*OR, odds ratio; AIV, avian influenza virus; –, OR of variable itself is not calculated; boldface indicates that p value is significant.
†Low education indicates junior high school, elementary school, and below; high education indicates senior high school, university or college, and above.
‡ORs are calculated as follows: for different age groups, we calculated 2 ORs—OR1 = odds (<36 y)/odds (36–45 y), OR2 = odds (<36 y)/odds (>45 y); for different education groups, OR = odds (low)/odds (high); for different job groups, OR = odds (chicken keepers)/odds (duck keepers).
