FRAMBCESIA TROPICA 



Late Manifestations. 



Harper, in Fiji, where syphilis is said to be absent, affirms that 

 tabes, general paralysis, aneurism and gangosa are late manifestations 

 of yaws. 



COMMUNICABILITY. 



The disease is not hereditary. Two-thirds of the patients get it 

 before puberty. Parents are infected from their children more than 

 children from their parents, as a result of the child suckling, when the 

 mother will have the primary yaw on the nipple or breast and as a result 

 of the child being carried astride the hip, when the primary yaw will 

 appear in that position. 



Infection is by direct contact; a damaged surface is necessary. 



Insects may carry the disease, for they eagerly crowd on the open 

 sores and suck the secretion which may be deposited later upon the 

 damaged skins of other people (Robertson). 



The mortality is low, 2*5 per cent, in treated cases, but the working 

 capacity is much reduced. 



Immunity is usually afforded after the first attack. 



The habits of the people predispose them to the disease, the hand- 

 ing round of chopsticks and water-pipes from mouth to mouth and the 

 employment of sleeping mats common to all.
