This study was carried out in two medical facilities in Enugu, Nigeria, from September to November 2007. An interviewer-administered questionnaire was used to collect data from HIV-positive pregnant women accessing PMTCT (prevention of maternal-to-child transmission) services at the two centres. Ninety-two women were interviewed: 89 (96.7%) had disclosed their status, while 3 (3.3%) had not. Of the 89 women who had disclosed, 84 (94.4%) had disclosed to partners, 82 (92.1%) to husbands, 2 (2.2%) to fiancés, 18 (20.2%) to sisters, 13 (14.6%) to mothers, 10 (11.2%) to brothers, 10 (11.2%) to fathers and 10 (11.2%) to priests. Fifty-two (58.4%) gave emotional support as the reason for disclosure and 46 (51.7%) gave economic and financial support as reasons. Fifty-six (62.9%) reported understanding from partner as a positive outcome and 44 (49.4%) reported financial support. Forty-six (51.7%) reported no negative outcome. Serostatus disclosure rate in this study was high with most women disclosing to their partners.
