Syphilis

2013-11-13 来源: 类别: 更多范文

Syphilis Syphilis is a sexually transmitted disease caused by the spiral bacteria called Treponema pallidum. Syphilis consists of three main stages, primary stage, secondary stage, and latent stage. The latent stage may lead to a final stage called the tertiary stage. There are many cures to syphilis, and it is virtually eliminated from today's society. There are a few ways to contract the disease, all of which can be prevented. The primary stage of syphilis is characterized by a small lesion, called a chancre, which resembles a pimple, blister or open sore. This occurs anytime between nine days and three months after infection. Fluid from the chancre is extremely infectious, but usually painless. Normally it appears on the genitals or near where the bacteria entered the body. It often hides and many people never realize that it is there. On women, the sore can be found hidden in the vagina or the folds of the labia. On men, it usually hides in the folds of the foreskin, under the scrotum, or near the base of the penis. Men more often than women will also have swollen lymph nodes in the groin. At this stage, the chancre is very infectious.
