What geographical regions are primarily associated with the organism responsible for bejel?

Bejel, also known as endemic syphilis, is primarily associated with certain geographical regions where the bacterium Treponema pallidum subspecies endemicum is prevalent. These regions include parts of the Eastern Mediterranean, North Africa, and the Balkans. The transmission of this infection tends to occur in areas where poor sanitation and overcrowded living conditions are common, contributing to its endemic nature.

This understanding highlights the geographical distribution of bejel, confirming that all the mentioned regions are relevant in its dissemination. Each of these areas has reported cases of bejel, indicating that the organism's presence is not limited to a single location but is widespread across these diverse regions. Hence, identifying all of these areas as associated with bejel is accurate, supporting the answer that encompasses all of them.
