These states represent the part of the country where there has been no reports of clinical disease or antibody to Orungo virus. Orungo virus antibodies were detected in 26.7% of the sheep, 6.8% of the cattle, 30.7% of the goats and 37.5% of the camels tested by the complement fixation method. The antibody titer in the various positive samples were also determined. Hitherto, Orungo virus infection has not been reported in goats and camels in this country.
