Avian influenza is extremely contagious illness of birds as well as humans. Sera were obtained from a total 400 Desi Chickens or household fowls (Gallus domesticus) from the five districts distinct geographically and analyzed through hemagglutination inhibition (HI) test for detection of antibodies. Maximum sero-prevalence of Avian Influenza (H5N1) was observed in district Tank 78.75% (63/80) followed by Dera Ismail Khan 63.75% (51/80), Peshawar 58.72% (47/80), Abbottabad 52.50% (42/80) and Mansehra 50% (40/80). It was confirmed through statistical analysis that there was a significant (P<0.05) difference of sero-prevalence among these districts. Similarly study also exposed significant (P<0.05) higher seroprevalence of the infection in winter 84% (168/200) and lower in summer 37.5% (75/200). The seroprevalence of the infection was significantly (P<0.05) more severe in sick 76.5% (153/200) than healthy 45% (90/200) desi chickens. Moreover, vaccinated birds 9% (18/200) were significantly at lower risk as compared to non-vaccinated 62.5% (125/200). The chickens kept in close housing system were significant highly prone to the infection 40.38% (86/213) as compared to ones kept in open housing system 30.48% (57/187). The same association was observed in case of biosecuirty (P=0.000), housing zones (P=0.023) and sex (0.000) with the sero-prevalance of infection but non-significant (P=0.500) with rearing systems.
