Yaws, which also affects the skin and bones, occurs in the humid equatorial countries, while pinta, which only affects the skin, is common among the native peoples of Mexico, Central America, and South America.
Pinta is a bacterial infection of the skin that causes lesions, red to bluish-black colored spots and splotches, and discoloration of the skin.
The most significant concern is that if pinta is not diagnosed and treated promptly, the pigmentation changes in the skin may be permanent.
Pinta only affects the skin and does not affect life expectancy, even if not treated, and it can usually be cured completely.
Pinta is a skin infection caused by the bacterium Treponema carateum, a relative of the bacterium that causes syphilis.
Pinta can be diagnosed by dermatologists (doctors who specialize in skin diseases) and infectious disease specialists.
Pinta is primarily found in rural, poverty-stricken areas of northern South America, Mexico, and the Caribbean.
In the 1950s, it is estimated that there were about one million cases of Pinta in South and Central America.
Bejel is related to yaws and pinta, and together the three diseases are referred to as treponematoses.
The second stage of pinta occurs between one and 12 months after the primary lesion stage.
