A method to and for a vehicle-based, mobile acquisition process of health data by sampling or testing of natural persons in pandemic situations which spread territorially, wherein a transmitting of a request notification to a fleet management centre and an evaluating and locating of the request takes place through the fleet management centre, characterized in that it is established from which territory the request notification comes, whether risk considerations already exist regarding this territory, whether mobile units are already situated in the vicinity of the territory and whether it is possible to reach the corresponding territory with the mobile unit, i.e. a vehicle, in an estimable time, subsequent checking of the readiness and of the location of mobile units for commissioning a sampling and testing, selecting one of the mobile units and placing a travel order to the selected unit and delivering a route specification to the mobile unit, monitoring the route of the respective mobile unit through the fleet management centre and transmitting information to the respective natural person together with notification of an expected arrival time, to avoid waiting times and unnecessary contacts with further persons, parallel monitoring of possible further received request notifications and drawing up a lead time plan for the fleet management by adapting the travel route for optimization of the use of the vehicles, shortening of the travel time and rapid contact with the persons who are to be tested, determining a pick-up location for the brief, sample-relevant admission of the respective natural person into the mobile unit, carrying out the sampling and/or the necessary tests and recording and checking person-relevant data together with transferring these data into a central register or the cloud, evaluation of the sampling or of the test already in the mobile unit during travel in accordance with route specification, forwarding the sampling- or test results into the central register or the cloud, adapting the route specification by means of current specifications through the fleet management centre, running through further cycles of samplings and/or tests in the course of the operating time of the mobile unit by setting off in accordance with route specification and calling at the pick-up locations and technical and hygiene support for the mobile unit for restoring readiness for re-use for a next usage cycle by means of cleaning and disinfection. it is established from which territory the request notification comes, whether risk considerations already exist regarding this territory, whether mobile units are already situated in the vicinity of the territory and whether it is possible to reach the corresponding territory with the mobile unit, i.e. a vehicle, in an estimable time, subsequent checking of the readiness and of the location of mobile units for commissioning a sampling and testing, selecting one of the mobile units and placing a travel order to the selected unit and delivering a route specification to the mobile unit, monitoring the route of the respective mobile unit through the fleet management centre and transmitting information to the respective natural person together with notification of an expected arrival time, to avoid waiting times and unnecessary contacts with further persons, parallel monitoring of possible further received request notifications and drawing up a lead time plan for the fleet management by adapting the travel route for optimization of the use of the vehicles, shortening of the travel time and rapid contact with the persons who are to be tested, determining a pick-up location for the brief, sample-relevant admission of the respective natural person into the mobile unit, carrying out the sampling and/or the necessary tests and recording and checking person-relevant data together with transferring these data into a central register or the cloud, evaluation of the sampling or of the test already in the mobile unit during travel in accordance with route specification, forwarding the sampling- or test results into the central register or the cloud, adapting the route specification by means of current specifications through the fleet management centre, running through further cycles of samplings and/or tests in the course of the operating time of the mobile unit by setting off in accordance with route specification and calling at the pick-up locations and technical and hygiene support for the mobile unit for restoring readiness for re-use for a next usage cycle by means of cleaning and disinfection.
