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.

Tsetse Control and Gambian Sleeping Sickness; Implications for Control Strategy
Tirados, I.; Esterhuizen, J.; Kovacic, V.; Mangwiro, TNC.; Vale, GA et al.
PLOS Neglected Tropical Diseases
(2015)
CC
Sleeping sickness is controlled by case detection and treatment but this often only reaches less than 75% of the population. Vector control is capable of completely interrupting HAT transmission but is not used because of expense. We conducted a full scale field trial of a refined vector control tec
...
hnology. From preliminary trials we determined the number of insecticidal tiny targets required to control tsetse populations by more than 90%. We then carried out a full scale, 500 km2 field trial covering two HAT foci in Northern Uganda (overall target density 5.7/km2). In 12 months tsetse populations declined by more than 90%. A mathematical model suggested that a 72% reduction in tsetse population is required to stop transmission in those settings. The Ugandan census suggests population density in the HAT foci is approximately 500 per km2. The estimated cost for a single round of active case detection (excluding treatment), covering 80% of the population, is US$433,333 (WHO figures). One year of vector control organised within country, which can completely stop HAT transmission, would cost US$42,700. The case for adding this new method of vector control to case detection and treatment is strong. We outline how such a component could be organised.

wirkungen für Wohlergehen und Sicherheit der Gesellschaften. Dieser Bericht bietet eine Übersicht der vielfältigen Einwirkung der natürlichen Umwelt auf die menschliche Gesundheit. Er legt dar, wie Natur und Ökosysteme Gesundheit und Wohlbefinden unterstützen und schützen können und wie zugleich die Zerstörung der Natur und der Verlust an Biodiversität die menschliche Gesundheit bedrohen. Er ist an ein Publikum gerichtet, das nicht über umfassende Erfahrung mit den Verbindungen zwischen Natur und Gesundheit verfügt. Diese Übersicht richtet sich in erster Linie an Personen, die sich beruflich oder politisch mit Umwelt und Gesundheit beschäftigen, kann aber auch für andere Bereiche relevant sein, die mit dem Schutz, der Handhabung und der Nutzung von Natur und Biodiversität befasst sind.

sibilidades de sobrevida, disfrutar de una vida plena y, sobre todo, alcanzar la mejor calidad de vida posible y morir sin sufrimiento. Está dirigido a los profesionales de la salud que se dedican al tratamiento de pacientes oncológicos pediátricos y que, directa o indirectamente, deben enfrentarse con las complicaciones que pueda causar el tratamiento a todos los niveles. Su contenido puede contribuir a la realización de un diagnóstico más certero de las alteraciones de la cavidad oral, así como al desarrollo de estrategias para la prevención y el tratamiento de estas manifestaciones. No se establecen orientaciones directas para responsables parentales ni cuidadores, pero sí se presenta información que sirve como guía para el cuidado bucal, de acuerdo con la estructura y la composición de los equipos de los distintos centros de tratamiento contra el cáncer.

The Onchocerciasis Control Programme in West Africa (OCP) undertook regional and large scale frght against onchocerciasis in West Africa in 1974 using a vector control strategy. By 2002 OCP had succeeded in eliminating the disease as a public health, socio-economic and development problem in 10 out

of I I countries. This campaign was highly technical and expensive. ln 1987, Merck & Co.,lnc. committed themselves to provide ivermectin free of charge for as long as needed to onchocerciasis endemic countries. This made it possible to envrsage the extension of onchocerciasis control activities to the remaining endemic countries in Africa.

Social Appropriation of Knowledge and its contributions to the prevention of cutaneous leishmaniasis in rural contexts
Paipilla, K., Castro-Arroyave, D., Grajales,L. et al.
BMJ Innovations :234–239. doi:10.1136bmj
(2022)

Cutaneous leishmaniasis (CL) is a neglected infectious endemic disease that is transmitted through the bite of a vector insect (sandfly) of the Lutzomyia genus,typical of rural geographical territories, and causes disfiguring skin ulcers and disabilities. It is estimated that CL affects between 600
...
000 and 1 000 000 people a year around the world, mainly in the America s, the Mediterranean basin, the Middle East and Central Asia. Eighteen of the 21 countries that make up the Latin American (LA) region are considered endemic areas for this neglected tropical disease. Colombia is one of the countries that reports the majority of global cases with 6161 in 2020 and has the second highest number of cases in the Americas, after Brazil.

Onchocerciasis used to be an important public health problem in Africa, with over 37 million people infected and millions suffering from debilitating skin disease, terrible itching, impaired vision and
blindness. But the epidemiological situation has improved dramatically over the last two decades.

Community directed treatment with ivermectin has effectively brought the disease under control in most endemic areas where onchocerciasis is no longer a public health risk.

Leptospirosis is a bacterial zoonotic disease of worldwide importance, though relatively neglected in many African countries including sub Saharan Africa that is among areas with high burden of this disease. The disease is often mistaken for other febrile illnesses such as dengue, malaria, rickettsi

oses and enteric fever. Leptospirosis is an occupational disease likely to affect people working in environments prone to infestation with rodents which are the primary reservoir hosts of this disease. Some of the populations at risk include: sugarcane plantation workers, wetland farmers, fishermen and abattoir workers. In this study we investigated the prevalence of antibodies against Leptospira among sugarcane plantation and factory workers, fishing communities as well as among rodents and shrews in domestic and peridomestic environments within the study areas.

Nearly 260 000 people died in parts of Somalia between October 2010 and April 2012, including
133 000 children under five during the famine and food crisis in Somalia making it the worst famine in history.

As of 12 December 2022, over 645 million people worldwide have been diagnosed with COVID-19, with over 6.6 million deaths (4).

ies (4). Vaccination has substantially reduced case numbers and hospitalizations in many countries,but limitations in global access to vaccines mean that many populations, including those in low- and middle-income countries, remain vulnerable. Even in vaccinated individuals, uncertainties remain about duration of protection and efficacy, and the degree of crossprotection with new variants.
There remains a need for more effective treatment and management for those affected by COVID-19. The pandemic – and the
explosion of both research and misinformation – has highlighted the need for trustworthy, accessible and regularly updated living
guidelines to place emerging findings into context and provide clear recommendations for clinical practice

placing Delta worldwide – was considered Omicron has a substantial growth advantage, higher secondary attack rates and a higher observed reproduction number than Delta.
There is now significant evidence that immune evasion contributes to the rapid spread of Omicron. Other factors may be a shorter
serial interval (by about 0.8 to 1.2 days compared to Delta) and potential increased intrinsic transmission fitness . There is
growing evidence that with Omicron, there is lower vaccine effectiveness (VE) against infection and symptomatic disease soon after vaccination compared to Delta. There is also evidence of accelerated waning of VE over time of the primary series against infection and symptomatic disease for the studied vaccines. Further studies are required to better understand the drivers of transmission and declining incidence in various settings. These factors include the intrinsic transmission fitness properties of the virus, degree of immune evasion, vaccination coverage and level of vaccine-derived and post-infection immunity, levels of social mixing and degree of application of public health and social measures (PHSM).
