1. A system for detecting symptoms of occupant illness, the system comprising:
user interface;
a storage configured to maintain a visualization application and radar data from a radar source; and
a processor in communication with the storage and the user interface, and programmed to:
receive a background image from a camera of an area that occupants are occupying,
receive the radar data from the radar source,
execute a human-detection model configured to detect the occupants based on the radar data,
execute an activity-recognition model or vital-signs-recognition model configured to recognize radar-based symptoms of illness in the detected occupants based on the radar data,
determine a location of the radar-based recognized symptoms of illness utilizing the radar data from the radar source, and
execute the visualization application to display, in the user interface, an overlaid image overlaid onto the background image, the overlaid image including, for each determined location of symptoms, an indicator that the radar-based recognized symptoms of illness occurred at that location, wherein the overlaid image includes a color-coded heat map that varies in intensity corresponding to a number of recognized symptoms of illness at that location.
