What is the death rate of leprosy?

Results: Leprosy was identified in 7732/12 491 280 deaths (0.1%). Average annual age-adjusted mortality rate was 0.43 deaths/100 000 inhabitants (95% CI 0.40-0.46). The burden of leprosy deaths was higher among males, elderly, black race/colour and in leprosy-endemic regions.
