Yaws

Yaws is a chronic, contagious bacterial infection caused by the bacteria Treponema pallidum subspecies pertenue. It commonly affects the skin, mucous membranes and bone on the arms, legs, trunk and head of the infected person. The infection can cause skin lesions, fever, weight loss, and joint pain and if left untreated can cause severe disfigurement and organ damage. Yaws is primarily seen in tropical and subtropical regions, but can be found in any region where there is poor sanitation and lack of access to healthcare. Treatment for this infection usually involves antibiotic therapy, although early detection and treatment are key for successful treatment and reducing the spread of the disease. Yaws can, in rare cases, be fatal, and is a major cause of disability among those living in tropical regions.
