RESUMEN
Objective To understand the geographical features of malaria in Yunnan Province,so as to provide the refer?ence for malaria elimination. Methods The data of malaria in Yunnan Province from 2012 to 2015 were collected and ana?lyzed. Results Totally 2 586 malaria cases were reported in Yunnan Province from 2012 to 2015,in which 274(10.60%) were local cases and 2 311(89.37%)were abroad imported,and one(0.03%)was domestic imported. The imported malaria cases and local cases were analyzed according to the sources and locations respectively,and the arithmetic means of the num?bers of imported and local cases were 96.29 and 10.96 respectively,the standard deviations of the numbers of imported and local cases were 421.18 and 19.12 respectively,and the difference of the means was not significant(Z=-0.326,P>0.10). Both the imported and local malaria cases could be clustered into five sections by the number of 5. The Herfendal?Hirshman indexes of the imported and local malaria cases were 8 121 and 1 598 respectively. Conclusions There is no significant difference of the distribution between the imported and local malaria cases,and they should be attaching equal importance. The non?uniform de?gree of imported cases is higher than that of the local cases,while both of them could be divided into five major clusters in the prevention and control work.
RESUMEN
Objective To analyze the malaria endemic situation in Jingmen City from 2005 to 2014,so as to provide the evi?dence for revising the measures of malaria elimination. Methods The malaria endemic data of Jingmen City from 2005 to 2014 were collected and analyzed. Results Totally 516 malaria cases were reported during the 10 years in Jingmen City,and the av?erage annual malaria incidence was 0.17/10 000,which was declining year by year. The local infection of malaria cases were 484(accounted for 93.80%)with obvious aggregation in June,July and August,which were also relatively aggregated in farm?ers(accounted for 60.08%). The ratio of male to female was 1.93∶1. No local cases of malaria infection were reported from 2012 to 2014. The imported malaria cases were 32(accounting for 6.20%),showing a rising trend in recent years. Conclusion The incidence of malaria is low and has a downward trend year by year from 2004 to 2015 in Jingmen City. However,the imported malaria cases are increasing in recent years,and the surveillance and management of them should be paid more attention to.
RESUMEN
Objective To understand the epidemic situation and characteristics of malaria in Yunnan Province,so as to pro?vide the reference for malaria elimination. Methods The data of malaria reported in the information system were collected and analyzed in Yunnan Province from 2011 to 2013. Results From 2011 to 2013,totally 2 256 malaria cases were found in Yun?nan Province,with a morbidity of 0.162 8 per million and three of them were death cases. The local cases mainly distributed along the boundary and accounted for 29.48%,while the imported cases mainly came from Myanmar and accounted for 70.52%. The number of endemic counties with local malaria cases decreased from 37 to 10 during the three years. The number of import?ed cases reached the peak in May and the local cases in June. The patients were mainly aged from 20 to 49 years old(accounted for 70.58%),and 85.24% of the cases were peasants and laborers. Totally 86.66% of cases were laboratory confirmed cases, and 13.14% were clinically diagnosed. The proportions of cases reported by hospitals,health service centers and CDCs were 33.02%,37.06% and 29.92%,respectively. Conclusions The prevalence of malaria in Yunnan Province decreased from 2011 to 2013. The work of malaria cases double?checked by province?level CDCs is effective. However,the awareness and accurately diagnostic capability of clinical doctors still should be strengthened.
