Fears of a second coronavirus wave in Europe are growing as several countries have seen dramatic increases in the number of cases.
Croatia, Slovenia, Malta, Austria, Hungary, France and Greece all had spikes of more than 70% during the week of 10-16 August compared with the week before, the latest weekly data from the European Centre for Disease Prevention and Control has found.
The most dramatic rise was in Croatia, with a 174% increase in the rate of infections, from 7.8 cases per 100,000 to 21.5, while Slovenia increased by 102.6% but from 3.7 to 7.4 cases per 100,000.
Denmark, Switzerland, Italy and Norway all had increases of between 46.9% and 59.4%.
Travellers from the most popular tourist destinations out of the top 11 countries with large spikes in Europe have to self-isolate on their return to the UK.
Croatia and Austria were added to the quarantine list today, along with Trinidad and Tobago in the Caribbean, with the rule coming into effect from 4am on Saturday.
France, Malta and the Netherlands were placed on the list last week due to spikes.
Spain, which has been on the list since 26 July, continues to have the highest rate – 60.6 cases per 100,000 people – but only increased by 10.1% in those weeks.
On Thursday, it reported 3,349 new cases, with more than 1,000 of those in the capital, Madrid.
