Brief summary
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.
Detailed description
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.
Interventions
OTHERAntigenic tests (on saliva samples)
SARS-CoV-2 screening tests: two massive antigenic tests campaigns (on salivary samples).
OTHERIndividual 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.
OTHERAtmospheric 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.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Simulations results compared with the COVID-19 two-step screening campaign results | 2 months | Develop and validate a simulation tool for the spread of an epidemic in a university-type environment, updated by the effective measurement of contacts between individuals (wireless digital search of contacts). |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| CO2 atmospheric measurement | 2 months | The CO2 rate will be measured under very diverse conditions in terms of room size, number of people, type of ventilation. These systematic measurements together with the reading of precise conditions will allow us to establish a precise correspondence between the various factors and this rate. This should improve our understanding of the chains of contamination. and the circumstances that may have favored the spread of the disease. |
