Abstract

Given the growing threat posed by viral hemorrhagic fevers, the development of surveillance tools is crucial to provide accurate and rapid solutions. Public health response involves risk assessment as well as effective and sustainable surveillance to ensure downstream communication and preparedness. A serological approach that offers high precision and throughput, cost efficiency, and multiplexing capacity is critical. In this work, we evaluated a Luminex-based multiplex microsphere immunoassay for five hemorrhagic fever viruses (HFVs) among the World Health Organization (WHO) blueprint. This five-plex MagPix immunoassay confirmed the presence of Rift Valley fever and Crimean–Congo hemorrhagic fever, but also revealed the exposure of human populations to hantaviruses in Senegal, underscoring the importance of regular serosurveillance in the identification of HFV hotspots.

鉴于病毒性出血热造成的威胁日益严重，开发监测工具对于提供准确、快速的解决方案至关重要。公共卫生应对措施包括风险评估以及有效和可持续的监测，以确保下游的沟通和准备工作。一种具有高精度、高通量、高成本效益和复用能力的血清学方法至关重要。在这项工作中，我们对基于 Luminex 的多重微球免疫测定进行了评估，以检测世界卫生组织（WHO）蓝图中的五种出血热病毒（HFV）。这种五重 MagPix 免疫测定证实了裂谷热和克里米亚-刚果出血热的存在，同时也揭示了塞内加尔人类暴露于汉坦病毒的情况，强调了定期血清监测对确定 HFV 热点的重要性。

期刊介绍： Transboundary and Emerging Diseases brings together in one place the latest research on infectious diseases considered to hold the greatest economic threat to animals and humans worldwide. The journal provides a venue for global research on their diagnosis, prevention and management, and for papers on public health, pathogenesis, epidemiology, statistical modeling, diagnostics, biosecurity issues, genomics, vaccine development and rapid communication of new outbreaks. Papers should include timely research approaches using state-of-the-art technologies. The editors encourage papers adopting a science-based approach on socio-economic and environmental factors influencing the management of the bio-security threat posed by these diseases, including risk analysis and disease spread modeling. Preference will be given to communications focusing on novel science-based approaches to controlling transboundary and emerging diseases. The following topics are generally considered out-of-scope, but decisions are made on a case-by-case basis (for example, studies on cryptic wildlife populations, and those on potential species extinctions): Pathogen discovery: a common pathogen newly recognised in a specific country, or a new pathogen or genetic sequence for which there is little context about — or insights regarding — its emergence or spread. Prevalence estimation surveys and risk factor studies based on survey (rather than longitudinal) methodology, except when such studies are unique. Surveys of knowledge, attitudes and practices are within scope. Diagnostic test development if not accompanied by robust sensitivity and specificity estimation from field studies. Studies focused only on laboratory methods in which relevance to disease emergence and spread is not obvious or can not be inferred (“pure research” type studies). Narrative literature reviews which do not generate new knowledge. Systematic and scoping reviews, and meta-analyses are within scope.
