Nat Commun 9, 5370 (2018). https://doi.org/10.1038/s41467-018-07804-8. Mycobacterium ulcerans is the causative agent of Buruli ulcer, a neglected tropical skin disease that is most commonly found in children from West and Central Africa. Despite the severity of the infection, therapeutic options are... limited to antibiotics with severe side effects. Here, we show that M. ulcerans is susceptible to the anti-tubercular drug Q203 and related compounds targeting the respiratory cytochrome bc1:aa3. While the cytochrome bc1:aa3 is the primary terminal oxidase in Mycobacterium tuberculosis, the presence of an alternate bd-type terminal oxidase limits the bactericidal and sterilizing potency of Q203 against this bacterium. M. ulcerans strains found in Buruli ulcer patients from Africa and Australia lost all alternate terminal electron acceptors and rely exclusively on the cytochrome bc1:aa3 to respire. As a result, Q203 is bactericidal at low dose against M. ulcerans replicating in vitro and in mice, making the drug a promising candidate for Buruli ulcer treatment.

There is paucity of data on the burden and specific drivers operative in the pathogenesis of chronic obstructive pulmonary disease (COPD) in the African setting and populations. Lack of awareness and inadequate knowledge on the aetio-pathogenesis of the disease together with inadequate capacity for ...COPD care contributes to preventive and management challenges. Thus, the majority of patients with COPD are misdiagnosed, misclassified and mismanaged or undertreated. With the struggling improvement in the quality of healthcare in Africa, studies conducted over the last 10 years indicates the rising trends in both the risk factors and the burden of COPD. The role of new risk factors such as indoor pollution, infections with human immunodeficiency virus (HIV) and pulmonary tuberculosis (TB), in the pathogenesis of COPD in Africa is increasingly being recognized. This literature review attempts to collect and synthesize information that could be useful in improving COPD care and informing the governments to take appropriate actions for prevention, diagnosis and management of COPD in Africa.

There is increasing interest in understanding the role of air pollution as one of the greatest threats to human health worldwide. Nine of 10 individuals breathe air with polluted compounds that have a great impact on lung tissue. The nature of the relationship is complex, and new or updated data are... constantly being reported in the literature. The goal of our review was to summarize the most important air pollutants and their impact on the main respiratory diseases (chronic obstructive pulmonary disease, asthma, lung cancer, idiopathic pulmonary fibrosis, respiratory infections, bronchiectasis, tuberculosis) to reduce both short- and the long-term exposure consequences. We considered the most important air pollutants, including sulfur dioxide, nitrogen dioxide, carbon monoxide, volatile organic compounds, ozone, particulate matter and biomass smoke, and observed their impact on pulmonary pathologies. We focused on respiratory pathologies, because air pollution potentiates the increase in respiratory diseases, and the evidence that air pollutants have a detrimental effect is growing. It is imperative to constantly improve policy initiatives on air quality in both high- and low-income countries.

In 2017, $37.4 billion of development assistance was provided to low- and middleincome countries to maintain or improve health. This amount is down slightly compared to 2016, and since 2010, development assistance for health (DAH) has grown at an annualized rate of 1.0%. While global development ass...istance for health has seemingly leveled off, global health spending continues to climb, outpacing economic growth in many countries. Total health spending for 2015, the most recent year for which data are available, was estimated to be $9.7 trillion (95% uncertainty interval: 9.7–9.8)*, up 4.7% (3.9–5.6) from the prior year, and accounted for 10% of the world’s total economy. With some sources of health spending growing and other types remaining steady, and with major variations in spending from country to country, it is more important than ever to understand where resources for health come from, where they go, and how they align with health needs. This information is critical for planning and is a necessary catalyst for change as we aim to close the gap on the unfinished agenda of the Millennium Development Goals (MDGs) and move forward toward universal health coverage (UHC) in the Sustainable Development Goals (SDGs) era.

Diphtheria is caused by Corynebacterium species, mostly by toxin-producing Corynebacterium diphtheriae and rarely by toxin-producing strains of C. ulcerans and C. pseudotuberculosis. The most common type of diphtheria is classic respiratory diphtheria, whereby the exotoxin produced characteristicall...y causes the formation of a pseudomembrane in the upper respiratory tract and damages other organs, usually the myocardium and peripheral nerves. Acute respiratory obstruction, acute systemic toxicity, myocarditis and neurologic complications are the usual causes of death. The infection can also affect the skin (cutaneous diphtheria). More rarely, it can affect mucous membranes at other non-respiratory sites, such as genitalia and conjunctiva.
C. diphtheriae is transmitted from person to person by intimate respiratory and direct contact; in contrast, C. ulcerans and C. pseudotuberculosis are zoonotic infections, not transmitted person-to-person. The incubation period of C. diphtheriae is two to five days (range 1– 10 days). A person is infectious as long as virulent bacteria are present in respiratory secretions, usually two weeks without antibiotics, and seldom more than six weeks. In rare cases, chronic carriers may shed organisms for six months or more. Skin lesions are often chronic and infectious for longer periods. Effective antibiotic therapy (penicillin or erythromycin) promptly terminates shedding in about one or two days.

The greatest risk to persons engaging in international medical emergency response is poor preparation.
The In Control handbook hopes to provide a remedy.
At the time of writing, we are living through the Coronavirus (COVID-19) pandemic, a health emergency that disregards physical borders, brin...gs into focus social inequalities and affects people on every continent. This shared challenge requires unprecedented measures and the collaboration of the brightest minds to support global health protection through this crisis and beyond. Healthcare infrastructures have to be strengthened, public health capacities and processes upgraded, medical countermeasures and vaccinations found and psychosocial side-effects treated.
Solidarity is the normative order of the day and the human species has to collaborate to face this invisible threat. Hiding and living in fear is not an option in this interconnected world. We have both a responsibility and an opportunity to make substantial contributions to a safer, healthier and more sustainable future for us all.
The existence of this handbook is an impressive example of solidarity. Over 50 authors from more than 15 institutes and organisations have come together voluntarily within a very short time to make their expertise available and enable cross-sectoral thinking. Knowledge is bundled, resources are combined, information gaps are filled. The In Control handbook is not a theoretical treatise of possible dangers, but a collection of subject-matter expertise, written by experts and practitioners who have shaped health topics over the past 20 years in the most diverse corners of the world.
The Centre for International Health Protection at the Robert Koch Institute (RKI) is collaborating with its partners and investing heavily in the build-up of operational know-how and capacity to support health crisis response abroad. This is done by preparing and enabling professionals to deploy safely across the world to assist those in need. In Control addresses the multi-faceted challenges of an international deployment. Readers will find not only technical medical information, but also insights into, for example, the fragility of our environment, the cultural differences that influence risk communication or the dilemmas arising from social distancing. Legal principles are highlighted, along with ethical guidance to ensure that our actions and decisions correspond to the highest moral standards.

La filariose lymphatique (FL) est une maladie évitable, incapacitante et défigurante, due à une infestation par des filaires parasites des espèces Wuchereria bancrofti, Brugia malayi et B. timori. On estime que 51,4 millions de personnes sont infectées dans le monde. Le lymphœdème et l’hydr...ocèle sont les conséquences cliniques chroniques visibles de l’altération des vaisseaux lymphatiques causée par la présence de
ces parasites dans l’organisme. Les parasites sont transmis d’une personne à l’autre par l’intermédiaire de moustiques des genres Culex, Anopheles, Mansonia et Aedes. L’année 2020 a marqué la 20e année du Programme mondial pour l’élimination de la filariose lymphatique (GPELF) établi par l’OMS, dont l’objectif est de mettre fin à la transmission de l’infection grâce à l’administration de masse de médicaments
(AMM) et d’alléger les souffrances des malades par la prise en charge de la morbidité et la prévention des incapacités (PMPI).

Over the past twenty years, huge efforts made by a broad coalition of stakeholders curbed the last epidemic and brought the disease to the brink of elimination. In this paper, the latest figures on disease occurrence, geographical distribution and control activities are presented. Strong evidence in...dicates that the elimination of sleeping sickness ‘as a public health problem’ by 2020 is well within reach. In particular, fewer than one thousand new cases were reported in 2018, and the area where the risk of infection is estimated as moderate, high or very high has shrunk to less than 200,000 km2. More than half of this area is in the Democratic Republic of the Congo. The interruption of transmission of the gambiense form, targeted by the World Health Organization (WHO) for 2030, will require renewed efforts to tackle a range of expected and unexpected challenges. The rhodesiense form of the disease represents a small part of the overall HAT burden. For this form, the problem of under detection is on the rise and, because of an important animal reservoir, the elimination of disease transmission is not envisioned at this stage.

Conflicts and disasters, including pandemics, affect women and men in all their diversity differently, and women and girls often suffer the most. Crisis-related hardships combine and compound pre-existing disadvantages, for example, they often cause women’s working conditions to worsen while incre...asing their overall workload and care responsibilities. At the same time, crises can give rise to changes that enable women to take up roles that were previously available only to men, and crises can open opportunities to address existing gender-based discrimination and violations of rights.

Although Shiga toxin-producing Escherichia coli (STEC) have been isolated from a variety of food production animals, they are most commonly associated with ruminants from which we derive meat and milk. Because of the widespread and diverse nature of ruminant-derived food production, coupled with the... near ubiquity of STEC worldwide, there is no single definitive solution for controlling STEC that will work alone or in all situations. Instead, the introduction of multiple interventions applied in sequence, as a “multiple-hurdle scheme” at several points throughout the food chain (including processing, transport and handling) will be most effective.
This report summarizes the review and evaluation of interventions applied for the control of STEC in cattle, raw beef and raw milk and raw milk cheese manufactured from cows’ milk, and also evaluates available evidence for other small ruminants, swine and other animals. The information is presented from primary production, to the end of processing, providing the reader with information on the currently available interventions based on the latest scientific evidence.
This work was undertaken to support the development of guidelines for the control of STEC in beef, raw milk and cheese produced from raw milk by the Codex Committee on Food Hygiene (CCFH).
