Crimean Hemorrhagic Fever-Congo (CHF-C) Virus Antibodies in Man, and in Domestic and Small Mammals, in Iran

Crimean-Congo Hemorrhagic Fever Virus in High-Risk Population, Turkey

“…Expected seroprevalence of CCHFV among high-risk persons during epidemics has been found to be 10% (3); however, seroprevalence has been reported to be as low as 0.5% in nonepidemic situations (10). Other studies conducted in rural parts of Iran and Senegal during epidemics showed that the CCHFV seroprevalence was 13%, comparable to our fi ndings (9,11).…”

“…However, because special markets for animal trading are located on the outskirts of large cities in Iran, CCHFV seroprevalence was found to be higher among persons living in urban areas than in persons living in rural areas of this country (7). Living in a rural area is a risk factor for exposure to the tick vector and for acquiring CCHFV infection (8,9). Expected seroprevalence of CCHFV among high-risk persons during epidemics has been found to be 10% (3); however, seroprevalence has been reported to be as low as 0.5% in nonepidemic situations (10).…”

Spatial Analysis of Crimean Congo Hemorrhagic Fever in Iran

“…8,9 On the basis of various studies conducted in Iran since 1972, virus circulation has been demonstrated in different regions of Iran. 10,11 The first human clinical cases were confirmed in 1999 in western Iran after a nosocomial infection. 12,13 Since then, the disease has been reported in different parts of Iran and a surveillance system has been planned and conducted.…”

Crimean-Congo hemorrhagic fever in Sistan and Baluchestan Province of Iran, a case-control study on epidemiological characteristics

“…Seropositive rates of sheep and cattle were 38% and 18% respectively. 10 In 1978, during an arbovirological survey conducted in the north-eastern region of Iran, Crimean-Congo hemorrhagic fever virus was isolated, for the first time, from the engorged larvae of Alveonasus lahorensis ticks. 11 Although the most important ways of transmission are known in other parts of the world, patterns of transmission and epidemiological characteristics of this disease are unknown in Iran.…”
