Knowledge, attitudes and practices towards avian influenza among live poultry market workers in Chongqing, China.

BACKGROUND

Live poultry market (LPM) workers are at high risk of infection with avian influenza virus due to frequent occupational exposure to poultry. This study aims to assess the knowledge, attitude and preventive practice regarding avian influenza among LPM workers in Chongqing, the largest municipality directly under the central government of China.

METHODS

216 LPM workers were recruited by two-stage cluster sampling and interviewed face-to-face using a structured questionnaire. Hierarchical logistic regression analysis was performed to explore factors associated with preventive practices against avian influenza and views on government control measures.

RESULTS

Nearly half of respondents failed to recognize contact with sick birds or excrement as a risk of infection. Less than half the respondents perceived themselves to have a personal susceptibility to be infected or would like to enhance personal protection. Respondents did not pay sufficient attention to wearing preventive clothing such as gloves (43.1%), aprons/garments (33.3%) and face masks (26.9%) when handling live poultry. Few respondents were supportive to market control measures such as a ban on birds' overnight storage (26.8%) or a regular rest day (32.4%). Being older, being more highly educated, having worked longer with poultry, having better knowledge, having more access to information, and perceiving more personal susceptibility to the disease were positively associated with preventive practices. Having higher personal income, longer engagement with poultry work, better knowledge, more awareness of personal protection were positively associated with agreement with government control measures.

CONCLUSIONS

LPM workers in Chongqing showed low level of knowledge, weak perception of susceptibility to avian influenza and inadequate preventive behaviors. Health education campaigns need to better target the knowledge on transmission routes and potential outbreak threat of avian influenza. More attention should be paid to LPM workers who are younger, less educated, with shorter occupational years and lower personal income.
