• The adjusted regional crude incidence rate rose to 472 cases per 100,000 inhabitants.

• The same upward trend was observed overall for the testing rate.

• The positivity rate (19.5%) increased at the regional level and across all Île-de-France departments for the third consecutive week.

• The BA.2 sublineage of the Omicron variant remains predominant in Île-de-France, but there are steady increases in the share of the BA.4 and BA.5 sublineages.

• Use of primary care services (SOS Médecins & Oscour) for “suspected COVID-19” increased slightly.

• The number of new hospitalizations and the number of new admissions to intensive care units increased. The number of COVID-19-related deaths in hospitals decreased. (SI-VIC data).

• New reports of COVID-19 cases by long-term care facilities remained stable, but the number of cases among residents was increasing.
