This guideline provides updated, evidence-informed guidance on the percentage of total fat in the diet to reduce the risk of unhealthy weight gain.
This guideline is intended for a wide audience involved in the development, design and implementation of policies and programmes in nutrition and pub...lic health. This guideline includes a recommended level of total fat intake which can be used by policy-makers and programme managers to address various aspects of dietary fat in their populations through a range of policy actions and public health interventions.
The guidance in this guideline replaces previous WHO guidance on total fat intake, including that from the 1989 WHO Study Group on Diet, Nutrition and the Prevention of Chronic Diseases and the 2002 Joint WHO/FAO Expert Consultation on Diet, Nutrition and the Prevention of Chronic Diseases. The guidance in this guideline should be considered in the context of that from other WHO guidelines on healthy diets.

HIV testing programmes need to ensure that all clients who test for HIV are provided with correct diagnoses. The accuracy of HIV testing is critical to prevent misdiagnosis, as the consequences of giving an incorrect test result can be serious for clients, HIV testing services, HIV programmes and pu...blic health.
With the evolution of global HIV epidemiology, HIV testing approaches must also evolve to maintain accuracy and efficiency in population-level diagnosis. Reports suggest that misdiagnosis of HIV status may occur when suboptimal testing algorithms and out-of-date testing strategies are used. As a result of changing epidemiology and declining HIV positivity in testing, WHO recommends all countries use a standard three-test strategy to ensure a PPV of at least 99%, minimizing false-positive misdiagnosis. The WHO-recommended HIV testing strategy, along with quality assurance measures such as retesting to verify a positive diagnosis prior to initiation of HIV treatment, is cost-effective as it prevents misdiagnosis and unnecessary initiation of costly lifelong treatment.
This implementation guide provides practical advice on switching to a three-test strategy and instituting other measures that can help national HIV programmes deliver high-quality, accurate HIV testing services and ensure that misdiagnosis is minimized.

Climate change is one of the biggest crises of our time. Climate threats range from higher temperatures, heavy rainfalls and floods, erratic precipitation, droughts, desertification, and land degradation. This has negative implications on the quality and quantity of natural resources, such as land a...nd water, agricultural productivity, rural livelihood options, food prices, and nutrition security, particularly when there is a lack of adaptation capacities and preparedness measures (Pacillo, 2024). Farmers are at the forefront of the climate crisis where their livelihoods are being jeopardized, and they are faced with many challenges to secure water, energy, and agriculture inputs, and maintain agriculture productivity. This heightens the risk of competition over natural resources and aggravates grievances and structural inequalities related to land rights and ownership as well as land access, management, and governance. In Africa, land-related issues are among the triggers of many violent disputes (Medina et al, 2024). For instance, communal violence in Nigeria and Sudan is tied to competition over scarce fertile land and poor resource governance (Bruce and Bourdeaux, 2013).

For thousands of years, humans have been using wildlife for commercial and subsistence purposes. Wildlife trade takes place at local, national and international levels, with different forms of wildlife, such as live animals, partly processed products and finished products. Wildlife is a vital source... of safe and nutritious food, clothing, medicine, and other products, in addition to having religious and cultural value. Wildlife trade also contributes to livelihoods, income generation and overall economic development.
However, wildlife trade can have detrimental effects on species conservation, depleting natural resources, impoverishing biodiversity and degrading ecosystems (Morton et al., 2021). Wildlife trade, whether legal or illegal, regulated or unregulated, can pose threats to animal health and welfare. It also presents opportunities for zoonotic pathogens to spill over between wildlife and domestic animals, and for diseases to emerge with serious consequences for public or animal health and profound economic impacts (IPBES, 2020; Swift et al., 2007; Smith et al., 2009; Gortazar et al., 2014; Stephen, 2021; Stephen et al., 2022; FAO, 2020). The risk of pathogen spillover and disease emergence is amplified with increased interaction between humans, wildlife and domestic animals. The risk of pathogen spillover has also been exacerbated by climate change, intensified agriculture and livestock production, deforestation, and other land-use changes. Wildlife trade is also a risk to ecosystem biodiversity via the introduction of invasive species (Wikramanayake et al., 2021). Therefore, increased effort must be put into understanding the potential consequences of the wildlife trade, mapping and analysing the adjacent risks, and implementing strategies to manage those risks. Reducing wildlife-trade risks not only helps to limit disease but also minimises the negative effects of invasive species. Between 1960 and 2021, invasive alien species caused estimated cumulative damage of around 116 billion euros across 39 countries in the European Union alone, despite strict import regulations (Haubrock et al., 2021). The effect of invasive species is extremely apparent.

This fourth annual report monitors global progress towards the 2023 target for global elimination of industrially produced trans-fatty acids (TFA), highlighting achievements during the past year (October 2021 – September 2022). Countries are responding to the World Health Organization (WHO) call t...o action by putting into place best-practice TFA policies. Mandatory TFA policies are currently in effect for 3.4 billion people in 60 countries (43% of the world population); of these, 43 countries have best-practice policies in effect, covering 2.8 billion people (36% of the world population).
Over the past year, several additional countries took action to eliminate industrially produced TFA: best-practice policies came into effect in India in January 2022, Uruguay in May 2022 and Oman in July 2022. Best-practice policies were passed in Bangladesh in November 2021 (to come into effect in December 2022) and in Ukraine in September 2020 (to come into effect in October 2023), best-practice TFA policies are projected to pass soon in Mexico, Nigeria and Sri Lanka.

In 2015, the United Nations set important targets to reduce premature
cardiovascular disease (CVD) deaths by 33% by 2030. Africa disproportionately
bears the brunt of CVD burden and has one of the highest risks of dying
from non-communicable diseases (NCDs) worldwide. There is currently
an epide...miological transition on the continent, where NCDs is projected
to outpace communicable diseases within the current decade. Unchecked
increases in CVD risk factors have contributed to the growing burden of three
major CVDs—hypertension, cardiomyopathies, and atherosclerotic diseasesleading to devastating rates of stroke and heart failure. The highest age
standardized disability-adjusted life years (DALYs) due to hypertensive heart
disease (HHD) were recorded in Africa. The contributory causes of heart failure
are changing—whilst HHD and cardiomyopathies still dominate, ischemic
heart disease is rapidly becoming a significant contributor, whilst rheumatic
heart disease (RHD) has shown a gradual decline. In a continent where health
systems are traditionally geared toward addressing communicable diseases,
several gaps exist to adequately meet the growing demand imposed by CVDs.
Among these, high-quality research to inform interventions, underfunded
health systems with high out-of-pocket costs, limited accessibility and
affordability of essential medicines, CVD preventive services, and skill
shortages. Overall, the African continent progress toward a third reduction
in premature mortality come 2030 is lagging behind. More can be done in
the arena of effective policy implementation for risk factor reduction and
CVD prevention, increasing health financing and focusing on strengthening
primary health care services for prevention and treatment of CVDs, whilst
ensuring availability and affordability of quality medicines. Further, investing
in systematic country data collection and research outputs will improve the accuracy of the burden of disease data and inform policy adoption on
interventions. This review summarizes the current CVD burden, important
gaps in cardiovascular medicine in Africa, and further highlights priority
areas where efforts could be intensified in the next decade with potential
to improve the current rate of progress toward achieving a 33% reduction
in CVD mortality.
