The grade 2 deformity rate of new patients was 10.08%, 19 percentage points lower than that in 2011 (29.33%). There are no moderate endemic counties, and 116 counties have reached the national standard for eliminating leprosy hazards. There are 11 moderate endemic counties less than that in 2010, and 61 standard counties more than that in 2010.
