New clusters of the novel coronavirus are expanding in the United States and Europe as Italy replaces China as the new epicenter of a worldwide outbreak.
For most people, the new coronavirus causes only mild or moderate symptoms, such as fever and cough. For some, especially older adults and people with existing health problems, it can cause more severe illness, including pneumonia.
These are some of the latest developments on Wednesday:
States race to stop virus, as official warns of worse ahead
Governors and other leaders scrambling to slow the spread of the coronavirus stepped up bans on large public gatherings and a rapidly expanding list of universities moved classes online, as the U.S. government's top infectious-disease expert Wednesday warned that the worst is yet to come.
With cases in the U.S. topping 1,000 and the number of deaths climbing to 31, lawmakers and health officials set up containment zones and sought to limit contact with those who might be infected. The outbreak has spread to more than half the states, with Arkansas and New Mexico reporting their first cases of the virus.
"Bottom line, it's going to get worse," Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases, said on Capitol Hill.
As for how much worse, Fauci said that would depend on the ability of the U.S. to curtail the influx of travelers carrying the disease and state and community efforts to contain the outbreak. He said if mild cases of the virus are counted, the mortality rate is probably about 1 percent — "roughly 10 times more lethal than the seasonal flu."
Kentucky Gov. Andy Beshear urged churches across the state to cancel services.
"I don't believe that whether you go to church during this period of time is a test of faith," he said. "I believe God gives us wisdom to protect each other and we should do that."
In hard-hit Washington state, Gov. Jay Inslee was expected Wednesday to ban gatherings of more than 250 people in virtually the entire Seattle metro area, home to some 4 million people. The Seattle area accounts for about two-thirds of the nation's coronavirus deaths, including at least 19 from the same suburban nursing home.
Schools and houses of worship were shuttered in the New York City suburb of New Rochelle, epicenter of the nation's biggest known cluster of cases, with over 100. Gov. Andrew Cuomo said he intends to send the National Guard to help scrub public spaces and deliver food, though no troops appeared to be in place Wednesday morning.
UCLA, Yale and Stanford were among the universities announcing plans to send students home and hold classes remotely.
Chicago canceled its St. Patrick's Day parade, joining Boston and Philadelphia, while the Coachella music festival that draws tens of thousands to the California desert near Palm Springs every April was postponed. Instead of hosting 100,000 at its twice-yearly conference in Salt Lake City next month, the Church of Jesus Christ of Latter-day Saints said it will hold the gathering online and on TV, with leaders delivering speeches without any attendees.
The World Health Organization declared the virus a pandemic, or a serious, global outbreak, noting that the number of cases outside China had increased 13-fold over the past two weeks. Designating the crisis a pandemic is the WHO's way of putting countries on notice to take more aggressive action.
Meanwhile, tests by U.S. government scientists and other experts found that the virus can live in the air for several hours and on some surfaces for two to three days.
For most people, the virus causes only mild or moderate symptoms such as fever and cough. For some, especially the elderly and people with existing health problems, it can cause more severe illness, including pneumonia. Most people recover in a matter of weeks, as has happened with the majority of those infected in China, the virus' country of origin.
"If you want to be blunt, Europe is the new China," Robert Redfield, director of the Centers for Disease Control and Prevention, told Congress, meaning that the movement of people from Europe is the primary source of the virus in the U.S.
For those in the middle of a quarantine, it's an anxious time waiting for the threat to pass.
Judy Aqua, who is in her 60s, is quarantining herself at home in New Rochelle after possibly being exposed to someone with the virus.
"People are really afraid to go to the supermarket. They're afraid to go to the cleaner," she said. When her husband made a recent run to a post office, she told him to wear gloves.
Santa Clara County in California, home to San Jose and Silicon Valley, banned all gatherings of 1,000 people or more. The ban in Washington state would apply to sporting events such as Seattle Mariners baseball, according to a person who was familiar with the decision but wasn't authorized to discuss it publicly and spoke to The Associated Press on condition of anonymity.
It could be just the beginning of disruptions to sports: Some college games will be played without fans in Ohio and California, and the NCAA said it will make decisions in the coming days about its men's and women's basketball tournaments. Two conferences banned fans from their championships, and the Ivy League canceled its basketball tournaments altogether.
Massachusetts Gov. Charlie Baker declared a state of emergency as cases statewide jumped to 92. Of that number, 70 are now connected to a meeting held last month by biotech company Biogen at a hotel in downtown Boston.
A woman from suburban Houston flew home from Italy after testing positive, and now everyone on the two flights she took could be at risk. Health officials urged passengers to quarantine themselves.
Some airport workers are also dealing with the outbreak, with several Transportation Security Administration officers at the San Jose airport testing positive. All TSA employees who had contact with them over the past 14 days are being quarantined at home, the agency said.
In Oakland, California, restless passengers on a coronavirus-struck cruise ship awaited their turn to disembark. By Tuesday night, Princess Cruises said about 1,400 of the 3,500 people on board had gotten off, and efforts were underway to move them to quarantine in their home countries or at military bases in California, Texas and Georgia.
California Gov. Gavin Newsom urged the state's nearly 40 million residents to avoid sporting events, concerts and other large gatherings and strongly warned the elderly to stay away from cruise ships.
WHO declares pandemic
The World Health Organization declared that the global coronavirus crisis is now a pandemic but also said it's not too late for countries to act. It took the step expressing alarm both about mounting infections and slow government responses. By reversing course and using the charged word "pandemic" that it had previously shied away from, the U.N. health agency appeared to want to shock lethargic countries into pulling out all the stops. "We have called every day for countries to take urgent and aggressive action. We have rung the alarm bell loud and clear," said Tedros Adhanom Ghebreyesus, the WHO chief.
Beijing's city government ordered all passengers arriving in the city from overseas, regardless of their points of departure, to undergo a 14-day quarantine. The move was part of stepped-up measures to prevent the new virus first detected in China from re-entering the country following its spread across the world. The number of cases in China has been falling, with just 24 new confirmed cases reported Wednesday but five of those had arrived from Italy and one from the United States.
New cluster emerges in South Korea
While cases have been waning in South Korea, a new cluster in Seoul raised alarms. The cluster was connected to a call center in one of the busiest areas of the capital. So far, 93 people have tested positive among the call center's employees and their families, but the number could grow as hundreds more undergo testing. South Korea's caseload of 7,755 infections and 54 deaths is the fourth highest in the world after China, Italy and Iran.
A STRONG WARNING FROM GERMANY'S LEADER
German Chancellor Angela Merkel is citing expert estimates that as much as 60 percent to 70 percent of the population could be infected by the new coronavirus as she insists on the necessity of measures to slow its spread. She said the reason is because people do not yet have immunity to the virus and there are so far neither vaccines nor therapies to fight it. With some 1,300 infections and two deaths, Germany's government has recommended the cancellation of all events with more than 1,000 people, among other measures. Merkel said such measures "are giving us time" and are invaluable.
GRETA THUNBERG SAYS KEEP PROTESTING, BUT DIGITALLY
Climate activist Greta Thunberg is urging people to protest digitally rather than in person because of the coronavirus outbreak. On Twitter, the Swedish teenager told followers to "keep your numbers low but your spirits high." She said the challenge was to find new ways to create public awareness and advocate for change that don't involve creating big crowds. Ahead of upcoming climate change rallies, Thunberg said people could post photos of themselves with their signs and listed some hashtags they could use.
