| crimean-congo hemorrhagic fever in sistan and baluchestan province of iran, a case-control study on epidemiological characteristics. | several cases of crimean-congo hemorrhagic fever (cchf), an arboviral disease, have been reported since summer 1999 in different areas of iran. the main objectives of this research were to determine the most important means and patterns of transmission and the epidemiologic characteristics of this disease. | 2004 | 15325599 |
| seroprevalence of crimean-congo hemorrhagic fever in sistan-va-baluchestan province of iran. | during the years 2000 to 2004, of 248 serologically confirmed cases of crimean-congo hemorrhagic fever (cchf) that occurred in several parts of iran, 169 were reported from sistan-va-baluchestan province. to assess the seroprevalence of cchf virus infection within the zahedan and zabol districts of the sistan-va-baluchestan province in iran, 300 subjects were sampled from the general population. in addition to blood sampling, a questionnaire was completed for every subject. all but just 3 of our ... | 2006 | 17060701 |
| knowledge and attitude toward crimean-congo haemorrhagic fever in occupationally at-risk iranian healthcare workers. | we assessed the knowledge and attitude (k&a) toward crimean-congo haemorrhagic fever (cchf) of occupationally at-risk healthcare workers (hcws). a cross-sectional survey was performed in three referral hospitals in the systan-baluchestan and isfahan provinces of iran where cchf is highly endemic. in all, 191/209 eligible hcws were enrolled (response rate: 93%). all but 11 (5.8%) had heard of cchf. the mean k&a scores of the respondents were 50.34% and 79.25%, respectively. the correlation betwee ... | 2008 | 18395295 |
| the risk of transmission of crimean-congo hemorrhagic fever virus from human cases to first-degree relatives. | to determine the infectivity of crimean-congo hemorrhagic fever (cchf) virus via routine contacts between serologically confirmed cases and their close relatives from may 2005 up to march 2006, 79 serum samples of 57 close relatives of 12 newly diagnosed serologically confirmed cchf cases in the sistan-va-baluchestan province of iran were tested for igg and igm antibodies against cchf virus using the enzyme-linked immunosorbent assay technique. nine levels of contacts were considered: percutaneo ... | 2008 | 19050365 |
| crimean-congo hemorrhagic fever in iran. | the presence of crimean-congo hemorrhagic fever virus (cchfv) in iran was first identified in studies of livestock sera and ticks in the 1970s, but the first human infection was not diagnosed until 1999. since that time, the number of cases of cchf in iran has markedly increased. through january 2012, articles in the published literature have reported a total of 870 confirmed cases, with 126 deaths, for a case fatality rate (cfr) of 17.6%. the disease has been seen in 26 of the country's 31 prov ... | 2013 | 23872313 |
| crimean-congo hemorrhagic fever among health care workers in iran: a seroprevalence study in two endemic regions. | crimean-congo hemorrhagic fever (cchf) has repeatedly caused nosocomial outbreaks among hospital staff. in the summer of 2003, we studied the seroprevalence of anti-cchf igg among health care workers who had come in contact with crimean-congo hemorrhagic fever patients from three referral hospitals in endemic regions of iran. a total of 223 eligible staff were examined. whereas 5 of 129 (3.87%) exposed health care workers tested positive, none of the 94 in the unexposed group did (p=0.075). sero ... | 2007 | 17360865 |
| evaluation of the efficacy of ribavirin therapy on survival of crimean-congo hemorrhagic fever patients: a case-control study. | the mortality rate resulting from crimean-congo hemorrhagic fever (cchf) has been reported in different epidemics to range from 5% to more than 70%. while ribavirin has been recommended as the drug of choice in the treatment of cchf, no consistent study has unequivocally demonstrated its effectiveness. using the case-control method, we attempted to evaluate the efficacy of ribavirin in reducing mortality among cchf cases admitted to boo-ali educational hospital in zahedan, iran, during the years ... | 2009 | 19168952 |
