Increasing number of Chlamydia infections--how can we reverse this trend?

The incidence of chlamydia in Göteborg, the second largest city in Sweden, increased by 81 percent between 1995 and 2001. The majority (82%) of men and women diagnosed with chlamydia were aged 15-29 years. The incidence of chlamydia was higher among teenagers from areas of lower socio-economic index during the first years of the study but after 1995 there was no difference between low and high socio-economic groups. Chlamydia tests were taken three times more often in women than men. Analysis of original data from the Swedish survey of sexual behaviour 1996 demonstrated a strong correlation between the number of sexual partners and STD. Strategies for preventing the spread of chlamydia should be to a greater extent directed towards men and include better accessibility for men to STD clinics as well as a general improvement in contact tracing. The general public should be informed about the fact that chlamydia infections do not always give symptoms and may lead to infertility. Campaigns about condom use in order to avoid chlamydia, HIV-infection and other STD are needed.
