14 July 2021 This article is part of a series of explainers on vaccine development and distribution. Learn more about vaccines – from how they work and how they’re made to ensuring safety and equitable access – in WHO’s Vaccines Explained series.
COVID-19 vaccines have proven to be safe, ...effective and life-saving. Like all vaccines, they do not fully protect everyone who is vaccinated, and we do not yet know how well they can prevent people from transmitting the virus to others. So as well as getting vaccinated, we must also continue with other measures to fight the pandemic.

To examine how health aid is spent and channelled, including the distribution of resources across countries and between
subsectors. Our aim was to complement the many qualitative critiques of health aid with a quantitative review and to provide insights on the level of development assistance availa...ble to recipient countries to address their health and health development needs.

Most foreign aid comes in one of two forms: either we pay a person or an institution today in exchange for delivering some beneficial activity in the future, or we observe something bad happen to them and then give them support to recover from it. This kind of aid is simple to design and deliver,
b...ut in the former case has limits in how sharply it incentivizes success and effort from a range of actors and in the latter case leads to the inefficient and undignified “begging bowl” approach to humanitarian financing. In what follows, I identify a broad family of alternative approaches, which
can loosely be grouped together as “contractually contingent financing,” and explain why they are still relatively underused.

Activity Brief.Formative research revealed that gold miners in remote regions of Guyana viewed malaria as an unavoidable and minor risk compared to other dangers. Building on these insights, Breakthrough ACTION co-created the 'Lil Mosquito, Big Problem' (LMBP) social and behavioural change campaign,... which targeted miners in malaria-endemic areas (Regions 7 and 8). Adopting a human-centred design approach, the campaign collaborated with the Ministry of Health, mining organisations, and miners throughout its development. LMBP used visual, low-literacy materials featuring animated and live-action characters to raise awareness of the risks of malaria and encourage key behaviours such as timely testing, adhering to treatment and consistently using insecticide-treated nets. Launched in 2019 and scaled up until 2024, this multi-channel campaign aimed to change attitudes and improve malaria prevention in these hard-to-reach communities.

Vector control, alongside case management, remains the most effective approach to controlling and eliminating malaria. Key interventions, such as indoor residual spraying (IRS) and long-lasting insecticidal nets (LLINs), have significantly reduced malaria transmission in many African countries. This... has enabled some countries to transition from the control phase to the elimination phase.

Thematic brief. Climate change and malaria are two defining challenges of our generation. Both affect disproportionately the
poorest and the most vulnerable, especially in Africa, and may further jeopardize human wellbeing in the future

Integrated Outbreak Analytics (IOA) applies a multidisciplinary approach to understanding outbreak dynamics and to inform outbreak response. It aims to drive comprehensive, accountable, and effective public health and clinical strategies by enabling communities, and national and subnational health a...uthorities to use data for operational decision-making. IOA embraces a holistic perspective of outbreak dynamics throughout: from the trigger questions to the data that are collected or accessed, to the interpretation of results and the recommendations that follow. In addition, IOA promotes co-development and monitoring of evidence informed actions.
The IOA toolkit aims to provide a clear understanding of IOA and highlight the importance of using an integrated, holistic approach to manage outbreak responses. It provides step-by-step guidance for setting up IOA and putting IOA principles into action. Finally, this toolkit provides guidance on applying IOA in humanitarian and emergency contexts, offering a practical and adaptable approach to informing public health emergency responses.
Developed based on the model from the Democratic Republic of the Congo (DRC), its creation involved extensive consultation with experts experienced in IOA applications. The toolkit was piloted in Tanganyika Province, DRC, as well as Somalia and Sudan, demonstrating its adaptability to diverse emergency scenarios. It builds upon an existing array of tools, templates, reports, case studies, animations, and publications used by stakeholders in diverse contexts.

This guidance synthesizes current evidence on dengue laboratory testing and diagnostics and provides practical recommendations for laboratories, clinicians, public health officials, and programme managers involved in dengue diagnosis, surveillance, and control, in the context of the global emergency.... It includes a diagnostic algorithm for suspected cases, outlining appropriate testing methods based on days post symptom onset.

Drawing on the World Health Organization’s package of NCD best buys, the report demonstrates how these evidence-based measures can help countries reduce premature deaths, strengthen health systems, and advance progress towards the Sustainable Development Goals. It provides policymakers, donors, ad...vocates, and partners with a clear economic and social rationale for scaling up implementation of proven solutions. By framing NCD prevention and control as both a health and development priority, the report offers a roadmap for action that delivers benefits across populations, economies, and generations. The evidence is clear: investing in WHO’s best buys is not only possible—it is imperative. The time to act is now.

Diabetes mellitus (DM) is a global epidemic with significant morbidity. Diabetic
retinopathy (DR) is the specific microvascular complication of DM and affects 1 in 3 persons with DM. DR remains a leading cause of vision loss in working adult populations. Patients with severe levels of DR are report...ed to have poorer quality of life and reduced levels of physical, emotional, and social well-being, and they utilize more health care resources.
Epidemiological studies and clinical trials have shown that optimal control of blood glucose, blood pressure, and blood lipids can reduce the risk of developing retinopathy and slow its progression. Timely treatment with laser photocoagulation, and increasingly, the appropriate use of intraocular administration of vascular endothelial growth factor (VEGF) inhibitors can prevent visual loss in vision- threatening retinopathy, particularly diabetic macular edema (DME). Since visual loss may not be present in the earlier stages of retinopathy, regular screening of persons with diabetes is essential to enable early intervention.

The guidelines presented in this document are designed to provide a useful resource for healthcare professionals involved in clinical case management. They were developed taking into consideration services provided at different levels within the health system and resources available. These guideline...s are intended to standardize care at both tertiary and secondary levels of service delivery across different socio economic stratifications of our society.
