Air pollution is contamination of the indoor or outdoor environment by any chemical, physical or biological agent that modifies the natural characteristics of the atmosphere. Household combustion devices, motor vehicles, industrial facilities and forest fires are common sou...rces of air pollution. Pollutants of major public health concern include particulate matter, carbon monoxide, ozone, nitrogen dioxide and sulfur dioxide. Outdoor and indoor air pollution cause respiratory and other diseases and is an important source of morbidity and mortality.
Air pollution kills an estimated seven million people worldwide every year. WHO data shows that almost all of the global population (99%) breathe air that exceeds WHO guideline limits containing high levels of pollutants, with low- and middle-income countries suffering from the highest exposures. WHO is supporting countries to address air pollution.
From smog hanging over cities to smoke inside the home, air pollution poses a major threat to health and climate. The combined effects of ambient (outdoor) and household air pollution cause millions of premature deaths every year, largely as a result of increased mortality from stroke, heart disease, chronic obstructive pulmonary disease, lung cancer and acute respiratory infections.

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.

On Global Handwashing Day, WHO and UNICEF have released the first-ever global Guidelines on Hand Hygiene in Community Settings to support governments and practitioners in promoting effective hand hygiene outside health care – across households, public spaces and institutions. Framing hand hygiene ...as a public good and a government responsibility, the Guidelines translate evidence into ready-to-adopt actions that enable sustainable access to effective hygiene services. This will reduce diarrhoeal disease, acute respiratory infections and other preventable illnesses, strengthening routine public health where people live, work, visit and study, and emergency preparedness, including outbreaks like cholera.
Despite clear benefits, 1.7 billion people still lacked basic hand hygiene services at home in 2024, including 611 million with no facility at all. Meeting the 2030 target will require accelerated progress – about a doubling in the global rate, and much faster in specific settings (up to 11-fold in least-developed countries and 8-fold in fragile contexts). Hand hygiene remains one of the most cost-effective health investments, reducing diarrhoea by 30% and acute respiratory infections by 17%, with large, measurable gains for population health.
“Clean hands save lives, but results at scale require policy, financing and accountability,” said Dr Ruediger Krech, Director a.i, Department of Environment, Climate Change, One Health & Migration at the World Health Organization. “These Guidelines help countries move beyond fragmented projects to government-led systems that make soap, water, and conditions conducive to everyday hand hygiene the norm.”
“Children and young people pay the highest price when basic hygiene is out of reach,” said Cecilia Scharp, Director, Water Sanitation and Hygiene (WASH) Team, Programme Group, UNICEF. “These Guidelines provide practical steps to ensure facilities are accessible when they need to be – in homes, schools, markets, and transport hubs – so every child can learn, play and thrive with dignity.”

2023 is seeing intense heatwaves. According to a July 2023 briefing by the World Meteorological Association temperatures will frequently reach above 35–40°C in many places across the Mediterranean region, with temperatures in the Middle East and southeastern Türkiye reaching up to 45°C and, in ...North Africa, 44–49°C. April–May 2023 also saw temperature records broken across many parts of Asia, including Thailand, Laos and Myanmar.
The IPCC predicts that 420 million people will be exposed to extreme heat and heatwaves in the near future. Hundreds of thousands of people die from preventable heat-related causes each year, while temperature extremes and wildfires cause devastation to lives and livelihoods. According to the WMO, ‘heatwaves are amongst the deadliest natural hazards [and] heat is a rapidly growing health risk’.

Der Klimawandel verschärft die Treiber für Migration und Flucht
Zu den ohnehin bestehenden Gründen, die Menschen zum Verlassen ihrer Heimat zwingen, kommt der Klimawandel verschärfend hinzu. Schätzungen zur Rolle des Klimawandels sind wegen der Komplexität des Zusammenspiels verschiedener Mig...rations- oder Fluchtursachen äußerst schwierig. Die Vorhersagen über das mögliche Ausmaß von Migration infolge des Klimawandels gehen daher weit auseinander – bis zum Jahr 2050 könnten zwischen 25 und 700 Millionen Menschen davon betroffen sein (micle 2012).
