Avian influenza viruses (AIVs) can cause economically devastating diseases in poultry production and have the potential for zoonotic transmission. The ecology of the virus is affected by numerous natural and social factors. The purposes of this study were to identify the relationship between the prevalence rate of avian influenza A in the live bird markets in suburban districts of Ha Noi and climate, social factors. The studied results showed that the average AIV positive sample rate was 18.85%, AIV (non-H5) was 15.95%, H5 was 2.92%, N1 was 0.4%, and N6 was 0.1%. January, March, April, and August had a higher percentage of positive samples for AIV and AIV H5 compared to other months. Among the duck, chicken, and environmental samples, the duck samples had the highest positive detection rates of influenza A, H5, and N6. The temperature and sunshine duration factors were closely related to the AIV positive sample detection rate and the humidity and sunshine duration factors were closely related to the AIV H5 positive sample detection rate.Virus cúm gia cầm là nguyên nhân tàn phá kinh tế trong chăn nuôi gia cầm và có khả năng lây truyền từ động vật sang người.
