YAWS SYMPTOMS |
|
|
Yaws is caused by a spiral-shaped
bacterium (spirochete) called Treponema pertenue. This bacterium
belongs to the same family as the bacterium that causes syphilis.
Yaws is passed among people by direct skin contact. It requires some
kind of a scratched or insect bitten area in order for the bacteria
to actually settle in and cause infection. An injured spot on the
leg is the most common part of the body through which the bacteria
enter. Young children, who are constantly bumping themselves in
play, who wear little clothing, who do not wash their hands often,
and who may frequently put their hands in their mouths, are
particularly susceptible.
The first symptom of yaws occurs three to four weeks after acquiring
the bacteria. The area where the bacteria originally entered the
skin becomes a noticeable bump (papule). The papule grows larger and
develops a punched-out center (ulcer), covered with a yellow crust.
Lymph nodes in the area may become swollen and tender. This first
papule may take as long as six months to heal. Secondary soft, gummy
growths then appear on the face, arms and legs, and buttocks. These
soft, tumor-like masses may grow on the soles of the feet, causing
the patient to walk in an odd and characteristic fashion on the
sides of his or her feet (nicknamed "crab yaws"). More destructive
tumors may then disrupt the bones of the face, the jaw, and the
lower leg. Ulcers around the nose and on the face may be very
mutilating. |
