Background: Standard two-step HIV testing is limited by poor return-for-results rates and misses high-risk individuals who do not access conventional testing facilities.
Methods: We describe a community-based rapid HIV testing programme in which homeless and marginally housed adults recruited from shelters, free meal programmes and single room occupancy hotels in San Francisco received OraQuick Rapid HIV-1 Antibody testing (OraSure Technologies, Bethlehem, PA, USA).
Results: Over 8 months, 1614 adults were invited to participate and 1213 (75.2%) underwent testing. HIV seroprevalence was 15.4% (187 of 1213 individuals) overall and 3.5% (37 of 1063) amongst high-risk individuals reporting no previous testing, a prior negative test, or previous testing without result disclosure. All 1213 participants received their results. Of 30 newly diagnosed persons who received confirmatory results, 26 (86.7%) reported at least one contact with a primary healthcare provider in the 6 months following diagnosis.
Conclusions: We conclude that community-based rapid testing is feasible, acceptable and effective based on the numbers of high-risk persons tested over a short period, the participation rate, the prevalence of new infection, the rate of result disclosure, and the proportion linked to care.

Background: Cognitive impairment is a growing concern in Southeast Asian populations, where the burden of cerebrovascular disease (CeVD) is high. Currently, there is no point-based scoring system for identifying cognitive impairment in these populations.
Objective: To develop and validate a simple point-based Cognitive Impairment Scoring System (CISS) for identifying individuals with cognitive impairment no dementia (CIND) and concomitant CeVD in Southeast Asian populations.

Cholera has remained a persistent public health challenge in Zambia since the country's first reported outbreak in 1977. The recent outbreak, which began in October 2023 and is ongoing as of June 2024, is the most severe in Zambia's history and part of the larger 2022-2024 Southern Africa cholera outbreak, which has affected multiple countries in the region. This article describes the implementation of the integrated community strategy for cholera control (ICSCC) in three districts of the Copperbelt Province during this outbreak.

Despite the necessity of improved nutrition for these groups, some members do not fully meet their recommended daily micronutrient needs, a challenge exacerbated by different socioeconomic, cultural, and communal constraints resulting in malnutrition. Iron deficiency anaemia is a major concern among children and mothers, especially in pastoralist communities, due to poor nutrition and other related factors.
