Abstract: An infection risk map provision system includes virus sensors for detecting viruses in the air, the virus sensors being provided at different positions, a communication unit that collects detection information obtained by the virus sensors, and a control unit that provides, on the basis of the detection information, an infection risk map representing the distribution of infection risk information. The control unit sets display granularity for the infection risk information on the infection risk map displayed on an information terminal on the basis of granularity information corresponding to the virus sensors and creates the infection risk map by superimposing the infection risk information upon a map on the basis of the set display granularity and positional information.

Abstract: A detection device comprises a cyclone-type collection part for collecting particles contained in a gas into a collection liquid with a swirling airflow, a detection part for detecting the particles collected by the cyclone-type collection part; and a cleaning part for cleaning the cyclone-type collection part with a cleaning liquid. The cleaning part cleans the cyclone-type collection part by swirling the cleaning liquid with the swirling airflow generated in the cyclone-type collection part.
