Screening around a COVID-19 cluster: Exploring its impact on a local virus outbreak.

Objective: In March 2020, we implemented screening of the contacts of a COVID-19 cluster having occurred in the Lot-et-Garonne department, the first department of the Nouvelle-Aquitaine region to be affected by the active circulation of SARS-CoV-2. We aimed to describe the impact of this screening on the local SARS-CoV-2 outbreak.

Methods: All high-risk contacts, as well as the individuals living in their households, were screened.
