Abstract:
In order to contribute to the prevention of the spread of Covid-19, the operational hygiene team of a Parisian geriatric hospital set up weekly iterative screening by saliva test among professionals. Collaboration with the Covisan system enabled epidemiological monitoring and highlighted a link between clusters and the contamination of carers who were then able to be evicted early thanks to the screening. The results, which are shared in this feedback document, show the support of the hospital staff and the interest of screening.
