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

DETROIT — The Trump campaign announced Thursday it was dropping its lawsuit over the election results in Michigan. The news comes as two Republicans try to rescind their vote that certified Wayne County's election results, however there is no "legal mechanism" for them to do so.According to a statement from Trump lawyer Rudy Giuliani, the campaign wanted to stop the Wayne County results from being prematurely certified.“This morning we are withdrawing our lawsuit in Michigan as a direct result of achieving the relief we sought: to stop the election in Wayne County from being prematurely certified before residents can be assured that every legal vote has been counted and every illegal vote has not been counted," Giuliani said in a statement.It is also being reported that President Donald Trump reached out to the two Republican members of the Board of Canvassers in Wayne County before they sought to rescind their votes.The two Republican members initially voted against certification Tuesday night, then reversed course and voted for certification just ahead of the deadline. Now they are trying to rescind those votes."There is no legal mechanism for them to rescind their vote. Their job is done and the next step in the process is for the Board of State Canvassers to meet and certify," said a statement from Michigan's Secretary of State Jocelyn Benson.Monica Palmer, chair of the Wayne County Board of Canvassers, and William Hartmann, one of two Republicans on the Board, filed signed affidavits Wednesday night demanding to rescind their "yes" certification votes."I fully believe the Wayne County vote should not be verified," Palmer said in an affidavit. "The Wayne County election had serious process flaws which deserve investigation. I continue to ask for information to assure Wayne County voters that these elections were conducted fairly and accurately."After the two Republican members of the Wayne County Board of Canvassers initially caused a deadlock Tuesday, they eventually agreed to certify the county's vote on the condition of an audit.The motion to hold another vote came following hours of public comments condemning Republican canvassers' decisions to vote against the certification."Late in the evening, I was enticed to agree to certify based on the promise that a full and independent audit would take place," Palmer wrote. "I would not have agreed to the certification but for the promise of an audit."Both Palmer and Hartmann claim they were pressured into agreeing to certify the results after being subjected to harsh comments during a lengthy public hearing."This vote was followed by public derision from our two democrat colleagues. I, and Monica Palmer, who also voted against certification, were berated and ridiculed by members of the public and other Board members," Hartman state in the affidavit. "This conduct included specious claims that I was racially motivated in my decision. This public ostracism continued for hours during which time we were not provided an opportunity to break for dinner and were not advised that we could depart and resume the hearing on another date."The first vote tied 2 to 2 along party lines. But just before 9:30 p.m. Tuesday, the Board filed a motion and voted to certify the results under the stipulation that Secretary of State Jocelyn Benson does a comprehensive audit of the election in the county.The canvassers' initial vote came after many Detroit precincts were found to be out of balance — meaning the number of votes is not in line with the number of voters. However, the variance is said to be small, with no evidence of fraud or systemic failure.President Donald Trump, who has continually made unsubstantiated claims about widespread voter fraud, has criticized the Board's decision to certify the election.All 83 counties in Michigan have voted to certify the results of the Nov. 3 election, according to Michigan Secretary of State Jocelyn Benson.The Board of State Canvassers is set to meet Monday — in a hearing that is open to the public — to certify the total number of votes cast in the November general election.In December, all of Michigan's electors are expected to cast their votes for Joe Biden, who won the state by over 150,000 votes.View the affidavits below:Palmer Affidavit by WXYZ-TV Channel 7 Detroit on ScribdHartmann Affidavit by WXYZ-TV Channel 7 Detroit on ScribdThis story was originally published by Fatima Bangura and Max White on WXYZ in Detroit. 4484

DALLAS (AP) — The Texas Supreme Court has denied a Republican-led petition to toss nearly 127,000 ballots cast at drive-thru voting places in the Houston area. The state's all-Republican high court on Sunday rejected the request from GOP activists and candidates without explaining its decision. The effort to have the Harris County ballots thrown out is still set to be taken up during an emergency hearing in federal court on Monday. Conservative Texas activists have railed against expanded voting access in Harris County, where a record 1.4 million early votes have already been cast. 596

DENVER, Colo. - Air traffic in and out of Denver International Airport was impacted Tuesday afternoon following COVID-19-related cleaning procedures at an FAA facility on airport grounds, a DIA spokesperson confirmed to Denver7.DIA said they were in a ground stop for only a few minutes around 3:30 p.m. Tuesday. The airport was on a ground delay or traffic management up until 6 p.m., delaying inbound traffic.The stop happened due to COVID-19-related cleaning in an FAA facility on airport property after an FAA employee tested positive for the virus. Air controllers were moved into a backup room to clean the main room. Officials said the cleaning did not happen at the airport terminals or at the control tower.A DIA spokesperson estimated that nearly 200 planes were delayed and 45 were canceled during the transition.Denver7 spoke with a mother who says her son was pulled off his plane and told there would be a delay due to weather.“We all understand what happens with COVID and the shutdowns and everything, but it’s less scary knowing that’s what it was as opposed to trying to figure out, well why is the shutting down the airport and not telling us why?" said Kelly Suchey.She says DIA AND the FAA should have been more transparent about what was going on.So Far, four FAA employees have tested positive for COVID-19.This story was first reported by Robert Garrison KMGH in Denver, Colorado. 1412
