From August 1, Guangzhou will further expand the scope of restricted living areas for live poultry. The monitoring data of the Guangzhou City CDC showed that since Guangzhou set up a restricted living area for live poultry, the positive rate of the environmental specimens in the restricted area contaminated with the bird flu virus was significantly lower than the unrestricted area. Since the winter of last year, new cases of human bird flu in Guangzhou have occurred in non-restricted areas.
Li Tiegang, chief physician of the Guangzhou Municipal Center for Disease Control and Prevention, said that before there was a restricted area of ​​live poultry and a non-restricted area across the street, people in the restricted area were free to purchase live poultry in non-restricted areas, which was detrimental to the overall epidemic prevention and control situation; After further expanding the scope of restricted areas of live poultry, the restricted areas of the central city area are connected to one another, which is conducive to the management of the live poultry market and the prevention and control of the epidemic in the entire city.
At present, the Guangzhou Municipal Center for Disease Control and Prevention has set up 185 monitoring sites for poultry markets in the 11 districts of the city, covering all streets and towns in the city. The data shows that the positive rate of environmental samples of live bird transaction restricted areas contaminated with bird flu virus is 20% lower than that of non-restricted areas. Li Tiegang said that from the perspective of disease prevention and control, the continued expansion of the restricted area for live poultry operations is a major trend in the future.
It is understood that, according to the law of previous years, Guangzhou, people infected with bird flu cases occur mostly in the winter and spring. This year's peak of human bird flu infection has passed. Recent monitoring shows that the current epidemic of bird flu virus in Guangzhou's external environment is at a low level.
