The worldwide health system has been marked by the SARS-CoV-2 pandemic. French educational system has been upset, especially medical schools, which, because of their hospital location, are particularly exposed to the spread of the virus. The medical school of Paris-Saclay University, located within bicetre University Hospital, AP-HP, must therefore adapt on a daily basis to ensure educational continuity. Taking advantage of an exceptional scientific ecosystem, innovative viral epidemic propagation modeling approaches based on both simulation and contact tracing data will be tested in real-life conditions. These propagation models will serve to scientifically optimize future educational organization procedures in this medical school.
All the participants will be equipped with individual wireless contact tracing technology.
Anonymised contact events will be automatically monitored for a period of two months to
measure the daily contact flow density between the students at medical school. Epidemic
simulation models will be enriched with these real contact tracing data to generate optimized
viral propagation probability networks. During the same period, CO2 measurement will be
performed in several relevant sectors (classrooms, amphitheaters, corridors etc) to allow a
more holistic understanding of the propagation conditions. Finally, the probabilistic models
will be confronted to the results of a two step COVID-19 screening campaign.
Other: Antigenic tests (on saliva samples)
SARS-CoV-2 screening tests: two massive antigenic tests campaigns (on salivary samples).
Other: Individual electronic sensor port
Individual electronic sensor recording contacts but not their location (in the form of a bracelet, a key ring or a badge) Contact data collection points (5 maximum, located at compulsory passage points for participants). When a sensor is close to one of these terminals, it discharges its contacts in seconds.
Other: Atmospheric measurements of CO2
Atmospheric measurements of CO2 in the relevant closed places of the faculty (lectures / practical work / BU / refectory): battery operated sensors. When a sensor is installed in a place, the ventilation conditions (number of open windows, etc.) as well as the number of people present will be noted.
