application of a novel ...

BACKGROUND Crimean-Congo hemorrhagic fever (CCHF) is a potentially fatal disease caused by a tick-borne virus from the Bunyaviridae family. It has recently been reported that soluble urokinase-type plasminogen activator receptor (suPAR), secreted from endothelial cells and the mononuclear phagocyte system, one of the main targets of the CCHF virus, is a potential biomarker for several bacterial...

Background Crimean-Congo Hemorrhagic Fever (CCHF) is a viral zoonotic disease with high mortality rate in humans caused by CCHF virus (CCHFV) belonging to the genus Nairovirus, family Bunyaviridae, and congaing a three segment single-stranded RNA genome. The CCHFV is transmitted to humans by bite of infected ticks, by direct contact with blood or tissues of infected livestock and nosocomially. ...

To determine the infectivity of Crimean-Congo hemorrhagic fever (CCHF) virus via routine contacts between serologically confirmed cases and their close relatives from May 2005 up to March 2006, 79 serum samples of 57 close relatives of 12 newly diagnosed serologically confirmed CCHF cases in the Sistan-va-Baluchestan province of Iran were tested for IgG and IgM antibodies against CCHF virus usi...

During January-September 2014, Georgia's National Centers for Disease Control and Public Health (NCDC) detected 22 cases of Crimean-Congo hemorrhagic fever (CCHF) in the country. CCHF is caused by infection with a tickborne virus of the Bunyaviridae family. Transmission occurs from the bite of an infected tick or from crushing an infected tick with bare skin. Secondary transmission can result f...

Healthcare-related transmission of Crimean-Congo haemorrhagic fever (CCHF) is a well-recognized hazard. We report a multicentre retrospective cross-sectional study undertaken in Turkey in 2014 in nine hospitals, regional reference centres for CCHF, covering the years 2002 to 2014 inclusive. Data were systematically extracted from charts of all personnel with a reported health care injury/accide...

Crimean-Congo hemorrhagic fever virus (CCHFV) is a viral hemorrhagic fever of the Nairovirus group that belongs to the Bunyaviridae family. Crimean-Congo hemorrhagic fever (CCHF) is a severe infectious disease with a mortality rate as high as 5%, and it is characterized by fever and bleeding. CCHF first emerged in Turkey in 2002, and the prevalence of the disease has been found to be increased ...

Crimean-Congo Haemorrhagic Fever (CCHF) is a severe tick-borne disease, endemic in many countries in Africa, the Middle East, Eastern Europe and Asia. Between 15-70% of reported cases are fatal. There is no approved vaccine available, and preclinical protection in vivo by an experimental vaccine has not been demonstrated previously. In the present study, the attenuated poxvirus vector, Modified...
