Community engagement for vaccine delivery in low- and middle-income countries and humanitarian settings
Vaccination is a critical public health intervention in humanitarian and low- and middle-income country (LMIC) settings, where populations face heightened risks of vaccine-preventable diseases. Community Engagement (CE) offers a pathway to address challenges related to local ownership, trust, and acceptance, yet its effectiveness in these contexts remain underexplored. We conducted an umbrella scoping review of published reviews to synthesise evi…
Real-time analytical insights for disease surveillance and response during the severe drought and food security crisis, Somalia 2022–2023
BACKGROUND: Decades of conflict, epidemics, and climatic shocks have severely weakened Somalia's health system. The failure of five consecutive rainy seasons in 2022-2023 led to the longest and most severe drought in recent history, resulting in an unprecedented nutrition and food security crisis. These conditions have heightened the risk of disease epidemics, particularly cholera and measles. To assess the effect of interventions on disease tran…
Community-based mortality surveillance among internally displaced vulnerable populations in Banadir region, Somalia, 2022–2023
Somalia faces a severe humanitarian crisis driven by conflict, drought, and rising food prices, straining its fragile health system. Internally displaced persons (IDPs) suffer high mortality rates, yet data on causes of death remain limited. This study integrates verbal autopsy (VA) with community-based surveillance (CBS) to identify mortality causes in IDP populations. A hybrid retrospective-prospective mortality surveillance study was conducted…
A community-based contact isolation strategy to reduce the spread of Ebola virus disease
INTRODUCTION: Despite tremendous progress in the development of diagnostics, vaccines and therapeutics for Ebola virus disease (EVD), challenges remain in the implementation of holistic strategies to rapidly curtail outbreaks. We investigated the effectiveness of a community-based contact isolation strategy to limit the spread of the disease in the Democratic Republic of Congo (DRC). METHODS: We did a quasi-experimental comparison study. Eligible…
Investing in preparedness for rapid detection and control of epidemics
The 2014–2016 West Africa Ebola Virus Disease (EVD) Epidemic devastated Guinea’s health system and constituted a public health emergency of international concern. Following the crisis, Guinea invested in the establishment of basic health system reforms and crucial legal instruments for strengthening national health security in line with the WHO’s recommendations for ensuring better preparedness for (and, therefore, a response to) health emergenci…
High levels of mortality, malnutrition, and measles, among recently-displaced Somali refugees in Dagahaley camp, Dadaab refugee camp complex, Kenya, 2011
We report high death rates and prevalence of malnutrition among this population, reflecting at least a partial failure of the various humanitarian and governmental actors to adequately safeguard the welfare of this population. An outbreak of measles and long delays before registration should not have occurred. The recommendations for measles vaccination among crisis-affected populations should be revised to take into account the epidemiologic con…
Violence against civilians and access to health care in North Kivu, Democratic Republic of Congo
Our results show the impact of the ongoing war on these civilian populations: one third of deaths were violent in two sites, individuals are frequently subjected to violence, and displacements and theft are common. While humanitarian aid may have had a positive impact on disease mortality and access to care, the population remains exposed to extremely high levels of violence
Equity in community health insurance schemes
INTRODUCTION: Community health insurance (CHI) schemes are growing in importance in low-income settings, where health systems based on user fees have resulted in significant barriers to care for the poorest members of communities. They increase revenue, access and financial protection, but concerns have been expressed about the equity of such schemes and their ability to reach the poorest. Few programmes routinely evaluate equity impacts, even th…
