In S09, SARS-CoV-2 viral circulation is tending to stabilize at a high level, with the rate of decline slowing. The island of Réunion remains the department with the highest incidence and hospitalization rates in France.

The Omicron variant accounted for 100% of interpretable sequences since Week 06, with a marked increase in BA.2 since Week 06, representing the majority (59%) of Omicron sublineages in Week 08.

The number of weekly deaths recorded in Réunion was declining in S-09.

An uptick in the circulation of respiratory syncytial virus is observed among children under 2 years of age. In this fragile context of lifting restrictions, it is essential to remain vigilant and mobilized against COVID-19.
