- In Greece, one single CCHF case has been reported, in 2008; since the CCHFV seroprevalence in humans in specific regions of the country is high (>5%), it has been suggested that it may be related with a non- or low-pathogenic strain causing asymptomatic infections.

Mar 16, 2021 · Vertebrates—humans are an exception—are asymptomatic during a CCHF infection but maintain a short period of viremia lasting less than 14 days . This short window of infection is sufficient for viral propagation but poses significant challenges to monitoring active CCHF infections in livestock and other sentinel animal populations.

Mar 21, 2021 · The clinical course of the infection varies from asymptomatic to severe and even fatal cases (3–40%) [5,6]. In fact, asymptomatic infections seem common [ 7 ], reaching up to 90% cases in some studies from hyperendemic areas [ 8 ].

Mar 21, 2006 · Crimean-Congo haemorrhagic fever (CCHF) is an often fatal viral infection described in about 30 countries, and it has the most extensive geographic distribution of the medically important tickborne viral diseases, closely approximating the known global distribution of Hyalomma spp ticks.

Aug 5, 2016 · In the absence of human cases, it has been suggested that a non- or low-pathogenic strain is circulating in the country causing asymptomatic infections. A spatial cluster analysis was performed to assess the geographical variations in CCHFV seropositivity and to identify the risk factors.
Sep 1, 2020 · CCHFV infection in immunocompetent adult mice is generally asymptomatic, making it mandatory to develop adequate experimental models for CCHF pathogenesis [150]. In 1990, Morrill et al. asserted that a slow interferon response was related to a higher mortality in Rift Valley fever [ 151 ].
