WHO reports largest oneday rise in COVID-19 cases so far.

Brazil biggest contributor with 54,771 COVID-19 diagnoses in 24 hours; U.S. next with 36,617

Geneva — The World Health Organization on Sunday reported the largest single-day increase in coronavirus cases by its count, at more than 183,000 new cases in the latest 24 hours.

The UN health agency said Brazil led the way with 54,771 cases tallied and the U.S. next at 36,617. Over 15,400 came in India.

Experts said rising case counts can reflect multiple factors including more widespread testing as well as broader infection.

Overall in the pandemic, WHO reported 8,708,008 cases — 183,020 in the last 24 hours — with 461,715 deaths worldwide, with a daily increase of 4,743.

More than two-thirds of those new deaths were reported in the Americas.

In Spain, officials ended a national state of emergency after three months of lockdown, allowing its 47 million residents to freely travel around the country for the first time since March 14. The country also dropped a 14-day quarantine for visitors from Britain and the 26 European countries that allow visa-free travel.

But there was only a trickle of travelers at Madrid-Barajas Airport, which on a normal June day would be bustling.

“This freedom that we now have, not having to justify our journey to see our family and friends, this was something that we were really looking forward to,” Pedro Delgado, 23, said after arriving from Spain’s Canary Islands.

Spanish Prime Minister Pedro Sánchez urged people to take maximum precautions: “The virus can return and it can hit us again in a second wave, and we have to do whatever we can to avoid that at all cost.”

The U.S. has the world’s highest number of reported infections, over 2.2 million, and the highest death toll, at about 120,000, according to Johns Hopkins. The virus appears to be spreading across the West and South. Arizona reported over 3,100 new infections, just short of Friday’s record, and 26 deaths. Nevada also reported a new high of 445 cases.
