[Sexually Transmitted Infections in the Tropics].Hautarzt 2018; 69(11):945-959H
Sexually transmitted infections (STI) are common all over the world and the incidence of chlamydia, gonorrhea, syphilis and trichomoniasis alone is estimated at 500 million/year. Of these infections 75% occur in tropical countries in Latin America, sub-Saharan Africa and South as well as Southeast Asia. The bacterial infections chancroid, lymphogranuloma venereum (LGV) and granuloma inguinale (GI, Donovanosis) are termed tropical STI. They occur mainly in tropical countries, i. e. regions situated between the equator and the northern and southern 23.5° latitudes, regions which are characterized by hot humid climates as well as poverty and underdevelopment. These three diseases are primarily associated with ulcerations of the skin, thus their presence represents an increased risk for transmission of HIV and other STI. As with all STI, to minimize the risk of tropical infections it is essential to avoid hazardous sexual practices and to use condoms.
