Focus group discussions were held with women attending slum-based antenatal clinics and with male partners of pregnant women separately to evaluate knowledge and attitudes regarding sexually transmitted diseases (STDs) and acceptability of a proposed antenatal STD screening and treatment programme, including partner management. Subsequently, antenatal women found to have a STD were asked to refer their partner(s) for STD treatment. The institution's routine procedure of internal referral to the curative center was evaluated for loss to follow-up. Focus group participants described common STD syndromes, knew that a pregnant woman could transmit a STD to her child, and knew that all sex partners needed to be treated for STDs. Discussion participants disagreed on the possibility of asymptomatic STDs and mentioned other ways of contracting STDs beside sexual transmission. The response to the proposed programme was positive. Of 331 male partners named by antenatal women who were found to have at least one STD, 101 (30%) presented at the clinic through index referral, and an additional 38 (11.5%) presented because of health worker referral. Of the 59 men sent to the curative center for care, only 26 (44%) received treatment. The study demonstrated that in Haiti, partners of antenatal STD patients can be treated without apparent adverse effects. However, internal referrals to separate treatment centres should be avoided. Following this study, education efforts have emphasized the curable nature of STDs, the threat of vertical transmission, and frequent asymptomatic presentation of STDs to promote prevention and treat more partners of STD patients.
