• Leptospirosis is a disease that is caused by
spirochete bacteria in the genus Leptospira.
There are 10 pathogenic species, and more
than 250 pathogenic serovars.
• While leptospirosis occurs worldwide, it is
more common in tropical or sub-tropical
climates.
Chromoblastomycosis (CMB) is a chronic fungal infection of the skin and the subcutaneous tissue caused by a transcutaneous traumatic inoculation of a specific group of dematiaceous fungi occurring mainly in tropical and subtropical zones worldwide. If not diagnosed at early stages, patients with CBM... require long term therapy with systemic antifungals, sometimes associated with physical methods. Unlike other neglected endemic mycoses, comparative clinical trials have not been performed for this disease. Nowadays, therapy is based on a few open trials and on expert opinion. Itraconazole either as monotherapy or associated with other drugs, or with physical methods, is widely used. Recently, photodynamic therapy has been successfully employed in combination with antifungals in patients presenting with CBM. In the present revision the most used therapeutic options against CBM are reviewed as well as the several factors that may have impact on the patient's outcome.

Human scabies is caused by an infestation of the skin by the human itch mite (Sarcoptes scabiei var. hominis). The microscopic scabies mite burrows into the upper layer of the skin where it lives and lays its eggs.
Scabies is found worldwide and affects people of all races and social classes. Scabi...es can spread rapidly under crowded conditions where close body and skin contact is frequent. Institutions such as nursing homes, extended-care facilities and prisons are often sites of scabies outbreaks. Child care facilities also are a common site of scabies infestations.

Scabies is a skin infection that is a result of direct skin to skin contact and is primarily mediated by close and extended contact with scabies infested person. Scabies occurs worldwide among people of all ages, races, genders and social classes and has been identified as a neglected tropical infec...tious disease. Globally, it affects more than 130 million people at any time.

Scabies is an itchy skin condition caused by a tiny burrowing mite. This eight-legged bug is so small which makes it hard to see on the skin. Approximately 300 million cases of scabies are reported worldwide each year.
Children are at high risk of dog bites and contracting rabies. Forty percent of reported rabies cases worldwide are children under the age of fifteen. In our project areas, the proportion of children dying is often even higher. Rabies most often persists in poor communities and rural regions of deve...loping countries in Africa and Asia. If the risks are widely understood and appropriate dog bite treatment is well known – rabies is 100% preventable.

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.

Background: The human helminth infections include ascariasis, trichuriasis, hookworm infections, schistosomiasis, lymphatic filariasis (LF) and onchocerciasis. It is estimated that almost 2 billion people worldwide are infected with helminths. Whilst the WHO treatment guidelines for helminth infecti...ons are mostly aimed at controlling morbidity, there has been a recent shift with some countries moving towards goals of disease elimination through mass drug administration, especially for LF and onchocerciasis. However, as prevalence is driven lower, treating entire populations may no longer be the most efficient or cost-effective strategy. Instead, it may be beneficial to identify individuals or demographic groups who are persistently infected, often termed as being “predisposed” to infection, and target treatment at them.
Methods: The authors searched Embase, MEDLINE, Global Health, and Web of Science for all English language, humanbased papers investigating predisposition to helminth infections published up to October 31st, 2017. The varying definitions used to describe predisposition, and the statistical tests used to determine its presence, are summarised. Evidence for predisposition is presented, stratified by helminth species, and risk factors for predisposition to infection are identified and discussed.
Results: In total, 43 papers were identified, summarising results from 34 different studies in 23 countries. Consistent evidence of predisposition to infection with certain species of human helminth was identified. Children were regularly found to experience greater predisposition to Ascaris lumbricoides, Schistosoma mansoni and S. haematobium than adults. Females were found to be more predisposed to A. lumbricoides infection than were males. Household clustering of infection was identified for A. lumbricoides, T. trichiura and S. japonicum. Ascaris lumbricoides and T. trichiura also showed evidence of familial predisposition. Whilst strong evidence for predisposition to hookworm infection was identified, findings with regards to which groups were affected were considerably more varied than for other helminth species.
Conclusion: This review has found consistent evidence of predisposition to heavy (and light) infection for certain human helminth species. However, further research is needed to identify reasons for the reported differences between demographic groups. Molecular epidemiological methods associated with whole genome sequencing to determine ‘who infects whom’ may shed more light on the factors generating predisposition.

Chagas disease is a neglected tropical disease caused by the protozoan parasite Trypanosoma cruzi. It is a significant public health problem, affecting millions of people worldwide. And although it was described 110 years ago, only two old nitroheterocyclic drugs, benznidazole and nifurtimox, are cu...rrently available for the treatment of Chagas disease and both have several limitations. Besides the clear unmet medical need, many challenges preclude the development of new treatments, some of them related to a lack of understanding of the pathophysiology of the disease and parasite-host interactions. New knowledge and tools are becoming available, but the number of new chemical entities progressing through the preclinical pipeline is inadequate. Therefore, it is still uncertain whether safe, effective and accessible new drugs will be available in the near future. The Chagas disease research community must commit to even greater collaboration to ensure that patients eventually benefit from better treatments.

Investing to overcome the global impact of neglected tropical diseases charts new ground in tackling the 17 neglected tropical diseases (NTDs) that aff ect more than a billion people in 149 countries worldwide. It makes the case for domestic investment to reach the targets of WHO’s Roadmap on NTDs... by 2020 and sustain enhanced, equitable access to high-quality coverage against these diseases to 2030.
Th is third WHO report anticipates the investments needed as countries graduate from
low-income to middle-income status and as the world’s focus expands from the Millennium Development Goals to the Sustainable Development Goals.

The recurrence of severe climate events combined with economic, social, and institutional fragilities leave El Salvador in an utterly critical humanitarian situation and highly vulnerable. Located in a disaster-prone subregion, El Salvador is among the 20 countries at the highest risk of disasters w...orldwide. The successive hydrometeorological hazards that impacted El Salvador over the past two years include tropical storms Amanda and Cristóbal and hurricanes Eta, Iota, and,
more recently, Julia. These storms profoundly affected the lives and livelihoods of almost 900 000 people and significantly disrupted health services, especially at the first level of care. In addition, the country’s exposure to earthquakes, floods, and droughts is also constant. Infrastructural and institutional limitations to deal with emergencies and
low capacity to respond to adverse events are an additional challenge, which leaves the population—particularly the most vulnerable—at even higher risk.

Japan has been implementing projects of global extension of medical technologies under an official development assistance policy to improve public health and medicine by promoting Japanese medical technologies worldwide. The current work examines the impact and goals of implementing this new scheme.... The scheme has involved dozens of projects that sent Japanese experts to partner countries and that invited their counterparts to Japan to showcase Japanese medical technologies. Approximately 50 projects have been implemented in 24 countries over 5 years, and 19,638 individuals have been trained. As a result, the introduced technology was adopted in national guidelines in 4 projects and the introduced equipment was procured in the partner country in 17 projects. In total, 912,334 individuals have benefitted from the introduction of these medical technologies. The concept of "creating shared value" (CSV) could help promote project success by both creating economic value and encouraging social progress. However, the sustainability of that business model remains in question in terms of the internationalization of CSV. Several successful projects improved medical care and led to new business opportunities.

Issue Brief 33: Since 21 June 2023, 57 024 new cholera cases, including 399 new death have been reported worldwide (European Center for Disease Prevention and Control). In total, 25 countries have reported cases since the beginning of 2023. The major underlying causes of potential outbreaks are poor... environmental infastructure, lack of health care services, lack of save water and sanitation as well as increase population movement. Climate change becomes an additional trigger, as extreme climate events like cyclones,floods and droughts reduce access to clean water and create an ideal environment for cholera to thrive. The overall capacity to respond to the multiple outbreaks is obstructed by a global lack of resources.
This issue brief provides an overview of the current outbreaks, treatment guidelines, information material, countries strategies and more.

Cholera is a transmissible diarrhoeal infection caused by Vibrio cholerae. Endemic and/or epidemic in over 40 countries (mainly in Africa and Asia), cholera continues to be a major global public health issue.
The World Health Organization (WHO) estimates that the number of cases reported worldwid...e represents in reality only 5 to 10% of actual cases.
This guide is intended for medical and non-medical staff responding to a cholera outbreak. It attempts to provide concrete answers to the questions and problems faced by staff, based on the recommendations of reference organisations, such as WHO and UNICEF, as well as Médecins Sans Frontières’ experience in the field.
It is divided into 8 chapters. Chapter 1, Cholera overview, outlines the epidemiological and clinical features of cholera. Chapter 2, Outbreak investigation, explains the method and stages of a field investigation, from the alert to implementation of initial activities. Chapter 3, Cholera control measures, details measures and tools to prevent and/or control cholera transmission and mortality in populations affected, or at risk of being affected, by an epidemic (curative care, prevention means and health promotion activities). Chapter 4, Strategies for epidemic response, addresses the roll-out strategies of the measures described in Chapter 3 which depend on context (e.g. urban, rural, endemic, non-endemic setting, etc.), resources and particular constraints. Chapter 5, Cholera case management, details the different stages of cholera treatment, from diagnosis through to cure.
Chapter 6, Setting up cholera treatment facilities, focuses on the installation of treatment facilities that vary in size and complexity according to operational requirements (treatment centres and units and oral rehydration points). Chapter 7, Organisation of cholera treatment facilities, describes the organisation of these specialized facilities in terms of human resources, supply, water, hygiene and sanitation, etc. Chapter 8, Monitoring and evaluation, presents the key data to be collected and analysed during an epidemic to facilitate a tailored response and evaluate its quality and effectiveness.
The guide includes various practical tools in the appendices to facilitate activities (e.g. water quality tests, job descriptions, documents, etc.). Moreover, the toolbox also contains additional tools in editable formats (individual patient file, cholera case register, pictograms).
Despite all efforts, it is possible that certain errors may have been overlooked in this guide. Please inform the authors of any errors detected.
