A sanitization system for a space includes an ultraviolet (UV) light source configured to emit UV light. The system includes a sensor device configured to sense positions of a plurality of individuals within the space. The system includes a controller in communication with the sensor device. The controller is configured to monitor the positions of the plurality of individuals, determine, based on the positions of the plurality of individuals, that two or more individuals are less than a threshold distance from each other, and in response to determining that the two or more individuals are less than a threshold distance from each other, control the UV light source to emit UV light towards a proximate region between the two or more individuals.
