ECDC warns heat waves raise infectious disease risk across Europe

heat waves infectious disease risk ECDC Europe mosquito‑borne illnesses

The European Centre for Disease Prevention and Control (ECDC) says that rising temperatures and longer heat waves across Europe are creating conditions that promote the spread of infectious diseases. Warmer weather accelerates bacterial growth in food, increasing the likelihood of food‑borne illnesses, while humid conditions favour the multiplication of microbes, as noted by the World Health Organization.

Mosquito‑borne illnesses such as dengue, chikungunya and West Nile virus are becoming more common, with cases reported this year in Greece, Italy, North Macedonia, Romania and Spain. The agency recommends basic hygiene measures – washing fruit and vegetables, keeping raw and cooked foods separate, cooking thoroughly and storing food at safe temperatures – and mosquito‑control steps like using window screens, air‑conditioning and eliminating standing water. Warm coastal waters also foster Vibrio bacteria, raising the risk of vibriosis from seafood.

Health experts added that heat can affect blood pressure: initial vasodilation lowers pressure, but a secondary stress response may raise it, which can be hazardous for vulnerable groups such as the elderly and those with pre‑existing hypertension.
