What are the hazards of emerging infectious diseases to people's health in China in recent years?

More than ten infectious diseases were added in China on April 4, 2006 14, 16:25 Global Times-Life Weekly. On April 4th, Liang Dongming, deputy director of the Emergency Office of the Ministry of Health of China, said at the Asia-Pacific Economic Cooperation Seminar on Emerging Infectious Diseases that there are at least ten emerging infectious diseases in China, which have caused the epidemic, and there are also possibilities for other emerging infectious diseases to be introduced. Liang Dongming said at the seminar that the incidence of some infectious diseases in China is still high, such as viral hepatitis, epidemic hemorrhagic fever and bacillary dysentery. Some diseases that have been controlled show a trend of epidemic spread, such as tuberculosis, sexually transmitted diseases, schistosomiasis, etc. There are some emerging infectious diseases in China, such as AIDS, SARS and bird flu. In addition, there are other new infectious diseases in China, including Ebola, West Nile and Pani. Liang Dongming said that human beings generally lack immunity to emerging infectious diseases, and early detection and diagnosis of emerging infectious diseases are more difficult, and there is no effective means of prevention and treatment. China should strengthen the prevention and control of this infectious disease. Previously, on March 30th, the Ministry of Health issued the National Key Parasitic Disease Prevention and Control Plan for 2006-20 15. According to the plan, according to the results of the national survey in 2004, the number of people infected with land-borne nematodes in China is about 65.438+0.29 billion, and the infection rate is as high as 20.07%-56.22%, which is distributed in 654.38+0 provinces (autonomous regions/municipalities directly under the Central Government). Although the infection rate is 63.65% lower than that of 1990, the transmission situation is still grim. Soil-borne nematodes refer to nematodes whose eggs or larvae directly infect people after the development of infection in the outside world (mainly soil) without intermediate hosts, such as roundworms, whipworms and hookworms. Soil-transmitted nematode infection is easy to spread in a large area, which will damage many organs of human body, especially children, and even threaten life. For example, ascaris lumbricoides larvae can swim around the human body, causing damage to the intestine, liver, lung, microvessels and lymphoid tissues, or inducing allergies. In severe infection, larvae can enter the systemic circulation, invade multiple organs and cause heterotopic injury; Ascaris adults can ingest human nutrition, leading to intestinal obstruction and complications of ascaris such as biliary tract, pancreatic duct and appendix, which can be fatal in severe cases. In addition, whipworms, hookworms, etc. It is also very harmful to the human body. The Ministry of Health has formulated a five-year plan to curb the spread and prevalence of soil-borne nematodes, which are affected by human living habits, natural and economic environment. By improving environmental sanitation, the reproduction, survival and infection space of parasites can be reduced.
