HIV, Hepatitis B, Hepatitis C, and Syphilis: prevalence and serodiscordance between women and their partners

Scherer, Aline; Silveira, Mariângela Freitas da; Nunes, Bruno Pereira

Introduction:

The prevention of vertical transmission of sexually transmitted diseases is the object of research by several authors, who reinforce the importance of knowing the serological status of a woman's sexual partner.

Objective:

To evaluate the prevalence and serodiscordance of HIV, hepatitis B, hepatitis C, and syphilis infections among women admitted to a maternity hospital in southern Brazil and their partners.

Methods:

350 women and their partners were interviewed in a service-based cross-sectional study conducted from August 16 to November 23, 2018.

Results:

4.0% of the women and 4.3% of the men had one of the infections studied. Among women, 2.0% already knew they were HIV positive, 2.0% had a positive rapid test for syphilis and there was no positive result for hepatitis B or C. A total of 299 (85.4%) partners were located. Of these, 293 (98.0%) agreed to answer the study questionnaire. Of all men interviewed, 281 (95.9%) agreed to undergo an rapid test. Among men, 1.4% already knew they were HIV positive and 0.4% had chronic hepatitis B disease. There was a similar percentage of men with a positive rapid test for syphilis and hepatitis C (1.4%). Regarding couples, 6.8% had some positive test. Most of the positive test subjects were in a serodiscordant relationship (16 serodiscordant couples and 3 positive concordant couples).

Conclusion:

These results reinforce the importance of testing men to prevent the infection of a negative partner and the vertical transmission of sexually transmitted infections. The high acceptance, by men, to undergo an rapid test at the time of the woman's hospitalization demonstrated the viability of this strategy in the maternity ward.
