Background Botswana is close to reaching the UNAIDS “90-90-90” HIV testing, antiretroviral treatment (ART), and viral suppression goals. We sought determine incidence in this setting with both high prevalence ART coverage. Methods used a cross-sectional approach assessing incidence. A random, population-based sample of adults age 16–64 years was enrolled 30 rural peri-urban communities as part Combination Prevention Project (BCPP), from October 2013 –November 2015. Data samples baseline...

HIV-1 RNA load is the best biological predictor of HIV transmission and treatment response. The rate virologic suppression among key subpopulations can guide prevention programs.The Botswana Combination Prevention Project performed a population-based household survey adults in 30 communities Botswana. Data collected included knowledge HIV-positive status, antiretroviral therapy (ART) coverage, (HIV-1 ≤400 copies per milliliter). Individuals aged 16-29 years were considered young adults.Among...

Abstract Background Phylogenetic mapping of HIV-1 lineages circulating across defined geographical locations is promising for better understanding HIV transmission networks to design optimal prevention interventions. Methods We obtained near full-length genome sequences from people living with (PLWH), including participants on antiretroviral treatment in the Botswana Combination Prevention Project, conducted 30 communities 2013–2018. relationships among viral were estimated by maximum...

Introduction Non-citizens often face barriers to HIV care and treatment. Quantifying knowledge of positive status antiretroviral therapy (ART) coverage among non-citizens in a high HIV-prevalence country like Botswana that is close achieving UNAIDS "90-90-90" targets may expose important gaps universal testing Methods The Combination Prevention Project (BCPP) pair-matched cluster-randomized trial evaluating the impact prevention interventions on incidence 30 rural or peri-urban communities....

Additional strategies are needed to prevent and treat tuberculosis (TB). Although vitamin D may have antimycobacterial effects, it is unknown whether low status confers a risk for active TB in African children. This case-control study assessed serum 25-hydroxyvitamin (25(OH)D) concentration children with without Gaborone, Botswana. A total of 80 under 2 years old TB, seen at hospitals clinics the greater Gaborone area between September 2010 November 2012, were enrolled. Of these, 39 cases...

We describe rotavirus testing and clinical characteristics for children admitted with acute gastroenteritis during Botswana's 2011 season. The season extended from June to October rotavirus-specific case fatality being 2.8%. Using molecular as reference, the immunochromatographic test had a sensitivity of 76.5% specificity 68.0%. Rotavirus vaccine may significantly reduce childhood morbidity mortality in Botswana.

Background: Adolescents and young adults account for more than one-third of incident Human Immunodeficiency Virus (HIV) infections globally. Understanding sexual practices this high-risk group is critical in designing HIV targeted prevention programming. Objectives: To describe self-reported risky adolescents aged 16–24 years from 30 Botswana communities. Methods: Cross-sectional, age at debut; number partners; condom alcohol use during sex; intergenerational transactional sex data were...

Abstract Background Human immunodeficiency virus 1 (HIV-1) antiretroviral therapy (ART) alters hormonal contraceptive levels delivered via intravaginal ring (IVR) in a regimen-specific manner. We explored the role of IVR on vaginal microbial communities, short chain fatty acids (SCFAs), HIV shedding, and effect microbes hormone concentrations cisgender women with (WWH).

Cervical cancer is a common worldwide, with > 85% of deaths occurring in Lower- and Middle-Income Countries where resources for screening programs are limited. Women living HIV (WLHIV) at increased risk. HPV test-and-treat strategy women offered ablative treatment the cervix to reduce risk invasive cancer. WLHIV tend have more extensive cervical lesions, necessitating specialised surgical treatments.
