This study investigates avian viral infections, with a particular focus on Newcastle disease, across several farms in Algeria. A statistical model is proposed to address and characterize this phenomenon. A multiple-choice questionnaire was designed to gather information from 60 practicing veterinarians via Drag'n Survey. Out of forty questions, six were selected to assess the understanding, management, treatment efficacy, and prevention of Newcastle disease in the poultry industry. The results from this questionnaire provided valuable insights and met the study's objectives. Observations from veterinary practitioners indicated a 65.84% prevalence of Newcastle disease in broilers, with a subsequent rate of over 15% in laying hens, 11.53% in future laying hens, and 7.69% in broiler breeders. Our findings revealed an overall prevalence of 38.91% for Newcastle disease, with infectious bronchitis following at an average prevalence rate of 32%. Gumboro disease had a prevalence of 20%, and weak avian influenza was reported with a frequency of 12%. Infectious laryngotracheitis was the least common, with an average prevalence rate of 4%.
