Burden and distribution
By the beginning of 2014, 102 countries (in five regions) had submitted reports on leprosy
to WHO (1). The data were from 20 countries (African Region), 25 countries (Region of the
Americas), 11 countries (South-East Asia Region), 14 countries (Eastern Mediterranean Region)
and 32 countries (Western Pacific Region). The European Region did not submit reports. Midyear
population estimates for 2013 were derived from data published by the United Nations
Department of Economic and Social Affairs/Population Division (2). Fig. 4.10.1 summarizes
the global situation of leprosy at the beginning of 2014.
Fig. 4.10.2 shows the regional distribution of leprosy at the beginning of 2014. The total
number of new cases detected in 2013 and reported by 102 countries was 215 656. Globally, the
number of cases registered at the beginning of 2014 was 180 618.
The number of new cases detected annually continues to decrease in all regions, except in the
African Region (Fig. 4.10.3). The apparent increase in the African Region is due to the transfer
of South Sudan from the Eastern Mediterranean Region to the African Region.
