conclusions this study showed that this novel one-step rrt-pcr assay is a rapid, reliable, repeatable, specific, sensitive, and simple tool for the detection of the cchf virus. results from a total of 75 suspected serum samples, 42 were confirmed to be positive for cchf virus, with no false-positives detected by the sequencing results. after 40 amplification cycles, the melting curve analysis r...

conclusions the viral load in patients who suffer from cchf has a direct significant correlation with disease severity. viral load above 8.6 × 105 copies/ml on the first day of admission is a predictor of severe cchf. background crimean-congo hemorrhagic fever (cchf) is an endemic disease in south eastern of iran, especially in sistan and baluchestan province. cchf is a potentially fatal diseas...

The spatial pattern in Senegal of Crimean-Congo hemorrhagic fever (CCHF) virus IgG antibody prevalence in human and sheep was determined as was the relative abundance of potential tick vectors. A systematic, country-wide serological survey of sheep demonstrated that 10.4% of sheep exhibited IgG to CCHF virus. Sexes were infected equally. Antibody prevalence increased with age from 2.1% during t...

We report the genetic characterization of the M RNA segment of Crimean Congo hemorrhagic fever virus (CCHFV). Two CCHFV strains isolated in Xinjiang Province, a region endemic for CCHF in northwestern China, were studied. These strains, designated BA66019 and BA8402, were isolated in 1965 and 1984 from a CCHF patient and Hyalomma ticks, respectively. Viral RNA was extracted from suckling mouse ...

Crimean-Congo hemorrhagic fever (CCHF) is a widely distributed, tick-borne viral disease. Humans are the only species known to develop illness after CCHF virus (CCHFV) infection, characterized by a nonspecific febrile illness that can progress to severe, often fatal, hemorrhagic disease. A variety of animals may serve as asymptomatic reservoirs of CCHFV in an endemic cycle of transmission. Sero...

The objective of this study was to investigate the relationship between serum total thiol level and total oxidant status (TOS) and thrombocytopenia among patients with Crimean-Congo hemorrhagic fever (CCHF). Eighty-three subjects and 56 controls were enrolled in the study. Thiol levels were measured with the DTNB method and TOS was measured with the Erel's method among subjects and controls. Th...

Crimean-Congo Hemorrhagic Fever is a fatal viral disease that occurs in some parts of Africa, Asia, Eastern Europe and the Middle-East. Primarily it is a zoonosis but can be seen sporadically in humans. Recently outbreaks have been reported from Pakistan, Afghanistan, Saudi Arabia, United Arab Emirates and Iran. In this retrospective study, we evaluated the efficacy of oral Ribavirin in the...

From February to August 2003, 38 persons were infected with Crimean-Congo hemorrhagic fever (CCHF) virus in Mauritania; 35 of these persons were residents of Nouakchott. The first patient was a young woman who became ill shortly after butchering a goat. She transmitted the infection to 15 persons in the hospital where she was admitted and four members of her family. In Nouakchott, two disease c...
