From mission hospital to medical research hub
AIC Kijabe Hospital (AICKH) in Kenya started in 1915 as a small clinic serving the surrounding rural community. In recent decades, it has transformed into a large teaching hospital with growing expertise in healthcare research and training with grant support for large multi-institutional trials, integrated research instruction for students and residents, and more than 40 research projects launched and completed annually. Its progress is unusual d…
Improving HIV assisted partner services outcomes by eliciting additional partners after the initial encounter
Most assisted partner services (APS) programs elicit partners at the time of HIV diagnosis when index clients may be reluctant to name all partners. Little is known about the benefits of ongoing partner elicitation after the initial visit. We utilized data collected in an APS implementation study across 31 facilities in western Kenya from August 2019 to June 2022. HIV testing service providers offered APS to consenting female index clients and as…
Drought impacts and community adaptation
The Horn of Africa drylands (HAD) encompassing Kenya, Somalia, and Ethiopia, recently endured an unprecedented multi-year drought from 2020 to 2023, causing devastating impacts. This study investigates these impacts and the dynamics of human adaptation in response to the drought, comparing it to earlier drought events (i.e., 2016–2018) to identify key lessons. First, drought impact data—covering milk production, trekking distances to water source…
Shifting reasons for older men remaining uncircumcised
Voluntary medical male circumcision (VMMC) reduces men’s risk of acquiring Human immunodeficiency virus (HIV) through vaginal sex. However, VMMC uptake remains lowest among Kenyan men ages 25–39 years among whom the impact on reducing population-level HIV incidence was estimated to be greatest at the start of the study in 2014. We conducted a pre- and post-intervention survey as part of a cluster randomized controlled trial to determine the effec…
Uptake and acceptability of oral HIV self-testing in the context of assisted partner services in Western Kenya
Integrating HIV self-testing (HIVST) into assisted partner services (APS) has potential to increase identification of people with HIV in the community, but little is known about acceptability of HIVST among partners traced via APS. We assessed characteristics of APS partners testing with HIVST, and factors influencing HIVST uptake and acceptability in a cluster-randomized control trial on APS+HIVST. Using convergent parallel mixed-methods design,…
Integration of assisted partner services within Kenya’s national HIV testing services program
Assisted partner service (aPS) augments HIV case-finding among sex partners to individuals newly diagnosed with HIV. In 2016, aPS was incorporated into the national HIV testing services (HTS) program in Kenya. We evaluated the extent of, barriers to, and facilitators of aPS integration into HTS. We conducted semi-structured in-depth interviews (IDIs) with 32 stakeholders selected using purposive sampling at national, county, facility, and communi…
Mainstreaming forecast based action into national disaster risk management systems
Drought and food security crises heighten risks to lives and livelihoods in East Africa. In recent years, a shift towards acting in advance of such events has gained momentum, notably among the humanitarian and development community. This shift is premised on tools that link climate forecasts with pre-agreed actions and funding, known as Forecast-based Action (FbA), or anticipatory action more widely. While FbA approaches have been developed by a…

Rapid situational assessment of people who inject drugs (PWID) in Nairobi and coastal regions of Kenya
Compared to the national HIV prevalence of (4.9%), the results show that People Who Inject Drugs (PWIDs) are at particularly high risk of infection in Kenya and there is urgent need for intervention (KenPHIA, 2018). This study also showed clear evidence that 70% of PWIDs are primary school educated, engage in high risk injecting and sexual behaviors comprising sharing of injecting equipment, unprotected heterosexual and homosexual sex. Given that…
Projected effects of 1.5 °C and 2 °C global warming levels on the intra-seasonal rainfall characteristics over the Greater Horn of Africa
This study examines the effects of 1.5 °C and 2 °C global warming levels (GWLs) on intra-seasonal rainfall characteristics over the Greater Horn of Africa. The impacts are analysed based on the outputs of a 25-member regional multi-model ensemble from the Coordinated Regional Climate Downscaling Experiment project. The regional climate models were driven by Coupled Model Intercomparison Project Phase 5 Global Climate Models for historical and fut…
Projected climate over the Greater Horn of Africa under 1.5 °C and 2 °C global warming
We analyze the potential effect of global warming levels (GWLs) of 1.5 C and 2 C above pre-industrial levels (1861-1890) on mean temperature and precipitation as well as intra-seasonal precipitation extremes over the Greater Horn of Africa. We used a large, 25-member regional climate model ensemble from the Coordinated Regional Downscaling Experiment and show that, compared to the control period of 1971-2000, annual mean near-surface temperature …
Community perceptions and personal accounts of HIV discordance in rural western Kenya
Among HIV-discordant couples, the literature is sparse regarding issues related to stigma, relationships and coping. Objectives were to explore: 1) perceptions about discordant HIV status; 2) understanding of HIV discordancy; 3) effects of discordancy on couples; and 4) adaptation and coping strategies for discordant HIV status. A survey was administered to 202 members of heterosexual discordant couples in rural western Kenya. In addition, to und…
Teen pregnancy in rural western Kenya
Rates of teenage pregnancy remain high in sub-Saharan Africa. The KEMRI Health and Demographic Surveillance System provided the sampling frame for a survey. Analysis focused on 1,952 girls aged 13–19 years. Over a third (37.2%; n = 727) were sexually active and 23.3% (n = 454) had ever been pregnant. Adjusted odds of reporting a history of pregnancy were greater for older compared to younger teens, teens who were ever married or cohabiting compar…
