Introduction: Paediatric tuberculosis (TB) underdiagnosis is a critical concern. The INPUT stepped-wedge cluster-randomised trial assessed the impact of integrating child TB services into child healthcare on TB case detection among children under age 5 years.

Methods: We compared the standard of care, providing TB care in specific TB clinics (control phase), with the Catalysing Paediatric TB Innovations (CaP-TB) intervention, integrating TB services across all child health services (intervention phase).

Mass testing with antigen-detecting rapid diagnostic tests (Ag-RDT), including testing of asymptomatic individuals, is expected to improve the identification of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infections. Mass testing was offered at large gatherings to determine the SARS-CoV-2 case detection rate and the acceptance and cost of implementing this community testing strategy. In 49 high-attendance venues in Kiambu County, Kenya, from June to September 2022, individuals 2 years and older were offered coronavirus disease 2019 (COVID-19) testing, vaccination, and participation in a survey.

Background: Children under age five years, particularly those living with HIV (CLHIV), are at risk for rapid progression of tuberculosis (TB). We aimed to describe TB clinical presentations, diagnostic pathways and treatment outcomes in CLHIV compared to children without HIV in Cameroon and Kenya.

Methods: This sub-analysis of a cluster-randomized trial evaluating the integration of pediatric TB services from May 2019 to March 2021 enrolled children age < 5 years with TB.

Despite large numbers of patients accessing antiretroviral treatment (ART) in Kenya, few studies have explored factors associated with virologic failure in Western Kenya, specifically. We undertook a study in Homa Bay County, Kenya to assess the extent of virologic treatment failure and factors associated with it. This was an observational retrospective study conducted from September 2020 to January 2021.
