WASHINGTON — Hiring jumped in February as employers added 273,000 jobs, evidence that the economy was in strong shape before the coronavirus began to sweep through the U.S. The Labor Department said Friday that the unemployment rate fell to 3.5%, matching a 50-year low, down from 3.6% in the previous month. The job gain comes from a survey of payrolls in the second week of February, so the healthy gains pre-date the viral outbreak. 447

Wednesday’s Democratic Party presidential debate hosted by NBC News could make for one of the most intriguing debates in recent memory. The late entry of Michael Bloomberg has posed an intriguing case study on whether it’s possible not to participate in the early-state nominating contests and still earn the nomination.So far, Bloomberg has spent hundreds of millions in advertising. While commercials help spread a candidate’s message, advertisements do not face the type of scrutiny a stage full of opponents questioned by moderators does. And with Bloomberg’s recent rise in the polls, he could be facing incoming from everyone on the stage.When: Wednesday, Feb. 19, 9-11 p.m. ETHow to watch: NBC, MSNBC, NBCNews.com, Universo (Spanish Translation)The candidatesFormer Vice President Joe BidenFormer New York City Mayor Michael BloombergFormer South Bend, Indiana Mayor Pete ButtigiegMinnesota Sen. Amy KlobucharVermont Sen. Bernie SandersMassachusetts Sen. Elizabeth WarrenFive of the six candidates have participated in every previous debate. QualificationsCandidate earned at least 10% support in four national polls, or 12 percent in two Nevada and/or South Carolina polls, or have at least one national delegate pledged from the Iowa or New Hampshire primaries. Wednesday’s debate marks the first debate that has lifted the requirement to meet fundraising thresholds. This is what allowed Bloomberg to enter the debate. Ridding the fundraising requirement for Bloomberg, who has largely self-funded his campaign, did not please Warren. “It’s a shame Mike Bloomberg can buy his way into the debate,” Warren said. “But at least now primary voters curious about how each candidate will take on Donald Trump can get a live demonstration of how we each take on an egomaniac billionaire.”Who isn’t on the stageBillionaire Tom Steyer will not participate in a debate for the first time during the 2020 cycle. This comes despite strong polling numbers in Nevada and South Carolina. Also, Rep. Tulsi Gabbard, who last participated in a debate in October, did not qualify. Businessman Andrew Yang has dropped out of the race since the last debate. Other candidates who have since dropped out include Sen. Michael Bennet and Gov. Deval Patrick. Where the race standsButtigieg holds a slight lead in delegates over Sanders (23-21). Other candidates with delegates are Warren (8), Klobuchar (7) and Biden (6). Bloomberg did not enter the first two nominating contests, and will sit out Saturday’s Nevada Caucuses and the South Carolina Primary on Feb. 29. Although Buttigieg holds the lead in delegates, it is hard to describe him as the frontrunner. Sanders has a plurality of votes, and leads national polling. Real Clear Politics tracks major opinion polls, and an aggregate of polls show that Sanders has seen his share of the vote go from 19% to 27% in the last three weeks. During that time, Bloomberg has seen his numbers more than double, as he has gone from the back of the pack to nearly even with one-time frontrunner Biden for second. Sanders also is polling well in Nevada, a state he won in 2016. An East Carolina University poll held this week shows Biden still holds a lead in South Carolina, despite poor performances in Iowa and New Hampshire. But on March 3, the biggest night of the nominating race awaits as more than a dozen states, including Texas and California, hold primaries. These states are already conducting early voting, meaning Wednesday’s debate could be the final opportunity for candidates to make an impression before a crucial Super Tuesday race. Debate rulesThe moderators will be "NBC Nightly News" and "Dateline NBC" anchor Lester Holt, "Meet the Press" moderator and NBC News Political Director Chuck Todd, NBC News Chief White House Correspondent and host of "MSNBC Live" Hallie Jackson, Noticias Telemundo Senior Correspondent Vanessa Hauc and Jon Ralston of The Nevada Independent.Candidates will have 1 minute and 15 seconds for answers and 45 seconds for follow-ups at the moderators’ discretion, NBC News said.Race issues facing Bloomberg, candidatesGiven that Wednesday is the ninth debate since the start of the nominating process, it is very possible that many of the question will be directed at Bloomberg. How he responds to issues such as “Stop and Frisk” and race relations more broadly could be seen as key. Bloomberg will likely be asked about why he allowed “Stop and Frisk,” a policy that allowed NYPD officers to stop citizens to conduct pat downs without probably cause, to exist for years. Opponents of stop and frisk claim that blacks were targeted by the policy, and that these stops did not reduce crime. Proponents said that stops of these nature are permissible by Supreme Court ruling, and dispute findings that the stops don’t reduce crime.Buttigieg and Klobuchar could also be probed on race relations, especially since both candidates did well following the New Hampshire primary. Buttigieg has faced criticism over housing and policing policies while mayor. Meanwhile, Klobuchar has been facing questions on her prosecution of Myon Burrell, who was convicted of killing an 11-year-old girl with a stray bullet. The AP reported that no guns, fingerprints or DNA tying Burrell to the homicide were ever found.Black Democratic voters make up nearly 20% of the party’s electorate. 5358

Two rural town school districts in the United States were shut down early for the Thanksgiving holiday weekend due to a fast-spreading stomach virus causing an abnormally high number of absences.Mesa County Valley School District officials in Grand Junction, Colorado, closed the school district to decontaminate November 20, the Wednesday before the week of Thanksgiving. A high number of students were increasingly calling out sick due to an illness going around. “Before the school district shut down, we were aware of at least 13 schools within (Mesa County Valley) School District 51 that had increased absenteeism levels due to illness and that number was growing,” district officials said on a Facebook live video, addressing the problem. “What we’re suspecting at this time is it’s very much acting like a norovirus.”On November 25, Greater Albany Public Schools in Albany, Oregon, announced a district-wide closure for similar reasons — norovirus was going around causing high levels of absences.“It spreads really like wildfire through a community,” said Dr. Chris Nyquist, the medical director of infection prevention and control at Children’s Hospital Colorado. “I think norovirus is one of those viruses that comes up in wintertime often when you have small communities, thinking about schools, where a lot of kids are together. It’s very contagious, spreads quickly.”Norovirus symptoms include vomiting, diarrhea and nausea that can last days.“The best method that these schools have done, in conjunction with talking to their health department, is to really shut down and do extensive cleaning,” Nyquist said.Norovirus can transfer easily through close contact, and symptoms start as soon as two hours later. In small communities like Grand Junction or Albany, an outbreak like this can have a large impact.“The thing that’s really special and unique about rural Colorado is that schools are often time the hub of the community,” said Elaine Belansky, the executive director for the Center for Rural Health and Education at the University of Denver. “They don’t have that many boots on the ground to address big challenges like this.”But those communities are doing what they can to stop illness from spreading just as the holidays begin. Mesa County Valley School District posted a video of the decontamination process in one of their classrooms to Facebook to show the efforts being done.As for prevention, Nyquist said the best thing to do is to wash your hands with soap and water. 2512
