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.

Two adjectives raise an issue for communicators working on Chagas disease (CD): “invisible and silent”. Two adjectives that can be ascribed to other neglected tropical diseases (NTD), but which are part of the essence of CD. Bringing CD out of its situation of neglect and oblivion is a mission e...ntrusted mainly to the world of communication as well as of science, politics and financial resources. However, communication has not always been considered among the priorities in the approach to the disease, except in valuable exceptions, some of which we have seen in the preceding article.

Dracunculiasis (Guinea worm disease), caused by the parasite Dracunculus medinensis, is traditionally acquired by drinking water containing copepods (water fleas) infected with D. medinensis larvae, but in recent years also appears increasingly to be transmitted by eating fish or other aquatic anima...ls. The worm typically emerges through the skin on a lower limb of the host 1 year after infection, causing pain and disability.

Le syndrome respiratoire aigu provoqué par le coronavirus-2 (SARS-CoV-2), initialement décrit en Chine, est responsable
de la pandémie que nous connaissons actuellement sous le nom de coronavirus disease 2019 ou COVID-19. L'épidémie de
coronavirus a été déclarée « urgence de santé publi...que mondiale » par l'Organisation mondiale de la santé (OMS) le 30 janvier 2020 . L'Afrique a été atteinte plus tard que les autres continents, mais à la date du 3 mai, tous les pays africains
avaient notifié au moins un cas. À la date du 09 juin 2020, l'Afrique comptait près de 200 000 cas confirmés, plus de
5000 décès, avec 25 pays ayant plus de 1000 cas actifs. Les patients atteints par ce virus peuvent développer des symptômes allant jusqu'à l'insuffisance respiratoire aiguë sévère

Leptospirosis, a spirochaetal zoonosis, occurs in diverse epidemiological settings and affects vulnerable populations, such as rural subsistence farmers and urban slum dwellers. Although leptospirosis is a life-threatening disease and recognized as an important cause of pulmonary haemorrhage syndrom...e, the lack of global estimates for morbidity and mortality has contributed to its neglected disease status

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 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.

Snakebite envenoming is a potentially life-threatening disease that typically results from the injection of a mixture of different toxins (“venom”) following the bite of a venomous snake. Envenoming can also be caused by venom being sprayed into a person’s eyes by certain species of snakes tha...t have the ability to spit venom as a defence measure. Not all snakebites result in envenoming: some snakes are non-venomous and venomous snakes do not always inject venom during a bite. About 50–55% of all snakebites result in envenoming. Snake venoms are complex mixtures of protein and peptide toxins, varying from one species to another, and even within species. The toxins in snake venoms are evolutionarily adapted to interact with a large variety of cellular targets in the organisms exposed to them. In humans and animals, snakebite envenoming affects multiple organ systems (depending on the particular species of snake and the classes of toxins present in the venom) and can cause, among other things: haemorrhage and prolonged disruption of haemostasis, neuromuscular paralysis, tissue necrosis, myolysis (muscle degeneration), cardiotoxicity, acute kidney injury, thrombosis and hypovolaemic shock.

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 devastating and societally important zoonotic disease, which is transmitted principally to humans through the bite of infected dogs. This acute, progressive viral encephalitis has the highest case fatality of any infectious disease and kills tens of thousands of people annually, with chi...ldren and impoverished communities being affected disproportionately.

Rabies has an enormous impact on both agriculture and conservation biology, but its greatest burden is undeniably on public health. As such, routine methods for rapid risk assessment after human exposures to rabies as well as applications for laboratory-based surveillance, production of biologicals ...and management of this infectious disease are critical. Given its mandate to improve human health and control disease among its Member States, WHO has led the production of this fifth edition of Laboratory techniques in rabies.

To understand the national situation, Ethiopia did a situation assessment, launched its first strategy in 2011, and took action to contain AMR, as detailed in the blue boxes found throughout this strategy. This updated version of the strategy was in response to the revised health and medicines polic...ies, health sector transformation plan, and the resolutions of the 68th World Health Assembly
of May 2015 and so that Ethiopia’s efforts could be coordinated with global initiatives in the prevention and containment of AMR.

The ICAT is a simple and practical approach for assessing the adequacy of existing infection prevention and control practices and provides specific recommendations for improving practices and monitoring their effectiveness over time
Nosocomial or health-facility-acquired infections are a serious issue, representing one of the most significant causes of morbidity and mortality in healthcare systems and consuming many scarce resources, especially in developing countries. Although much has been done, particularly in the hospital s...etting, to reduce the risk of these infections, the problem persists and demands innovative and cost-efficient solutions.
Although the care provided in most primary health care facilities is predominantly ambulatory with few or no inpatient beds, infection prevention is still important to minimize or eliminate the risks of facility-acquired infections and assure quality patient care.
Health facilities and hospitals should have written infection control procedures and guidelines in place and should also be monitoring that these procedures are adhered to in both inpatient and ambulatory care settings.
