Crimean-Congo hemorrhagic fever (CCHF) is a tick-borne viral disease mainly affecting pastoralists who come in contact with animals infested with Hyalomma ticks, which are the key vectors of CCHF virus (CCHFV). CCHFV has been detected among these ticks in parts of North Eastern Kenya. This study aimed to identify acute cases of CCHF, and to determine the extent of previous exposure to CCHFV in ...

Background and Aims: Crimean-Congo hemorrhagic fever (CCHF) is a fatal viral disease that occurs in approximately 30 countries. It has the most extensive geographic range among the tick-borne viruses that affect human health. CCHF viruses have a tripartite RNA genome consisting of large (L), medium (M) and small (S) segments. This study was undertaken to determine the genetic relationship of CC...

The widespread geographical distribution of Crimean-Congo hemorrhagic fever (CCHF) virus (more than 30 countries) and its ability to produce severe human disease with high mortality rates (up to 60%) make CCHF a major public health concern worldwide. We describe here the successful establishment of a reverse genetics technology for CCHF virus, a member of the genus Nairovirus, family BUNYAVIRID...

In January 2016, a migrant worker who returned home to India after becoming ill in Oman was confirmed to have Crimean-Congo hemorrhagic fever (CCHF). Physicians should include CCHF in the differential diagnosis for patients with hemorrhagic signs and a history of recent travel to any area where CCHF is endemic or prevalent.

The aim of this study was to determine the knowledge levels of students in the Midwifery and Nursing Departments of the School of Health Sciences in Kahramanmaras Sutcuimam University (KSU) about Crimean-Congo hemorrhagic fever (CCHF) and to examine the factors influencing those knowledge levels. The study was conducted between April-June 2009 in the School of Health Sciences, KSU, Turkey. All ...

During the last decade Crimean-Congo hemorrhagic fever (CCHF) emerged and/or re-emerged in several Balkan countries, Turkey, southwestern regions of the Russian Federation, and the Ukraine, with considerable high fatality rates. Reasons for re-emergence of CCHF include climate and anthropogenic factors such as changes in land use, agricultural practices or hunting activities, movement of livest...

Introduction CCHF foci are reported in 3 southern regions of Kazakhstan with population of 1 million. The ixodic ticks in the area are CCHF carriers. Human infections (3 to 12 cases per year) occur through tick bites and contact with CCHF patient blood. CCHF epidemiological process in Kazakhstan has prominent seasonality (spring-summer period) and the rhythm of epidemic appearances (5-6-years)....

Genetic analysis of wild-type Crimean-Congo hemorrhagic fever (CCHF) virus strains recovered in the European part of Russia was performed. Reverse transcriptase PCR followed by direct sequencing was used to recover partial sequences of the CCHF virus medium (M) genome segment (M segment) from four pools of Hyalomma marginatum ticks and six human patients. Phylogenetic analysis of the M-segment ...
