[Syphilis, the forgotten disease]

The incidence of syphilis was decreasing during the last decades of the 20th century, partly due to the awareness and fear of hiv. However, an increase is now apparent in many countries. It is still uncommon in Sweden compared to chlamydia and gonorrhoea, and the incidence is 4.6/100.000 inhabitants. The infection can be latent and without symptoms, but also manifest itself as a painless genital ulcer, with rash and fever, or as neurosyphilis. Congenital infection due to transmission of the syphilis spirochete from an infected mother to her fetus is still a problem in many parts of the world. In order to prevent congenital syphilis it is important for all pregnant women to have access to maternal care during their pregnancy, and to get efficient treatment if diagnosed with syphilis.
