Parasites & Vectors volume 11, Article number: 264 (2018)
Dengue creates a staggering epidemiological and economic burden for endemic countries. Without a specific therapy and with a commercial vaccine that presents some problems relative to its full effectiveness, initiatives to improve vector... control strategies, early disease diagnostics and the development of vaccines and antiviral drugs are priorities. In this study, we present the probable origins of dengue in America and the trajectories of its spread. Overall, dengue diagnostics are costly, making the monitoring of dengue epidemiology more difficult and affecting physicians’ therapeutic decisions regarding dengue patients, especially in developing countries. This review also highlights some recent and important findings regarding dengue in Brazil and the Americas. We also summarize the existing DENV polymerase chain reaction (PCR) diagnostic tests to provide an improved reference since these tests are useful and accurate at discriminating DENV from other flaviviruses that co-circulate in the Americas. Additionally, these DENV PCR assays ensure virus serotyping, enabling epidemiologic monitoring.

Buruli ulcer is caused by infection with Mycobacterium ulcerans. The disease is reported in more than 33 countries worldwide, but only about half of these countries regularly report data to WHO; most cases are reported from subregions of West and Central Africa. The mode of transmission is not known....
About half of those affected are children aged under 15 years; there is no gender difference. Diagnosis is based mainly on clinical and epidemiological characteristics. Of the four methods used for laboratory confirmation (microscopy, polymerase chain reaction (PCR), histopathology and culture), PCR is the most rapid and widely used. Other rapid methods for detection of mycolactone in lesions from suspected cases, such as fluorescent thin-layer chromatography, are under evaluation in four countries in Africa.
Research to develop point-of-care tests is in progress. Treatment of Buruli ulcer comprises 8 weeks of combined antibiotics (rifampicin and clarithromycin). Complementary therapies such as wound care, skin graft and prevention of disability are needed in some cases to ensure full recovery.
The target set by the World Health Organization (WHO) for control of Buruli ulcer is for countries to achieve a rate of case confirmation by PCR of at least 70%. All endemic countries have at least one PCR facility to support confirmation of cases. However, most countries in the WHO African Region have not been able to reach the target, and the rate of case confirmation has been declining

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.

PTSD Rating Scales: Two rating scales can be used by clinicians to help identify children's or adolescents' exposure to child abuse, interpersonal violence and other traumatic events, to identify PTSD symptoms, and to monitor symptoms. These are the UCLA PTSD Reaction Index (RI) and the Child PTSD S...ymptom Scale (CPSS). The RI is rated separately by the child or adolescent and a parent; the CPSS is rated only by the child or adolescent. This is the Child PTSD Symptom Scale. | Accessed online February 2019

ALMHAR is designed for refugees who had to flee from their homes and who are may be living in exile.
Fleeing your home is an incredibly overwhelming, frightening and life-changing experience. Many refugees who had to leave their homes and countries develop some sort of emotional or physical problems due to their experiences. If this is the case for you, it does not mean you are weak or crazy. Such problems are mostly normal reactions of normal people to abnormal experiences!
The app explains the most common emotional problems you might experience as a refugee and offers first support in dealing with them. It offers background information on 12 common problem areas and gives practical and easy to-do tips.

Background: Evidence based treatment interventions for young people with first-episode psychosis (FEP) and trauma histories is lacking. Although case formulation (CF) has been widely regarded in cognitive behavioural therapy manuals as beneficial, there is limited empirical research examining how cl...ients and therapists experience the process. Aim: This study aimed to explore young people’s reactions to CF in treatment for PTSD (post-traumatic stress disorder) and FEP

Children and youth can face emotional strains after a traumatic event such as a car crash or violence. Disasters also may leave them with long-lasting harmful effects. When children experience a trauma, watch it on TV, or overhear others discussing it, they can feel scared, confused, or anxious. You...ng people react to trauma differently than adults. Some may react right away; others may show signs that they are having a difficult time much later. As such, adults do not always know when a child needs help coping. This tip sheet will help parents, caregivers, and teachers learn some common reactions, respond in a helpful way, and know when to seek support.

AACAP OFFICIAL ACTION | This Practice Parameter identifies best approaches to the assessment and management of children and adolescents across all phases of a disaster. Delivered within a disaster system of care, many interventions are appropriate for implementation in the weeks and months after a d...isaster. These include psychological first aid, family outreach, psychoeducation, social support, screening, and anxiety reduction techniques. The clinician should assess and monitor risk and protective factors across all phases of a disaster. Schools are a natural site for conducting assessments and delivering services to children. Multimodal approaches using social support, psychoeducation, and cognitive behavioral techniques have the strongest evidence base. Psychopharmacologic interventions are not generally used but may be necessary as an adjunct to other interventions for children with severe reactions or coexisting psychiatric conditions

Post-Traumatic Stress Disorder (PTSD) in children and adolescents occurs when a child is exposed to one or more events that are unexpected, uncontrollable, life-threatening, and likely to cause serious harm or injury to himself/herself or someone significantly important to the child. In response, th...e child experiences fear, hopelessness, or horror and responds with a characteristic set of physiological and psychological reactions, which perpetuates the overwhelming and confusing feelings. Symptoms are characterized into three groups: persistent, intrusive re-experiencing of traumatic recollections; avoidance of reminders/numbing; and increased arousal.

SLe concept des médicaments essentiels a été utilisé pour la première fois par l'Organisation Mondiale de la Santé (OMS) dans les années 70 pour permettre aux Etats membres de faire face à la prolifération des médicaments sur le marché en tirant un meilleur rapport coût/efficacité des r...esources allouées à la santé grâce à une sélection et à une gestion rationnelle des médicaments.
Les médicaments essentiels permettent de soigner à moindre coût et de manière efficace la majorité des pathologies d'une région donnée. Ce concept s'est étendu depuis peu aux réactifs pour analyse médicales et aux dispositifs médicaux.
La première édition de la Liste Nationale des Médicaments Essentiels dans le pays a été élaboré en 1992 en s'inspirant de la première liste modèle de l'OMS.

Mpox is an emerging zoonotic disease caused by the mpox virus, a member of the Orthopoxvirus genus closely related to the variola virus that causes smallpox. Mpox was first discovered in 1958 when outbreaks of a pox-like disease occurred in monkeys kept for research. The first human case was recorde...d in 1970 in the Democratic Republic of the Congo (DRC) during a period of intensified effort to eliminate smallpox and since then the infection has been reported in a number of African countries. Mpox can spread in humans through close contact, usually skin-to-skin contact, including sexual contact, with an infected person or animal, as well as with materials contaminated with the virus such as clothing, beddings and towels, and respiratory droplets in prolonged face to face contact. People remain infectious from the onset of symptoms until all the lesions have scabbed and healed. The virus may spread from infected animals through handling infected meat or through bites or scratches. Diagnosis is confirmed by polymerase chain reaction (PCR) testing of material from a lesion for the virus’s DNA. Two separate clades of the mpox virus are currently circulating in Africa: Clade I, which includes subclades Ia and Ib, and Clade II, comprising subclades IIa and IIb. Clade Ia and Clade Ib have been associated with ongoing human-to-human transmission and are presently responsible for outbreaks in the Democratic Republic of the Congo (DRC), while Clade Ib is also contributing to outbreaks in Burundi and other countries.
In 2022‒2023 mpox caused a global outbreak in over 110 countries, most of which had no previous history of the disease, primarily driven by human-to-human transmission of clade II through sexual contact. In just over a year, over 90,000 cases and 150 deaths were reported to the WHO. For the second time since 2022, mpox has been declared a global health emergency as the virus spreads rapidly across the African continent. On 13 Aug 2024, Africa CDC declared the ongoing mpox outbreak a Public Health Emergency of Continental Security (PHECS), marking the first such declaration by the agency since its inception in 2017.7 This declaration empowered the Africa CDC to lead and coordinate responses to the mpox outbreak across affected African countries. On August 14, 2024, the WHO declared the resurgence of mpox a Public Health Emergency of International Concern (PHEIC) emphasizing the need for coordinated international response.
As of August 2024, Mpox has expanded beyond its traditional endemic regions, with new cases reported in countries including Sweden, Thailand, the Philippines, and Pakistan. Sweden has confirmed its first case of Clade 1 variant, which has been rapidly spreading in Africa, particularly in DRC. The emergence of this new variant raises concerns about its potential for higher lethality and transmission rates outside Africa.

This review focusses on the interactions between the etiologic agent of Chagas disease, Trypanosoma cruzi, and its triatomine vector. The flagellate mainly colonizes the intestinal tract of the insect. The effect of triatomines on trypanosomes is indicated by susceptibility and refractoriness phenom...ena that vary according to the combination of the strains. Other effects are apparent in the different regions of the gut. In the stomach, the majority of ingested blood trypomastigotes are killed while the remaining transform to round stages. In the small intestine, these develop into epimastigotes, the main replicative stage. In the rectum, the population density is the highest and is where the infectious stage develops, the metacyclic trypomastigote. In all regions of the gut, starvation and feeding of the triatomine affect T. cruzi. In the small intestine and rectum, starvation reduces the population density and more spheromastigotes develop. In the rectum, feeding after short-term starvation induces metacyclogenesis and after long-term starvation the development of specific cells, containing several nuclei, kinetoplasts and flagella. When considering the effects of T. cruzi on triatomines, the flagellate seems to be of low pathogenicity. However, during stressful periods, which are normal in natural populations, effects occur often on the behaviour, eg, in readiness to approach the host, the period of time before defecation, dispersal and aggregation. In nymphs, the duration of the different instars and the mortality rates increase, but this seems to be induced by repeated infections or blood quality by the feeding on infected hosts. Starvation resistance is often reduced by infection. Longevity and reproduction of adults is reduced, but only after infection with some strains of T. cruzi. Only components of the surface coat of blood trypomastigotes induce an immune reaction. However, this seems to act against gut bacteria and favours the development of T. cruzi.

RÉSUMÉ D’ORIENTATION
L’objectif des présentes orientations est de renforcer la capacité des établissements de santé à protéger et à améliorer la santé des communautés desservies face à un climat instable et changeant ; et de donner aux établissements de santé les moyens d’assur...er leur durabilité environnementale, grâce à une meilleure utilisation des ressources et à une diminution du rejet de déchets dans l’environnement. En étant résilients au changement climatique et écologiquement viables, les établissements de santé peuvent offrir des soins de qualité et des services plus accessibles, et en contribuant à réduire les coûts des établissements, ils garantissent également la prestation de soins plus abordables. Ils représentent par conséquent un élément important de la couverture sanitaire universelle (CSU).
Le présent document a pour objectif de :
guider les professionnels travaillant dans des structures de soins de santé de manière à ce qu’ils comprennent les risques sanitaires supplémentaires liés au changement climatique et qu’ils s’y préparent efficacement ;
renforcer la capacité à exercer une surveillance efficace des maladies liées au climat ; et à suivre, anticiper, gérer les risques sanitaires associés au changement climatique et à s’y adapter ;
inciter les responsables des établissements de santé à collaborer avec les secteurs déterminants pour la santé (notamment l’eau et l’assainissement, l’énergie, les transports, l’alimentation, l’urbanisme, l’environnement) afin de se préparer aux risques sanitaires supplémentaires posés par le changement climatique grâce à l’adoption d’une approche de résilience, et à promouvoir des pratiques écologiquement durables dans la prestation des services ;
fournir des outils pour aider les responsables des établissements de santé à évaluer leur résilience face aux menaces liées au changement climatique et leur durabilité environnementale, sur la base de l’utilisation appropriée des ressources (en particulier l’eau et l’énergie et les achats durables), et du rejet de matières dangereuses (biologiques, chimiques, radiologiques) dans leur environnement ;
promouvoir des mesures visant à garantir que les établissements de santé soient constamment et de plus en plus solides et continuent d’être efficaces et réactifs pour améliorer la santé et contribuer à réduire les inégalités et la vulnérabilité dans leur contexte local.

Under the theme “Stronger Together”, the campaign aims to offer information and strategies to assist communities in the region in better coping with the psychological impact of adverse events before, during and after a disaster situation. It also aims to raise awareness to reduce the stigma abou...t seeking mental health and psychosocial support.
You can download a wide range of communication material: videos, posters, radio jingles, guidebooks.
The Caribbean is highly prone to natural hazards, including seismic activity, hurricanes, landslides and floods. These events have resulted in lost lives, serious injuries and severe damage to housing and infrastructure. A single hurricane event can affect more than one island, and completely erase the gains of many years of productivity. As a result, these unpredictable hazards create disruption and have an ongoing impact on people’s lives - affecting their mental health and psychosocial well-being.
Although everyone is affected in some way by disaster events, there are a wide range of reactions and feelings that a person can experience. People may feel overwhelmed, confused or very uncertain about what is happening. They can also feel very fearful, anxious, numb or detached. People who feel safe, connected, calm and hopeful, have access to social, physical and emotional support and find ways to help themselves after a disaster, however, will be better able to recover long-term from mental health effects

DRUGS REGULATORY UNIT | NOVEMBER 2009 | SECOND EDITION
Protocol and preliminary evaluationas of Jan 17, 2020
Introduction The novel Coronavirus (nCoV) epidemic in 2019 -2020 has recently emerged. The route of transmission is not totally known, although it is known that it can spread from person to person, and local health care systems may be ill-equipped to handle a large-scale outbreak. Furthermore, misco...nceptions and misinformation about the disease often spreads rapidly in such epidemics.
In previous epidemics mental health and psychosocial support (MHPSS) has been identified as a key priority. MHPSS ensures the well-being of the affected populations, and counter-acts the threats to public health and safety that fear, stigmatization and misconception pose. Access to information, knowledge about the disease and how it spreads, make it easier for the affected to feel supported and calm, and to comply with instructions. Furthermore, psychosocial support to staff and volunteers help the operation as work conditions are extremely stressful.
This briefing note provides background knowledge on the MHPSS aspects related to nCoV and suggests MHPSS activities that can be implemented. The messages can be helpful for those in contact with patients or relatives and feel the strain of working and living during the epidemic. The briefing is aimed both at those working in any capacity with those affected by nCoV and for the MHPSS responders who implement MHPSS activities and interventions for everyone affected.
