Decades of underinvestment has left tens of thousands of schools across the country with inadequate ventilation systems, a problem that is now front and center in the debate to reopen schools during the pandemic.Nationally, 90 percent of schools fail to meet minimum ventilation standards. It’s an issue Dr. Joseph Allen has been sounding the alarm about since COVID-19 first shut down schools earlier this year.“We’ve chronically underinvested in our schools’ buildings,” said Dr. Allen who serves as the director of the Healthy Buildings program at the Harvard Chan School of Public Health.Dr. Allen and his colleagues have spent months analyzing school buildings, and back in June, they released a detailed 60-page report that school districts could follow in order to safely bring kids back into the classroom.In order to keep COVID-19 from spreading in schools, two things have to happen: everyone in the buildings must be wearing masks and school districts need to ensure buildings have proper ventilation, the report found.“If air is being recirculated and not filtered, all of that air that’s coming from one space and going to another could be potentially contaminated and spread the virus,” Dr. Allen said.But replacing decades-old ventilation systems that may not work properly is expensive and time-consuming. Because of that, Dr. Allen is recommending school districts also consider portable air cleaners for classrooms.Through his research, Dr. Allen found that if you can change the air in a classroom five times per hour, it cleans the air in that space every 12 minutes. However, the air cleaners must be equipped with a HEPPA filter in order to be effective.Even something as simple as opening windows could reduce the transmission of the virus.“If you look at the cases of spread in school right now, they all share common traits; it’s no mask-wearing and low to no ventilation. When we do that, we can guarantee there will be more cases,” he explained.Last week, the Healthy Buildings program also released a detailed portable air cleaner calculator. The tool allows school administrators to input the size of the classroom, even ceiling height, and then determine the kind of air cleaner that would most effectively keep COVID-19 from spreading.“It is critically important that we get kids back into in-person learning and we haven’t treated it as this national priority that it needs to be,” Dr. Allen added. 2438

DENVER -- A federal judge has temporarily stopped the U.S. Postal Service from sending pre-election fliers with information about mail-in voting, after Colorado's Secretary of State filed a lawsuit claiming the fliers contain "misleading" and "incorrect" information for her state's voters. The USPS is appealing the decision Monday morning. “The mailer incorrectly asks that voters request a mail ballot 15 days before the election and return their ballots by mail at least seven days before the election. In Colorado, every registered voter is sent a ballot without having to make a request and voters are urged to return ballots by mail sooner than seven days before the election,” Secretary of State Jena Griswold wrote in a statement released Saturday.The lawsuit was filed late last week, and Saturday evening Griswold tweeted that a judge had granted Colorado a temporary restraining order, preventing the postal service from sending out the mailer to Colorado voters.The restraining order will stay in place until September 22 unless changed by the court. James Boxrud, a USPS spokesperson, said in a statement that the postcard is part of a non-partisan campaign that the agency launched to educate the public on the upcoming election.“The non-partisan campaign neither encourages nor discourages mail-in voting; rather, it is designed to reach and inform all voters about the importance of planning ahead if they plan to vote by mail,” Boxrud said in a statement. 1481

DENVER — A passenger’s vaping device is being blamed for a fire that disrupted operations at Denver International Airport last month.According to a Friday release from the Denver Fire Department, the dissembled device was inside the passenger’s travel bag when it caught fire as it passed through a TSA X-ray machine in the south checkpoint the evening of Jan. 30.The screening process was not a contributing factor in the fire, the release said.Airport officials released surveillance video of the incident Friday. The video, viewable above, shows a crowded security line just before the fire sent hundreds of passengers and TSA agents running.The fire was quickly put out by using a nearby portable fire extinguisher. However, the incident prompted DIA officials to temporally halt train service and security screening, causing significant delays throughout the airport.Fire investigators say the device’s exposed lithium-ion battery likely made contact with conductive materials in the bag, causing the battery to create a “dead short.” The short caused the battery to heat up combustible materials within the bag, leading to the fire.The fire was determined to be accidental, and no charges were filed.The FAA prohibits electronic cigarettes and vaping devices in checked bags, but the agency does allow the devices to be carried in a carry-on bag. However, many airlines have policies regarding the possession or use of these devices onboard aircraft. 1474

Democratic presidential nominee Joe Biden discussed coronavirus vaccines during an event Wednesday after being briefed by public health experts on the issue.During his speech, Biden said that while he trusts what scientists say about a potential vaccine, he doesn’t trust President Donald Trump.He mentioned what he called Trump’s “incompetence and dishonesty” surrounding the distribution of personal protective equipment and coronavirus testing. “We can’t afford to repeat those fiascos when it comes to a vaccine,” said the former vice president. “I trust vaccines, I trust scientists, but I don’t trust Donald Trump, and at this moment, the American people can’t, either.”The Trump campaign has accused Biden and his running mate, Kamala Harris, of sowing doubt about a potential vaccine by expressing concerns that politics count taint the approval process.Asked whether his comments could undermine public trust in scientists, Biden said the vaccine approval process should be “totally transparent” and it should be evaluated by a “board of scientists” that could give the public an unbiased opinion.Watch his remarks below:Biden's speech took place the same day that the federal government unveiled initial plans to distribute COVID-19 vaccines when they become available.According to a plan put forth by the Department of Defense and other federal agencies, the first round of vaccines would be reserved for medical professionals and essential workers. Eventually, vaccines would be distributed to whoever would like one.Vaccines would be provided to the public without cost thanks to Congress's legislation and signed into law by President Donald Trump.However, The Associated Press reports that officials face an uphill battle in getting the country vaccinated. A poll taken earlier this year indicates that about half of people would not take a vaccine if offered one.Biden's comments also come a day after President Donald Trump made the claim that COVID-19 would "disappear" even without a vaccine. 2019
