However, in this period following the Covid-19 pandemic, it may be useful to recap such a current topic. In the public debate, it has often been heard that the Covid-19 was destined to evolve into a less virulent form, because it would be in the virus's interest to coexist with the human population. This concept can be defined as the \"Myth of the good pathogen\" and originated from Smith's \"law of declining virulence\". The successes achieved thanks to vaccinations and antibiotics led the medical community, between the 1940s and 1970s, to argue that the battle against infectious diseases had been won. However, the AIDS pandemic brought back down to earth the scientific community in their speculations about plagues. Since 1970s, biologists have advanced the \"virulence transmission trade-offs theory\", a new model according to which intermediate virulence maximizes pathogenicity as a result of a trade-off between virulence and transmission. The introduction of trade-off models represented a crucial change that replaced the binary logic according to which natural selection shaped adaptations, while maladaptation escaped selection. This change was fundamental for the introduction of a new perspective in medicine, namely Evolutionary Medicine, which might be an essential tool not only for understanding the dynamics of epidemics, but also for preventing and curing infectious diseases.</p>","PeriodicalId":14006,"journal":{"name":"International Journal of Infectious Diseases","volume":" ","pages":"107836"},"PeriodicalIF":4.8,"publicationDate":"2025-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143374101","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This review critically assesses the current applications, limitations, and potential of RPA for detecting a broad spectrum of NTD pathogens, including viruses, bacteria, helminths, and fungi. The ability of RPA to operate under constant temperature conditions without the need for complex thermal cycling facilitates rapid pathogen detection within minutes, enhancing its utility for decentralized point-of-care testing in remote and underserved regions. RPA, however, faces limitations, including the labor-intensive and costly validation of primer design, especially for multiplex assays, and a susceptibility to non-specific amplification. These challenges highlight the need for continuous refinement to ensure reliable and consistent performance across diverse environmental conditions. Despite these constraints, the scalability of RPA assays and their compatibility with portable detection platforms make them well-suited for deployment in field settings without access to traditional laboratory infrastructure. This review emphasizes the transformative potential of RPA in NTD diagnostics, enhancing accessibility, precision, and timeliness of interventions, ultimately contributing to improved global public health outcomes.</p>","PeriodicalId":14006,"journal":{"name":"International Journal of Infectious Diseases","volume":" ","pages":"107831"},"PeriodicalIF":4.8,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143122762","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
