The Sciensano public health institute reported an excess mortality rate of 47 percent, marking the highest excess mortality since records began in 2000.

## Heatwave Impact

Although Belgium did not officially break its temperature records for June, temperatures in Brussels reached 35°C for several consecutive days, with local readings climbing to between 38°C and 40°C. The peak in excess mortality was observed on June 27 and 28.

## Upcoming Heatwave

A new heatwave is expected in Belgium in the coming days, with temperatures potentially exceeding 30°C for five consecutive days starting Saturday. This forecast raises concerns about further increases in heat-related deaths.

## Why This Matters

The significant increase in excess deaths highlights the severe impact of heatwaves on public health. For Bangladesh, which frequently experiences extreme heat, understanding the effects of such weather events is crucial for preparing healthcare systems and implementing preventive measures.

## Background and Context

Heatwaves are becoming more frequent and intense due to climate change. This trend underscores the need for better preparedness and response strategies to protect vulnerable populations. In Belgium, as in many other countries, heatwaves disproportionately affect the elderly and those with pre-existing health conditions.
