'A great national trial'
"This is going to be one of the roughest two or three weeks we've ever had in our country," the president said during a lengthy and at times dark press conference at the White House. "Our country is in the midst of a great national trial."
Deborah Birx, the White House coronavirus response coordinator, and Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases, cautioned that models can change based on new information. And they said they hoped mortality from the disease could be reduced below the low end of the estimate.
"We really believe and we hope every day that we can do a lot better than that," Birx said.
But even the low end estimates would mean a significant event for the country, representing one of the nation's worst public health crises and exceeding the deaths caused by many wars. By comparison, an estimated 58,220 American soldiers died in Vietnam. From April 12, 2009, to April 10, 2010, the Centers for Disease Control and Prevention estimated 12,469 Americans died from the H1N1 flu.
About 675,000 Americans died from the 1918 influenza pandemic.
Earlier this month, as the first signs of the tumbling economy appeared, Trump suggested the guidelines could at least be relaxed by Easter, which falls on April 12. He said it would be a “beautiful” time to ease up. But over the weekend, after reviewing the projections, Trump said he decided to reverse course immediately.
Johns Hopkins University tallied more than 181,000 confirmed cases as of midday Tuesday – more than any other nation – and more than 3,600 deaths.
The president said Sunday he hoped the nation would be “well on our way to recovery” by June 1. The social distancing guidelines recommend Americans work from home, avoid groups larger than 10, don't visit nursing homes and avoid unnecessary travel.
Trump said the worst is far from over, warning of a "very, very painful two weeks" ahead.
"As a nation, we face a difficult few weeks as we approach that really important day when we’re going to see things get better," he said. "Our strength will be tested, and our endurance will be tried. This is the time for all Americans to come together and do our part."
Back when there were only few confirmed cases of coronavirus in the U.S., the Centers for Disease Control and Prevention, the U.S. Department of Health and Human Services and the U.S. Surgeon General all pled with the public urging them not to wear face masks unless they were sick or caring for someone who was sick.
Today, there are thousands of cases of COVID-19 across America — and a growing movement to encourage mask usage in the U.S., even as health-care professionals grapple a severe shortage of protective equipment, including face masks and gowns as they treat coronavirus patients.
Dr. Anthony Fauci, the director of the National Institute of Allergy and Infectious Diseases, said Tuesday that the White House Coronavirus Task Force is giving “serious consideration” to broadening the existing guidance on face masks, but he said first priority must be given to health-care workers who are currently experiencing a shortage of masks.
President Donald Trump said a day earlier “we’re not going to be wearing masks forever, but it could be for a short period of time.”
On social media, the #Masks4All campaign was started by Jeremy Howard, a distinguished research scientist at the University of San Francisco and a member of the World Economic Forum’s Global AI Council. The #Masks4All movement doesn’t just push for people to wear masks, but also to make their own face masks at home to ensure that health-care workers have access to supplies.
In an opinion piece for the Washington Post, Howard said, “The senseless and unscientific push for the general public to avoid wearing masks” should rank among the worst missteps made by policy makers.
That perspective was echoed by George Gao, director-general of the Chinese Center for Disease Control and Prevention in an interview with Science magazine.
“The big mistake in the U.S. and Europe, in my opinion, is that people aren’t wearing masks,” Gao said.
“This virus is transmitted by droplets and close contact. Droplets play a very important role — you’ve got to wear a mask, because when you speak, there are always droplets coming out of your mouth,” Gao continued. “Many people have asymptomatic or presymptomatic infections. If they are wearing face masks, it can prevent droplets that carry the virus from escaping and infecting others.”
The Moneyist: ‘All they care about is making money.’ My manager told me to remove my face mask at work. Do face masks work?
Multiple studies have indicated that people may display few symptoms but have the coronavirus, while others may be contagious before they begin to display symptoms. These asymptomatic individuals have complicated government efforts to contain the spread of the coronavirus across the globe.
Some previous research has concluded that face masks have helped reduce contagion by reducing droplets being sprayed into the air during flu season; another Japanese-based study says this works when paired with vaccination, not an option in this case. This study says N95 medical-grade masks do help filter viruses that are larger than 0.1 micrometers (One micrometer, um, is one millionth of a meter.) The coronavirus is 0.125 um.
Proponents of face masks also point to the anecdotal evidence from countries in East and Southeast Asia, including South Korea and Taiwan, that have been able to slow the spread of the novel coronavirus and flatten the curve more effectively than in countries like the U.S., Spain and Italy.
Mask usage is more ubiquitous in these countries in general as a hygienic practice even outside of instances of global disease outbreaks. “In all of these countries, all of which were hit hard by the SARS respiratory virus outbreak in 2002 and 2003, everyone is wearing masks in public,” Howard wrote.
Recently, some Western countries have required residents to wear face masks. The Czech Republic, Slovakia and Bosnia-Herzegovina now require people to wear masks in public, while nearby Austria requires their use in grocery stores.
KK Cheng, a public-health expert and professor at the University of Birmingham in the U.K, said he wears a mask when he goes to the supermarket and supports Austria’s decision to mandate masks there.
“I think it’s a good idea because trips to the supermarket are the main exposure to the virus,” especially in areas where they are the only businesses that are open, he said.
The World Health Organization and the CDC continue to stand by their recommendations from earlier in the coronavirus outbreak. They argue that mask usage should be limited to people who have COVID-19 or may have contracted the illness and their caregivers, including health-care workers.
“There is no specific evidence to suggest that the wearing of masks by the mass population has any particular benefit,” Dr. Michael Ryan, WHO’s top emergencies expert, said during a press conference Monday.
Similarly, the CDC still “does not recommend that people who are well wear a face mask to protect themselves from respiratory illnesses, including COVID-19.”
“You should only wear a mask if a health-care professional recommends it,” the CDC said in a statement online. “A face mask should be used by people who have COVID-19 and are showing symptoms. This is to protect others from the risk of getting infected.”
But in a comment published in The Lancet, a medical publication, a group of researchers from Hong Kong argued that the lack of studies proving masks to be effective didn’t mean they weren’t.
“There is an essential distinction between absence of evidence and evidence of absence,” they wrote. “Face masks are widely used by medical workers as part of droplet precautions when caring for patients with respiratory infections. It would be reasonable to suggest vulnerable individuals avoid crowded areas and use surgical face masks rationally when exposed to high-risk areas.”
