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.

Rabies is a fatal viral zoonosis and serious public health problem.1 All mammals are believed to be susceptible to the disease, and for the purposes of this document, use of the term animal refers to mammals. The disease is an acute, progressive encephalitis caused by viruses in the genus Lyssavirus....
2 Rabies virus is the most important lyssavirus globally. In the
United States, multiple rabies virus variants are maintained in wild mammalian reservoir populations such as raccoons, skunks, foxes, and bats. Although the United States has been declared free from transmission of canine rabies virus variants, there is always a risk of reintroduction of these variants.The rabies virus is usually transmitted from animal to animal through bites. The incubation period is
highly variable. In domestic animals, it is generally 3 to 12 weeks, but can range from several days to months, exceeding 6 months.8 Rabies is communicable during the period of salivary shedding of rabies virus. Experimental and historic evidence documents that dogs, cats, and ferrets shed the virus for a few days prior to the onset of clinical signs and during illness. Clinical signs of rabies are variable and include inappetance, dysphagia, cranial nerve deficits, abnormal behavior, ataxia, paralysis, altered vocalization, and seizures. Progression to death is rapid. There are currently no known effective rabies antiviral drugs.

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).

Human schistosomiasis, a parasitic and often chronic illness, is one of the major neglected tropical diseases worldwide. It is estimated that 240 million people suffer from schistosomiasis, with more than 200000 fatalities recorded each year. Schistosomiasis is caused by an infection of the blood fl...uke Schistosoma and is transmitted to humans through direct contact with infected water.

Sleeping sickness is controlled by case detection and treatment but this often only reaches less than 75% of the population. Vector control is capable of completely interrupting HAT transmission but is not used because of expense. We conducted a full scale field trial of a refined vector control tec...hnology. From preliminary trials we determined the number of insecticidal tiny targets required to control tsetse populations by more than 90%. We then carried out a full scale, 500 km2 field trial covering two HAT foci in Northern Uganda (overall target density 5.7/km2). In 12 months tsetse populations declined by more than 90%. A mathematical model suggested that a 72% reduction in tsetse population is required to stop transmission in those settings. The Ugandan census suggests population density in the HAT foci is approximately 500 per km2. The estimated cost for a single round of active case detection (excluding treatment), covering 80% of the population, is US$433,333 (WHO figures). One year of vector control organised within country, which can completely stop HAT transmission, would cost US$42,700. The case for adding this new method of vector control to case detection and treatment is strong. We outline how such a component could be organised.

La santé mentale fait partie intégrante de notre santé et de notre bien-être en général et constitue un droit humain fondamental. À l'échelle mondiale, les problèmes de santé mentale sont très répandus. Selon les données de l'Organisation mondiale de la Santé (OMS), environ une personn...e sur huit dans le monde vit avec un trouble mental (OMS, 2022a). Les troubles mentaux sont la principale cause d'incapacité, entraînant 1 année sur 6 vécues avec une incapacité (OMS, 2022a).
Les personnes atteintes de troubles mentaux graves meurent en moyenne 10 à 20 ans plus tôt que la population générale, principalement en raison de maladies physiques évitables. Des circonstances défavorables, notamment la pauvreté, inégalités sociales et économiques, urgences de santé publique, guerres et crise climatique, font partie des menaces structurelles mondiales pour la santé mentale, entraînant un risque plus élevé de souffrance de problèmes de santé mentale.

Revised and expanded version of the Guidelines
These guidelines have been compiled for education ministries or other educational leaders (including development partners, non-governmental or private organizations working with schools or directly with caregivers) who want to adapt and adopt resources to support the marginalized caregivers of child...ren with disabilities.
The guidance presented in this document was developed by a team of international and national experts following a proof-of-concept pilot4 of the resources in two countries. The work was carried out between February 2021 and January 2022. The pilots demonstrated that principles and activities described in the resources could be carried out, in practical terms, in line with existing government programmes supporting the implementation of disability-inclusive education.

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.
