In the version of this article initially published, there was a typographical error in the second paragraph of the Discussion, where in the text now reading “As a reference, a previous study [Epidemiology 34, e5–e6 (2023)] applied similar epidemiological models to daily temperature and mortality data for Spain only, and found that the summer heat-related mortality burden was 6% higher (that is, 12,054 deaths) than the one reported here…,” 6% originally read “10%” and 12,054 originally read “12,504”. The errors have been corrected in the HTML and PDF versions of the article.
