Prevalence of Chlamydia trachomatis and Neisseria gonorrhoeae infections in Greenland. A seroepidemiological study.

In a sero-epidemiological study of the prevalence of chlamydial and gonococcal infections in Greenland three groups of subjects were studied--262 patients attending an outpatient department in the town of Nuuk (of whom 12% harboured Chlamydia trachomatis and 54% Neisseria gonorrhoeae), 63 controls from the same town, and the entire population of 150 in the settlement of Uvkusigsat. Using a microimmunofluorescence test evidence of exposure to C trachomatis was found in 79% of the female and 26% of the male patients, in 12% and 50% of the female and male controls respectively, and in 51% and 21% of the female and male populations of Uvkusigsat respectively. Using an indirect haemagglutination test antibodies to gonococcal pili were found in sera of 92% of the female and 70% of the male patients, in 30% of the male and 10% of the female controls, and in 41% of the women and 33% of the men in Uvkusigsat. The study indicates that genital chlamydial and gonococcal infections are serious public health problems in Greenland and that such infections are acquired early in both sexes and often occur concomitantly.
