Assessment on Exposure to Highly Pathogenic Avian Influenza A(H5N1) and Poultry Trading Practices among Poultry Traders in Traditional Markets of Sukoharjo District, Central Java Province, Indonesia, 2012

Abstract

Sukoharjo District has been an endemic area of highly pathogenic avian influenza (HPAI) subtype A(H5N1). We conducted a serology investigation to determine the level of human exposure to HPAI A(H5N1) and describe trading practices of poultry in eight live bird markets in Sukoharjo. A cross-sectional study was conducted in traditional markets. Total 75 traders were selected using simple random sampling proportionally from 221 traders in all eight markets. Serum samples were tested for H5N1 antibody titer by hemagglutination inhibition test. There was no trader with positive H5N1 antibody. Majority of the traders washed carcasses (84.0%), used containers to carry poultry and carcasses (94.7%), and cleaned places of trading (94.7%). Poultry traders had not been infected by HPAI A(H5N1).
