Crimean- Congo Haemorrhagic Fever is an Arboviral Zoonotic infection which several cases of that have been reported in Iran. Measurement of antibody level of Crimean-Congo Haemorrhagic Fever among local and imported sheep's in Isfahan province and presence of tick on their body are the main purposes of this study. This cross sectional study has been performed among 372 local and the same amount of imported sheep's, regarding to the presence of IgG antibody of Crimean-Congo Haemorrhagic Fever and tick on their body. The study was made with the special helps of Arbovirus laboratory of Iranian Pasteur Institute on 2002. 286 (76.9%) of local and 223 (57.8%) of imported sheep's have had seropositive results but these data were statistically meaningless (P = 0.094). Ticks have been found on the body surface of 115 (31%) of local sheep's but among imported one's were totally absent. The results of this study revealed the endemic spreading of CCHF in the sheep's in Isfahan province and it needs special attention to prevent the infection in the communities and occupational exposure.
