strategy is warranted, to detect cases earlier, thereby achieving better treatment outcomes.<br />

Burden and distribution<br />

The 33 countries in which Buruli ulcer has been detected have mainly tropical and subtropical<br />

climates (Fig. 4.1.1). About 5000 cases annually are reported from 15 of those countries, but<br />

this number is considered low. Since 2010, the number of reported cases has declined gradually,<br />
