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.
Tiberiu Pana, one of the authors of the study, said: "We found that international travel was the strongest predictor of mortality increase."Our assessment of available data indicates that very early restrictions on international travel might have made a difference in the spread of the pandemic in western Europe, including the UK."These findings are particularly important as the world looks to control future waves and strains of the Covid-19 pandemic and prevent related deaths."
Lead author, Prof Phyo Myint, director of the Aberdeen Clinical Academic Training Scheme said: "This is important research, led by medical students, who have demonstrated robust use of publicly available data to inform future policies in preventing the spread of Covid-19."
