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.

Most of the global burden of sepsis occurs in low- and middle-income countries (LMICs), but the prevalence and etiology of sepsis in LMICs are not well understood. In particular, the lack of laboratory infrastructure in many LMICs has historically precluded an assessment of the pathogens leading to ...sepsis. A recent systematic review found that data describing antimicrobial resistance were absent for 43% of countries in Africa, and only two countries have national antimicrobial resistance plans. In addition, small studies have identified indiscriminate antibiotic use both in and out of hospital settings in sub-Saharan Africa. The absence of microbiological data and lack of antibiotic stewardship complicate sepsis management and almost certainly worsens outcomes, particularly in low-resource systems. The purpose of this study was to examine the prevalence, etiology, and outcomes of sepsis among a cohort of critically ill patients in a referral hospital of Malawi, with a focus on the prevalence of culture-confirmed bacteremia and urinary tract infections.

The document focuses on household water treatment methods to ensure access to safe drinking water, particularly in areas with limited access to clean water sources. It highlights the importance of safe water, noting that contaminated water is a major cause of waterborne diseases such as diarrhea and... cholera. Treating water at the household level is emphasized as an effective way to reduce health risks.
The document outlines several treatment methods, including boiling, which kills most pathogens; chlorination, which disinfects water by adding chlorine; filtration, which removes dirt and certain microbes using simple or advanced filters; and solar disinfection (SODIS), which involves exposing water in clear plastic bottles to sunlight for several hours to kill microbes. Additionally, it stresses the importance of safe water storage, such as using clean and covered containers to prevent recontamination, and practicing good hygiene, including regular handwashing and maintaining cleanliness around water sources.
By promoting these methods, the document aims to raise awareness and provide practical solutions for improving water quality at the household level, thereby reducing the spread of diseases and enhancing public health.

The protozoan parasite Trypanosoma cruzi causes Chagas disease, an important public health problem throughout Latin America. Current therapeutic options are characterised by limited efficacy, long treatment regimens and frequent toxic side-effects. Advances in this area have been compromised by gaps... in our knowledge of disease pathogenesis, parasite biology and drug activity. Nevertheless, several factors have come together to create a more optimistic scenario. Drug-based research has become more systematic, with increased collaborations between the academic and commercial sectors, often within the framework of not-for-profit consortia. High-throughput screening of compound libraries is being widely applied, and new technical advances are helping to streamline the drug development pipeline. In addition, drug repurposing and optimisation of current treatment regimens, informed by laboratory research, are providing a basis for new clinical trials. Here, we will provide an overview of the current status of Chagas disease drug development, highlight those areas where progress can be expected, and describe how fundamental research is helping to underpin the process.

Antimicrobial resistance (AMR) is a global public health crisis that resulted in 1.14 million deaths in 2021. According to the Institute for Health Metrics and Evaluation estimates, 96 416 of these deaths occurred in the World Health Organization (WHO) Eastern Mediterranean Region. All 22 countr...ies/territories in the Eastern Mediterranean Region are enrolled in the global AMR
surveillance system, and 17 countries/territories reported data in 2024 (for the year 2023). The total number of isolates reported to the system increased sixfold between 2017 and 2022, but the proportion of blood isolates is relatively very low. Most of the data come from public sector laboratories or hospitals, although the private sector has increased its participation in some countries/territories recently. Three pathogens account for three quarters of all the reported pathogens – Escherichia coli
(26%), Klebsiella pneumoniae (23%), and Staphylococcus aureus (22%).

For thousands of years, humans have been using wildlife for commercial and subsistence purposes. Wildlife trade takes place at local, national and international levels, with different forms of wildlife, such as live animals, partly processed products and finished products. Wildlife is a vital source... of safe and nutritious food, clothing, medicine, and other products, in addition to having religious and cultural value. Wildlife trade also contributes to livelihoods, income generation and overall economic development.
However, wildlife trade can have detrimental effects on species conservation, depleting natural resources, impoverishing biodiversity and degrading ecosystems (Morton et al., 2021). Wildlife trade, whether legal or illegal, regulated or unregulated, can pose threats to animal health and welfare. It also presents opportunities for zoonotic pathogens to spill over between wildlife and domestic animals, and for diseases to emerge with serious consequences for public or animal health and profound economic impacts (IPBES, 2020; Swift et al., 2007; Smith et al., 2009; Gortazar et al., 2014; Stephen, 2021; Stephen et al., 2022; FAO, 2020). The risk of pathogen spillover and disease emergence is amplified with increased interaction between humans, wildlife and domestic animals. The risk of pathogen spillover has also been exacerbated by climate change, intensified agriculture and livestock production, deforestation, and other land-use changes. Wildlife trade is also a risk to ecosystem biodiversity via the introduction of invasive species (Wikramanayake et al., 2021). Therefore, increased effort must be put into understanding the potential consequences of the wildlife trade, mapping and analysing the adjacent risks, and implementing strategies to manage those risks. Reducing wildlife-trade risks not only helps to limit disease but also minimises the negative effects of invasive species. Between 1960 and 2021, invasive alien species caused estimated cumulative damage of around 116 billion euros across 39 countries in the European Union alone, despite strict import regulations (Haubrock et al., 2021). The effect of invasive species is extremely apparent.

The Africa Centres for Disease Control and Prevention (Africa CDC) Biosafety and Biosecurity Initiative was launched by the Africa CDC in April 2019 with the aim of strengthening the African Union (AU) Member States’ biosafety and biosecurity systems and enabling them to comply with national and i...nternational requirements for biosafety and biosecurity including the International Health Regulations (IHR) (2005), the Biological Weapons Convention (BWC), and United Nations Security Council Resolution (UNSCR) 1540 and the multi-country Global Health Security Agenda (GHSA). The World Health Organization (WHO) Joint External Evaluation (JEE) and the Global Health Security Index report confirmed the known capacity gaps in biosafety and biosecurity among Africa Union Member (AU).
The regional consultations by Africa CDC conducted between 2019-2021 highlighted the deficiency or limited availability of standardized and regionally recognized training programs in the continent, limiting biosafety and biosecurity capacity building efforts in the region. In response, Africa CDC working with AU Member States developed a home grown, implementable and accessible professional training and certification program that is both recognized and endorsed by AU Member States. The Regional Training and Certification Program for Biosafety and Biosecurity Professionals, for African Biosafety and Biosecurity Professionals (RTCP-BBP) has four (4) areas of specialization, namely
Selection, Installation, Maintenance and Certification of Biological Safety Cabinets
Biorisk Management
Design and Maintenance of Facilities Handling High Risk Pathogens (Biocontainment Engineering)

As a high-burden neglected tropical disease, soil-transmitted helminth (STH) infections remain a major problem in the world, especially among children under five years of age. Since young children are at high risk of being infected, STH infection can have a long-term negative impact on their life, i...ncluding impaired growth and development. Stunting, a form of malnutrition in young children, has been long assumed as one of the risk factors in acquiring the STH infections. However, the studies on STH infection in children under five with stunting have been lacking, resulting in poor identification of the risk. Accordingly, we collected and reviewed existing related research articles to provide an overview of STH infection in a susceptible population of stunted children under five years of age in terms of prevalence and risk factors. There were 17 studies included in this review related to infection with Ascaris lumbricoides, Trichuris trichiura, hookworm, and Strongyloides stercoralis from various countries. The prevalence of STH infection in stunted children ranged from 12.5% to 56.5%. Increased inflammatory markers and intestinal microbiota dysbiosis might have increased the intensity of STH infection in stunted children that caused impairment in the immune system. While the age from 2 to 5 years along with poor hygiene and sanitation has shown to be the most common risk factors of STH infections in stunted children; currently there are no studies that show direct results of stunting as a risk factor for STH infection. While stunting itself may affect the pathogenesis of STH infection, further research on stunting as a risk factor for STH infection is encouraged.

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.
