A woman in Oklahoma is warning people to stay home and isolate if they feel sick, even if they have a negative COVID-19 test. "Don't trust a negative COVID test. If you have the symptoms, especially that loss of taste and smell, you have to stay home,” Lesley Shollmier told local media.Shollmier should know, she had three negative tests before a fourth one came back positive.A few days before Thanksgiving, she started feeling sick, so she took a PCR test and it came back negative. Then a day or two later, she felt more sick and fatigued, and had a rapid COVID-19 test to be sure she was negative before spending Thanksgiving with family. That test also came back negative.Her and her husband had a small Thanksgiving with her mother, brother and sister-in-law.The day after Thanksgiving, Shollmier tells CNN she made a cup of tea and slice of pumpkin pie, when she realized she couldn’t taste or smell."I immediately knew, this is COVID. I just knew that that was one of the classic symptoms and regardless of anything, I have to have it. As odd as it sounds, I was fortunate to have that symptom so that I knew for sure that I was doing the right thing,” Shollmier told KTUL.She went to a different testing site and took a PCR test. The next day, those results came back negative.Her symptoms got worse, congestion moved into her chest, so she self-quarantined in her home keeping away from her husband on the second floor.She took another PCR test for COVID-19 on November 30, and again, results came back negative.She continued to isolate as symptoms got worse, now including back aches, shortness of breath, congestion and fatigue."I just assumed 100% I had COVID-19 and the last thing I wanted to do was infect someone,” Shollmier said.On December 2, she reached out to her doctor and asked to take a fourth PCR test.Finally, after having symptoms for 12 days, Shollmier finally had a positive COVID-19 test result.The FDA says molecular tests, like the PCR test, look for the virus’ genetic material and most are done with nasal swabs or throat swabs, and are typically highly accurate.Health experts agree with Shollmier’s decision to isolate even without a positive test result. A study published in August showed that people who took a test on the day they started showing symptoms had a false-negative rate of 38%. Even three days later, those who had COVID-19 with symptoms still had a false-negative test rate of 20%.After Thanksgiving, the White House coronavirus task force urged Americans who traveled for the holiday to assume they were likely infected and to isolate on their own. Shollmier is sharing her story as a warning to others."Listen to your gut. Know when you're sick and when you need to stay home. And just because you get that negative test doesn't mean that you're negative,” Shollmier told KTUL.She is still dealing with lingering symptoms. She tells CNN her family has been tested twice so far, and no one has symptoms or has tested positive. 2989

After eight months of steady gains, stock market volatility has again rocked investors this week, with a global sell-off triggered by the prospect of slower global economic growth and rising bond yields. The S&P 500 fell nearly 7% in six days, bringing the index down to levels last seen in July.When stock markets tremble, the advice from financial advisors is simple: Stick to your investment plan.That’s easier said than done. If your financial house is on fire, you want to fight the flames or flee as surely as if your actual home were ablaze, behavioral finance experts say. To stand back, watch and periodically throw more money on the bonfire is tough even for the most seasoned investor, let alone your average 401(k) holder.“You’d think that a high-net-worth individual is more sophisticated, that they are not going to panic like an investor with ,000 at stake? Not true,” says David Thomas Jr., founder and chief executive officer of Equitas Capital Advisors in New Orleans.Still, Thomas says, “You can be smarter than your emotions, but that’s an acquired skill.”Here are some ways to sidestep the natural emotional triggers that can be costly during the next market correction or crash. 1220

After months of protests, sometimes becoming violent, Portland Mayor Ted Wheeler announced Thursday that the city is banning the use of tear gas by his city’s police.Wheeler said everyone has an obligation to create change, and now is the time to change the city’s policy on using tear gas.“During the last hundred days Portland, Multnomah County and State Police have all relied on CS gas where there is a threat to life safety,” Wheeler said. “We need something different. We need it now.“Arson, vandalism, and violence are not going to drive change in this community. I expect the police to arrest people who engage in criminal acts. I expect the District Attorney to prosecute those who commit criminal acts. And I expect the rest of the criminal justice system to hold those individuals accountable. We must stand together as a community against violence and for progress.”The issue of using tear gas amid protests has become a legal battle, as demonstrators say that the use of tear gas to disperse a crowd violates their constitutional rights. In June, U.S. District Judge March Hernandez ruled that the use of tear gas on protesters in Portland could only be used when lives are at risk.The police responded on Thursday by saying gas is a tool needed by officers to control crowds when protests become violent.“Banning the lawful use of CS will make it very difficult to address this kind of violence without resorting to much higher levels of physical force, with a correspondingly elevated risk of serious injury to members of the public and officers,” the Portland Police said in a statement. “CS, while effective, is a significantly lower level of force than impact weapons, which would very likely be necessary to disperse riotous groups with its prohibition. We do not want to use gas. We do not want to use any force.”As to why tear gas is used instead of police going in to make an arrest?“To make an arrest in the middle of a crowd intent on destruction and injuring people, it takes considerable resources--large numbers of officers that we do not have,” the police said. “Not only do we not have enough PPB officers to respond in this manner, our area partners have stated they will not come to our aid, given the climate in Portland.”The city’s downtown has dealt with protests and unrest since Memorial Day following the death of George Floyd in Minneapolis. Adding to the challenges for law enforcement in recent weeks, counter-protesters have arrived and clashed with Black Lives Matter supporters.The unrest culminated on August 29 when Aaron Danielson was shot and killed. The suspect in the case, Michael Forest Reinoehl, was later killed by US Marshals in Olympia, Washington. The US Department of Justice claimed that Reinoehl was a supporter of ANTIFA. The Associated Press reported that Danielson joined the counter-protest as part of a group known as Patriot Prayer, which aligns itself with President Donald Trump and that allegedly shot paintballs at protesters in Portland. 3015

After spending 23 years in prison for a crime he did not commit, Nevest Coleman is back at work with the Chicago White Sox.Coleman, then a 25-year-old groundskeeper with the White Sox, was convicted of the 1994 rape and murder of a Chicago woman and sentenced to life in prison without parole.He was freed last year after DNA found on the victim was linked to a serial rapist.Friends and family contacted the White Sox after his release to help him get his old job back, CNN affiliate WGN reported.The team said it was grateful that "justice has been carried out for Nevest" and said they were happy to welcome him back to the team as one of its groundskeepers.Coleman told WGN that he watched Sox games while he was in prison and would see his former colleagues scramble to protect the field during rain delays.Two of his friends who are still on the grounds crew were there to greet him with big hugs on Monday morning when he arrived for his first day back on the job.He was issued a new uniform and hat. He then put on a big yellow rain suit to pressure wash the sidewalk and got to work.A lot has changed while Coleman was away. The stadium has had extensive renovations and is now known as Guaranteed Rate Field instead of Comiskey Park.One thing, however, has remained constant for Coleman."I was in a situation where I felt comfortable here and everybody here was family to me," he told WGN.  1413
