Sub-regional Trend of HIV Infection Among Antenatal Clinic Attendees in Andhra Pradesh (2003-2019). Curr HIV Res 2022; 20:327-336. [PMID: 35929630 DOI: 10.2174/1570162x20666220805090501] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/15/2022] [Revised: 04/28/2022] [Accepted: 05/25/2022] [Indexed: 01/27/2023]
Abstract
INTRODUCTION The analyses of local risks at sub-national levels and tailored interventions are being emphasized for effective HIV management. Andhra Pradesh (AP) is a high HIV prevalence state in India, with the second-highest number of People with HIV (PWH) and a consistent decline in HIV prevalence at the state level. Probing further into the region and district-wise levels and trends of HIV prevalence will provide critical insights into sub-regional epidemic patterns. Hence, this paper analyzes the regional and district-level trends of HIV prevalence among pregnant women attending antenatal clinics (ANC) from 2003 to 2019 in AP, South India. METHODS HIV prevalence data collected from pregnant women in AP during HIV Sentinel Surveillance (HSS) between 2003 and 2019 was used for trend analysis. The consistent sites were grouped into three regions (Coastal Andhra, Rayalaseema and Uttar Andhra), totaling 39 sites, including 21 rural and 18 urban sites. Regional and district-level HIV prevalence was analyzed using the Chisquare trend test, and spatial analysis was done using QGIS software. For the last three HSS rounds, HIV prevalence based on sociodemographic variables was calculated to understand the factors contributing to HIV positivity in each region. RESULTS In total, 143,211 pregnant women were recruited. HIV prevalence in AP was 0.30% (95% CI: 0.22 - 0.39) in 2019. The prevalence was 0.31%, 0.35% and 0.22% in Coastal Andhra, Rayalaseema and Uttar Andhra, respectively. HIV prevalence had significantly (P < 0.05) declined in all regions. The overall trend indicated that the HIV prevalence was higher among older pregnant women and in urban regions. However, recent trends consistently report HIV positivity among young and new pregnant mothers, illiterates, and rural regions. CONCLUSION The overall trend indicated that the HIV prevalence was higher among older pregnant women and in urban regions. However, recent trends consistently report HIV positivity among young and new pregnant mothers, illiterates, and rural regions. Identifying the contextual risk patterns associated with HIV transmission will further improve HIV preventive and management programs among the general population.

Winskell K, Kus L, Sabben G, Mbakwem BC, Tiéndrébéogo G, Singleton R. Social representations of mother-to-child transmission of HIV and its prevention in narratives by young Africans from five countries, 1997-2014: Implications for communication. Soc Sci Med 2018; 211:234-242. [PMID: 29966818 DOI: 10.1016/j.socscimed.2018.06.006] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/04/2018] [Revised: 06/13/2018] [Accepted: 06/14/2018] [Indexed: 12/11/2022]
Abstract
International recommendations related to the prevention of mother-to-child transmission (PMTCT) of HIV have evolved rapidly over time; recommendations have also varied contextually in line with local constraints and national policies. This study examines how young Africans made sense of mother-to-child transmission (MTCT) and PMTCT and related barriers and facilitators between 1997 and 2014 in the context of these complex and changing recommendations. It uses a distinctive data source: 1343 creative narratives submitted to HIV-themed scriptwriting competitions by young people aged 10-24 from 5 African countries (Senegal, Burkina Faso, Nigeria, Kenya, and Swaziland) between 1997 and 2014. The study triangulates between analysis of quantifiable characteristics of the narratives, thematic qualitative analysis, and narrative-based approaches. MTCT occurs in 8% of the narratives (108), while it is prevented in 5% (65). Narratives differ according to whether they depict MTCT or PMTCT (or, rarely, both), evolve over time, and show cross-national thematic variation. In the aggregate, representations shift in line with increased access to testing and antiretroviral medications, with PMTCT narratives becoming more frequent and MTCT narratives becoming more hopeful as diagnosis becomes the gateway to ART access. However, storylines of intergenerational tragedy in which MTCT is depicted as inevitable persist through 2014. Alongside cross-national differences in theme and tone, narratives from higher prevalence Swaziland and Kenya situate MTCT/PMTCT more centrally within descriptions of life with HIV. Findings illustrate the need to improve communication about PMTCT, reframing negative cultural narratives to reflect the full promise of developments of the past decade and a half.

J Med Virol 2018; 90:1210-1221. [PMID: 29574774 DOI: 10.1002/jmv.25072] [Citation(s) in RCA: 15] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/04/2017] [Accepted: 03/15/2018] [Indexed: 12/18/2022]
Abstract
A rapidly increasing number of HIV-1 infections have been identified among men who have sex with men (MSM) in Fujian province of China since 2010. We aimed to investigate the causative factors underlying this surging epidemic. Using immunoassays for HIV-1 diagnosis and phylogenetic analysis for viral genotyping, we found that the number of MSM infections doubled from 171 in 2011 to 340 in 2013 with a significantly increased prevalent rate from 4.1% to 5.2%. Majority of these increased infections took place in Fuzhou, Xiamen, and Quanzhou, three large cities in Fujian, mainly among youth, unemployed, business, and well-educated MSMs. Phylogenetic analysis revealed three major HIV-1 genotypes including CRF01_AE, CRF07_BC, and B/B' yet the surging MSM infections were primarily associated with the rapid sexual spread of CRF07_BC in addition to CRF01_AE. In particular, there was a significant proportional expansion of CRF07_BC infections among recently infected MSMs from 19% in 2012 to 41.9% in 2013. This increase was accompanied by emergence of complex patterns of viral recombination including multiple hybrid variants derived from CRF01_AE and CRF07_BC. Full-genome analysis indicated that CRF07_BC in Fujian was likely originated from similar strains previously found among IDUs in Yunnan province but with unique recombination break points. Our findings indicated that HIV-1 CRF07_BC has adapted for rapid sexual transmission, resulting in the surging HIV-1 epidemic and the emergence of new recombinant strains among MSMs in Fujian. Our findings have implications to vaccine and passive immunization trials in Fujian with emphasis on the induction of cross-subtype protective immunity.

Joshi RK, Mehendale SM. Can we replace HIV sentinel surveillance platform with prevention of parent-to-child transmission (PPTCT) program data to assess HIV burden and trends in India? Trans R Soc Trop Med Hyg 2017; 110:393-9. [PMID: 27496513 DOI: 10.1093/trstmh/trw045] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/06/2016] [Accepted: 06/15/2016] [Indexed: 11/13/2022] Open
Abstract
BACKGROUND Estimates of HIV burden in India are based on HIV sentinel surveillance (HSS), which has limitations such as insufficient sample size for district level analysis and ethical concerns. We analysed prevention of parent-to-child transmission (PPTCT) program data, for its suitability for HIV surveillance in India. METHODS Correlation and differences in ante-natal clinic (ANC) attendees' HIV prevalence from the last four rounds of HSS (2007-2012) and PPTCT data for the corresponding years were analysed at national, state and district levels. Sensitivity and region wise analysis were also done. RESULTS The PPTCT program covered a higher number of districts and ANC attendees than HSS. Correlation of HIV prevalence from PPTCT data with HSS was high (0.99) at national level, moderate (0.66-0.86) at state level, and low (0.43-0.62) at district level. HIV prevalence levels from HSS were generally higher than those from PPTCT data. As the coverage of PPTCT program and HSS improved, the differences between HIV prevalence from these two data sources increased. Sensitivity analysis showed significant differences in ANC attendees' HIV prevalence from HSS and PPTCT, even among districts with high HIV test uptake level in PPTCT program. CONCLUSIONS PPTCT program data can be utilised for HIV surveillance in India as it has better coverage and will avoid ethical issues and expenditures related to HSS.

Monitoring HIV Epidemic in Pregnant Women: Are the Current Measures Enough? JOURNAL OF SEXUALLY TRANSMITTED DISEASES 2015; 2015:194831. [PMID: 26316980 PMCID: PMC4437413 DOI: 10.1155/2015/194831] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/14/2014] [Revised: 11/01/2014] [Accepted: 12/29/2014] [Indexed: 12/05/2022]
Abstract
Introduction. Burden of HIV in pregnant women follows overall epidemic in India. Hence, it is imperative that prevalence calculations in this group be accurate. The present study was carried out to determine prevalence of HIV in pregnant women attending our hospital, to determine trend of HIV infection and to compare our results with reported prevalence. Methods. All pregnant women are routinely counselled for HIV testing using opt-out strategy. Year-wise positivity and trend were determined in these patients over a period of five years. The positivity in different age groups was determined. Results. 31,609 women were tested of which 279 (0.88%) were positive. Positivity showed a declining trend over study period and significant quadratic trend (biphasic, P < 0.05) was observed. The positivity in older age group ≥35 years (1.64%) was significantly more than younger age groups (0.76% in 15–24-year and 0.94% in 25–34-year age group) (P = 0.0052). Conclusion. A significant decline in HIV positivity was seen over the study period. Taking into account heterogeneous nature of HIV epidemic even within the same district, analysis at local levels especially using the prevention of parent to child transmission of HIV program data is critical for HIV programming and resource allocation.
