The purpose of cancer screening tests is to detect pre-cancer or early-stage cancer in asymptomatic individuals so that timely diagnosis and early treatment can be offered, where this treatment can lead to better outcomes for some people.
The aim of a cancer screening programme is either to reduc...e mortality and morbidity in a population by early detection and early treatment of a cancer (for example, breast screening) or to reduce the incidence of a cancer by identifying and treating its precursors (such as cervical and colorectal screening).
This short guide is designed to be a quick reference that contains the important ideas about cancer screening. Readers should refer to other publications for comprehensive discussion and detailed guidance on cancer screening programmes.

Concentrations of the major greenhouse gases, CO2 , CH4 , and N2 O, continued to increase despite the temporary reduction in emissions in 2020 related to measures taken in response to COVID-19.
2020 was one of the three warmest years on record. The past six years, including 2020, have been the si...x warmest years on record. Temperatures reached 38.0 °C at Verkhoyansk, Russian Federation on 20 June, the highest recorded temperature anywhere north of the Arctic Circle.
The trend in sea-level rise is accelerating. In addition, ocean heat storage and acidification are increasing, diminishing the ocean’s capacity to moderate climate change.

Latin America and the Caribbean is characterized by a matrix of social inequality whose axes —such as
socioeconomic stratum, gender, stage in the life cycle, ethnicity and race, territory, disability, and immigration
status— create multiple, often concurrent, situations of exclusion and discri...mination. The coronavirus
disease (COVID-19) pandemic has exacerbated wide social gaps and it is no coincidence that Latin America
and the Caribbean is one of the regions in which the health and socioeconomic impacts of the pandemic have
been the most severe, which shows that the costs of inequality are unsustainable

The purpose of the WHO Manual for the Public Health Management of Chemical Incidents is to provide a comprehensive overview of the principles and roles of public health in the management of chemical incidents and emergencies. While this information is provided for each phase of the emergency cycle, ...including prevention, planning and preparedness, detection and alert, response and recovery, it is recognized that the management of chemical incidents and emergencies requires a multi-disciplinary and multi-sectoral approach and that the health sector may play an influencing, complementary or a leadership role at various stages of the management process. The target audience includes public health and environmental professionals, as well as any other person involved in the management of chemical incidents.
WHO and all those involved in the development of the publication hope that the publication will have wide application, especially in developing countries and countries with economies in transition, and that in the future the health sector will be better prepared to acknowledge and fulfill its roles and responsibilities in the management of chemical incidents and emergencies, thereby contributing to the prevention and mitigation of their health consequences.
The publication is also available in French: http://apps.who.int/iris/bitstream/handle/10665/246117/9789242598148-fre.pdf?sequence=1 and in Spanish: http://apps.who.int/iris/bitstream/handle/10665/246118/9789243598147-spa.pdf?sequence=1

The relative priority received by issues
in global health agendas is subjected to impressionistic
claims in the absence of objective methods of assessment
of priority. To build an approach for conducting structured
assessments of comparative priority health issues receive,
we expand the public ...arenas model (2021) and offer a
framework for future assessments of health issue priority
in global and national health agendas.

Rising levels of inflation, debt and macrofiscal tightening are putting expenditures on the social sectors including health under immense scrutiny. Already, there are worrying signs of reductions in social sector investments. However, even before the pandemic, evidence showed the significant returns... on investments in health equity and its social determinants. Emerging data and trends show that these potential returns have increased during the COVID-19 pandemic - investments in social determinants can mitigate widespread reductions in human capital and the increasing likelihood of costly syndemics, while promoting access to healthcare innovations that have thus far been inequitably distributed. Therefore, we argue that, despite immediate fiscal pressures, this is exactly the time to invest in health equity and its broader social determinants, as the returns on such investments have never been greater.

Africa’s health sector is facing an unprecedented financing crisis, driven by a sharp decline of 70% in Official Development Assistance (ODA) from 2021 to 2025 and deep-rooted structural vulnerabilities. This collapse is placing immense pressure on Africa’s already fragile health systems as ODA ...is seen as the backbone of critical health programs: pandemic preparedness, maternal and child health services, disease control programs are all at
risk, threatening Sustainable Development Goal 3 and Universal Health Coverage. Compounding this is Africa’s spiraling debt, with countries expected to service USD 81 billion by 2025—surpassing anticipated external financing inflows—further eroding fiscal space for health investments. Level of domestic resources is low. TThe Abuja Declaration of 2001, a pivotal commitment made by African Union (AU) member states, aimed to reverse this trend by pledging to allocate at least 15% of national budgets to the health sector. However, more than two decades later, only three countries—Rwanda, Botswana, and Cabo Verde—have
consistently met or exceeded this target (WHO, 2023). In contrast, over 30 AU member states remain well below the 10% benchmark, with some allocating as little as 5–7% of their national budgets to health.
In addition, only 16 (29%) of African countries currently have updated versions of National Health Development Plan (NHDP) supported by a National Health Financing Plan (NHFP). These two documents play a critical role in driving internal resource mobilisation. At the same time, public health emergencies are surging, rising 41%—from 152 in 2022 to
213 in 2024—exposing severe under-resourcing of health infrastructure and workforce. Recurring outbreaks (Mpox, Ebola, cholera, measles, Marburg…) alongside effects of climate change and humanitarian crises in Eastern DRC, the Sahel, and Sudan, are overwhelming systems stretched by chronic underfunding. The situation is worsened by Africa’s heavy dependency with over 90% of vaccines, medicines, and diagnostics being externally sourced—leaving countries vulnerable to global supply chain shocks. Health worker shortages persist, with only 2.3 professionals
per 1,000 people (below the WHO’s recommended 4.45), and fewer than 30% of systems are digitized, undermining disease surveillance and early warning. Without decisive action, Africa CDC projects the continent could reverse two decades of health progress, face 2 to 4 million additional preventable deaths annually, and a heightened risk of a pandemic emerging from within. Furthermore, 39 million more
Africans could be pushed into poverty by 2030 due to intertwined health and economic shocks. This is not just a sectoral crisis—it is an existential threat to Africa’s political, social, and economic resilience, and global stability. In response, African leaders, under Africa CDC’s stewardship, are advancing a comprehensive three-pillar strategy centered on domestic resource mobilization, innovative financing, and blended finance.

The Council was established in late 2020 by Dr Tedros Adhanom
Ghebreyesus (Director-General, WHO) to provide new economic thinking – reassessing how health and wellbeing are valued, produced and distributed across the economy. An all-female group of 10 distinguished economists and area experts, t...he Council has focused on reimagining how to put Health for All at the heart of government decision-making and private sector collaboration at regional, national and international levels.

In 2019, the Task Force on Fiscal Policy for Health concluded that taxes on tobacco, alcohol, and sugar-sweetened beverages were a highly effective but greatly underused policy tool to reduce consumption, save lives, and raise domestic resources. The Task Force estimated that if all countries increa...sed their excise taxes to raise prices by 50 percent, over 50 million premature deaths could be averted worldwide over the next 50 years while
raising over USD 20 trillion of additional revenue. Since the Task Force first convened, the world has faced a “polycrisis,” including a global pandemic, an economic recession, and the outbreak of wars in Europe and the Middle East. Against this backdrop, the world has also experienced prolonged health and fiscal crises. Health systems, weakened by the COVID-19 pandemic, lack sufficient financing to rebuild and respond to the surging noncommunicable diseases epidemic caused by uncontrolled risk factors such as tobacco, alcohol, and sugar consumption. Opportunities to raise domestic resources are limited and debt burdens have squeezed budgets. The period from 2019 to 2027 risks becoming a “lost decade” for health and social policies, with 110 countries facing little prospect of any
ability to raise government revenues beyond current levels. In this paper, we describe the current health and fiscal crises and review the contribution that health taxes could make in turning around this dire situation. We conclude that taxes on tobacco, alcohol, and
sugar-sweetened beverages are an ideal policy solution—good for the budget and good for health. These taxes are relatively quick to implement, and, unlike other taxes, do not put economic growth at risk—a vital benefit in the current era.

The objectives of this guideline are the same as those of the 2011 edition, namely to provide evidence-based normative guidance on interventions to improve adolescent morbidity and mortality by reducing the chances of early pregnancy and its resulting poor health outcomes. The specific objectives of... the guideline were to: 1. identify effective interventions to prevent early pregnancy by influencing factors such as early marriage, coerced sex, unsafe abortion, access to contraceptives and access to maternal health services by adolescents; and 2. provide an analytical framework for policy-makers and programme managers to use when selecting evidence-based interventions to prevent early pregnancy and negative health outcomes when they occur that are most appropriate for the needs of their countries and context. The recommendations and best practice statements described in this document aim to enable evidence-based decision-making with respect to preventing early pregnancy and poor reproductive outcomes among adolescents in low- and middle-income country contexts.
