[FONT=宋] Recently from the provincial Center for Disease Control and Prevention noted that the Centre research team of the year 2013,2014 patients and H7N9 viruses were isolated extracellular environment and gene sequencing comparison found that the risk of infection in the general population is still low, but the elderly, have high blood pressure people with underlying diseases such as diabetes and pregnant women easily develop into a severe illness after etc., need special attention. Additionally, the center of the province outside environment monitoring found that the further spread of H7N9 virus contamination, exposure to live poultry markets are risk factors for onset.
Early human infection with H7N9 virus circulating lower risk
Provincial CDC chief expert in the field of microbial 柯昌文 to reporters, the research team to study the Center found that: H7N9 hemagglutinin antigenic sites in different groups of host-derived highly conserved. "In other words, at this stage, for the general population, whether it is exposed to the patient, sick birds or contaminated outside environment, the risk of H7N9 infection are low." 柯昌文 said. But experts also stressed that elderly people have underlying diseases and pregnant women, due to easy development of severe infection, should be given special attention. Experts advise that such people should avoid live animal markets activities."From the province live animal markets exist outside the environmental monitoring results, and more recently in the presence of H7N9 virus outside market environment pollution, the pollution situation is more serious in some areas, live bird markets are exposed to risk factors for disease. In addition, scattered H7N9 poultry class also has the risk of infection. "CDC expert explained. The farm is not easy to regulate the management of contaminated with the virus, it is safe. "So, H7N9 epidemic prevention and control of focus in live bird markets." Experts stressed.
Control live bird markets can go all out effective prevention and control of human infection with H7N9, while preventing the spread of the virus spreading to farms
Provincial CDC research team also found that H7N9 virus genes in the H7N9 strains isolated in Guangdong, the province has gene fragments with live bird markets higher prevalence of H9N2 virus in the degree of similarity, which is conducive to H7N9 virus The rearranged, may result in the local spread of the virus.
The findings suggest that should be decisive control live bird markets, strengthen the management of live poultry markets, try to reduce the spread of viral contamination in the market. The province has implemented live bird markets, "1110" system, but the current implementation, the "zero population" far from impossible position. Prevention and control of H7N9, deputy head of the expert group province, provincial emergency management experts, director of the provincial Center for Disease Control and Prevention Zhang Yonghui stressed good day zero herds of live poultry retail markets is the key to prevention and control of H7N9 epidemic. "Leftover chicken slaughter must be in place, because if let live bird in the market overnight, and will not be able to do cleaning and disinfection, increases the risk of viral contamination of the market." For whether you can return the chicken farms, said Zhang Yonghui not Line:. "it is possible to do that spread the virus spread from farm to live bird markets." So, Zhang Yonghui reminded live poultry operators in the market after the slaughter of chickens, do the cleaning and disinfection in addition to the scene, but also at the same time transport of live birds of vehicles and containers cleaned and disinfected.
Unconditional and intensive poultry slaughtering areas should be slaughtered in a relatively concentrated area
The province is pursuing "centralized slaughtering of live poultry." But now some small areas or rural areas can not afford to carry out centralized slaughtering. In this regard, Zhang Yonghui think, who can not carry out centralized slaughtering areas, may be considered in a relatively concentrated area. "For example, chickens unified fixed small family workshop to carry out the slaughter, temporary way of this method is the relative concentration of a centralized slaughter. The purpose is to prevent viral contamination and diffusion market." Zhang Yonghui also stressed that in small family workshop in the work of the staff engaged in slaughter must be good personal protection, after slaughter to do the cleaning and disinfection of the environment and personal hands clean. The elderly, people have underlying diseases and pregnant women should avoid contact with live poultry and other groups; fever occurs once, headache, nasal congestion, cough, malaise and other respiratory symptoms should seek immediate medical attention and inform the doctor if there is contact with live birds or live poultry markets exposed History. People with flu symptoms should consult their use of antiviral drugs (such as Tamiflu). "Research shows that early use of Tamiflu and other antiviral drugs, whether in Hong Kong is a popular bird flu or H3N2 and other influenza patients, are very effective." Zhang Yonghui said.
