Key Points

In week 20 in Île-de-France, the decline in virological and hospital indicators continued, confirming the decrease in SARS-CoV-2 circulation. However, circulation remained at high levels, calling for continued vigilance.

• The crude incidence rate stood at 202 cases per 100,000 inhabitants and declined for the seventh consecutive week.

• The same downward trend was observed overall for the positivity rate (10.4%) at the regional level and across all departments in the Île-de-France region.

• The BA.2 sublineage of the Omicron variant has been predominant in Île-de-France since late February 2022.

• SI-VIC data showed a decrease in new hospitalizations, new admissions to intensive care, and COVID-19-related hospital deaths.

• Vaccination coverage is increasing slowly in the region.

Given that SARS-CoV-2 is still circulating, albeit at a declining rate, vaccination (and booster shots) for all eligible individuals remains essential and must be combined with strict adherence to other preventive measures.
