In each village, we used a 24-question survey to assess
study participants’ poultry rearing practices, how animals
were housed, whether and what kind of protective
measures were taken against H5N1 and other diseases,
as well as human demographic information such as the
number of people per household. At least 15 inhabitants
were surveyed at each site (mean = 19, Table 1). The survey
also contained questions that the interviewer observed
and recorded privately, such as whether poultry were kept
in a closed building or fenced-in area. Efforts were made to
obtain interviews from the same households in which
poultry were sampled, however poultry were observed to
be free-ranging and in many cases flocks from different
households mixed freely.
