Seroprevalence and associated risk factors of co-infection with avian influenza and Newcastle disease in guinea fowls from the Upper East Region of Ghana

The Upper East Region of Ghana, with its diverse poultry farming practices, is particularly vulnerable to outbreaks of infectious diseases such as Avian Influenza (AI) and Newcastle Disease (ND). This study investigated the seroprevalence and risk factors of co-infection with AI and ND in guinea fowls from this region. A total of 397 guinea fowls were sampled, revealing a seroprevalence rate of 24.9% for avian influenza, 50.9% for Newcastle disease, and 12.1% for AI and ND co-infection. No significant associations were found between co-infection rates and variables such as sex, age group, and sampling site. These findings underscore the need for enhanced biosecurity measures, regular surveillance, and further research to manage and prevent AI and ND outbreaks in poultry populations. Enhanced biosecurity, regular monitoring, farmer education, and investigation into additional risk factors are recommended to ensure poultry health and productivity.
