The rate at which the SARS-CoV-2 virus spreads may depend on the age of the people infected. A new SARS-CoV-2 variant, B.1.1.7, emerged in the south-east of England in October 2020 (3) and has subsequently spread to several countries including France. Recent reports estimate that this new variant is up to 70% more transmissible than the original virus and is responsible for an increase in the number of cases (4, 5) .
