Key Points

In Week 03 in Île-de-France, viral circulation remained very intense in the region. The public health situation appeared to be improving but remained dire.

• The crude incidence rate stood at 3,276 cases per 100,000 inhabitants and decreased for the second consecutive week, though it remained very high amid a decline in testing rates.

• The positivity rate continued to rise, reaching 28.2%, its highest level since the start of the epidemic.

• The Omicron variant (21K, B.1.1.529), which has been the dominant strain in Île-de-France since Week 51, continued to spread rapidly in the region.

• SI-VIC data showed a decline in new hospitalizations and new ICU admissions. However, COVID-19-related hospital deaths continued to rise.

• Vaccination coverage with at least one dose stood at 75.7%, 74.4% for the full course, and 47.0% for the booster dose.

Given the high level of viral circulation, vaccinating all eligible individuals remains essential and must be combined with strict adherence to other preventive measures.
