Bejel is a chronic bacterial infection caused by the bacterium Treponema pallidum subspecies endemicum. It primarily affects the skin and bones, leading to lesions and deformities, particularly in children. The disease is most common in regions with poor sanitation and limited access to healthcare, often spreading through direct contact with infected individuals. The symptoms of bejel typically include sores or ulcers on the skin, especially around the mouth and nose, and can progress to more severe complications if left untreated. Treatment usually involves antibiotics, such as penicillin, which can effectively eliminate the infection and prevent further health issues.
