The overall prevalence of C. trachomatis infection was 4.2 % in women and 4.6 % in men. A relatively high prevalence of 8.3 % was found in men older than 25 years. Never using condoms was an independent risk factor for infection. The most common symptom was discharge; however, 64.5 % of infected females and all of the infected men were asymptomatic, supporting the need for screening programmes. The most frequently encountered genotypes were E (46.5 %), F (20.9 %) and K (14.0 %). Since the nvCT was detected in one female student, this is one of the rare studies that reports on the molecular identification of nvCT apart from Sweden.
