1. A droplet infection suppression system comprising:
an airflow generator configured to generate an airflow for separating a space into a plurality of regions;
first detectors corresponding one-to-one to the plurality of regions;
a second detector; and
a controller which, when the second detector detects coughing or sneezing and the first detectors detect human presence in a first region of the plurality of regions, human presence in a second region of the plurality of regions, and no human presence in a third region of the plurality of regions, causes the airflow generator to generate an airflow, wherein
the first region, the second region, and the third region are provided side by side and have no common region,
the third region is provided between the first region and the second region,
one or more additional regions of the plurality of regions are not provided between the first region and the second region,
the airflow separates the first region and the second region, and
the airflow does not separate the first region and the third region.
