Evaluation Of The Effectiveness Of H7N9 Avian Influenza Prevention And Control Policy

From 2013 to 2018,the spread of H7N9 avian influenza posed a great threat to the lives of the public and economic development.In order to prevent the spread of epidemic situation,the government has continuously summed up the experience of antiepidemic and invested a lot of money to improve the policy.So whether these measures can effectively control the spread of avian influenza,whether it is economical and timeeffective is worthy of our further discussion.This article takes Suzhou,Wuxi,Taizhou,and Huai’an of Jiangsu Province as the research objects,analyzes its practices against H7N9 avian influenza,and uses the relevant data provided by the Jiangsu CDC and the results of interviews.The cost-effectiveness comparison analysis and intervention policy analysis were conducted from three aspects: the number of patients,the positive rate of H7N9 virus nucleic acid in the market environment,and the incidence of avian influenza,so as to draw conclusions and make policy recommendations.Through a comparative analysis of the prevention and control policy intervention effect and cost effect of four cities in Jiangsu Province,this study found that: First,shut down the live poultry trading market that does not meet the requirements of the "four divisions",suspend live poultry trading during the outbreak period,strengthen measures such as cleaning and disinfection of the market environment can reduce the morbidity and positive rate of viral nucleic acid in the market environment.Then,the costs for H7N9 avian influenza in various regions are related to the number of patients.Finally,strengthening publicity,training and tracing the source of the external environment can effectively control the spread of H7N9 avian influenza.However,there are still some problems in the policies implemented in various places.In the early stage of the epidemic,the closure of the market is not timely enough,which will easily lead to a rise in the number of patients.In the later period of the closure of the market,the lack of government supervision and the relaxation of the public will easily lead to fluctuations in the number of patients and the positive rate of virus in the market environment.Based on the above conclusions,this article recommends that: when there is no bird flu case,local governments should effectively implement the "1110" system,such as one day cleaning and disinfection,one week cleaning,one month off,and the harmless treatment of sick and dead birds.In the susceptible period of bird flu,do sampling and testing,and strengthen the publicity and education of poultry practitioners.After the occurrence of bird flu cases,government departments need to trace the source of the external environment and strengthen the management of close contacts.For areas where there are 2 or more H7N9 avian influenza patients within 30 days,short-term measures should be taken to close the live poultry market.At the same time,the knowledge of prevention and control of bird flu should be popularized scientifically to avoid public panic.In addition,government departments should also establish a designated live poultry trading market,improve the poultry market management system,and actively promote the benefits of eating frozen poultry to the public to prepare for the further promotion of the cold chain poultry market in the future.
