A58: Granuloma inguinale

There are diseases that are particularly transmitted during sex. These diseases are also called sexually transmitted diseases. They are usually caused by specific pathogens. The pathogens can for instance be transmitted via vaginal fluid or semen. The pathogens may also be transmitted from a sick mother to her new-born child when she gives birth.

One to several weeks may pass between infection with the bacteria and the first symptoms. When the bacteria have contact with the damaged skin or mucous membranes, they can penetrate the skin. As a result, the skin can become inflamed. Painless lumps then usually form. The lumps are typically itchy. Several deep painless wounds can develop from the lumps. These wounds usually form on the genitals and anus.

You may also have other symptoms. If the wounds get bigger, the surrounding tissue can be severely damaged. Scars may also develop. The bacteria can moreover spread in the body and damage organs or bones, for example. You may also have a fever.

The disease occurs in India, Brazil and West Africa especially.
