TOKYO (AP) — The coronavirus has claimed its first victim in the United States as the number of cases shot up in Iran, Italy and South Korea and the spreading outbreak shook the global economy.

Governments stepped up efforts to contain the disease. Saudi Arabia closed Islam’s holiest sites to foreign pilgrims. In Japan, professional baseball teams played in deserted stadiums. The French government advised the public to forgo customary greeting kisses.

Ireland and Ecuador among the countries reporting their first cases Saturday. More than 85,000 people worldwide have contracted the virus, with deaths topping 2,900.

China recorded 573 new virus cases and 35 more deaths in the 24 hours through midnight Saturday, according to the National Health Commission. That raised the total for the country where the disease emerged in December to 2,870 deaths and 79,834 cases.

In the United States, a man in his 50s in suburban Seattle became the first coronavirus death on U.S. soil. Officials say they aren’t sure how the man acquired the virus because he had not traveled to any affected areas.

“Additional cases in the United States are likely, but healthy individuals should be able to fully recover,” President Donald Trump said. Officials announced heightened warnings about travel to certain regions of Italy and South Korea as well as a ban on travel to Iran.

Many cases of the virus have been relatively mild, and some of those infected are believed to show no symptoms at all. But that can allow for easier spread, and concern is mounting that prolonged quarantines, supply chain disruptions and a sharp reduction in tourism and business travel could weaken the global economy or even cause a recession.

South Korea, the second hardest hit country after China, reported 376 new cases on Sunday morning, raising its total to 3,526. Most of the cases in South Korea have been reported in the southeastern city of Daegu and nearby towns.

Italian authorities say the country now has more than 1,100 coronavirus cases, with 29 deaths so far.

Iran is preparing for the possibility of “tens of thousands” of people getting tested for the virus as the number of confirmed cases spiked again Saturday, an official said. So far, the virus and the COVID-19 illness it causes have killed 43 people out of 593 confirmed cases in Iran.

Researchers reported the death rate may be lower than initially feared as more mild cases are counted.

A study by Chinese researchers published Friday in the New England Journal of Medicine analyzing 1,099 patients at more than 500 hospitals throughout China calculated a death rate of 1.4%, substantially lower than earlier studies that focused on patients in the central city of Wuhan, where it started and has been most severe.

Assuming there are many more cases with no or very mild symptoms, “the case fatality rate may be considerably less than 1%,” U.S. health officials wrote in an editorial in the journal.

That would make the new virus more like a severe seasonal flu than a disease similar to its genetic cousins SARS, severe acute respiratory syndrome, or MERS, Middle East respiratory syndrome.

Also Saturday, a survey of Chinese manufacturers showed activity plunged in February by a wider margin than anticipated, adding to the virus’s mounting economic toll.

The monthly purchasing managers’ index issued by the Chinese statistics agency and an industry group fell to 35.7 from January’s 50 on a 100-point scale on which numbers below 50 indicate activity contracting.

Japanese Prime Minister Shinzo Abe announced a 270 billion yen ($2.5 billion) emergency economic package to help fight the virus. Abe said at a news conference that Japan is at critical juncture to determine whether the country can keep the outbreak under control ahead of the Tokyo summer Olympics.

Abe, who earlier announced plans to close all schools for more than a month through the end of the Japanese academic year sparked public criticism, said the package includes financial support for families and their employers affected by the closures.

“Frankly speaking, this battle cannot be won solely by the efforts of the government,” Abe said. “We cannot do it without understanding and cooperation from every one of you, including medical institutions, families, companies and local governments.”

Even in isolated, sanctions-hit North Korea, leader Kim Jong Un called for stronger anti-virus efforts to guard against COVID-19, saying there will be “serious consequences” if the illness spreads to the country.

In other areas caught up in the outbreak, eerie scenes met those who ventured outside.

Streets were deserted in the city of Sapporo on Japan’s northernmost main island of Hokkaido, where a state of emergency was issued until mid-March. Tokyo Disneyland and Universal Studios Japan announced they would close, and big events were canceled, including a concert series by the K-pop group BTS.

In France, the archbishop of Paris advised parish priests not to administer communion by placing the sacramental bread in worshippers’ mouths. Instead, priests were told to place the bread in their hands. The French government cancelled large indoor events.

Saudi Arabia closed off Islam’s holiest sites in Mecca and Medina to foreign pilgrims, disrupting travel for thousands of Muslims already headed to the kingdom and potentially affecting plans later this year for millions more ahead of the fasting month of Ramadan and the annual hajj pilgrimage.

Tourist arrivals in Thailand are down 50% compared with a year ago. In Italy, which has the most reported cases of any country outside of Asia, hotel bookings are falling. Premier Giuseppe Conte raised the specter of recession.

Full Coverage: Virus Outbreak

The head of the World Health Organization on Friday announced that the risk of the virus spreading worldwide was “very high.” U.N. Secretary-General Antonio Guterres said the “window of opportunity” for containing the virus was narrowing.

Economists have forecast global growth will slip to 2.4% this year, the slowest since the Great Recession in 2009, and down from earlier expectations closer to 3%. For the United States, estimates are falling to as low as 1.7% growth this year, down from 2.3% in 2019.

Despite anxieties about a wider outbreak in the U.S., Trump has defended measures taken and lashed out at Democrats who have questioned his handling of the threat.

Trump has accused Democrats of “politicizing” the coronavirus threat and boasted about preventive steps he’s ordered in an attempt to keep the virus from spreading across the United States.
