Techniques are provided for implementing automated contagion detection and remediation (ACDR) features to detect and remediate environmental contagion conditions. For example, ACDR techniques can be used to target contagion contamination on surfaces in a trafficked area, rather than focusing detecting and remediating human symptoms. ACDR systems can include swarms of specially configured drones under control of one or more centralized controllers to detect presence of one or more types of pathogens on surfaces and to classify detected contagion events. In some embodiments, upon such detection, the same or other specially configured drones can be triggered to remediate the detected condition by removing the pathogen by disinfecting surfaces, by cordoning off infected areas, and/or in other ways. Some embodiments can further log and aggregate data relating to detected contagion events to support tracking, remediation, enforcement, protocol updating, research, and/or other efforts.
