Diphtheria is caused by Corynebacterium species, mostly by toxin-producing Corynebacterium diphtheriae and rarely by toxin-producing strains of C. ulcerans and C. pseudotuberculosis. The most common type of diphtheria is classic respiratory diphtheria, whereby the exotoxin produced characteristicall...y causes the formation of a pseudomembrane in the upper respiratory tract and damages other organs, usually the myocardium and peripheral nerves. Acute respiratory obstruction, acute systemic toxicity, myocarditis and neurologic complications are the usual causes of death. The infection can also affect the skin (cutaneous diphtheria). More rarely, it can affect mucous membranes at other non-respiratory sites, such as genitalia and conjunctiva.
C. diphtheriae is transmitted from person to person by intimate respiratory and direct contact; in contrast, C. ulcerans and C. pseudotuberculosis are zoonotic infections, not transmitted person-to-person. The incubation period of C. diphtheriae is two to five days (range 1– 10 days). A person is infectious as long as virulent bacteria are present in respiratory secretions, usually two weeks without antibiotics, and seldom more than six weeks. In rare cases, chronic carriers may shed organisms for six months or more. Skin lesions are often chronic and infectious for longer periods. Effective antibiotic therapy (penicillin or erythromycin) promptly terminates shedding in about one or two days.

Todos los países de la Región de las Américas en los que la malaria es endémica han asumido el reto de eliminar la enfermedad y de poner en marcha medidas para orientar sus programas y estrategias de salud en esa dirección. En este manual se explica cómo ejecutar las medidas con vistas a logra...r la eliminación de la malaria y prevenir su restablecimiento, mediante el aumento de la intensidad y la calidad de las medidas, la reorientación de las iniciativas, la reducción de los retrasos que favorecen la transmisión y un monitoreo adecuado que permita ajustar las intervenciones. En este sentido, se propone como primer paso estratificar el territorio —de modo que se puedan planificar y priorizar las intervenciones y grupos de población— para, a continuación, aplicar una medida de diagnóstico, tratamiento, investigación y respuesta como estrategia clave dirigida a hacer efectiva la eliminación de la enfermedad y a prevenir su restablecimiento en todos los estratos. Además, el documento trata de hacer operativo el concepto de vigilancia, como intervención promovida por la Organización Mundial de la Salud a través de la Estrategia Técnica Mundial contra la Malaria 2016-2030, y destaca la importancia de que las comunidades tengan acceso al diagnóstico y el tratamiento tempranos. Por último, en el manual también se incluyen aspectos de gestión y monitoreo que deben tenerse en cuenta para la eliminación de los focos de transmisión.

El objetivo de esta nota conceptual y del marco que describe es la eliminación de un grupo de enfermedades transmisibles y los efectos negativos sobre la salud que generan que juntos crean una carga tangible en las personas afectadas, sus familias y comunidades, y en los sistemas de atención de sa...lud en toda la Región. Aunque no hay consenso sobre las mejores medidas que se deben usar para la salud de las personas y de acuerdo con la situación epidemiológica de un país, es habitual medir la carga de enfermedad mediante las tasas de enfermedad (incidencia, prevalencia, etc.), las tasas de mortalidad por enfermedad específica, las tasas de morbilidad y mortalidad comparativas, la distribución geográfica y los años de vida ajustados en función de la discapacidad (AVAD)…. Se analiza la situación epidemiológica actual, incluidos los datos sobre tasas de enfermedad o distribución geográfica para las enfermedades del cuadro 1. Hotez et al. (2008) fueron los primeros en examinar y comparar la carga de los AVAD en América Latina y el Caribe para las ETD, la infección por el VIH/sida, la malaria y la tuberculosis como era hace unos diez años atrás. Aunque la carga regional de tuberculosis, malaria y enfermedades infecciosas desatendidas (EID) es algo menor a la de hace diez años, se sigue perdiendo la posibilidad de trabajar (y de asistir a la escuela) debido a la enfermedad y muerte prematura o discapacidad, y la necesidad de acelerar los esfuerzos para eliminar las enfermedades es evidente en todas las comunidades en situación de vulnerabilidad.

L͛analyse des tendances récentes montre que le Burkina Faso a enregistré une réduction significative de la mortalité infanto-juvénile. Même si aucune des cibles des OMD 4 et 5 n͛a été atteinte par le pays, le taux de mortalité infanto-juvénile est passé de 129 ...pour mille naissances vivantes en 2010 à 82 pour mille naissances
vivantes en 2015, soit une baisse de 7.3% par an. Ceci est en grande partie dû aux progrès enregistrés en matière de lutte contre la mortalité au bénéfice de la tranche juvénile (de 1 à 4 ans). Cependant, comme près de la moitié des enfants âgés de moins de cinq ans continuent de mourir au cours de leur première
année de vie, il reste beaucoup à faire pour l͛atteinte de la vision globale d͛élimination de la mortalité infanto-juvénile évitable et de réduction de la mortalité des mères comme partie prenante des Objectifs de Développement Durable (ODD).

Hendra virus (HeV) continues to pose a serious public health concern as spillover events occur sporadically. Terminally ill horses can exhibit a range of clinical signs including frothy nasal discharge, ataxia or forebrain signs. Early signs, if detected, can include depression, inappetence, colic o...r mild respiratory signs. All unvaccinated ill horses in areas where flying foxes exist, may potentially be infected with HeV, posing a significant risk to the veterinary community. Equivac® HeV vaccine has been fully registered in Australia since 2015 (and under an Australian Pesticides and Veterinary Medicines Authority special permit since 2012) for immunization of horses against HeV and is the most effective and direct solution to prevent disease transmission to horses and protect humans. No HeV vaccinated horse has tested positive for HeV infection. There is no registered vaccine to prevent, or therapeutics to treat, HeV infection in humans. Previous equine HeV outbreaks tended to cluster in winter overlapping with the foaling season (August to December), when veterinarians and horse owners have frequent close contact with horses and their bodily fluids, increasing the chance of zoonotic disease transmission. The most southerly case was detected in 2019 in the Upper Hunter region in New South Wales, which is Australia's Thoroughbred horse breeding capital. Future spillover events are predicted to move further south and inland in Queensland and New South Wales, aligning with the moving distribution of the main reservoir hosts. Here we (1) review HeV epidemiology and climate change predicted infection dynamics, (2) present a biosecurity protocol for veterinary clinics and hospitals to adopt, and (3) describe diagnostic tests currently available and those under development. Major knowledge and research gaps have been identified, including evaluation of vaccine efficacy in foals to assess current vaccination protocol recommendations.

Psychological first aid (PFA) is a method of helping people in distress so they feel calm and supported to cope better with their challenges. It is a way of assisting someone to manage their situation and make informed decisions. The basis of psychological first aid is caring about the person in dis...tress and showing empathy. It involves paying attention to reactions, active listening and, if needed, practical assistance, such as problem solving, help to access basic needs or referring to further options for assistance. PFA helps normalize worry and other emotions, PFA also promotes healthy coping and provides feelings of safety, calming, and hope. These guidelines can be used by Red Cross Red Crescent National Societies to set up and run different kind of remote services for the public during the time of a COVID-19 response. It should be noted that the target group for the guidelines are adults.

2023 is seeing intense heatwaves. According to a July 2023 briefing by the World Meteorological Association temperatures will frequently reach above 35–40°C in many places across the Mediterranean region, with temperatures in the Middle East and southeastern Türkiye reaching up to 45°C and, in ...North Africa, 44–49°C. April–May 2023 also saw temperature records broken across many parts of Asia, including Thailand, Laos and Myanmar.
The IPCC predicts that 420 million people will be exposed to extreme heat and heatwaves in the near future. Hundreds of thousands of people die from preventable heat-related causes each year, while temperature extremes and wildfires cause devastation to lives and livelihoods. According to the WMO, ‘heatwaves are amongst the deadliest natural hazards [and] heat is a rapidly growing health risk’.

Guiding the work of medica mondiale is an attitude of sensitivity towards both trauma and stress.
This stress- and trauma-sensitive approach has a strengthening and relieving effect on the affected
people and also the activists, specialist staff and working groups. For medica mondiale, trauma as a...
consequence of violence is not to be found exclusively in the area of (individual) psychology, but also
very significantly at the level of society and politics. For this reason, even a multi-sectoral approach
to supporting those affected by violence cannot stand alone: it must go hand in hand with measures
to bring about change in general political conditions, societal structures and public awareness.

La thèse de Yobouet Inès Kouakou, soutenue à l’Université Claude Bernard Lyon 1, porte sur le traitement d’urgence du paludisme sévère chez l’enfant à l’aide d’une administration intranasale d’artésunate. L’objectif principal de ce travail est d’explorer, in vitro, la voie na...sale comme alternative à la voie intra-rectale recommandée actuellement en pré-hospitalier. L’étude démontre la non-toxicité de formulations d’artésunate sur un modèle de muqueuse nasale humaine, bien que la perméation observée reste faible. Des pistes sont proposées pour améliorer cette perméation, notamment par l’optimisation galénique. La thèse inclut également une revue de la pharmacocinétique de l’artésunate et le développement de méthodes de dosage simples et peu coûteuses, adaptées aux laboratoires à ressources limitées. Ce travail s’inscrit dans une démarche de lutte contre le paludisme, notamment en zones rurales où l’accès aux soins reste difficile.
