Crimean-Congo haemorrhagic fever (CCHF) is one of the most widespread arboviroses in the world. It is present in Africa, south-east Europe, the Middle East and Asia. It is caused by a nairovirus (Bunyaviridae family) transmitted by several species of ticks. The geographical distribution of the disease coincides with the distribution of Hyalomma ticks. While infected livestock do not show signs ...

Crimean-Congo hemorrhagic fever (CCHF) is a tick-borne disease caused by the arbovirus Crimean-Congo hemorrhagic fever virus (CCHFV), which is a member of the Nairovirus genus (family Bunyaviridae). CCHF was first recognized during a large outbreak among agricultural workers in the mid-1940s in the Crimean peninsula. The disease now occurs sporadically throughout much of Africa, Asia, and Europ...

C rimean-Congo haemorrhagic fever (CCHF) is a zoonotic, vector-borne disease caused by a virus in the Bunyaviridae family, of the genus Nairovirus. This disease affects humans and animals very differently. In humans, CCHF can vary from asymptomatic infection to severe haemorrhagic fever, with death occurring in up to 30% of severely ill patients. Many other species of mammals and some birds can...

background crimean-congo hemorrhagic fever (cchf) was a rare disease in iran before 1999. during the last 15 years, it has been reported from different provinces of iran, mostly from southeastern iran. objectives this study aimed to evaluate the factors associated with poor outcome in children and adolescents with cchf. patients and methods we studied all files of children (age < 19 years old) ...

conclusion we recommend that in outbreaks of cchf, care to prevent airborne transmission should be kept in mind. patient and method by a nosocomial transmission of crimean-congo hemorrhagic fever (cchf), a health care worker was infected in december 2008 due to a re-emerging outbreak of cchf in fars province, iran. after admission of probable cchf cases in a local hospital, one of the nurses co...

background: crimean-congo hemorrhagic fever virus (cchfv) belongs to genus nairovirus and family bunyaviridae. the main aim of this study was to investigate the extent of recombination in s-segment genome of cchfv in iran. methods: samples were isolated from iranian patients and those available in genbank, and analyzed by phyloge­netic and bootscan methods. results: through comparison of the ph...

introduction : this study was aimed to investigate the effects of risk factors, and environmental and climatic factors a ffecting the occurrence of crimean-congo hemorrhagic fever (cchf) in iran. we used temporal modeling to predict the future occurrence of the disease in the country . methods : we analyzed the data of 165 cchf patients from all over iran (e xcept the districts zabol and zaheda...

background: crimean congo hemorrhagic fever (cchf) is an acute febrile haemorrhagic disease. this study was conducted to ascertain the infection status amongst slaughterhouse workers in iran's north-eastern provinces (razavi and northern and southern khorasan), so that analysis of the results could help clarification of the epidemiology of this disease in the aforementioned provinces and easter...

background: the world health organization (who) declares crimean congo hemorrhagic fe­ver (cchf) endemic in turkey. despite the magnitude of problem, no documented evi­dence exists in turkey, which reveals the aware­ness and practices of the country's adult popula­tion regarding cchf, its spread, symptoms, treatment, and preven­tion. this study was conducted to assess the level of knowledge, at...
