Analysis Of The Plague Surveillance In Tibet From 2005 To 2010

Plague is caused by the Yersinia pestis, which is suffering from human and beast. Plague is a deadly infectious disease, which was listed as one of the key prevention and control infectious disease by the World Health Organization. Plague does not rely on human beings and it exists in nature for a long time. It has already happened three times pandemics in the world. Since the 1990s, an upward momentum of Plague epidemic has happened in China. The situation is not optimistic. China has a complex and diverse natural plague foci, many of them are in a dynamic state. Plague continue to happen in successive years in some areas, at the same time our country is facing a serious threat of plague. Especially in western China, there is a large area of natural plague foci. With the development of strategy implementation in western China, human activities frequently happened in the plague epidemic areas, thus it leads to an increase risk factors of plague objectively. In Tibet plateau of China, there is Tibetan plateau Himalayan woodchuck plague natural epidemic. And in this region, plague is not only active, but also its poisonous is strong. Research has shown that as long as there is a virulent plague bacillus enter the human body, and it is enough to cause disease, and in a large proportion leads to pneumonic plague in human-beings.Tibet plague monitoring data shows that plague has happened among animals for a long time in Tibet, and it happened successively human-to-human. Especially in recent years. Tibet plague natural epidemic disease areas increase rapidly. And also there are many species of infected animals, which pose a major threat to the health of the people.It is visible that prevention of plague is still a long-term task and the priority work in the Tibet Autonomous Region. [objective] This article analyzes the Plague surveillance data of the 2005-2010 in Tibet himalaya marmot foci; explore the prevalence law of Tibet plague, and the relationship between the animal and human epidemic. So that we can provide a theoretical basis for plague prevention and control and provide a scientific basis for prevention and treatment of plague.[Methods] In this study, the Tibet Autonomous Region from 2005 to 2010 analyzes the characteristics of the plague. The prevalence of the epidemic from the range of animals, popular strength.The main host and the density of small-scale plague and its relationship point of the epidemic of animals were analyzed. This examination studied and discussed the distribution of human plague in the three characteristics, the source of infection and transmission, human outbreaks of disease type, mortality, the linear relationship between human plague and animal plague in Tibet and other issues. Use a Epidata3.02 for data entry and collation. Use spss13.0 for statistical analysis. The main method of statistical analysis is Chi-square analyze, linear Regression and correlation.[Results] From 2005 to 2010, the Tibet Autonomous Region added 11 natural foci of plague counties, the plague foci area increased rapidly. During the study period 2518 animals,210 animal positive cases were detected by the Tibet Autonomous Region and the positive rate was 8.3%. In 6 years.32148 animal serum materials were detected in the Tibet and The positive rate was 1.03%. it continued popularity of higher strength. The Tibet accumulated 11414 Rex, main reservoir of plague density was 0.04-0.16 only/ha and marmota average density was 0.08/ha in Tibet. The statistical analysis shows that there's no linear correlation between the Tibetan animal plague and Himalayan marmot density.6 years in the observation of the Tibet Autonomous Region occurred 3 cases of human plague, the incidence of 13 people, including 11 cases of males and 2 females. Outside people who infected with the plague accounted 38% for the total number of human plague cases in Tibet. The human plague mainly occurred in Zhongba County and Long County in June and September. The modes of transmission mainly include direct contact and animal media communications; The largest proportion in Clinical classification were lung plague.[Conclusion] From 2005 to 2010, the Tibet Autonomous Region added 11 natural foci of plague counties, the plague foci area increased rapidly:During the study period, the animal plague in Tibet continued popularity of higher strength; Outside Tibet Autonomous Region accounts for a certain percentage of the population infected with the plague between 2005-2010. In the human pulmonary lung plague outbreak in the main and the cases of male patients were far more than women; The study shows that there's no linear correlation between the Isolation rate of animal bacteria and main host density.
