Yaws is a common chronic infectious disease that occurs mainly in warm humid regions such as the tropical areas. Yaws usually features lesions that appear as bumps on the skin of the face, hands, feet, and genital area. The disease most often starts as a single lesion that becomes slightly elevated, develops a crust that is shed, leaving a base that resembles the texture of a raspberry or strawberry.
HOW IS YAWS DIAGNOSED?
The clinical diagnosis can be confirmed by examining a sample from a skin lesion under a special type of microscope (darkfield examination). There is no specific blood test for yaws, but because it is closely related to the bacterium that causes syphilis, the blood tests for syphilis are diagnostic in yaws as well.
HOW IS YAWS TREATED?
An intramuscular injection of penicillin is given to treat Yaws. Other medication like azithromycin is more effective than penicillin. Tertiary stage of Yaws develops when the primary and secondary stages are left untreated. The effects of this stage cannot be reversed
DID YOU KNOW?
Without treatment, about 10% of affected individuals would develop disfiguring and disabling complications after five years because the disease may cause gross destruction of the skin and bones. It can also cause deformities of the legs, nose, palate, and upper jaw.There is no vaccine to prevent Yaws. The principles of prevention are based on the interruption of transmission by early diagnosis and treatment of affected individuals and their contacts.
