Abstract: Disclosed herein is a device for managing a spread of infectious diseases among users. Further, the device comprises a communication device, a location sensor, a pathogen tracer microcontroller device, an output device, and a storage device. Further, the communication device receives device data from devices. Further, the location sensor generates location data based on a location of the device corresponding to a time period. Further, the pathogen tracer microcontroller device analyzes the device data and the location data, determines a spatiotemporal proximity of the device to the devices, compare the spatiotemporal proximity with a predetermined spatiotemporal proximity, determines a risk of the spread of a pathogen causing an infectious disease between the users, and generates an alert. Further, the output device produces alert signals based on the alert. Further, the storage device stores the alert and a status of a user corresponding to the infectious disease.
