Study On The Epidemiology Of H5N1Avian Influenza Of Poultry Workers In Jiande City

[Objective] To master the status of avian influenza H5N1virus infection in the population of poultry workers, and distribution of H5N1in environment in Jiande city, to understand the knowledge, attitudes and practice of avian influenza in the population of poultry workers, to provide science basis for making prevention and control measures of human avian influenza.[Methods]185people were collected, the whole population of poultry workers in Jiang'zhu village and Zhang'chun village of Lian'hua town, where have been occurred in poultry outbreaks of avian influenza. To carry out epidemiological questionnaire, collect serum samples from poultry workers to detect the H5N1avian antibodies levels. To collect samples of water, birds feces and poultry baske from poultry farming, sampling every quarter, Using Real-time PCR method to detect the avian influenza H5N1virus antigen. Using the software of Epidata3.0to input the datas, and SPSS13.0to do statistical analysis.[Results] Among the185questionnaires in2009, the rate of male was44.86%, and female was55.14%. Most of them were in the age group of41-60years old,84.33%of them had only junior high school or lower education, and the most were exposed to chicken, accounting for78.92%;31.35%of them had contacted with dead poultry in a month, only one people had been injected influenza vaccine in the nearly one year.69.73%of the them work with ventilation equipment,85.41%with water flushing device and74.05%with liquid soap or soap.The rates of known of the source of avian influenza infection is84.86%,81.62%of them know avian influenza is preventable and controllable disease,57.30%of them know that is high fatality rate,25.41%of them know that is without specific medicine. About the route of transmission:the rates of awareness about route of transmission of airborne infection, dung-mouth, palpebral conjunctiva or broken skin were54.59%,65.41%and47.03%, all the three ways correctlly answers accounted for only11.89%. With different educational background, the witting rate of the avian influenza transmission had significant difference, ?2=11.60,10.03,13.64, P<0.05. With different age, the witting rate of the avian influenza transmission through palpebral conjunctiva or broken skin had significant difference, ?2=8-09, P<0.05. Clinical symptoms:the rates of awareness about clinical symptoms that fever, cough, runny nose and sore throat is81.08%,72.97%,74.59%and41.62%, all the above four kinds of symptoms correctlly answers accounted for20.54%. With different educational background, the witting rate of the clinical symptoms of fever, cough, and sore throat had a significant difference, ?2=7.592,8.349,10.645, P<0.05. With different age, the witting rate of he clinical symptoms had a significant difference, ?2=17.94,54.42,44.82,15.03, P<0.01. The sources of avian influenza are mainly in television and brochures, respectively82.16%and71.35%.The attitude and personal protection:24.86%of them think that themselves will impossibly be infected with avian influenza. The rates of people take measures of protective clothing, gloves and masks when closely exposed to poultry is63.2%,28.1%,4.3%.74.1%of them will wash their hands after contact with poultry. Comparison of male and female, the rates of people take measures of protective clothing and wash hands after contact with poultry had significant difference. With different educational background, the rates of people take measures of gloves and wash hands after contact with poultry had significant difference. Exclude the influence of education, the rates of the female to wash hands after contact with poultry is higher than the male.In2009,171poultry serum samples were not detected the avian influenza H5N1virus antibody, thereinto2samples of HI titer was1:20, the remaining169samples the titer of HI was less than1:10.From2009to2011,192copies of environmental samples were not detected by avian influenza H5N1virus and type A, type B influenza virus.[Conclusion] Research has revealed that there were not influenza H5N1virus detected among the population of poultry workers or in environment of poutry feeding in Jiande city. But educational background of the poutry workers is very low, the knowledge of avian influenza and the awareness of personal protection is not enough. It's necessary to strengthen health education and health promotion, improve the preventional knowledge of the population of poultry workers and the awareness of personal protection.
