Provided is a process, including: obtaining leaders of an organization and participants of the organization; obtaining a set of facilities of the organization; obtaining geolocation-pathogen-risk scores of the facilities; obtaining a current, first state of a finite state machine, the finite state machine having four or more states, each of the four or more states corresponding to a level of at least some of the geolocation-pathogen-risk scores or a first derivative with respect to time of at least some of the geolocation-pathogen-risk scores; determining to transition to a second state of the finite state machine based on the geolocation-pathogen-risk scores; executing logic of the second state configured to cause a user interface to be presented on computing devices of at least some of the leaders of the organization, the user interface including proposed natural language text messages to at least some of the participants of the organization.
