How often are gonorrhoea and genital yeast infection sexually transmitted?

Abstract
Although gonorrhea is often regarded as the sexually transmitted disease against which others are measured, its infectivity is not clearly understood. Estimates of the infection rate have varied from 5-90%. Couples (50) with gonorrhea were matched with 50 couples with genital yeast infection. Gonorrhea was diagnosed in both partners of 32 couples and genital yeast infection in both partners of 21 couples. These figures provide an indication of te sexual transmission of these conditions. The higher figure for gonorrhea may be related to a greater urgency in tracing contacts.
