This study was conducted to evaluate if such infection existence in workers of slaughter house and patients in Abhar hospital.This study, was conducted in Abhar poultry houses and Abhar hospital. Two hundred samples from poultry, 100 samples from patients with non-respiratory signs, 75 samples from patients with respiratory signs and 25 samples from poultry slaughterhouse workers was taken. To prevent false positive and negative results in HI test the sera were treated by trypsin-periodate and concentrated RBC respectively, and then serums was tittered by HI test.Our results indicated 80 percent of poultry flocks, 44 percent of poultry slaughterhouse workers was positive in HI test against H9N2 influenza. The high percentage of positive cases and higher titers in slaughterhouse workers indicate that the infectivity of the virus requires close contact with birds or their droppings.
