Key Points

In week 26 (June 28–July 4), epidemiological indicators of SARS-CoV-2 circulation showed an increase in the number of COVID-19 cases and a slowdown in the improvement of the situation in Île-de-France. Declines in the indicators were less pronounced, some were rising again, and detection of the Delta variant was rising sharply in the region.

In Île-de-France, after 12 consecutive weeks of decline, the regional incidence rate for Week 26 was rising, reaching 37 cases per 100,000 inhabitants. The testing rate increased while the positivity rate remained relatively stable. Compared to other regions, the incidence rate in Île-de-France remained the highest.

The number of reported new hospitalizations and the number of admissions to intensive care units continued to decline in Week 26, but at a less pronounced rate than in previous weeks. The number of reported deaths in hospitals among COVID-19 patients remained stable in Week 26.

Although vaccination in Île-de-France continued, the rate of progress slowed among adults over 18 years of age. As of July 6, vaccination coverage with at least one dose was 50.9%, and coverage for the full vaccination regimen was 36.7%. It is important to encourage vaccination among all individuals aged 18 and older, with specific measures to reach older adults, with the goal of achieving a sufficient level of herd immunity.

Given the rise in COVID-19 cases and the slowing decline in indicators in Week 26, amid the continued lifting of collective restriction measures, incomplete vaccination coverage, and the circulation of variants of concern, it is essential to maintain a high level of adherence to individual prevention measures, testing, and isolation of cases and at-risk contacts.
