Introduction HIV Sentinel Surveillance (HSS) among pregnant women is a key indicator to estimate the HIV prevalence in the general population, as nearly 85% of HIV transmission in India is linked to the heterosexual route. Tracking the levels and trends of the HIV prevalence at state, regional, and district levels help to prioritize and facilitate a tailor-made intervention. Here, we analyze the region and district-wise levels and trends of HIV prevalence among pregnant women attending the antenatal clinics (ANC) from 2003 to 2019 in Tamil Nadu. Methods Eleven rounds of HSS data collected from pregnant women in Tamil Nadu, from 2003 to 2019 were analysed. Consistent sites were grouped into four geographical regions (North, Central, West and South), a total of 67 sites including 33 urban 31 rural, and 3 private sites. Chi-square trend test used to find linear trends and spatial analysis used to understand the geographical distribution of HIV prevalence over the years. Results In total, 2,77,444 blood samples were collected during HSS from 2003 to 2019. In 2019, the state HIV prevalence was 0.18 (95% CI: 0.13–0.23); region-wise prevalence was 0.21, 0.07, 0.32 and 0.12 in North, Central, West and South respectively. HIV prevalence in Tamil Nadu had significantly declined since 2003, which however, was not significant in all districts; with inter-district fluctuations. Conclusion HIV interventions have to be strengthened in the districts with inconsistent trends, specifically the West region. This requires a more detailed analysis of region-specific contextual factors associated with the transmission risk.

Background HIV Sentinel Surveillance among pregnant women attending antenatal care clinics, ANC-HSS, is used to estimate HIV prevalence among the general population. Despite the declining trend, HIV prevalence among the general population in Karnataka is still higher than the national average (0.22%), with a recent, noticeable stabilization. Demographic analysis on concentrated HIV infection among pregnant women could be potential indicators for targeted HIV interventions among general population as well as and prevention of parent to child transmission (PPTCT). Objectives To analyse the demographics of HIV-positive pregnant mothers in Karnataka, thereby identifying the most-at-risk populations (MARP) within the general population. Methods In total, 24800 eligible pregnant women aged 15–49 attending the ANC clinic for the first time during the surveillance period (Jan–Mar, 2017) were enrolled. Demographic data and blood samples were collected, recorded and tested for HIV. Age-specific factors associated with HIV prevalence, besides the demographics of the HIV positive pregnant women, were analysed to identify the MARP for targeted HIV interventions. Results Comprehensively, none of the demographic factors was significantly associated with HIV prevalence. Nevertheless, analysis of demographics, HIV test history and ART status of HIV-positive pregnant women reveals prominent prevalence patterns. The epidemic was majorly confined within young, less educated, primigravida and rural mothers of low economic status. Conclusion ANC-HSS is designed to estimate the HIV prevalence among general population at national, state and district levels and is not reflective of the concentrated epidemic confined to MARP. Identifying the disease pattern specific to MARP is essential for effective targeted interventions and disease management.

Background and Objectives: The purpose of this study was to analyze trends in HIV prevalence and risk factors associated with HIV infection among pregnant women attending antenatal clinics in Odisha State, India. Methods: Data were from the HIV Sentinel Surveillance (HSS) among pregnant women, a descriptive cross-sectional study using consecutive sampling method and conducted in India. Data and samples were collected from pregnant women attending select antenatal clinics that act as designated sentinel sites in Odisha State, India, during the three months surveillance period and in three surveillance years: 2013, 2015, and 2017. All eligible pregnant women aged between 15 and 49 years, attending the sentinel sites for the first time during the surveillance period, were included. Information on their socio-demographic characteristics and blood samples were also collected. Results: In total, 38,384 eligible pregnant women were included in the survey. Of these, 107 women were HIV positive, with an overall prevalence of 0.28%. HIV prevalence indicated a stabilizing trend between 2013 and 2017. However, pregnant women whose spouses were non-agricultural laborers, truck drivers, or migrants were significantly at higher risk of being infected. Likewise, HIV prevalence significantly increased over the years among pregnant women whose spouses were in the service sector (government or private). District-wise fluctuations in HIV prevalence was observed, with the district of Cuttack recording the highest prevalence among the districts. Conclusion and Global Health Implications: Women who are spouses of non-agricultural laborers, truck drivers or migrants need focused interventions, such as creating awareness on HIV and its prevention. Migration, due to poverty and its impact on sexually transmitted diseases among migrants from low and middle-income countries, have been documented globally. Single male migrant specific interventions are recommended to halt the disease progression among pregnant women and general population in Odisha, India.

Background: The proximity of Northeast India to the Golden Triangle facilitates easy accessibility to illicit drugs, resulting in a higher proportion of injecting drug users (IDUs) in the states of Northeast India. The estimated human immunodeficiency virus (HIV) prevalence among IDU in Manipur which is 1.43% is higher than that of the national figure. Objectives: The objectives of the study were to find the factors associated with HIV infection and correlate the association between HIV status and self-assessed risk to HIV among IDUs in Manipur. Methods: National Integrated Biological and Behavioral Surveillance (2014–2015) data were used for the study; all analyses done were weighted. In Manipur, information was collected from 1594 IDUs during the surveillance between 2014 and 2015 across four domains, namely Chandel (396), Imphal East (397), Thoubal (401), and Senapati (400). Chi-square test was performed to test the association between the independent and dependent variables. Multivariable logistic regression was performed to identify risk factors associated with HIV positivity. Results: Higher age, unsafe injecting practice, low education status, and low-income status were significantly (P < 0.05) associated with HIV infection among IDUs in Manipur. Self-assessed risk of HIV infection by IDU was significantly associated with HIV positivity. Conclusion: Interventions among IDUs in Manipur should focus on emphasizing safe injecting practices along with creating awareness on HIV prevention and management.

Severe Acute Respiratory Syndrome-Coronavirus-2 (SARS-CoV-2) is the causative etiology of ‘Corona Virus Disease-2019' (COVID-19); formerly referred as ‘novel-Coronavirus-2019'. It was originated in Wuhan city, Hubei province, China in early December 2019. The World Health Organization (WHO) declared it as ‘Public Health Emergency of International Concern' due to their rapid transmission and causing public and health-care-related casualties worldwide. This review provides an updated overview of COVID-19 (SARS-CoV-2), in comparison with the etiologies of the same group viz. SARS and MERS and also its future perspectives for planning appropriate strategies for prevention, control and treatment modalities to avert similar catastrophe in near future.

Background Avahan, the India AIDS Initiative, a large-scale HIV prevention program, using peer-mediated approaches and STI services, was implemented for high-risk groups for HIV in six states in India. This paper describes the assessment of the program among female sex workers (FSWs) in the southern state of Tamil Nadu. Methods An analytical framework based on the Avahan impact evaluation design was used. Routine program monitoring data, two rounds of cross-sectional biological and behavioural surveys among FSWs in 2006 (Round 1) and 2009 (Round 2) and quality assessments of clinical services for sexually transmitted infections (STIs) were used to assess trends in coverage, condom use and prevalence of STIs, HIV and their association with program exposure. Logistic regression analysis was used to examine trends in intermediate outcomes and their associations with intervention exposure. Results The Avahan program in Tamil Nadu was scaled up and achieved monthly reported coverage of 79% within four years of implementation. The cross-sectional survey data showed an increasing proportion of FSWs being reached by Avahan, 54% in Round 1 and 86% in Round 2 [AOR=4.7;p=0.001]. Quality assessments of STI clinical services showed consistent improvement in quality scores (3.0 in 2005 to 4.5 in 2008). Condom distribution by the program rose to cover all estimated commercial sex acts. Reported consistent condom use increased between Round 1 and Round 2 with occasional (72% to 93%; AOR=5.5; p=0.001) and regular clients (68% to 89%; AOR=4.3; p=0.001) while reactive syphilis serology declined significantly (9.7% to 2.2% AOR=0.2; p=0.001). HIV prevalence remained stable at 6.1% between rounds. There was a strong association between Avahan exposure and consistent condom use with commercial clients; however no association was seen with declines in STIs. Conclusions The Avahan program in Tamil Nadu achieved high coverage of FSWs, resulting in outcomes of improved condom use, declining syphilis and stabilizing HIV prevalence. These expected outcomes following the program logic model and declining HIV prevalence among general population groups suggest potential impact of high risk group interventions on HIV epidemic in Tamil Nadu.
