The mosquito borne infections testing ecosystem spans upstream reagent and component suppliers, midstream manufacturers and system integrators, and downstream diagnostic and public‑health customers. Upstream participants provide raw chemicals, antibodies, and nucleic‑acid extraction kits that form the analytical core of assays. Midstream actors—including instrument OEMs, technology developers, and integration firms—convert these inputs into calibrated platforms and multiplex software solutions. Downstream, national health agencies, hospital laboratories, and research institutes apply the finished systems to detect arboviruses such as dengue, Zika, and West Nile. Value is created when assay sensitivity and throughput meet regulatory thresholds, and captured through procurement contracts, service agreements, and data‑reporting mandates.
