All of the following are true regarding Yaws EXCEPT
A. Caused by Treponema subtype T. pertenueB. It cross reacts with antibody titer of syphilis
C. Transmitted sexually
D. Common in children
Ans.
C. (Transmitted sexually)
• Yaws is a chronic disease that is usually acquired in childhood and is caused by T.pertenue. It is also known as Pian, framboesia, or bouba.
• The disease is characterized by the development of one or several primary lesions (called the ‘mother yaws’) followed by the appearance of multiple disseminated skin lesions.
• Early lesions may persist for many months, are infectious, usually recur several times within the early years of infection.
• Manifestations are destructive and can involve skin, bone, etc.
• The infection is transmitted by direct contact with infectious lesions.
• Children with open lesions and without clothing are most likely to transmit infection during play or in group.
• Incubation period is 3—4 weeks.
• Lesion begins as a papule, usually on an extremity, (particularly during moist warm weather) to become papular (“raspberry- like” thus the name “framboesia”) lymphadenopathy develops, and the lesion usually heals within six months.
• A generalized secondary eruption, accompanied by generalized lymphadenopathy, appears either concurrent or following the primary lesion, may take several forms, papular, or papillomatous, and may become secondarily infected with other bacteria.
• Painful papillomatous lesions on the soles result in a painful crab like gait (“crab yaws”)
• Periostitis may result in nocturnal bone pain and poiy dactylitis.
• All early skin infections and cutaneous relapses are common during the first five years.
• Late yaws is recognized in 10% of untreated patients manifested by gummas of the skin and long bones, hyperkeratosis of palms and soles, osteitis and periostitis, and hydrarthrosis.
• Lesions are characteristically very destructive and destruction of the nose, maxilla, palate, and pharynx is termed as gangosa and is similar to the destructive lesions seen in leprosy and leishmaniasis
