Abstract: Chagas disease is caused by infection with the protozoan Trypanosoma cruzi, and although over 100 years have passed since the discovery of Chagas disease, it still presents an increasing problem for global public health. A plethora of information concerning the chronic phase of human Chaga...s disease, particularly the severe cardiac form, is available in the literature. However, information concerning events during the acute phase of the disease is scarce. In this review, we will discuss the current status of acute Chagas disease cases globally, the immunological findings related to the acute phase and their possible influence in disease outcome, and reactivation of Chagas disease in immunocompromised individuals, a key point for transplantation and HIV invection management.

Context and impact of the crisis
A year after the signing of the Revitalized Agreement on the Resolution of the Conflict in South Sudan (R-ARCSS),1 the ceasefire holds in most parts of the country. Armed conflict between State security forces and opposition armed groups has been contained to a sma...ll number of areas in the Equatorias where Government forces continue to clash with non-signatories to the agreement. Many areas are seeing intra- and inter-communal violence, enabled by small-arms proliferation and weak rule of law. This is often driven by resource scarcity in areas that have experienced years of severe food insecurity.

Individual psychological help for adults impaired by distress in communities exposed to adversity.
The manual describes a scalable psychological intervention called Problem Management Plus (PM+) for adults impaired by distress in communities who are exposed to adversity. Aspects of Cognitive Behavi...oural Therapy (CBT) have been changed to make them feasible in communities that do not have many specialists. To ensure maximum use, the intervention is developed in such a way that it can help people with depression, anxiety and stress, whether or not exposure to adversity has caused these problems. It can be applied to improve aspects of mental health and psychosocial well-being no matter how severe people’s problems are.

During the past five decades, the incidence of dengue has increased 30-fold. Some 50–100 million new infections are estimated to occur annually in more than 100 endemic countries, with a documented further spread to previously unaffected areas; every year hundreds of thousands of severe cases ari...se, including 20 000 deaths; 264 disability-adjusted life years per million population per year are lost , at an estimated cost for ambulatory and hospitalized cases of US$ 514–1394, often affecting very poor populations. The true numbers are probably far worse, since severe underreporting and misclassification of dengue cases have been documented.

This document provides guidance on the application of non-pharmaceutical countermeasures to minimise the spread of the 2019 novel coronavirus (2019-nCoV) in the population. Some of the measures proposed refer specifically to certain phases of the epidemic (containment or mitigation phases), and can ...be adapted depending on the assessed severity/impact of the infection. Other measures are valid for all phases of an epidemic.
The guidance is based on the current knowledge of the 2019-nCoV and evidence available on other viral respiratory pathogens, mainly the Severe Acute Respiratory Syndrome coronavirus (SARS-CoV), the Middle East Respiratory Syndrome-related coronavirus (MERS-CoV) and seasonal or pandemic influenza viruses.

To support countries in adapting their response to different COVID-19 scenarios, the World Health
Organization (WHO) Department of Maternal, Newborn, Child and Adolescent Health and Ageing commissioned this scoping review of published and grey literature. The objective was to identify interventions... implemented to maintain the provision and use of essential services for MNCAAH during disruptive events and to summarize lessons learned during these interventions. The review included outbreaks of Ebola virus disease (EVD), severe acute respiratory syndrome (SARS), Zika virus disease (ZVD), the ongoing COVID-19 pandemic, and natural disasters and humanitarian emergencies that caused disruption to services, transport and other activities.

Today, the World Health Organization (WHO) is advancing the global fight against acute malnutrition in children under 5 with the launch of its new guideline on the prevention and management of wasting and nutritional oedema (acute malnutrition). This milestone is a crucial response to the persistent... global issue of acute malnutrition, which affects millions of children worldwide.
In 2015, the world committed to achieving the Sustainable Development Goals (SDGs), including the ambitious target of eliminating malnutrition in all of its forms by 2030. However, despite these commitments, the proportion of children with acute malnutrition has persisted at a worrying level, affecting an estimated 45 million children under five worldwide in 2022.
In 2022, approximately 7.3 million children received treatment for severe acute malnutrition (SAM). Although treatment coverage has increased, children with SAM in many of the worst affected countries are still unable to access the full necessary care for them to recover.
The Global Action Plan (GAP) on child wasting recognized the need for updated normative guidance to support governments in the prevention and management of acute malnutrition. WHO answered this call to action and developed a comprehensive guideline that provides evidence-based recommendations and good practice statements and will be followed by guidance and tools for implementation.

While epidemiological data for type 1 diabetes (T1D) in low/middle-income countries, and particularly low-income countries (LICs) including Liberia is lacking, prevalence in LICs is thought to be increasing. T1D care in LICs is often impacted by challenges in diagnosis and management. These challeng...es, including misdiagnosis and access to insulin, can affect T1D outcomes and frequency of severe complications. Despite the severe nature of T1D and growing burden in subSaharan Africa, little is currently known about the impact of T1D on patients and caregivers in the region. Methods We conducted a qualitative study consisting of interviews with patients with T1D, caregivers, providers, civil society members and a policy-maker in Liberia to better understand the psychosocial and economic impact of living with T1D, knowledge of T1D and selfmanagement, and barriers and facilitators for accessing T1D care.

Mpox continues to affect people around the world. A new framework released today by WHO will guide health authorities, communities and other stakeholders in preventing and controlling mpox outbreaks, eliminating human-to-human transmission of the disease, and reducing spillover of the virus from ani...mals to humans.
Mpox is a viral illness caused by the monkeypox virus (MPXV). It can cause a painful rash, enlarged lymph nodes and fever. Most people fully recover, but some get very sick. The virus transmits from person to person through close, including sexual, contact. It also has animal reservoirs in east, central and west Africa, where spillovers from animals to humans can occasionally occur, sparking further outbreaks.
There are two different clades of the virus: clade I and clade II. Clade I outbreaks are deadlier than clade II outbreaks.
A major emergence of mpox linked to clade II began in 2017, and since 2022, has spread to all regions of the world. Between July 2022 and May 2023, the outbreak was declared a Public Health Emergency of International Concern. While that outbreak has largely subsided, cases and deaths continue to be reported today, illustrating that low-level transmission continues around the world.
Currently, there is also a major outbreak of clade I virus in the Democratic Republic of the Congo (DRC), where cases have been on the rise for decades. Since the beginning of the year, over 6500 cases and 345 deaths have been reported in the DRC. Almost half of these are among children under the age of 15 years.
The Strategic framework for enhancing prevention and control of mpox (2024–2027) provides a roadmap for health authorities, communities, and stakeholders worldwide to control mpox outbreaks in every context, advance mpox research and access to countermeasures, and to minimize zoonotic transmission.

- Module 1: Understanding modelling approaches for sexual, reproductive, maternal, newborn, child and adolescent health, and nutrition
Coronavirus disease 2019 (COVID-19) has a wide range of documented effects. It directly causes death and disability for some people infected. However, disruption to... essential health services, resources allocated to mitigation and therefore away from essential health service delivery, and the overall impact on the economy and society must also be considered within the response to COVID-19. Understanding the magnitude of all of these effects is an essential part of developing mitigation polices.
Several epidemiological models have been created to assess the potential impact of disruptions to essential health services caused by COVID-19 on morbidity and mortality from conditions other than COVID-19 illness. This guide presents models that have been used to assess these indirect impacts. The effects have been studied in various settings, using a variety of models.
The guide is intended for people who need to understand what the models say, their construction and their underlying assumptions, or need to use models and their outcomes for planning and programme development and to support policy decisions for a country or region.

Interim guidance, 26 October 2021
This interim guidance has been developed on the basis of the advice issued by the Strategic Advisory Group of Experts (SAGE) on Immunization at its meeting on 5 October 2021.
SAGE said moderately and severely immunocompromised persons should be offered an addition...al dose of all WHO approved vaccines “since these individuals are less likely to respond adequately to vaccination following a standard primary vaccine series and are at high risk of severe COVID-19 disease.”
People aged 60 and older who received the Sinovac and Sinopharm vaccines should get a third dose too, the experts added, though use of other vaccines may also be considered depending on supply and access.
“When implementing this recommendation, countries should initially aim at maximizing 2-dose coverage in that population, and thereafter administer the third dose, starting in the oldest age groups”, they said.
SAGE has also reviewed a vaccine developed by Indian company Bharat Biotech and will issue a policy recommendation after WHO greenlights it for emergency use.

Biodiversity and Health in the Face of Climate Change pp 47–66
This chapter reviews the emerging importance of pollen allergies in relation to ongoing climate change. Allergic diseases have been increasing in prevalence over the last decades, partly as the result of the impact of climate change. ...Increased sensitisation rates and more severe symptoms have been the partial outcome of: increased pollen production of wind-pollinated plants resulting in long-term increased abundance of pollen in the air we breathe; earlier shifts of airborne pollen seasons making occurrence of allergic symptoms harder to predict and deal with efficiently; increased allergenicity of pollen causing more severe health effects in allergic individuals; introduction of new, invasive allergenic plant species causing new sensitisations; environment-environment interactions, such as plants and hosted microorganisms, i.e. fungi and bacteria, which comprise a complex and dynamic system, with additive, presently unforeseeable influences on human health; environment-human interactions, as the consequence of a combination of environmental factors, like air pollution, global warming, urbanisation and microclimatic variability, which create a multi-resolution spatiotemporal system that requires new processing technologies and huge data inflow in order to be thoroughly investigated. We suggest that novel, real-time, personalised pollen information services, like mobile-app risk alerts, must be developed to provide the optimum first line of allergy management.

World Psychiatry. 2010 Jun;9(2):67-77.
The main recommendations are presented in relation to: the need for coordinated policies, plans and programmes, the requirement to scale up services for whole populations, the importance of promoting community awareness about mental illness to increase levels ...of help-seeking, the need to establish effective financial and budgetary provisions to directly support services provided in the community. The paper concludes by setting out a series of lessons learned from the accumulated practice of community mental health care to date worldwide, with a particular focus on the social and governmental measures that are required at the national level, the key steps to take in the organization of the local mental health system, lessons learned by professionals and practitioners, and how to most effectively harness the experience of users, families, and other advocates

Latin America and the Caribbean is characterized by a matrix of social inequality whose axes —such as
socioeconomic stratum, gender, stage in the life cycle, ethnicity and race, territory, disability, and immigration
status— create multiple, often concurrent, situations of exclusion and discri...mination. The coronavirus
disease (COVID-19) pandemic has exacerbated wide social gaps and it is no coincidence that Latin America
and the Caribbean is one of the regions in which the health and socioeconomic impacts of the pandemic have
been the most severe, which shows that the costs of inequality are unsustainable

WHO recommends prompt recognition of progressive acute hypoxaemic respiratory failure when a patient with respiratory distress is failing to respond to standard oxygen therapy and adequate preparation to provide advanced oxygen/ventilatory support.
Hypoxaemic respiratory failure in ARDS commonly re...sults from intrapulmonary ventilation-perfusion mismatch or shunt and usually requires mechanical ventilation.
At any time, if there are urgent or emergent indications for intubation, do not delay.
WHO suggests that hospitalized patients with severe or critical COVID-19 with acute hypoxaemic respiratory failure that do not require emergent intubation be treated with HFNO, or CPAP or NIV (BiPAP) rather than standard oxygen therapy.
