Snakebite envenoming is a serious public health problem in Central America, where approximately 5,500 cases occur every year. Panama has the highest incidence and El Salvador the lowest. The majority, and most severe, cases are inflicted by the pit viper Bothrops asper (family Viperidae), locally kn...own as ‘terciopelo’, ‘barba amarilla’ or ‘equis’. About 1% of the bites are caused by coral snakes of the genus Micrurus (family Elapidae). Despite significant and successful efforts in Central America regarding snakebite envenomings in the areas of research, antivenom manufacture and quality control, training of health professionals in the diagnosis and clinical management of bites, and prevention of snakebites, much remains to be done in order to further reduce the impact of this medical condition. This essay presents seven challenges for improving the confrontation of snakebite envenoming in Central America. Overcoming these challenges demands a coordinated partnership of highly diverse stakeholders though inter-sectorial and inter-programmatic interventions.

The WHO continuously reviews available data on SARS-CoV-2 variants of concern. For this version, the global epidemiological
situation of the COVID-19 pandemic as of 21 January 2022 – at a time when the Omicron VOC had been identified in 171
countries across all six WHO Regions and was rapidly re...placing Delta worldwide – was considered Omicron has a substantial growth advantage, higher secondary attack rates and a higher observed reproduction number than Delta.
There is now significant evidence that immune evasion contributes to the rapid spread of Omicron. Other factors may be a shorter
serial interval (by about 0.8 to 1.2 days compared to Delta) and potential increased intrinsic transmission fitness . There is
growing evidence that with Omicron, there is lower vaccine effectiveness (VE) against infection and symptomatic disease soon after vaccination compared to Delta. There is also evidence of accelerated waning of VE over time of the primary series against infection and symptomatic disease for the studied vaccines. Further studies are required to better understand the drivers of transmission and declining incidence in various settings. These factors include the intrinsic transmission fitness properties of the virus, degree of immune evasion, vaccination coverage and level of vaccine-derived and post-infection immunity, levels of social mixing and degree of application of public health and social measures (PHSM).

Rabies is a disease of animals but too often the outcome is gauged in terms of human suffering and
death. Despite this, in areas of the world where rabies is endemic there is often a lack of communication between veterinary and medical professionals, to the extent that the disease continues to thri...ve and potential victims are not treated. The problem is partly
exacerbated by a lack of awareness and experience of the disease and of what to do when confronted by suspect cases. In these technologically advanced days, although it is possible to learn “all there is to know” about almost any subject, it is sometimes difficult to distil the essence.

Avec l’essor des traitements antirétroviraux (TAR) à base de dolutégravir (DTG) pour soigner les personnes vivant avec

populations sous TAR. Bien que la résistance au DT...G ne soit pas apparue dans les populations naïves aux TAR incapables
de supprimer la charge virale dans les essais cliniques, certains éléments portent à croire que la résistance au
DTG peut émerger chez les personnes suivant des schémas thérapeutiques incluant le DTG. L’OMS recommande aux
pays qui étendent les TAR incluant le DTG d’accompagner ce déploiement d’une surveillance en routine de la pharmacorésistance

Today, patient harm due to unsafe care is a large and growing global public health challenge and is one of the
leading causes of death and disability worldwide. Most of this patient harm is avoidable. As countries strive to
achieve universal health coverage and the Sustainable Development Goals, t...he beneficial effects of improved
access to health services can be undermined by unsafe care. Patient safety incidents can cause death and
disability, and suffering for victims and their families. The financial and economic costs of safety lapses are high.
There is often reduced public confidence and trust in local health systems when such incidents are publicized.
Health workers involved in serious incidents involving death or serious harm to a patient can also suffer lasting
psychological harm and deep-seated feelings of guilt and self-criticism.

Promoting health and preventing disease is a critical component of the effort required to achieve Universal Health Coverage (UHC). to date, efforts to achieve UHC have focused mostly on strengthening health systems and their capacities to provide curative care. However, experience from the COVID-19 ...pandemic has reaffirmed the need for resilient health systems, emphasizing primary health care, including preventive and promotive health and well-being.
Emerging from the eye of the storm as the global health lead agency during the pandemic, WHO is equipped with the required insights and actions for a holistic approach to “building back fairer and better” after COVID-19.
The Healthier Populations (UHP) Cluster in the African Region is designed to support Pillar 3 of WHO’s 13th Global Programme of Work (GPW13) which aims to make 1 billion people healthier by reducing health inequities, preventing diseases and injuries, addressing health determinants, and promoting partnerships for collaborative actions amongst all stakeholders.

The full-scale invasion of Ukraine has caused a deterioration in the level of access to health-care services and medicines in the country, particularly for people living in regions close to the front line and areas that are not partially or fully controlled by the Government of Ukraine, and for peop...le who have been internally displaced. Cost and time constraints involved in getting to and from health facilities, as well as limited transportation options were the main barriers to accessing essential health-care services. At the same time, the findings show that the country’s health system remains resilient and that overall access to health services is fairly high.This report is based on data collected through a quantitative cross-sectional survey of self-reported health needs of the general population in Ukraine. It presents results of the first round survey conducted in September 2022 and could help to address the specific health-care needs of the population groups concerned.

The annual Joint Meeting of the Food and Agriculture Organization of the United Nations (FAO) Panel of Experts on Pesticide Residues in Food and the Environment and the World Health Organization (WHO) Core Assessment Group on Pesticide Residues (JMPR) was held in Rome, Italy, from 13 to 22 September.... The FAO panel of experts had met in preparatory sessions from 8 to 12 September. The Meeting was held in pursuance of recommendations made by previous Meetings and accepted by the governing bodies of FAO and WHO that studies should be undertaken jointly by experts to evaluate possible hazards to humans arising from the occurrence of pesticide residues in foods. During the meeting the FAO Panel of Experts was responsible for reviewing pesticide use patterns (use of good agricultural practices), data on the chemistry and composition of the pesticides and methods of analysis for pesticide residues and for estimating the maximum residue levels that might occur as a result of the use of the pesticides according to good agricultural use practices. The WHO Core Assessment Group was responsible for reviewing toxicological and related data and for estimating, where possible and appropriate, acceptable daily intakes (ADIs) and acute reference doses (ARfDs) of the pesticides for humans. This report contains information on ADIs, ARfDs, maximum residue levels, and general principles for the evaluation of pesticides. The recommendations of the Joint Meeting, including further research and information, are proposed for use by Member governments of the respective agencies and other interested parties.

Forests, trees and green spaces, hereinafter ‘forests and trees’ for short, provide multiple goods and services that contribute to human health. These include medicines, nutritious foods and other non-wood forest products (NWFPs). Globally, at least 3.5 billion people use NWFPs, including medici...nal plants, which are particularly important for vulnerable groups and Indigenous Peoples and local communities (IPLCs).
During periods of crises, such as the COVID-19 pandemic, demand for forest products typically increases amongst these groups. Forests and trees also contribute to better health by playing a role in climate change
mitigation and adaptation, contributing to regulating the carbon cycle, but also moderating the micro-climate, filtering pollutants from the air and protecting settlements against the effects of extreme events such as droughts and flash floods.

Chagas disease is currently endemic and also predicted to be at increased transmission risk under future climate change scenarios. Similarly, an expansion of areas in the United States at increased risk for Chagas disease transmission is also expected over the next several decades under climate chan...ge scenarios. Of particular interest is the predicted northern shift of triatomine species to central regions of the United States with historically unsuitable climates for T. cruzi vectors. The weight of evidence regarding the influences climate change may pose on T. cruzi vector species distributions demonstrates the sensitivity of Chagas disease transmission to future climate variability. In order to advance forecasts for the impact climate change may have on Chagas disease transmission in the Americas, it is imperative to
further develop, utilize, and perhaps combine predictive species distribution modeling approaches that integrate accurate, long term data on climate variables, vector species distributions, Chagas disease incidence, as well as other socio-ecological variables.
