Key Points

Arboviral Diseases

• Two imported cases of dengue fever in Corsica have been reported since May 1 (total remains unchanged).
• Two locally acquired cases of West Nile virus infection have been recorded this season, one in each of the island’s departments.

Acute Respiratory Infections

• Lower ARI: baseline level
  • Increased activity at SOS Médecins, driven in particular by a sharp rise in cases of acute bronchitis. Activity remains stable in emergency departments.
• Influenza and influenza-like illnesses: baseline level, very low activity;
• Bronchiolitis: baseline level, activity decreasing, low case numbers. However, the rhinovirus, which can cause bronchiolitis, is currently circulating in Corsica as well as on the mainland;
• COVID-19: SARS-CoV-2 is actively circulating on the island, as on the mainland, but the impact on the use of emergency care remains low.

Mortality

• No unusual trends in the number of deaths from all causes in the region, whether in civil registry data (S42) or electronic death certification data (S43) (graphs not shown for either source).
