WASHINGTON, D.C. — U.S. officials estimate that 20 million Americans have been infected with the coronavirus since it first arrived in the United States, with millions never knowing they had it.Thursday's estimate is roughly 10 times the 2.3 million cases that have been confirmed in the U.S.“Our best estimate right now is that for every case that we’ve reported, there were actually 10 other infections,” said the director of the Centers for Disease Control and Prevention (CDC), Robert Redfield, during a phone briefing with reporters Thursday. Redfield said that estimate comes from analyzing blood samples from across the country for the presence of antibodies to the virus.Twenty million infections means that only about 6% of the nation’s 331 million people have had the virus, leaving the vast majority of the population still susceptible.“This is still serious,” Redfield said. “But I’m asking people to recognize that we’re in a different situation today than we were in March or April,” with more cases today in younger people who are not as likely to develop serious illness or die from infection, he said.The news comes as the Trump administration works to tamp down nationwide concern about the COVID-19 pandemic at a time when about a dozen states are seeing worrisome increases in cases.Also on Thursday, the CDC announced that it was broadening its list of people who are at a higher risk of getting seriously ill from the coronavirus. The CDC has removed the specific age threshold for severe COVID-19 illness. It now warns that among adults, risk increases steadily as you age, and it’s not just those over the age of 65 who are at increased risk.The agency has also updated its list of underlying medical conditions that increase the risk of severe illness from the coronavirus. 1806

We're still learning about COVID-19, but when it comes to how long the illness lasts, patients generally feel sick around the same amount of time.Most coronavirus patients have mild to moderate illness and recover quickly. Illness generally lasts for about two weeks, but that can vary widely.Older, sicker patients tend to take longer to recover. That includes those with high blood pressure and other chronic diseases.One U.S. study found that almost half of non-hospitalized patients over age 50 still had symptoms at least two weeks after becoming ill.Among those sick enough to be hospitalized, a study in Italy found that 87% of patients still had symptoms two months after getting sick. Lingering symptoms included fatigue and shortness of breath.Click here to learn more on the CDC’s website. 808

WASHINGTON (AP) — The traditional White House gingerbread house isn't exactly a house this year. It's a massive, sugary replica of the entire National Mall.The pastry creation — featured at Monday's unveiling of the White House holiday decorations — required 225 pounds of dough, 25 pounds of chocolate and 20 pounds of white icing. It includes replicas of the Capitol, the Lincoln and Jefferson memorials, the Washington Monument and the White House, complete with tiny green wreaths with red ribbons on each window.White House pastry chefs have created gingerbread houses during the holidays since the early 1970s. The first one depicted a Christmas village. Another was a replica of President Bill Clinton's boyhood home in Arkansas."American Treasures" is the theme of this year's White House holiday decor, designed by first lady Melania Trump, who tweeted a video showing her walking amid the display. Decorations in the ornate East Room are meant to highlight the diversity and ingenuity of American architecture.Four custom-made mantelpieces feature the skylines of New York, St. Louis, Chicago and San Francisco. Seventy-two handmade paper ornaments representing six regions across the nation adorn four 14-foot fir trees. In the library, trees are decorated with ornaments from all states and territories.In the China Room there are three tables recreated from previous state dinners during the Theodore Roosevelt, John F. Kennedy and Trump administrations using, china and glassware from the White House permanent collection. A place card for President Donald Trump is next to one for "Mrs. Macron," French President Emmanuel Macron's wife, Brigitte.Upstairs in the Green Room, there are decorations representing an American cornucopia with fruits, vegetables and grains adorning a tree.The 18-foot official White House Christmas tree stands tall in the center of the Blue Room. The Fraser fir from North Carolina is decorated with more than 500 feet of blue velvet ribbon embroidered in gold with each state and territory.The Red Room features ornaments and two wreaths made of pencils stamped with "Be Best," Mrs. Trump's youth initiative.Patriotism is on display in the Grand Foyer and Cross Hall. More than 14,000 red ornaments hang on the branches of 29 trees. Hidden projectors cast silhouettes of pine and other holiday greenery on the ceilings.From their portraits on the walls of the corridor, Presidents John F. Kennedy, Jimmy Carter, George H.W. Bush and Ronald Reagan gaze down on the holiday spectacle. 2534

  

WAVELAND, Miss. — Storm-weary Gulf Coast residents are preparing for a new weather onslaught as Tropical Storm Sally churns northward. Forecasters from the National Hurricane Center in Miami said Sally is expected to become a hurricane on Monday and reach shore by early Tuesday, bringing dangerous weather conditions including risk of flooding to a region stretching from the western Florida Panhandle to southeast Louisiana. Louisiana Gov. John Bel Edwards urged people to prepare for the storm immediately. He also said there are still many from southwestern Louisiana who evacuated from Hurricane Laura into New Orleans — exactly the area that could be hit by Sally.As the Gulf Coast braced for Sally, Bermuda was hunkered down and riding out the effects of Hurricane Paulette. That storm — with maximum sustained winds of 90 mph as of 4 a.m. ET — was hovering above the Atlantic island nation as of Monday morning. The storm is expected to impact Bermuda throughout the day on Monday before moving west on Tuesday.Also on Monday, Tropical Storm Teddy formed in the eastern Atlantic Ocean. According to National Hurricane Center forecasts, it's not expected to make landfall until next week if it doesn't dissipate by then.Teddy marks the 19th named storm of 2020. According to the NOAA, the record for most named storms in one year came in 2005, when 27 storms of at least Tropical Storm level formed.The NHC is currently monitoring eight systems in the Atlantic and Caribbean. 1491
