Summary
Leprosy (Hansen's disease) remains a public health concern in China, with uneven distribution and pockets of higher prevalence. Continued efforts are crucial for leprosy elimination, especially in high-risk areas.
Area of Science:
- Epidemiology
- Public Health
- Infectious Disease Control
Context:
- Leprosy (Hansen's disease) surveillance in China.
- Analysis of national leprosy surveillance data from 2009.
Purpose:
- To characterize the epidemiology of leprosy in China.
- To inform targeted leprosy control strategies.
- To assess progress towards leprosy elimination goals.
Summary:
- In 2009, China detected 1597 new leprosy cases (0.120/100,000 population), with 2.4% in children, 84.3% multibacillary, and 22.8% with grade 2 disability.
- 148 relapses were reported, including 69 post-multi-drug therapy. Total prevalence was 6603 cases (0.049/10,000 population), with 3332 on multi-drug therapy.
- Leprosy is low endemic overall but unevenly distributed, with high-burden areas in Yunnan, Sichuan, and Guizhou.
Impact:
- Provides evidence for developing specific leprosy control strategies in China.
- Highlights the need for sustained input and effort to achieve leprosy elimination.
- Identifies key demographic and clinical features of new and existing leprosy cases.
