Patients with recurrent genital herpes attending a sexually transmitted disease clinic were studied and transmission of the infection was elucidated by evaluating serostatus in their partners. Of 84 patients attending for recurrent genital herpes, 94% had a herpes simplex virus type 2 (HSV-2) infection and only 6% (5 patients) a type 1 infection. The mean age of the patients was 36 years and the duration of their infection was up to 37 years (median 4 years). In most patients the number of recurrences had not decreased between the first year and the last year. About half had experienced a more severe first episode infection. Of the patients, 64 % were not aware of asymptomatic shedding and the risk of sexual transmission without clinical symptoms. Of 67 steady partners of patients with genital HSV-2, 15% had a history of genital herpes. By HSV serology, HSV-2 antibodies (indicating subclinical genital herpes) were demonstrated in more than half of the partners. The duration of the relationship or condom use did not seem to influence the frequency of transmission to the partner, which may indicate an individual susceptibility for acquiring a genital HSV-2 infection. Eleven per cent of the patients were on suppressive antiviral therapy, while 39 % had no experience of antiviral therapy. Type-specific HSV serology was found to be of value in counselling partners of patients with genital herpes.
