Italy confronts record heat wave, red alerts issued for eleven cities FAST-MOVING

Italy heat wave red alert ECDC infection risk

Italy is undergoing its fourth heat wave of the summer of 2026, driven by an African anticyclone that brings hot, humid air over the Mediterranean. Temperatures are expected to soar up to 40‑44 °C in many parts of the country, with the highest peaks forecast for Sicily, Sardinia and inland areas. On 31 July the Italian Ministry of Health raised the health‑risk level to red (level 3) for eleven cities – Bolzano, Campobasso, Civitavecchia, Florence, Frosinone, Latina, Perugia, Rieti, Rome, Turin and Viterbo – after earlier red alerts for Campobasso, Perugia and Rieti on 30 July. The alert advises limiting outdoor activity, staying hydrated and protecting vulnerable groups. The heat wave is projected to last at least ten days, potentially into early August. The European Centre for Disease Prevention and Control warned that prolonged heat can heighten the risk of food‑borne, Vibrio, mosquito‑borne and tick‑borne infections across Europe.
