Relation between the HIV and the re-emerging syphilis epidemic among MSM in Germany: an analysis based on anonymous
Sexually Transmitted Infections
|December 6, 2005
Abstract:
In 2003, for the first time since the introduction of highly active antiretroviral therapy (HAART), the number of newly diagnosed HIV infections in Germany increased considerably compared to the previous year. The increase was largely restricted to men who have sex with men (MSM) from larger cities. In this group the number of newly diagnosed HIV infections increased about 30% compared to 2002. Since the late 1990s syphilis infections among MSM also increased in Germany, concentrated in larger cities.

Amebiasis
Entamoeba histolytica, a protozoan parasite, is responsible for intestinal and extraintestinal amebiasis. Though a significant proportion of infections remain asymptomatic, approximately 50 million individuals annually are estimated to present with clinical disease, resulting in up to 100,000 deaths globally. The disease burden is disproportionately high in regions with lower socioeconomic status, such as parts of India, Africa, Mexico, and Latin America.Etiology and TransmissionThe infective...
Genital Herpes
Genital herpes is a sexually transmitted infection primarily caused by herpes simplex virus type 2 (HSV-2), though herpes simplex virus type 1 (HSV-1) is increasingly implicated in genital infections, particularly among younger populations. Transmission occurs mainly through sexual contact, with asymptomatic viral shedding serving as a major route of spread. This characteristic makes HSV-2 difficult to control at a population level, as individuals may unknowingly transmit the virus even in the...
Sexually Transmitted Infections
Sexually transmitted infections (STIs) are diseases transmitted primarily through unsafe sexual interactions. Bacteria, viruses, or parasites cause them and can result in severe health complications if untreated.ChlamydiaThe bacterium Chlamydia trachomatis is responsible for the disease Chlamydia, the most common STI in the United States. This peculiar pathogen requires human cells to reproduce, residing intracellularly. The initial infection often goes unnoticed because it typically does not...
