Coronavirus is spreading far faster in Spain than in the rest of Europe, confronting the country with a race against time to bring the outbreak under control before the return to school and work next month following the holiday season. Figures published by the European Centre for Disease Prevention and Control, an EU agency, on Thursday indicated that in the previous 14 days Spain had reported about 139 new Covid-19 cases per 100,000 of population.

Apart from Malta, no other European country had a ratio above 100, and the Spanish figures compare with ratios of 46 in France and 21 in the UK. In three districts of Madrid, the Spanish region with most cases, the equivalent ratio is above 400  and in one it is almost 600. “No one should be confused: things are not going well,” Fernando Simon, the doctor leading the country’s effort against the pandemic, said on Thursday evening, as he acknowledged that in some areas of the country the spread of the virus was out of control.

National and regional officials largely blame the speed of the virus’s resurgence on uncontrolled groups of youths drinking and socialising – as well as gatherings of family members –  and are beginning to warn that despite months of planning, pupils may not be able to return to classes in full. Dr Simon pleaded for social media influencers to use their clout with young people to persuade them of the dangers of the virus. “We can’t allow this to go on,” he said. “I understand that people want to party, but there are lots of ways to party.”

Critics say that Madrid and Spain as a whole need to step up their effort to track and trace the virus spread. In Madrid, where more than 2,600 new cases were reported on Thursday, there are about 550 trackers. “Unless citizens take responsibility, in terms of staying at home if they have been in contact [with someone infected], we could have the best tracking in the world and it won’t be enough,” Enrique Ruiz Escudero, the Madrid region’s top health official, told the Financial Times. “Most of the outbreaks we have detected have been family or social gatherings when people relax and think they can’t be infected.”

With the disease resurgent in a city that has been largely deserted for the beach, the challenge is to avoid a disastrous further surge when people return to schools and work in around two weeks’ time, as well as during the autumn flu season.

As is the case in countries such as France and Germany, the number of daily cases recorded in Spain has already returned to levels not seen since spring. On Thursday, the health ministry reported more than 7,000 new cases and said that 122 people had died in the previous week. This compares with a death toll
