Chromoblastomycosis (CBM), represents one of the primary implantation mycoses caused by melanized fungi widely found in nature. It is characterized as a Neglected Tropical Disease (NTD) and mainly affects populations living in poverty with significant morbidity, including stigma and discrimination.
Mycetoma is a specific chronic, granulomatous, inflammatory disease. It usually involves the subcutaneous tissue, most probably after traumatic inoculation of the causative organism. It has a prolonged, progressive, and indolent course, and, if untreated, it ultimately leads to destruction of the de...eper tissues and bone, resulting in deformity and disability that may necessitate amputation of the affected parts with all the social and economic implications of this. The disease is characterized by tumefaction, draining sinuses, and the presence of grains.

Most neglected tropical diseases (NTDs) occur in remote areas of low- and middle-income countries, where health systems are often poorly developed. Therefore, these neglected patients generally lack access to quality preventive, diagnostic, and therapeutic care [1]. The difficulty to access NTD-ende...mic areas, challenging logistics, and the lack of skilled human resources in these areas are also major obstacles to conduct clinical research. We had to face these when conducting a good clinical practice/good clinical laboratory practice (GCP/GCLP)-compliant clinical study in eastern Sudan, a well-known endemic area for visceral leishmaniasis and other NTDs. We share here the challenges related to study preparation and implementation of this GCP/GCLP study that investigated the causes of persistent fever in a rural hospital located in Gedaref State in eastern Sudan. We think this type of paper may be of interest for researchers planning to conduct a clinical trial in a resource-limited setting as well as for funders of such research.

Mycetoma is a chronic infectious disease of the subcutaneous tissue with a high morbidity. This disease has been reported from countries between 30°N and 15°S since 1840 but the exact burden of disease is not known. It is currently unknown what the incidence, prevalence and the number of reported ...cases per year per country is. In order to estimate what the global burden of mycetoma is, a meta-analysis was performed. In total 50 studies were included, which resulted in a total of 8763 mycetoma cases. Most cases were found in men between 11 and 40 years of age. The foot was most commonly affected.

The purpose of this guide is to provide practical advice for health staff undertaking infectious disease preparedness and response activities to ensure that access to safe abortion care (SAC) is maintained when an infectious disease outbreak occurs. It is an operational guide which can serve to supp...ort health actors to maintain SAC services during outbreaks and ensure that necessary SAC considerations are integrated within outbreak responses; it is not a clinical guide. The locational focus of this document is humanitarian and fragile settings; however, recommendations may apply to infectious disease outbreaks in all low-resource populations. This guide is intended to complement Sexual and Reproductive Health and Rights During Infectious Disease Outbreaks: Operational Guidance for Humanitarian and Fragile Settings.

Snakebite is an acute life threatening time limiting medical emergency. It is a preventable public
health hazard often faced by rural population in tropical and subtropical countries with heavy
rainfall and humid climate.
El desarrollo, desde 1991, de las Iniciativas Subregionales de Control de la Enfermedad de Chagas, y los avances de conocimiento en materia de diagnóstico y manejo de la infección/enfermedad de Chagas, llevan a la necesidad ética, y operativamente imperiosa, de estructurar el diagnóstico, atenci...ón y tratamiento de esta afección.
Una situación particularmente delicada, preocupante y alarmante, se constituye por la escasa einequitativa disponibilidad de los limitados recursos terapéuticos, actualmente disponibles, para el tratamiento etiológico de Chagas, en la mayor parte de los países endémicos de América.
En esta situación, se propone el desarrollo de la Consulta técnica regional OPS/MSF sobre organización y estructura de la atención médica del enfermo e infectado por Trypanosoma cruzi (enfermedad de Chagas), con los objetivos de:
- definir el alcance y estructura de la atención médica al paciente, tanto en diagnóstico, manejo como tratamiento;
- desarrollar modelos alternativos y optativos de atención, asimilables a las estructurassanitarias de los países;
- delinear la atención del chagásico, según su momento biológico-patológico evolutivo,dentro de los niveles de complejidad de la atención médica;
- establecer consideraciones sobre la atención pediátrica, materno-infantil, transfusional y mayor complejidad;
- definir las necesidades y alcances del diagnóstico de la enfermedad;
- establecer los alcances y facilidades que, dentro de los sistemas de atención, deben poseer estos pacientes;
- definir el panorama total de disponibilidad y accesibilidad de los pacientes al tratamiento etiológico de esta dolencia;
- proyectar conceptos y concepciones marco sobre el costo, impacto y efectividad del
desarrollo de este componente de morbilidad y atención en enfermedad de Chagas; y
- establecer las necesidades de investigación operativa y de gestión para avanzar en el
desarrollo de la atención médica a este grupo de pacientes.
Esta consulta, desarrollada en la ciudad de Montevideo, el 13 y 14 de octubre de 2005, pretende marcar la elaboración de una guía conceptual para comentarla y diseminarla en el año 2006, desde las cinco Iniciativas Intergubernamentales Subregionales de Control de Enfermedad de Chagas.

Report of the third conference organized with ICONZ, DFID-RIU, Gates Foundation,
SOS, EU, TDR and FAO with the participation of ILRI and OIE
WHO headquarters, Geneva, Switzerland
23–24 November 2010
In this report we have tried to present the various issues, problems and
challenges that ...were discussed against the backdrop of the many inspiring
control programmes that were presented. Again and again these programmes
demonstrated how the NZDs are not so much re-emerging as rediscovered
– once a concerted effort is made to fi nd and treat patients – and how both
control and prevention rely on involving and inspiring the animal keeping
communities where they prevail.

The objectives of the meeting were:
1. To step up the commitment of national authorities and technical and financial partners toWHO’s elimination objective for g-HAT.
2. To share achievements, challenges and views on the elimination goal among countries and implementing partners.
3. To assess t...he status of critical technical aspects to be solved in research and development of drugs and diagnostic tools, epidemiology, vector control and animal reservoirs.
4. To define the mechanisms for strengthening and organizing collaboration and coordination among stakeholders.
more
The objectives of the meeting were:
1. To update the current status of the disease transmission, country capacities and plans for tackling the disease.
2. To understand the epidemiology including disease distribution and risk, the models
for estimating under-detection, the geographical variati...ons of in clinical presentation,
the roles of domestic and wild animal reservoirs and the subsequent different
transmission patterns and control approaches, including vector control.
3. To update current research and development efforts for improving diagnostic and
treatment tools.
4. To define the goals for achieving the control of r-HAT, the need for a multisectoral
approach and to discuss the strategy for controlling r-HAT and the coordination
mechanisms.

TDR (Tropical Disease Research) Annual Report 2018
Les progrès remarquables réalisés dans la lutte contre la forme à T. b. gambiense reposent sur le dépistage et le traitement curatif, une stratégie qui interrompt la transmission en réduisant le réservoir de parasites chez l’être humain. Parfois, cette
approche a été combinée avec des... activités de lutte antivectorielle. L’objet de ces lignes directrices est donc de la plus haute importance pour la poursuite des progrès en vue de l’élimination de la THA.

Wiping out Trachoma from Nepal – How Nepal eliminated trachoma as a public health problem
WHO - 2018
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.

The major neglected tropical diseases, Taenia solium taeniosis/cysticercosis and schistosomiasis caused by Schistosoma mansoni or S. haematobium are presumed to be widely distributed in Africa. Taenia solium taeniosis/ cysticercosis has been reported as an emerging disease in different regions of Af...rica [1, 2], but currently the exact distribution remains unclear. Reported prevalences of T. solium taeniosis and cysticercosis in African countries are not extensive and are further complicated by the lack of ‘gold standard’ tests for diagnosis.

Schistosomiasis is widely recognized as a disease that is socially determined. An
understanding of the social and behavioural factors linked to disease transmission and
control should play a vital role in designing policies and strategies for schistosomiasis
prevention and control. To this must b...e added the awareness that schistosomiasis is
also a disease of poverty. It still survives in poverty-stricken, remote areas where there
is little or no safe water or sanitation, and health care is scarce or non-existent. For
a variety of complex reasons, many of which are addressed in this book, the disease
is particularly prevalent in sub-Saharan Africa, and persists in certain areas of rural
China. This concern for human behaviour in an environment of poverty echoes the
concerns of the new research priority for “diseases of poverty” identified by the
Special Programme for Research & Training in Tropical Diseases.

Rabies is fatal, vaccine-preventable disease responsible for an estimated 59,000 human deaths each year. Most cases are transmitted by dogs, and most deaths occur in underserved populations in Africa and Asia. Approximately 40% of deaths occur in children.
Rabies is entirely preventable, and vaccines, medicines, tools and technologies have long been available to prevent people from dying of dog-mediated rabies. Nevertheless, rabies still kills about 60 000 people a year, of whom over 40% are children under 15, mainly in rural areas of economically dis...advantaged countries in Africa and Asia. Of all human cases, up to 99% are acquired from the bite of an infected dog.

Rabies is a disease of animals but too often the outcome is gauged in terms of human suffering and
death. Despite this, in areas of the world where rabies is endemic there is often a lack of communication between veterinary and medical professionals, to the extent that the disease continues to thri...ve and potential victims are not treated. The problem is partly
exacerbated by a lack of awareness and experience of the disease and of what to do when confronted by suspect cases. In these technologically advanced days, although it is possible to learn “all there is to know” about almost any subject, it is sometimes difficult to distil the essence.

Leishmaniases are a group of diseases of zoonotic importance caused by over 20 species of protozoa of the genus Leishmania, in which domestic dogs are considered to be the main reservoir for the disease. However, the involvement of other vertebrates as reservoirs for these parasites has also been in...vestigated. Therefore, the objective of the present study was to carry out a systematic review with meta-analysis on occurrences of leishmaniasis in equids. The case reports described animals with cutaneous symptoms of leishmaniasis (papules, nodules, ulcers or crusts) that regressed spontaneously, located mainly on the head and limbs, from which three species of protozoa were identified in the lesions: Leishmania braziliensis, Leishmania infantum and Leishmania siamensis. In turn, the meta-analysis showed a combined prevalence of 25%, although with high heterogeneity among the studies, which was attributed to the use of different methods for diagnosing the disease. Leishmaniasis in equids is a benign disease but it should be included in the differential diagnosis of cutaneous diseases among these species. Seroepidemiological studies are important in investigating and monitoring suspected exposure of these hosts to the parasite, especially in endemic areas. However, there is also a need to standardize diagnostic methods.
