A spike in coronavirus cases in Spain has prompted new measures amid fears of a more widespread "second wave".
Catalonia has closed its nightlife for two weeks but cities outside the north-eastern region are also seeing a surge reports the BBC.
France, which has seen a rise too, has issued a travel warning and Norway is quarantining arrivals from Spain.
Germany has also hit a two-month high on new infections, as nations grapple between staving off fresh outbreaks and reopening economies.
The European rises are echoed in far bigger increases across the rest of the globe, with record daily new-infection figures of around 280,000 in both of the past two days.
"While no country is unaffected, this rise is driven by high transmission in large and populous countries in the Americas and South Asia," the World Health Organization (WHO) said in a statement on Saturday.
There have been more than 15.7 million cases globally and more than 640,000 deaths, according to Johns Hopkins University reports the BBC.
What is happening in Spain?
Barely a month after Spain ended its state of emergency, cities including Barcelona, Zaragoza and the capital Madrid have seen a surge in new infections, prompting the government to warn that a second wave could be imminent.
The government of Catalonia now says all nightclubs and late-night bars in the region are to close for the next two weeks reports the BBC.
The Spanish health ministry reported more than 900 new cases of the virus on Friday. One football team in the second division, Fuenlabrada, now has 28 confirmed cases.
The BBC's Guy Hedgecoe in Madrid says contagion among young people is a particular worry, as they have been gathering in large numbers in cities at night.
Epidemiologist Dr Daniel Lopez-Acuna told the BBC the average age of cases could rise "because the transmission is going from the youngsters to the rest of the household, and certainly the elderly".
France has warned its citizens not to travel to Catalonia while Norway has said it will start quarantining people arriving from Spain.
Belgium has banned travel to Huesca and Lleida, with recommendations against travel to a number of other areas in Spain.
Are other European nations concerned at the spikes?
Most are seeing increases and outbreaks but want to keep economies functioning and hope any second wave will be regionally limited.
