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.

Background: Peripheral artery disease is a growing public health problem. We aimed to estimate the global disease burden of peripheral artery disease, its risk factors, and temporospatial trends to inform policy and public measures.
Methods: Data on peripheral artery disease were modelled using the... Global Burden of Disease, Injuries, and Risk Factors Study (GBD) 2019 database. Prevalence, disability-adjusted life years (DALYs), and mortality estimates of peripheral artery disease were extracted from GBD 2019. Total DALYs and age-standardised DALY rate of peripheral artery disease attributed to modifiable risk factors were also assessed.

Recommendations on contraceptive methods used by
women at high risk of HIV
This summary covers the preventive approach to breast cancer control and includes prophylactic medications, prophylactic surgery and lifestyle modifications for breast cancer prevention. Health professional training and individual risk assessments and counseling are also discussed.
The Generic All-Hazards Risk Assessment and Planning Tool for Mass Gathering Events (“All-Hazards MG RA Tool”) aims to support Member States and mass gathering events organizers.
The tool is based on the principles of the World Health Organization’s Strategic Toolkit for Assessing Risk (STA...R) as well as lessons learned identified from the COVID-19 Risk Assessment Tool for Mass Gatherings. The purpose of the All-Hazards Mass Gatherings Risk Assessment tool is to identify hazards related to the event, assess and quantify the overall level of risk, identify and account for precautionary measures that may reduce the risk, making the event safer. The tool provides a systematic evidence-based approach to identifying and classifying priority risks; a description of the level of national preparedness and readiness to mitigate specific hazards; guidance on the implementation of a comprehensive and strategic risk assessment to inform preparedness and response plans ahead of the mass gathering; and an estimated assessment of the host country capacity to identify and respond to potential negative health impacts.

Policy Note #4: Myanmar Health Systems in Transition Policy Notes Series
Protecting people from financial hardship when they fall ill is one of the two key elements of universal health coverage (UHC). In practice, this means that the majority of health care costs have to be met from government ...revenues so that services are provided free or with a small affordable co-payment. The alternative is to rely on pre-payment through some form of insurance, where risks are pooled across all contributors.
The challenge in Myanmar is that at present neither approach is functioning. Government spending is too low to meet people’s health needs and the proportion of the population covered by insurance is negligible. As a result, families face a stark choice in the event of serious illness: either defer treatment and face the consequences, or incur what can amount to catastrophic expenses and a downward spiral of disinvestment and poverty.

Background: Cardiovascular disease (CVD), mainly heart attack and stroke, is the
leading cause of premature mortality in low and middle income countries (LMICs).
Identifying and managing individuals at high risk of CVD is an important strategy to prevent and control CVD, in addition to multisector...al population-based interventions to reduce CVD risk factors in the entire population.
Methods: We describe key public health considerations in identifying and managing individuals at high risk of CVD in LMICs.
Results: A main objective of any strategy to identify individuals at high CVD risk is to maximize the number of CVD events averted while minimizing the numbers of
individuals needing treatment. Scores estimating the total risk of CVD (e.g. ten-year risk of fatal and non-fatal CVD) are available for LMICs, and are based on the main CVD risk factors (history of CVD, age, sex, tobacco use, blood pressure, blood cholesterol and diabetes status). Opportunistic screening of CVD risk factors enables identification of persons with high CVD risk, but this strategy can be widely applied in low resource settings only if cost effective interventions are used (e.g. the WHO Package of Essential NCD interventions for primary health care in low resource settings package) and if treatment (generally for years) can be sustained, including continued availability ofaffordable medications and funding mechanisms that allow people to purchase medications without impoverishing them (e.g. universal access to health care). Thisalso emphasises the need to re-orient health systems in LMICs towards chronic diseases management.
Conclusion: The large burden of CVD in LMICs and the fact that persons with high
CVD can be identified and managed along cost-effective interventions mean that
health systems need to be structured in a way that encourages patient registration, opportunistic screening of CVD risk factors, efficient procedures for the management of chronic conditions (e.g. task sharing) and provision of affordable treatment for those with high CVD risk. The focus needs to be in primary care because that is where most of the population can access health care and because CVD programmes can be run effectively at this level.

Interim guidanceAnnex to: Policy considerations for implementing a risk-based approach to international travel in the context of COVID-19, 2 July 2021
The technical note from the Global Task Force on Cholera Control (GTFCC) examines the risks and benefits of vaccinating pregnant women with WHO-prequalified oral cholera vaccines (OCVs) during mass vaccination campaigns. It highlights that three WHO-approved vaccines (Dukoral®, Shanchol™, and Euv...ichol®) offer sustained protection and a strong safety profile.
While these vaccines are not explicitly contraindicated for pregnant women, there is limited clinical data on their use during pregnancy. However, studies indicate that pregnant women with cholera face higher risks of fetal loss, stillbirth, and complications, especially if they experience severe dehydration. Some evidence suggests that vaccination can reduce cholera incidence in pregnant women and indirectly protect infants.
Although no controlled trials have focused on pregnant women, retrospective studies in Guinea and Zanzibar showed no significant increase in adverse pregnancy outcomes after OCV administration. The GTFCC concludes that the benefits of vaccination outweigh the risks, particularly in high-risk areas, and recommends including pregnant women in cholera vaccination campaigns while continuing to monitor safety data.

The document provides an overview of malaria in the Americas, describing its transmission, symptoms, vulnerable populations, and regional trends, while highlighting prevention strategies and the efforts of PAHO/WHO and member states to eliminate the disease by 2020.
Relapsing malaria caused by Plasmodium vivax parasites poses a significant challenge to global malaria elimination efforts. About one third of the population remains at risk of contracting P. vivax malaria, and 85% of P. vivax infections stem from reactivated latent parasites, leading to chronic ana...emia and increased morbidity and mortality. In addition to diagnostic tools that can detect the acute, blood-stage of P. vivax, new tools are needed to detect the dormant infections before they reactivate and contribute to morbidity and onwards transmission
