• Departmental incidence rates: increased incidence rates in all departments. The highest rates are observed in Moselle and Marne (567 cases per 100,000 inhabitants in both departments), and the lowest is observed in Vosges (348 cases per 100,000 inhabitants).

• Variants: The screening rate is 41%, and 98% of screened tests indicate a suspected Omicron variant (for tests where the mutation is sought and interpretable). In week 25 of 2022, 72% of screened samples carried a mutation consistent with the new Omicron sublineages, including BA.2.12.1, BA.4, and BA.5 (compared to 59% in week 23 of 2022).
