Key Points

• COVID-19: Epidemiological indicators of SARS-CoV-2 circulation in Corsica are on the rise, with the incidence rate in particular exceeding the threshold—a trend not fully explained by an increase in the number of tests. All of these factors point to an increase in viral circulation in Corsica.

• Chikungunya, dengue, Zika: 4 cases of dengue reported since the start of the season (May 1).

• Heatwave: no heatwave is forecast in the coming days, and activity in emergency departments for conditions potentially related to heat is low.

• Pollen: the allergy risk is low (2/5) and primarily involves grasses, nettles, and ragweeds.
