A new study at Aberdeen University has suggested international travel had the biggest impact on death rates during the first wave of Coronavirus.
Research led by academics at the Granite City institution found an increase of a million international arrivals was associated with a 3.4% spike in mean daily Covid deaths.
Findings come after a dedicated team of professors, academics and scholarship students examined a range of factors including border arrivals, population density, the percentage of people living in urban areas and many others – which were then compared with the mortality rates across 37 of the worst hit countries.
