Abstract:
ObjectiveTo study the epidemiological characteristics of leprosy in China,2001-2010.MethodsData were collected from the database of the national system of leprosy surveillance.A descriptive and comparative analysis was performed.ResultsTotally,15 507 new leprosy cases were detected from 2001 to 2010 with an average case detection rate of 0.118 per 100 000 population.Among these cases,2.7％ were children under 15 years,86.5％ multibacillary,and 22.5％ suffered from grade 2 disability.From 2001 to 2010,a total of 1506 relapse cases were detected,and relapse occurred after multi-drug therapy(MDT) in 464 of these cases.There were significant differences between low and high endemic areas in the proportion of children under 15 years,females,immigrant patients among newly detected patients as well as the proportion of cases of relapse after MDT among all the relapse cases.By the end of 2010,the registered leprosy cases were 6032 with a prevalence rate of 0.450 per 100 000 population,among whom 2886 were under MDT.ConclusionsThe leprosy case detection rate continued to decrease in China from 2001 to 2010 with an unequal distribution.The pocket areas were in Yunnan province,Guizhou province,Sichuan province,Guangdong province,Hunan province and Tibet Autonomous Region.It is warranted to enhance the control of leprosy and reduce the prevalence of disability due to leprosy.
