Shutting Britain's borders at the start of coronavirus's first wave could have prevented major outbreak, another study suggests
Shutting Britain's borders at the start of the coronavirus crisis may have lessened the country's catastrophic outbreak, another study has suggested. Researchers from the London School of Hygiene and Tropical Medicine modelled the impact of international travel restrictions on the spread of Covid-19. They looked at 162 countries and estimated the number of imported cases, which scientists will never know for certain due to a lack of testing early in the year. They found travels bans are most effective in countries with low transmission, or that have strong travel links with countries recording high rates of infection — but that they had a 'limited impact' in other scenarios. The UK Government blocked all travel to and from China in early February, a move which experts say undoubtedly prevented some cases of Covid being imported. But No 10 was criticised for not putting any travel restrictions on people coming from Italy or Spain, where infections were rocketing.
