Methods Descriptive analysis of data from the national leprosy surveillance system was carried out in 2009. Results A total number of 1597 new cases were detected in 2009 with a case detection rate of 0.120 per 100 000 population.The proportions of children under 15, multibacillary and disability grade 2 were 2.4%, 84.3% and 22.8% respectively. A total number of 148 relapse cases were reported in 2009, among which 69 cases were those relapsed after multi-drug therapy. The existing cases were 6603 by the end of 2009 with a prevalence rate of 0.049 per 10 000 populations, among which 3332 cases were on multi-drug therapy. Conclusion The overall leprosy situation is considered to be at low endemic in China but the distribution is unequal, with pocket areas in Yunnan, Sichuan and Guizhou. In order to reach the target on leprosy elimination, which was considered as a public health and social problem, the input and efforts are needed for many years to come.
