Covid-19: International travel 'biggest impact' on deaths

International travel had the biggest impact on Covid death rates for countries hit in the pandemic's first wave, a study has found. Researchers in Aberdeen focused on the world's worst affected 37 countries. They examined factors including border arrivals, population density, the percentage of people living in urban areas, age, and health issues. The team said early restrictions on international travel could have made a difference in the spread. The study looked at counties including America, the UK, Spain, France, Italy and Brazil, and focused on the early stages of the pandemic. They found an increase of one million international arrivals was associated with a 3.4% rise in the mean daily increase in Covid-19 deaths.
