New case detection
Based on official data from Ministries of Health in endemic countries, the global annual detection of leprosy has shown a declining trend since 2001. New case detection was 407,791 in 2004 but had fallen to 228,474 by 2010, a reduction of around 44%. Tables shown in the first document listed below show both the prevalence and new case detection at regional and country levels, compare new case detection trends over the period 2004-2010, and examine the proportion of child cases and Grade 2 disabilities amongst the new cases detected.
During 2010, the number of new cases detected continued to decline in all regions except the Eastern Mediterranean. More new cases were detected in this region than in earlier years owing to increased coverage of leprosy control services, along with the the provision of better services in southern Sudan.
The proportion of cases with MB leprosy among new cases ranged in the African Region from 61.72% in the Democratic Republic of the Congo to 99.21% in Kenya; in the Region of the Americas, from 40.88% in Brazil to 83.06% in Cuba; in the South-East Asia Region from 42.33% in Bangladesh to 80.96% in Indonesia; in the Eastern Mediterranean Region, from 61.95% in Yemen to 88.38% in Egypt; and in the Western Pacific Region, the proportions ranged from 29.67% in Kiribati to 93.92% in the Philippines.
