In the Region of the Americas, the leishmaniases are a group of diseases caused by various species of Leishmania, which cause a set of clinical syndromes in infected humans that can involve the skin, mucosa, and visceral organs. The spectrum of clinical disease is varied and depends on the interacti...on of several factors related to the parasite, the vector, and the host. Cutaneous leishmaniasis is the form most frequently reported in the Region and nearly 90% of cases present single or multiple localized lesions. Other cutaneous clinical forms, such as disseminated and diffuse cutaneous leishmaniasis, are more difficult to treat and relapses are common. The mucosal form is serious because it can cause disfigurement and severe disability if not diagnosed and treated early on. Visceral leishmaniasis is the most severe form, as it can cause death in up to 90% of untreated people.

The number of COVID-19 cases is on the rise again, with South Africa nearing half of all confirmed cases in the WHO African Region. Threats of new variants loom and low vaccination coverage raises questions on the future of the response to COVID-19. Prevention remains the key strategy in most sub-Sa...haran countries. Five National Centres (NCs) from the African Health Observatory Platform on Health Systems and Policies (AHOP), based in Ethiopia, Kenya, Nigeria, Rwanda and Senegal, reflect on lessons to be learnt from their containment responses in the initial phases. They construct timelines to highlight the policies and challenges associated with introducing a range of public health containment measures and
discuss the extent to which these measures continue to be valuable given the ever-changing nature of the pandemic.

The overview of findings from five Latin American countries
INTRODUCTION: The COVID-19 pandemic has disrupted health systems around the world. The objectives of this study are to estimate the overall effect of the pandemic on essential health service use and outcomes in Mexico, describe observed and predicted trends in services over 24 months, and to estimat...e the number of visits lost through December 2020.
METHODS: We used health information system data for January 2019 to December 2020 from the Mexican Institute of Social Security (IMSS), which provides health services for more than half of Mexico's population-65 million people. Our analysis includes nine indicators of service use and three outcome indicators for reproductive, maternal and child health and non-communicable disease services. We used an interrupted time series design and linear generalised estimating equation models to estimate the change in service use and outcomes from April to December 2020. Estimates were expressed using average marginal effects on the risk ratio scale.
RESULTS: The study found that across nine health services, an estimated 8.74 million patient visits were lost in Mexico. This included a decline of over two thirds for breast and cervical cancer screenings (79% and 68%, respectively), over half for sick child visits and female contraceptive services, approximately one-third for childhood vaccinations, diabetes, hypertension and antenatal care consultations, and a decline of 10% for deliveries performed at IMSS. In terms of patient outcomes, the proportion of patients with diabetes and hypertension with controlled conditions declined by 22% and 17%, respectively. Caesarean section rate did not change.
CONCLUSION: Significant disruptions in health services show that the pandemic has strained the resilience of the Mexican health system and calls for urgent efforts to resume essential services and plan for catching up on missed preventive care even as the COVID-19 crisis continues in Mexico.

Checklist for risk and impact management of pandemics of COVID-19
During fresh fruit and vegetables (FFV) production, water is used for a variety of purposes. Even the water was conventionally treated and disinfected, it may still potentially contain human pathogens, albeit at low concentrations. A risk assessment, appropriate to the national or local production c...ontext, should be conducted to assess the potential risks associated with a specific water source or supply in order to devise the appropriate risk mitigation strategies.
Since the 48th session of Codex Committee on Food Hygiene (CCFH) noted the importance of water safety and quality in food production and processing, FAO and WHO has undertaken the work on this subject. This report describes the output of the third in a series of meetings, which examined appropriate and fit-for-purpose microbiological criteria for water used with fresh fruit and vegetables. The advice herein will support decision making when applying the concept of fit-for-purpose water for use in the pre- and post-harvest production of fresh fruit and vegetables.

Mosquito-borne diseases are expanding their range, and re-emerging in areas where they had subsided for decades. The extent to which climate change influences the transmission suitability and population at risk of mosquito-borne diseases across different altitudes and population densities has not be...en investigated. The aim of this study was to quantify the extent to which climate change will influence the length of the transmission season and estimate the population at risk of mosquito-borne diseases in the future, given different population densities across an altitudinal gradient.

WHY THIS GUIDE?
Because, in the face of crises and emergencies, it is vital to include a human rights perspective in responses. Vulnerable groups face major obstacles to accessing and benefiting from prevention, mitigation, and health care policies due to structural barriers of inequality. To offer... guidelines to the countries of the Americas for crafting and implementing inclusive and accessible, human rights-based responses to a pandemic that is unprecedented in the region and in the world as a whole.

Evidence-based guidelines are one of the most useful tools for improving public health and clinical practice. Their purpose is to formulate interventions based on strong evidence of efficacy, avoid unnecessary risks, use resources efficiently, reduce clinical variability and, in essence, improve hea...lth and ensure quality care, which is the purpose of health systems and services. These guidelines were developed following the GRADE methodology, with the support of a panel of clinical experts from different countries, all convened by the Pan American Health Organization. By responding to twelve key questions about the clinical diagnosis and treatment of dengue, chikungunya, and Zika, evidence-based recommendations were formulated for pediatric, youth, adult, older adult, and pregnant patients who are exposed to these diseases or have a suspected or confirmed diagnosis of infection. The purpose of the guidelines is to prevent progression to severe forms of these diseases and the fatal events they may cause. The recommendations are intended for health professionals, including general, resident, and specialist physicians, nursing professionals, and medical and nursing students, who participate in caring for patients with suspected dengue, chikungunya, or Zika. They are also intended for health unit managers and the executive teams of national arboviral disease prevention and control programs, who are responsible for facilitating the process of implementing these guidelines.

The results of the report clearly show that in 2020, a year dominated by the emergence of COVID-19 and its associated health and economic crises, governments around the world rose to the challenge. Sharp increases in government spending on health at all country income levels underpinned the rise in ...health spending to a new high of US $9 trillion (approximately 11% of global GDP). Government health spending generally increased and offset declines in out-of-pocket spending. Importantly, the rise in government health spending was part of a much broader fiscal response to the pandemic. In high income and upper-middle income countries social protection spending also increased sharply in as governments attempted to cushion populations from the economic impacts of COVID-19. In contrast to health and social protection, growth in education spending was relatively subdued. Countries face the further challenge of sustaining increased public spending on health and other social sectors in the face of deteriorating macroeconomic conditions and rising debt servicing. This also includes the challenge of sustaining external support for low income countries, which is essential for reducing ensuring poverty, ensuring access to health services and strengthening pandemic preparedness.

WHO needs US$2.54 billion to provide life-saving assistance to millions of people around the world facing health emergencies. WHO’s Health Emergency Appeal is a consolidation of WHO’s priorities and financial requirements for 2023 to carry out health interventions in emergency and humanitarian r...esponses. The number of people in need of humanitarian relief has increased by almost a quarter compared to 2022, to a record 339 million. WHO is responding to an unprecedented number of intersecting health emergencies: climate change-related disasters such as flooding in Pakistan and food insecurity across the Sahel in the greater Horn of Africa; the war in Ukraine; and the health impact of conflict in Yemen, Afghanistan, Syria and north eastern Ethiopia – all of these emergencies overlapping with the health system disruptions caused by the COVID-19 pandemic and outbreaks of measles, cholera, and other killers. Contributions to the appeal can be fully flexible, flexible across a region, or flexible within a country appeal.

This document presents the World Health Organization Operational framework for building climate resilient and low carbon health systems*. ***The framework's goal is to increase the climate resilience of health systems to protect and improve the health of communities in an unstable and changing clima...te, while optimizing the use of resources and implementing strategies to reduce GHG emissions. It aims to contribute to the design of transformative health systems that can provide safe and quality care in a changing climate.
Implementation of the framework's ten components would help health organizations, authorities, and programmes to be better able to anticipate, prevent, prepare for, and manage climate-related health risks and therefore decrease the burden of associated climate-sensitive health outcomes. Implementing low carbon health practices would contribute to climate change mitigation while also improving health outcomes. Achieving these aims is an important contribution to universal health coverage (UHC), global health security, and specific targets within the Sustainable Development Goals (SDGs). The document is a useful resource for decision-makers in health systems, including public health agencies, and other specialized institutions, and for decision-makers in health-determining sectors.
