La résistance aux antimicrobiens (ou RAM, cette abréviation étant est ici également employée en mode adjectif pour désigner les organismes « résistants aux antimicrobiens ») est une préoccupation majeure pour la santé publique mondiale et une question de sécurité san...itaire des aliments. Lorsque des pathogènes deviennent résistants aux agents antimicrobiens, ils peuvent présenter un risque plus important pour la santé découlant d’un éventuel échec thérapeutique, de la diminution de choix thérapeutiques et de la probabilité accrue d’apparition et de gravité de la maladie. Les problèmes en rapport avec la RAM sont liés de façon inhérente à l’usage des antimicrobiens dans tous les types d’environnements, y compris les utilisations humaines et non humaines. L'utilisation d’agents antimicrobiens dans la production alimentaire animale et végétale représente un facteur de risque important pour la sélection et la transmission de micro-organismes résistants aux antimicrobiens (micro-organismes RAM) et de déterminants de la résistance aux antimicrobiens (déterminants de la RAM) des animaux et des plantes alimentaires à l’humain par sa consommation d’aliments.

Antimicrobial resistance is one of the most important threats to the health worldwide. Antimicrobial resistance or drug resistance is the reduction of the pharmaceutical effects of a drug against a disease or reduction of its effectiveness in improving the clinical signs of a disease. Antimicrobial ...resistance occurs naturally but misuse of antibiotics in human and animals significantly accelerates the process of developing antimicrobial resistance. In fact, antimicrobial resistance refers to the resistance of a microorganism to one or more antimicrobial drugs which had been previously sensitive to these drugs. Antimicrobial resistance can occur in a wide variety of pathogens including bacteria, parasites, viruses, fungi, and cancer cells and may threaten the life of every person, in every age, and in every country

WHO and Psyon Games have joined forces to launch a new tower defense game called the Antidote COVID-19 to turn complex, scientific information into a fun learning experience. During the course of the game, players will learn about their immune system, pathogens, vaccines and how to protect themselve...s from COVID-19.
The game comes at a critical point of the pandemic where misinformation is hindering COVID-19 vaccine acceptance and adherence to other public health measures due to fear, mistrust and doubt. By putting players in the driver’s seat, the game urges everyone to play a role in fighting harmful misinformation online, and learning and sharing the facts from trusted sources of information.
The game starts just before the pandemic begins. The player is recruited to halt the spread of SARS-COV-2, the virus that causes COVID-19, by developing vaccines and helping the human immune system fight off the virus. Based on real events, this online adventure takes the player to the frontline of science, ultimately providing lifesaving information in the palms of their hands.

Climate change refers to long-term shifts in weather conditions and patterns of extreme weather events. It may lead to changes in health threat to human beings, multiplying existing health problems. This review examines the scientific e...vidences on the impact of climate change on human infectious diseases. It identifies research progress and gaps on how human society may respond to, adapt to, and prepare for the related changes. Based on a survey of related publications between 1990 and 2015, the terms used for literature selection reflect three aspects — the components of infectious diseases, climate variables, and selected infectious diseases. Humans' vulnerability to the potential health impacts by climate change is evident in literature. As an active agent, human beings may control the related health effects that may be effectively controlled through adopting proactive measures, including better understanding of the climate change patterns and of the compound disease-specific health effects, and effective allocation of technologies and resources to promote healthy lifestyles and public awareness. The following adaptation measures are recommended: 1) to go beyond empirical observations of the association between climate change and infectious diseases and develop more scientific explanations, 2) to improve the prediction of spatial–temporal process of climate change and the associated shifts in infectious diseases at various spatial and temporal scales, and 3) to establish locally effective early warning systems for the health effects of predicated climate change.

Chikungunya virus (CHIKV) is currently one of the most relevant arboviruses to public health. It is a member of the Togaviridae family and alphavirus genus and causes an arthritogenic disease known as chikungunya fever (CHIKF). It is characterized by a multifaceted disease, which is distinguished fr...om other arbovirus infections by the intense and debilitating arthralgia that can last for months or years in some individuals. Despite the great social and economic burden caused by CHIKV infection, there is no vaccine or specific antiviral drugs currently available. Recent outbreaks have shown a change in the severity profile of the disease in which atypical and severe manifestation lead to hundreds of deaths, reinforcing the necessity to understand the replication and pathogenesis processes. CHIKF is a complex disease resultant from the infection of a plethora of cell types. Although there are several in vivo models for studying CHIKV infection, none of them reproduces integrally the disease signature observed in humans, which is a challenge for vaccine and drug development. Therefore, understanding the potentials and limitations of the state-of-the-art experimental models is imperative to advance in the field. In this context, the present review outlines the present knowledge on CHIKV epidemiology, replication, pathogenesis, and immunity and also brings a critical perspective on the current in vitro and in vivo state-of-the-art experimental models of CHIKF.

This perspective draws on the record of ancient pathogengenomes and microbiomes illuminating patterns of infectious disease over the course of the Holocene in order toaddress the following question. How did major changes inliving circumstances involving the transition to and intensification of farmi...ng alter pathogens and their distributions? Answers to this question via ancient DNA researchprovide a rapidly expanding picture of pathogen evolution and in concert with archaeological and historical data, give a temporal and behavioral context for heath in the past that is relevant for challenges facing the world today, including the rise of novel pathogens.

American cutaneous leishmaniasis (CL) is a severely understudied and neglected“disease of poverty” widespread throughout Peru. Transmission dynamics of CL are complex, requiring sandfly vectors and mammalian reservoir hosts to maintain the pathogen in a local environment whereby incidental hosts... (people) can become infected. We employed a One-Health approach to understand CL transmission in rapidly changing region of northern Peru. We describe the characteristics of 529 CL positive patients from four participating clinics. Using conditional logistic regression, we assessed risk factors of CL for residents of small urban areas through a matched case-control study with 63 patients who had visited one of the same clinics for CL (cases) or other medical reasons (controls). We later enrolled 343 households as part of a community based study occurring in 15 urban and rural areas of Soritor. We
found 256 positive humans (n= 914) as tested via the Montenegro Skin Test; we found 11 positive dogs (n = 236) via an immunofluorescence antibody test. Our results suggest that most- if not all- of CL transmission is occurring in rural areas and that urban women and urban children engage in many high risk activities typically attributed to men. We find evidence that prevalence of past infection is highest among rural residents and men. We believe dogs are unlikely Leishmania reservoirs in either rural or urban settings. It remains unknown if the high number of MST positive children in rural areas is a result of peridomestic or intradomestic transmission.

The incubation period (the time the virus spreads from the peripheral nerves near the site of the bite via the spinal cord to the brain – see transmission and pathogenesis) ranges in general between 2 and 3 month (2 weeks to 6 years are reported) depending on the site of infliction, the amount of ...virus and the virus strain. Due to its neurotropism all known lyssaviruses cause severe neurological symptoms as a result of an acute encephalitis. Therefore, clinical signs in humans and animals are very similar.

Battling neglected tropical diseases (NTDs) is not easy for a number of reasons. The microbial world is mobile and the targets keep changing. This book reflects on a 15-year battle--one that is still continuing--against five tropical diseases that have been long neglected yet take a heavy toll in de...ath and human suffering today. It introduces some of the protagonists involved--patients in remote villages, health workers, community leaders, district and health ministry officials, researchers, donors and agency staff under the leadership of the World Health Organization (WHO). Its goal is to situate NTDs historically, culturally, and scientifically, and to illustrate the efforts taken over the years to end suffering and bring hope to the thousands of people who have been afflicted by these deadly diseases. Helping the WHO in this endeavour goes beyond fighting pathogens. It involves vigilance over a dangerous world and dedication to public health and well-being in a number of respects--from supporting human rights to creating a better environment for all.
