The world saw the largest daily increases yet incases over the weekend, though infections slowed in China and South Korea, suggesting progress in stemming their newest outbreaks. Despite clear progress in containing the virus in some regions, especially those that saw early outbreaks, the number of new cases has soared globally in recent days.
In Brazil, the United States, Iraq and India, many hospitals are scrambling to cope.
Nearly 9 million people have been infected and more than 468,000 people have died, according to figures compiled by Johns Hopkins University. Experts say the actual numbers are much higher, given limits to testing and the presumed large share of asymptomatic cases.
Late Sunday, the World Health Organization reported the largest single-day increase in coronavirus cases by its count, more than 183,000 new cases in the prior 24 hours. Brazil tallied 54,771 and the U.S. was next at 36,617, the U.N. health agency said. India reported more than 15,400. More than two-thirds of the new deaths were reported in the Americas.
Experts say rising case counts reflect multiple factors including more testing and spreading infections.
In the U.S., experts say the resurgence in infections isn't a so-called "second wave" but a continuation of the first wave of outbreaks as the number of cases plateaus.
New cases are dipping in some parts of the country while rising mainly in the South, West and Midwest, swamping hospitals in some areas.
The coronavirus has killed about 120,000 people nationwide. As of mid-June, more than 45,500 residents and staff had died from outbreaks at nursing homes and other long-term care facilities, according to a running count by The Associated Press. That was about 40% of the total deaths.
More than 30,000 cases were reported on Friday and Saturday, with the daily totals at their highest since May 1.
In New York City, the worst affected area so far, the effort to stop the pandemic's spread through contact tracing is being hampered by the reluctance of some people with the virus to provide information to tracers.
The New York Times reported only 35% of the 5,347 city residents who tested positive or were presumed positive for COVID-19 in the first two weeks of the contact tracing program gave information about their close contacts.
But Dr. Ted Long, head of New York City's new Test and Trace Corps, defended the program Sunday and said 69% of the people who complete an interview provide contacts.
Still, the city will hit a turning point Monday, entering "Phase Two" of re-openings. For the first time in three months, New Yorkers will be allowed to dine out, though only at outdoor tables. Shoppers will be able to browse in stores, haircuts will be permitted, and kids will be allowed to climb playground monkey bars instead of their apartment walls. Office workers will be allowed to resume their commutes, though many won't yet.
Larry Silverstein, the 89-year-old World Trade Center developer, said he couldn't wait. Returning to office life and in-person teamwork brings "a joy, a fulfillment, such a sense of being able to function," he said.
"I went through 9/11. I remember people telling me we were never going to be able to get people to come back to lower Manhattan," said Silverstein, who leased the twin towers six weeks before the 2001 terror attacks destroyed them. "Never bet against New York, because New York always comes back, bigger and better than ever before."
In a grim reminder of the pandemic's ubiquitous reach, Philippine officials said Monday that Saudi Arabia's king had asked that the remains of 282 Filipino workers who perished in recent months in the oil-rich kingdom be repatriated within three days. They died of varied causes, but virus restrictions have delayed the repatriations.
In Iraq, masked workers were setting up makeshift coronavirus wards in Baghdad's vast exhibition grounds as a long-dreaded spike in infections strained its overstretched hospitals, battered by years of conflict and poor infrastructure.
Still, in East Asia there were signs of progress, as South Korea reported 17 new cases, the first time its daily increase fell to under 20 in nearly a month. The country has been reporting 40 to 50 new cases per day in the past few weeks, amid increased public activity, eased attitudes on social distancing and an uptick in imported cases.
Elsewhere in Asia, Beijing's increase was in single digits for the first time in eight days. It reported nine cases.
Even in New Zealand, which earlier said, two new cases were reported Monday among infected people arriving from India and Pakistan. The country of 5 million people now has nine active cases after having none at all earlier this month.
Many remain anxious that community transmission could resume, especially after health officials admitted havingbefore they were tested to visit a dying parent. The women later tested positive and have since isolated themselves.
