It’s been four months since most of the nation’s schools abruptly shut down because of the COVID-19 pandemic. Now, schools are considering reopening, while COVID-19 cases continue to rise. So what’s changed that supposedly makes a return to campus safe?“Occasionally you have schools close because there's an outbreak of measles or flu or something like that, but not to this scale,” Dr. Elizabeth Hinde, Dean of the School of Education at Metropolitan State University of Denver, said.Districts are scrambling to figure out how to return to school this fall as COVID-19 continues to spread across the U.S.Back in March, almost every school was forced to close, a mindset much different than today's.So what has changed? We sat down with a global health affairs professor, an education expert, and an infectious disease doctor to look at the changes between now and four months ago.Within the span of a week, states told their schools to shut down.“When everything closed down in March, we were comforting a new disease, we were terrified at what it could do,” Dr. Sandy Johnson, director of the global health affairs program at the University of Denver, said.Little was known about COVID-19.“School closures are always a part of the mitigation strategy along with quarantine, stay at home orders, etcetera,” Dr. John Hammer, an infectious disease specialist at Rose Medical Center, said. “The difference between March and now is that we have a better sense of how the virus works. How it’s transmitted.”There’s more to this decision than a better understanding of the virus.“When we’re talking about whether or not schools should open, another factor is the loss in achievement and also there are equity issues that have really come to the fore” Dr. Hinde said.Kids finished the school year from home -- some didn't have the proper tools or the support of a school, opening the door for inequity.“We know that there are mental health issues,” Dr. Johnson said. “Our front line social workers that are looking for domestic violence and we know domestic violence has been going up. So there are many important roles in addition to education that come in those schools.” This also includes food and housing insecurity.Another factor in consideration -- teacher health.“These folks are balancing fear. Fear for their health, fear for the health of their families, with this real desire. They understand how important education is,” Dr. Johnson said.“There's just no definitive answers that principals and superintendents and teachers can lean on,” Dr. Hinde said.What was a state decision in the spring has now been put on the shoulders of school districts, as they weigh the pros and cons of returning to in-person learning.“Every school board, every school district, has to make a very tough decision. It is a very delicate balancing act,” Dr. Hammer said.“Local control is a strength in American schools, but it does make decision making very complex, because the superintendents of schools and principals are listening to all these different voices,” Dr. Hinde said.From teacher health and safety, to inequities in learning and the mental health of children, school leaders have a lot of elements to look at when it comes to opening classroom doors.“I think in the next couple weeks we’ll see decisions made,” Dr. Hinde said. “All of this, it’s a new world.” 3367

In most states, it is illegal to sell or give tobacco products to someone who is 18 years old or younger.But many are increasing the legal age to 21 years old.Cincinnati, Ohio just became the 16th city in that state to do so. The state's minimum age is 18. (There is no minimum age at which someone in Ohio may legally use tobacco products.)Minimum ages for purchasing tobacco have been set at the state level dating all the way back to the late 1800s.Increasing the legal age is an effort to reduce habitual smoking among young people.The Centers for Disease Control and Prevention says most long-term tobacco use begins when a smoker is an adolescent, and nearly 90 percent of smokers have their first cigarette by age 18. 742

INDIANAPOLIS -- A Bloomington, Indiana auto dealership was told to stop selling cars after the Indiana Secretary of State's Office discovered the business is not licensed in the state. The secretary of state's office issued a cease and desist Friday to H Auto for selling cars without a license and illegally issuing interim license plates.H Auto has been advertising in English and Chinese and allegedly may have been targeting Chinese students at Indiana University, according to the secretary of state. The advertisements say to make an appointment because H Auto does business by appointment only, but typically most dealerships do walk-in business.Some customers of H Auto allege that they were sold cars with fake New Jersey license plates.Others allege the auto dealer took their money but they never got a title for the vehicle they purchased.The secretary of state's office and Bloomington police are currently investigating.If you believe you may have been victimized by H Auto, call the secretary of state's office at 317-234-7190 1074

  

It is possible that after the election, neither President Donald Trump nor former Vice President Joe Biden have enough Electoral College votes to be president. A 269-269 tie is unlikely, but possible under different scenarios, including the one mentioned below 269

  

It’s a move the surgeon general hasn’t taken in thirteen years — issue an official advisory. The last time was in 2005, and it concerned pregnant women and alcohol. But on Thursday, Surgeon General Dr. Jerome Adams announced a new advisory regarding Naloxone, the drug that combats an opioid overdose and encouraged more people to carry it with them for themselves or others. According to the Surgeon General’s release, “Knowing how to use naloxone and keeping it within reach can save a life.”And administering Naloxone — Narcan is the most common name brand — is actually relatively simple, doctors say.Aaron Wolfe is an emergency room doctor at Presbyterian/St. Lukes Medical Center in Denver and likens it to using an Epi-pen for allergic reactions — except this is even easier.“You don’t even have to worry about needles or somebody being stuck,” Wolfe said.“When people are close to death from opioids it usually stops their breathing, so this drug will reverse that,” Wolfe added. “It’ll make them be able to breathe again regain full consciousness.”All you have to do is spray the drug into a person’s nostril. They do not have to inhale.Most pharmacies carry the drug. In 46 states, you don’t even need a prescription to obtain it. If you have insurance, it’s usually covered, but if you don’t it’ll cost around 0 to 0. 1357
