CHThe latest mortality data from Switzerland indicates that the heatwave last week caused approximately 200 additional deaths among people over 65 years old, exceeding the expected seasonal death rate by around 15 percent. This figure is lower than during previous heatwaves, such as in 2015, but higher than in 2022. The causes of these excess deaths are typically not directly attributed to heat on death certificates, as individuals often die from pre-existing conditions like heart attacks, circulatory failure, or respiratory diseases exacerbated by high temperatures. While individual cases rarely show a direct link between heat and death, statistical trends clearly correlate increased mortality with heatwaves. The Federal Statistical Office (BFS) calculates this by comparing current mortality rates to expected values based on historical seasonal patterns and trends. However, the data has a delay of about ten days, meaning recent deaths are not yet included. Existing heat action plans implemented at the cantonal level appear to have reduced excess mortality compared to past summers, though there is currently no nationwide uniformity in these measures.
Bias read (Center): The article presents factual data on mortality rates linked to a heatwave, discusses the methodology used by the Federal Statistical Office, and mentions existing heat action plans without overtly favoring any political stance. It provides balanced information on the challenges of attributing deaths
