La résistance aux antimicrobiens Esurvient lorsque les micro-organismes (bactéries, champignons, virus et parasites) évoluent quand ils sont exposés à des médicaments antimicrobiens (comme les antibiotiques, les antifongiques, les antiviraux, les antipaludiques et les anthelminthiques).
On ap...pelle parfois «super bactéries» celles qui développent une résistance aux antimicrobiens, mais cela concerne tous les micro-organismes.
En conséquence, les médicaments perdent leur efficacité et les infections persistent dans l’organisme, augmentant le risque de transmission à d’autres personnes.

Advice and guidance on the health needs of migrant patients for healthcare practitioners.
Chagas disease is increasingly reported in Latin American migrants who have settled in Europe. It has rarely been reported in the UK due to lack of testing and awareness.
Chagas disease (American trypanosomia...sis) is a zoonosis caused by the flagellate protozoan parasite Trypanosoma cruzi.

There are 3 main forms of leishmaniases: visceral (the most serious form because it is almost always fatal without treatment), cutaneous (the most common, usually causing skin ulcers), and mucocutaneous (affecting mouth, nose and throat).
Leishmaniasis is caused by protozoan parasites which are tra...nsmitted by the bite of infected female phlebotomine sandflies.
The disease affects some of the world’s poorest people and is associated with malnutrition, population displacement, poor housing, a weak immune system and lack of financial resources.
An estimated 700 000 to 1 million new cases occur annually.
Only a small fraction of those infected by parasites causing leishmaniasis will eventually develop the disease.

The World Health Organization's malaria fact sheet provides an overview of malaria, a life-threatening disease caused by Plasmodium parasites transmitted through the bites of infected female Anopheles mosquitoes. It highlights that malaria is preventable and curable, yet remains a significant glo...bal health challenge. Key statistics from 2023 indicate an estimated 263 million malaria cases and 597,000 deaths worldwide, with the WHO African Region bearing the majority of this burden. The fact sheet details transmission methods, symptoms, at-risk populations, diagnostic approaches, treatment options—including the use of artemisinin-based combination therapies (ACTs)—and preventive measures such as insecticide-treated nets (ITNs) and indoor residual spraying (IRS). It also discusses the impact of malaria on vulnerable groups like children under five and pregnant women, and outlines WHO's global response strategies aimed at reducing malaria incidence and mortality rates.

Le site web de l'OMS intitulé « Paludisme » offre un aperçu complet du paludisme, une maladie potentiellement mortelle causée par des parasites du genre Plasmodium et transmise principalement par des piqûres de moustiques dans les pays tropicaux. Il fournit des informations sur les symptômes,... les groupes à risque, les mesures de prévention et les options de traitement. Le site présente également des statistiques récentes : en 2023, on estime à 263 millions le nombre de cas de paludisme et à 597 000 le nombre de décès dans 83 pays, la région africaine étant la plus touchée avec 94 % des cas et 95 % des décès. Les enfants de moins de cinq ans représentaient environ 76 % des décès dans cette région.

All malaria-endemic countries in the Region of the Americas have taken on the challenge of eliminating malaria and have focused their health programs and strategies on that goal. The risk of emergence of artemisinin resistance in the Americas, the characteristics of P. falciparum parasite, and the e...pidemiological evidence of subnational territories experiencing reintroduction of P. falciparum urge for a call to push for P. falciparum elimination as an intermediate goal of the elimination of all malaria human species. Derived from the elimination of P. falciparum, other important results are expected, such as the empowerment of different actors and entities for the elimination of malaria inspired by the achievements of the elimination of P. falciparum, using early victories as a catalyst. This technical note provides guidance on actions to accelerate P. falciparum elimination in areas close to achieving this goal without compromising unified malaria elimination efforts (P. vivax - P. falciparum), while contributing to the country's ultimate goal of eliminating malaria overall. The acceleration of P. falciparum elimination has several goals: mitigating the risk that resistance to artemisinin and associated drugs will emerge and spread; accelerating the reduction in the total number of malaria cases in areas with a significant proportion of P. falciparum; accelerating malaria elimination (both P. vivax and P. falciparum), considering that P. falciparum is one of the triggers of P. vivax relapses; developing capacities in interventions to accelerate malaria elimination by building on the experience of P. falciparum elimination; and empowering different actors, including high-level authorities, donors, municipalities, and other entities involved in malaria elimination, by inspiring them with the achievements of P. falciparum elimination.

The NLM Malaria Screener is a mobile app developed by the U.S. National Library of Medicine to support the diagnosis of malaria through automated analysis of blood smear images. It uses smartphone microscopy and machine learning to detect malaria parasites in thin blood smears, helping health worker...s and lab technicians—especially in low-resource settings—screen for Plasmodium falciparum infections. The app is intended for research and educational purposes and aims to enhance diagnostic accuracy where access to expert microscopists is limited. It provides results quickly and can assist in training or field screening, but it is not approved for clinical use.

2nd edition. The purpose of this document is to present updated standardized protocols that P. falciparum-endemic countries can use to determine the prevalence of parasites with pfhrp2/3 gene deletions causing negative HRP2 RDT results among symptomatic falciparum patients. The findings should be us...ed to guide RDT selection; more specifically when to shift away from exclusive use of HRP2 to detect P. falciparum infections.

In areas of Mexico, Central America, and South America, where the Trypanosoma cruzi parasite is present in triatomine bugs, improved housing and spraying insecticide inside housing to eliminate the bugs has significantly decreased the spread of Chagas disease. Screening of blood donations for Chagas... is another important public health tool to help prevent spreading the disease through blood transfusions. Early detection and treatment of new cases, including mother-to-baby (congenital) cases, will also help reduce the burden of disease.

DNDi’s long-term goal for sleeping sickness, also known as human African trypanosomiasis (HAT), is to develop and register two new drugs that are effective against both Stage 1 and Stage 2 of the disease and both subspecies of the parasite, T.b. gambiense and T.b. rhodesiense. T.b. rhodesiense is ...an acute form of the disease, occurring primarily in Eastern and Southern Africa. Better treatments for T.b. rhodesiense sleeping sickness are urgently needed.

Elle représente une menace croissante pour la santé publique et aucun pays n’est épargné. Il est particulièrement alarmant de constater la propagation rapide, dans le monde entier, des bactéries multirésistantes provoquant des infections courantes qui ne sont pas sensibles aux traitements antibiotiques habituellement utilisés, ainsi que des infections en particulier hospitalières, résistantes aux traitements antibiotiques de dernier recours . Le problème se pose actuellement en termes de développement durable : il dépasse largement le cadre de la santé humaine et interpelle le monde entier

Schistosomiasis is a chronic parasitic infection caused by worms. It is most common in rural and impoverished populations. In the Americas, the parasite species is Schistosoma mansoni, which is associated with intestinal schistosomiasis. The main risk factor for infection is exposure through househo...ld, work, or recreational activities in fresh water contaminated with faeces from infected humans. In the Region, for transmission to occur, Biomphalaria snails, the intermediate hosts of the parasite, must also be present in contaminated water. Children and adolescents are the populations most at risk
