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.

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.

Dengue fever is a mosquito-borne tropical disease caused by the dengue virus. Symptoms typically beg...in three to fourteen days after infection. This may include a high fever, headache, vomiting, muscle and joint pains, and a characteristic skin rash.Recovery generally takes two to seven days. In a small proportion of cases, the disease develops into the life-threatening dengue hemorrhagic fever, resulting in bleeding, low levels of blood platelets and blood plasma leakage, or into dengue shock syndrome, where dangerously low blood pressure occurs.
Dengue is spread by several species of mosquito of the Aedes type, principally A. aegypti.The virus has five different types;infection with one type usually gives lifelong immunity to that type, but only short-term immunity to the others. Subsequent infection with a different type increases the risk of severe complications. A number of tests are available to confirm the diagnosis including detecting antibodies to the virus or its RNA.

Cotonou Declaration oBuruli Ulcer
Cotonou, Benin, 30 March 2009
Neglected tropical diseases kill, weaken or incapacitate millions of people every year, causing permanent physical suffering, social stigmatization and reduced productive capacity. Buruli ulcer, one such disease, causes immense suffer...ing and disabilities, especially among children. Delayed schooling and loss of productivity are considerable among the affected populations. These adverse consequences tend to aggravate poverty in affected communities. Globally, the disease has been reported in 30 countries. In WHO’s African Region, Buruli ulcer has been confirmed in 12 countries and is suspected in 10 others.
Significant progress has been made in the past 10 years in knowledge of Buruli
ulcer, investments in related research, control of the disease, and improvement
of tools for case diagnosis and development of treatment protocols. Substantial achievements have been made in diagnosis, treatment, immunology and epidemiology. Despite these achievements, little is known about the exact mode of transmission of the disease, and there is no simple diagnostic test usable in the field.
The use of antibiotics has revolutionized treatment and contributed to reducing the need for surgery by half. However, efforts are still needed to develop simple diagnostic tools usable in the field as well as disability prevention methods. The Global Buruli Ulcer Initiative has adopted the strategy recommended by WHO. The strategy is based on early diagnosis of the disease and the use of antibiotics for treatment upon the onset of the first signs by improving access to screening and case management at the most peripheral level of the health system.

L’ulcère de Buruli, une infection causée par Mycobacterium ulcerans, touche plus de 33 pays dans le monde, mais un peu moins de la moitié seulement de ces pays communiquent régulièrement des données sur la maladie à l’OMS. La plupart des cas notifiés se trouvent dans les sous-régions d...Afrique occi-
dentale et centrale. Le mode de transmission de l’ulcère de Buruli n’est pas connu. Environ la moitié des personnes touchées sont des enfants de moins de 15 ans et les deux sexes sont concernés à parts égales.
Le diagnostic repose principalement sur l’observation des caractéristiques cliniques et épidémiologiques.
Parmi les quatre méthodes de confirmation utilisées (examen microscopique, amplification en chaîne par polymérase (PCR), histopathologie et mise en culture), la PCR est la plus rapide et la plus courament employée. D’autres méthodes rapides, comme l’utilisation de la chromatographie sur couche mince par fluorescence pour détecter la mycolactone dans les lésions des cas suspects d’ulcère de Buruli, sont actuellement à l’étude dans quatre pays d’Afrique. Des travaux de recherche sont en cours pour mettre au
point des tests utilisables sur le lieu des soins. Le traitement de l’ulcère de Buruli consiste à administrer une association d’antibiotiques (rifampicine et clarithromycine) pendant 8 semaines. Des traitements complémentaires, comme le soin des plaies, les greffes cutanées et la prévention des incapacités, sont nécessaires dans certains cas pour parvenir à une guérison complète.
La cible fixée par l’Organisation mondiale de la Santé (OMS) exigée des pays pour assurer la lutte contre l’ulcère de Buruli est la confirmation d’au moins 70 % des cas par PCR pour chaque pays. Tous les pays d’endémie disposent d’au moins un établissement doté des moyens nécessaires pour effectuer les tests de PCR pour la confirmation des cas. Cependant, la plupart des pays de la Région africaine n’ont pas réussi à atteindre la cible fixée. Un déclin du taux de confirmation a même été observé.

In sub-Saharan Africa (SSA), urgent action is needed to curb a growing crisis in cancer incidence and mortality.
Without rapid interventions, data estimates show a major increase in cancer mo...rtality from 520 348 in 2020 to about
1 million deaths per year by 2030. Here, we detail the state of cancer in SSA, recommend key actions on the basis of
analysis, and highlight case studies and successful models that can be emulated, adapted, or improved across the
region to reduce the growing cancer crises. Recommended actions begin with the need to develop or update national
cancer control plans in each country. Plans must include childhood cancer plans, managing comorbidities such as
HIV and malnutrition, a reliable and predictable supply of medication, and the provision of psychosocial, supportive,
and palliative care. Plans should also engage traditional, complementary, and alternative medical practices employed
by more than 80% of SSA populations and pathways to reduce missed diagnoses and late referrals. More substantial
investment is needed in developing cancer registries and cancer diagnostics for core cancer tests.

To guide One Health capacity building efforts in the Republic of Guinea in the wake of the 2014–2016 Ebola virus disease (EVD) outbreak, we sought to identify and assess the existing systems and structures for zoonotic disease detection and control. We partnered with the government ministries resp...onsible for human, animal, and environmental health to identify a list of zoonotic diseases – rabies, anthrax, brucellosis, viral hemorrhagic fevers, trypanosomiasis and highly pathogenic avian influenza – as the country's top priorities. We used each priority disease as a case study to identify existing processes for prevention, surveillance, diagnosis, laboratory confirmation, reporting and response across the three ministries. Results were used to produce disease-specific systems “maps” emphasizing linkages across the systems, as well as opportunities for improvement. We identified brucellosis as a particularly neglected condition. Past efforts to build avian influenza capabilities, which had degraded substantially in less than a decade, highlighted the challenge of sustainability. We observed a keen interest across sectors to reinvigorate national rabies control, and given the regional and global support for One Health approaches to rabies elimination, rabies could serve as an ideal disease to test incipient One Health coordination mechanisms and procedures. Overall, we identified five major categories of gaps and challenges: (1) Coordination; (2) Training; (3) Infrastructure; (4) Public Awareness; and (5) Research. We developed and prioritized recommendations to address the gaps, estimated the level of resource investment needed, and estimated a timeline for implementation. These prioritized recommendations can be used by the Government of Guinea to plan strategically for future One Health efforts, ideally under the auspices of the national One Health Platform. This work demonstrates an effective methodology for mapping systems and structures for zoonotic diseases, and the benefit of conducting a baseline review of systemic capabilities prior to embarking on capacity building efforts.

DHS Methodological Report No. 20
This study used Service Provision Assessment (SPA) and Demographic and Health Survey (DHS) data from Haiti, Malawi, and Tanzania to compare traditionally used additive methods with a data reduction method—principal component analysis (PCA).
We scored ...the quality of health facilities with three approaches (simple additive, weighted additive, and PCA) for two constructs: quality of services, with only facilities-level data, and quality of care, which incorporates observation and client data. We ranked facilities as high, medium, or low quality based on their scores. Our results indicated that the rankings change with the scoring methodology. There was more consistency in the rankings of facilities by the simple additive and PCA methods than the weighted additive and PCA-based rankings. This may be due to the low factor loadings and little variance explained by the first component in the PCA. We aggregated facility scores to their respective DHS clusters (Haiti, Malawi) or regions (Tanzania) and geographically linked them to women interviewed in DHS surveys to test associations between the use of family planning services and the quality environment, as measured with each index.
