This study evaluated the success of a national program for the prevention of mother-to-child transmission (MTCT) of HIV-1 in 874 mother-infant pairs from Buenos Aires and surroundings. This population was referred to the National Reference Center for AIDS for diagnosis of neonatal infection during 1993-2000. The data revealed an increase in the use of antiretroviral therapy during pregnancy from 3.2% in 1993-1994 to 73.1% in 1999-2000 and in the use of cesarean delivery (reaching 54.8% in 1999-2000). However, the proportion of HIV-infected women who continued to breast-feed their children remained steady (around 12%). General improvement of the conditions for decreasing MTCT resulted in a significant decrease in the proportion of infected infants from 37.3% before 1995 to 10.7% in 1999-2000 and even 6.5% during 2001. Data on the time of diagnosis indicated that only 42.7% of the women knew about their HIV status before pregnancy, 44.8 knew during pregnancy, and 12.3% knew after the birth of their child. The main risk factor for HIV infection in the mothers was heterosexual contact (73%), and in the fathers, it was injection drug use (67%). These results point out the urgent need to develop additional strategies for prevention of MTCT of HIV-1 to generalize education, counseling, and testing of young women.

CRF01_AE and CRF07_BC are predominant circulating HIV-1 subtypes in China. In this study, we report two novel HIV-1 CRF01_AE/CRF07_BC recombinant forms isolated from one man who has sex with men (MSM) (BDD027) and one mother-to-child transmission (MTCT) case (BDL123) in Baoding City, Hebei Province, China. The recombination breakpoint analysis showed that the recombination pattern of the near-full-length genome of BDD027 consisted of two CRF07_BC fragments inserted into a CRF01_AE backbone, while the recombination pattern of the near-full-length genome of BDL123 consisted of one CRF01_AE fragment inserted into a CRF07_BC backbone.

Mother-to-child transmission (MTCT) of HIV-1 and associated mortality continue to occur at unacceptably high rates, despite the extensive rollout and implementation of Prevention of Mother-to-Child Transmission (PMTCT) Programs, including the modified versions of Option B and B+ in 2010 and 2012, respectively. Maternal HIV viral load (VL) and socio-behavioral factors sustaining MTCT in Rwanda remain largely unexplored. The study examined the effects of socio-behavioral factors on maternal VL and their contribution to transmission of HIV-1 in the context of Rwanda's HIV epidemic.

Introduction: Despite scale up of Option B+, long-term retention of women in HIV care during pregnancy and the postpartum period remains an important challenge. We compared adherence to clinic appointments and antiretroviral therapy (ART) at different follow-up time points between enrolment and 24 months postpartum among pregnant women living with HIV and initiating Option B+ randomized to a peer group support, community-based drug distribution and income-generating intervention called "Friends for Life Circles" (FLCs) versus the standard of care (SOC).
Methods: Between 16 May 2016 and 12 September 2017, 540 ART-naïve pregnant women living with HIV at urban and rural health facilities in Uganda were enrolled in the study.
