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 Reports suggest that misdiagnosis of HIV status may occur when suboptimal testing algorithms and out-of-date testing strategies are used.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.

Many features of the environment have been found to exert an important influence on cardiovascular disease (CVD) risk, progression, and severity. Changes in the environment due to migration to different geographic locations, modifications in lifestyle choices, and shifts in social policies and cultu...ral practices alter CVD risk, even in the absence of genetic changes. Nevertheless, the cumulative impact of the environment on CVD risk has been difficult to assess
and the mechanisms by which some environment factors influence CVD remain obscure. Human environments are complex; and their natural, social and personal domains are highly variable due to diversity in human ecosystems, evolutionary histories, social structures, and individual choices. Accumulating evidence supports the notion that ecological features such as the diurnal cycles of
light and day, sunlight exposure, seasons, and geographic characteristics of the natural environment such altitude, latitude and greenspaces are important determinants of cardiovascular health and CVD risk. In highly developed societies, the influence of the natural environment is moderated by the physical characteristics of the social environments such as the built environment
and pollution, as well as by socioeconomic status and social networks. These attributes of the
social environment shape lifestyle choices that significantly modify CVD risk. An understanding
of how different domains of the environment, individually and collectively, affect CVD risk could
lead to a better appraisal of CVD, and aid in the development of new preventive and therapeutic
strategies to limit the increasingly high global burden of heart disease and stroke.

About one fourth of the world’s population is estimated to have been infected with the tuberculosis (TB) bacilli, and about 5–10% of those infected develop TB disease in their lifetime. The risk for TB disease after infection depends on several factors, the most important being the person’s im...munological status. TB preventive treatment (TPT) given to people at highest risk of progressing from TB infection to disease remains a critical element to achieve the global targets of the End TB Strategy, as reiterated by the second UN High Level Meeting on TB in 2023. Delivering TPT effectively and safely necessitates a programmatic approach to implement a comprehensive package of interventions along a cascade of care: identifying individuals at highest risk, screening for TB and ruling out TB disease, testing for TB infection, and choosing the preventive treatment option that is best suited to an individual, managing adverse events, supporting medication adherence and monitoring programmatic performance

A new respiratory infectious disease, COVID-19, caused by a new coronavirus called SARS-CoV-2, emerged in early December 2019. Since then, the virus has spread to India and 106 other countries in Asia, Europe, North America, Africa, and Oceania. On March 11, the World Health Organization (WHO) decl...ared the outbreak a pandemic, which has since rapidly evolved. As an economic hub with substantial global connectivity and movement of people and goods, India is directly impacted by the COVID-19 pandemic. Although it is too early to gauge the full spectrum of the outbreak’s social and economic impacts, COVID-19 has already caused lockdowns in China, Korea, and in many countries in Europe, and in some states of India, suspension of schools and universities, disruption of food systems and other supply chains, as well as a slowdown in trade between India and rest of the world.

Key facts
- A healthy diet helps to protect against malnutrition in all its forms, as well as noncommunicable diseases (NCDs), including diabetes, heart disease, stroke and cancer.
- Unhealthy diet and lack of physical activity are leading global risks to health.
- Healthy dietary practices start... early in life – breastfeeding fosters healthy growth and improves cognitive development, and may have longer term health benefits such as reducing the risk of becoming overweight or obese and developing NCDs later in life.
- Energy intake (calories) should be in balance with energy expenditure. To avoid unhealthy weight gain, total fat should not exceed 30% of total energy intake (1, 2, 3). Intake of saturated fats should be less than 10% of total energy intake, and intake of trans-fats less than 1% of total energy intake, with a shift in fat consumption away from saturated fats and trans-fats to unsaturated fats (3), and towards the goal of eliminating industrially-produced trans-fats (4, 5, 6).
- Limiting intake of free sugars to less than 10% of total energy intake (2, 7) is part of a healthy diet. A further reduction to less than 5% of total energy intake is suggested for additional health benefits (7).
- Keeping salt intake to less than 5 g per day (equivalent to sodium intake of less than 2 g per day) helps to prevent hypertension, and reduces the risk of heart disease and stroke in the adult population (8).
- WHO Member States have agreed to reduce the global population’s intake of salt by 30% by 2025; they have also agreed to halt the rise in diabetes and obesity in adults and adolescents as well as in childhood overweight by 2025 (9, 10).

The One Health (OH) High-Level Expert Panel (OHHLEP) of the Quadripartite Organizations defined OH as an integrated, unifying approach that aims to sustainably balance and optimize the health of people, animals and ecosystems.”
It recognizes the health of humans, domestic and wild animals, plan...ts, and the wider environment (including ecosystems) are closely linked and interdependent [1]. The Tripartite which comprised the Food and Agriculture Organization (FAO) of the United Nations (UN), the World Health Organization (WHO), and the World Organisation for Animal Health (WOAH) later became the Quadripartite organizations when the United Nations Environment Programme (UNEP) joined the OH alliance in 2022. There are Global and Regional Quadripartite Secretariats consisting of officials of headquarters and regional offices, respectively.
Over the years, the Tripartite/Quadripartite organizations and other partner agencies have developed several OH assessment and operational tools to support Member States in assessing their core capacities to achieve compliance with the requirements of international standards such as the International Health Regulations 2005 (IHR), WOAH’s Terrestrial and Aquatic Animal Health Codes, World Trade Organization’s Sanitary and Phytosanitary Measures (WTO-SPS), FAO/WHO Codex standards, etc. Technical areas that the existing tools currently support include progress monitoring, coordination and collaboration mechanisms, and capacity building for prevention, detection, preparedness, and response to health threats emerging at human-animal-environment interface. More OH B operational tools are in the pipeline.

The Agenda has been developed under the umbrella of the WHO Global Strategy on Health, Environment, and Climate Change, and builds upon the commitments set forth in the Sustainable Health Agenda for the Americas 2018–2030 and the PAHO Strategic Plan 2020–2025. The Agenda was developed in consultation with the Technical Advisory Group and through a consensus-driven decision-making process with Member States during the 2019–2020 period. Looking toward the achievement of Sustainable Development Goal 3, the Agenda focuses on: improving the performance of environmental public health programs and institutions; fostering environmentally resilient and sustainable health systems; and promoting environmentally healthy and resilient cities and communities. Its implementation will be context-specific, based on the needs and realities of the countries. It will benefit countries and territories by promoting good governance practices, strengthening the leadership and coordination roles of the health sector, fostering cross-sectoral action, focusing on primary prevention, and enhancing evidence and communication. It will facilitate access to human, technical, and financial resources necessary to address environmental determinants of health and ensure that the Region is fully engaged in global health, environment, and climate change processes and agreements. The objective of the Agenda is to strengthen the capacity of health actors in the health and non-health sectors to address and adapt to environmental determinants of health (EDHs), prioritizing populations living in conditions of vulnerability, in order to meet Outcome 18 of the PAHO Strategic Plan 2020–2025 directly and several other outcomes of the Plan indirectly. To address and adapt to the challenges of EDHs in the Region, an integrated and evidence-informed approach within the health sector and across sectors will be needed, one enabled, and supported by good governance practices, adequate management mechanisms, high-level political will, and adequate human, technical, technological, and financial resources.

Background: Data on burden of peripheral artery disease (PAD) and its attributable risk factors are valuable for policymaking. We aimed to estimate the burden and risk factors for PAD from 1990 to 2019.
Methods: We extracted the data on prevalence, incidence, death, years lived with disability (YLD...s), and years of life lost (YLLs) from the Global Burden of Disease Study 2019 to measure PAD burden. Moreover, the attributable burden to PAD risk factors was also estimated.
Results: Globally, in 2019, 113,443,017 people lived with PAD and 10,504,092 new cases occurred, resulting in 74,063 deaths, 500,893 YLDs, and 1,035,487 YLLs. The absolute numbers of PAD prevalent and incident cases significantly increased between 1990 and 2019, contrasting with the decline trends in age-standardized prevalence and incidence rates. However, no statistically significant changes were detected in the global age-standardized death or YLL rates. The burden of PAD and its temporal trends varied significantly by location, gender, age group, and social-demographic status. Among all potentially modifiable risk factors, age-standardized PAD deaths worldwide were primarily attributable to high fasting plasma glucose, followed by high systolic blood pressure, tobacco, kidney dysfunction, diet high in sodium, and lead exposure.
Conclusion: PAD remained a serious public health problem worldwide. More strategies aimed at implementing cost-effective interventions and addressing modifiable risk factors should be carried out, especially in regions with high or increasing burden.

Cutaneous leishmaniasis (CL) is a parasitic disease caused by infection with a vector-borne protozoan parasite of the genus Leishmania spp. The parasite is transmitted by the bite of an infected phlebotomine sand fly. Infection results in skin lesions which take a long time to heal and may leave per...manent, disfiguring scars (de Vries et al. 2015). CL is classified as a neglected tropical disease (NTD), and in common with several other NTDs, is associated with psychosocial effects including stigma, social exclusion, and declining mental health (Bailey et al. 2019; Bennis et al. 2018; Wenning et al. 2022). Emerging evidence suggests that people with CL are at a higher risk of experiencing anxiety, depression, decreased body satisfaction, loss of social status, and lower quality of life (Bennis et al. 2018; Yanik et al. 2004). The global mean age-standardised disability-adjusted life years (DALYs) lost by CL was 0.58 per 100,000 people (Karimkhani et al. 2016). Notably, this statistic only considers the physical effects of the lesions and does not account for the potentially considerable psychological and social effects of CL (Bailey et al. 2017; Bailey et al. 2019; Wenning et al. 2022).
