PROBLEM: Paragraph: The Midwest was the hardest-hit region, as temperatures  plunged below zero Fahrenheit (minus 18 degrees Celsius). By nightfall the mercury was hovering at 0F in Chicago, 7F (minus 14C) in Detroit and minus 21f (minus 29C) in Minneapolis. Local television pictures showed the Chicago River and Lake Michigan filled with chunks of ice. The brutal blast known as the polar vortex is a stream of cold air that spins around the stratosphere over the North Pole, but whose current has been disrupted and is now pushing south into the United States. Officials warned Chicago residents, accustomed to chilling winters, to expect an unusually deep and dangerous freeze. Even the city’s supply of its signature deep-dish pizza was affected: The Lou Malnati’s chain announced it would stop taking delivery orders at 8 p.m. on Tuesday. “This could possibly be history-making,” said Ricky Castro, a National Weather Service meteorologist in Romeoville, Illinois. As much as two feet (60 cm) of snow was forecast in Wisconsin, and six inches (15 cm) in Illinois. Snow was expected through Wednesday from the Great Lakes region into New England. Some Chicago residents found warmth inside the Harold Washington Library Center, which planned to stay open on Wednesday. Gilbert Rothschild, 79, walked through a corridor wearing three sweaters and an undershirt underneath his parka. “The more layers, the more you’re insulated,” he said. Rothschild, the president of a liquor retailer, said he planned on keeping his stores open on Wednesday, figuring customers who were not working might want to pick up something to keep them feeling warm at home. Many Midwest cities opened warming shelters. Regional governments closed hundreds of schools and airlines canceled more than 2,000 flights, according to the Flightaware flight tracking website. Many had been destined for Atlanta, where the National Football League’s Super Bowl will take place on Sunday. Amy Patterson, a vice president at the Atlanta Super Bowl Host Committee, said there would still be time for fans to fly to Atlanta for the game, with the National Weather Service forecasting a high of a balmy 58F (14C) on Sunday. A low of minus 10F (minus 23C) was forecast in Chicago and elsewhere in northern Illinois on Wednesday. But with the wind chill factored in, temperatures will feel as low as minus 50F (minus 46C) through Thursday, the National Weather Service reported. Temperatures could reach lows of minus 30F to minus 40F (minus 34C to minus 40C) in parts of the Northern Plains and Great Lakes on Wednesday, the NWS said. The freezing weather may have killed a man in Rochester, Minnesota, who was found dead outside his home on Sunday, according to a report by WCCO, a local CBS affiliate. Rochester police officials did not respond to a request for comment. Jim Hayes, a National Weather Service meteorologist, warned that frostbite was possible within 10 minutes in the intense cold. For many across the region, life ground to a halt. In Chicago, home to the nation’s third-largest school system, officials plan to cancel classes for all 360,000 students on Wednesday due to the weather. Detroit also said all public schools would close, and Michigan State University said it would suspend classes, only the seventh time it has done so because of weather since 1855. The Chicago Zoological Society said it would shut Brookfield Zoo for only the fourth time in its 85-year history on Tuesday and Wednesday. According to the National Weather Service, the coldest recorded temperature in Chicago was minus 27 degrees (minus 33C) on Jan. 20, 1985. Officials in Des Moines, Iowa, opened warming shelters, but also suggested residents could stay warm inside shopping malls. In Georgia, Governor Brian Kemp shut government offices in 35 counties on Tuesday, and schools across parts of the state were also closed. In Fargo, North Dakota, where the temperature dropped to minus 24F (minus 31C), Dan Hallock, an advertising executive, marveled that people were still working outside as he bought coffee. “The garbage men of Fargo have my utmost respect,” he said. Claim: Polar vortex freezes U.S. Midwest with snow, dangerously cold air.

SOLUTION: A blast of Arctic air from the polar vortex brought dangerous, bone-chilling cold to a wide swath of the United States on Tuesday, stretching from the Dakotas through Maine, with snow expected as far south as Alabama and Georgia.

PROBLEM: Paragraph: The footage, said to be filmed in January at Planned Parenthood clinics in Falls Church, Charlottesville and Roanoke, Virginia, is the latest in a series of videos made public by Live Action, a California-based group that opposes abortion. Live Action said in a statement that the videos are evidence Planned Parenthood is “willing to aid and abet the sexual trafficking and exploitation of minors and young women.”   Planned Parenthood said the undercover videos are part of a coordinated lobbying effort to advance legislation that would take away funding from the family planning organization. The three videos, one at each clinic, show a man saying he’s involved in sex work and manages teenage girls ask questions about prices and identification requirements for sexually transmitted disease testing, birth control and abortions. In each case he asks if the conversations are confidential. In the videos, Planned Parenthood employees answer questions about health services offered at the clinic and explain requirements associated with different procedures. “It’s very clear to us that these tapes show health professionals doing their job,” said Planned Parenthood spokesman Stuart Schear of the new footage. “What the tapes don’t show is that after these unusual encounters, these health professionals went to their superiors and reported they had unusual encounters with a suspicious individual and Planned Parenthood managers reported their suspicions to local authorities,” Schear said. Planned Parenthood has said previously that the FBI is reviewing evidence and photos related to the encounters. All of the undercover videos were filmed during the same week. The first one, released on Tuesday, focused on a clinic in central New Jersey. The New Jersey clinic employee captured on film was later fired for her behavior. Planned Parenthood said it notified both local and national authorities after the string of unusual visits, which occurred within one week in at least 12 centers in six states, including New Jersey and Virginia. In January, Planned Parenthood said it alerted U.S. Attorney General Eric Holder that a series of health centers had been approached by visitors whose comments indicated involvement in sex trafficking of minors. Live Action’s founder, Lila Rose, said her group will send the Virginia footage to state law enforcement officials and Virginia Attorney General Ken Cuccinelli. Cuccinelli said in a statement released Friday that he plans to review the footage, noting that what he has seen so far “is very disturbing.”   Meanwhile, New Jersey’s Attorney General Paula Dow is aware of the video and has referred the matter to the Division of Criminal Justice for review, spokesman Paul Loriquet said earlier in the week. Claim: Anti-abortion group releases more video of Planned Parenthood.

SOLUTION: An anti-abortion group released on Friday three more undercover videos, which it said show Planned Parenthood employees helping a man posing as a pimp get abortions and birth control for underage girls.

PROBLEM: Paragraph: Jeong Eun-kyeong, director of the Korea Centers for Disease Control and Prevention (KCDC), told a briefing that the virus may have been “reactivated” rather than the patients being re-infected. South Korean health officials said it remains unclear what is behind the trend, with epidemiological investigations still under way. The prospect of people being re-infected with the virus is of international concern, as many countries are hoping that infected populations will develop sufficient immunity to prevent a resurgence of the pandemic. The South Korean figure had risen from 51 such cases on Monday. Nearly 7,000 South Koreans have been reported as recovered from COVID-19, the disease caused by the new coronavirus. “The number will only increase, 91 is just the beginning now,” said Kim Woo-joo, professor of infectious diseases at Korea University Guro Hospital. The KCDC’s Jeong raised the possibility that rather than patients being re-infected, the virus may have been “reactivated”. Kim also said patients had likely “relapsed” rather than been re-infected. False test results could also be at fault, other experts said, or remnants of the virus could still be in patients’ systems but not be infectious or of danger to the host or others. “There are different interpretations and many variables,” said Jung Ki-suck, professor of pulmonary medicine at Hallym University Sacred Heart Hospital. “The government needs to come up with responses for each of these variables”. South Korea on Friday reported 27 new cases, its lowest after daily cases peaked at more than 900 in late February, according to KCDC, adding the total stood at 10,450 cases. The death toll rose by seven to 211, it said. The city of Daegu, which endured the first large coronavirus outbreak outside of China, reported zero new cases for the first time since late February. With at least 6,807 confirmed cases, Daegu accounts for more than half of all South Korea’s total infections. The spread of infections at a church in Daegu drove a spike in cases in South Korea beginning in late February. The outbreak initially pushed the tally of confirmed cases much higher than anywhere else outside of China, before the country used widespread testing and social distancing measures to bring the numbers down. Claim: South Korea reports recovered coronavirus patients testing positive again.

SOLUTION:
South Korean officials on Friday reported 91 patients thought cleared of the new coronavirus had tested positive again.
