Analysis of data generated
Descriptive analysis was performed using the questionnaire data from the
first phase, to describe the populations and pertinent husbandry and
management practices. The data generated were used to perform Social
Network Analysis (SNA). Contact networks were defined for each
enterprise type on the basis of information provided by the respondents
on poultry movements between enterprises. Centrality scores examined
included in-degree, out-degree and betweenness. The properties of each
network were assessed.
The results of sample testing were analysed descriptively to show
differences between the enterprise types and the sampling rounds.
Hypothesis tests (Fisher’s Exact test) were done to investigate whether
the differences between the proportions of positive H5 test results
differed between the enterprise types. The results of the testing for H9
AIV were investigated to provide information on presence, persistence
and co-circulation with H5 virus.
