| Abstract: | Infectious bronchitis virus (IBV) remains a major respiratory pathogen of economic concern in the poultry industry. This study investigated the farm-level prevalence of IBV and evaluated associated risk factors in northern Vietnam by a cross-sectional study from June 2022 to June 2024. A total of 69 poultry farms were randomly selected across nine provinces, and pooled tracheal swab samples were purposively collected for IBV detection using RT-qPCR. The overall IBV farm-level prevalence was 34.78 % (95 % CI:23.71-47.21 %). Although no statistically significant differences were found across provinces, production types, age groups, or flock sizes, IBV was detected in all subgroups, indicating widespread circulation of the virus. A total of 22 potential risk factors were initially assessed using univariate logistic regression. Of these, six variables with P |
