Desperate travelers choked European border crossings Wednesday after countries implemented strict controls to try to slow the spread of the coronavirus, which has now infected more than 200,000 people worldwide and killed more than 8,000.
In releasing the new figures, Johns Hopkins University also said more than 82,000 people recovered from the virus, which causes only mild or moderate symptoms such as fever and cough for most people, although severe illness is more likely in the elderly and those with existing health problems.
European leaders have closed borders to nonessential traffic, while leaving many frontiers open to cross-border workers and trucks carrying critical goods like food and medicine. That has led to massive backups of travelers and trucks alike.

But by early Wednesday on the Austrian side, trucks were backed up for 28 kilometers (17 miles) and cars for 14 kilometers (nearly 9 miles) as rules allowing only Hungarians or cargo trucks to cross kicked back in.
In a second attempt, Hungary again opened the borders Wednesday through Thursday morning to allow Romanians, Bulgarians and Serbians to transit.

"We are at the start of the epidemic," he said. "We are 1-2 weeks behind Italy. "

"If we don't work, we don't eat," said Aguirre.
