(Reuters) - The World Health Organization on Wednesday urged governments and local authorities to set up a strong surveillance system for people who are most at risk of severe symptoms from a heatwave that is baking the northern hemisphere.
People with cardiovascular and respiratory diseases and diabetes, as well as pregnant women, children and homeless people, are seen as the most vulnerable to heatwaves that have scorched parts of Europe, Asia and the United States this week.
