Key Points

COVID-19

Regional epidemic monitoring indicators have stabilized:

• stable regional incidence rate;

• stable regional testing rate;

• Stable regional positivity rate;

• Low COVID-19-related activity at the SOS Médecins association;

• Low COVID-19-related activity in emergency departments;

• Hospitalizations across all departments showing a steady increase;

• Hospitalizations in intensive care or critical care units are decreasing;

• 4 new clusters in S05.

The regional incidence rate, at 112 per 100,000 inhabitants, is stable but still masks a difference between the island’s two departments. It
remains above the alert threshold of 50 per 100,000 inhabitants. The testing rate is stable (4,538 per 100,000 inhabitants). The positivity rate is stable (2.6%, as in S04).

The difference between the departments is reflected in hospitalizations. In Southern Corsica, the total number of inpatients across all departments is decreasing, and there are still no patients in intensive care or critical care, whereas in Northern Corsica, the total number of inpatients across all departments has stabilized and the number in intensive care or critical care has decreased.
