TAMPA, Fla. — Air conditioning units may be contributing to the spread of COVID-19, especially in the southern part of the United States, according to a Harvard epidemiologist.Dr. Edward Nardell is a professor in the Departments of Environmental Health and Immunology and Infectious Diseases at the Harvard T.H. Chan School of Public Health. He's done in-depth research on how air conditioning units contribute to the spread of airborne infections.Nardell said air conditioning can help airborne viruses spread in three ways.First, people go inside to cool down, when you are much safer outdoors, Nardell said. Now, we're seeing more people indoors because of the high heat and humidity, specifically in the southern states like Florida.The second problem is that air conditioning brings in very little outside air, according to Nardell. While this isn't a major problem inside your own home, it can be especially problematic in corporate settings."It just isn't economically possible to bring in outside air, recirculate it and dehumidify it," he said.Lastly, he said when people are indoors, you're often not spaced out safely as you would be outdoors."You are not socially distanced as much, but you're re-breathing the same air that someone else just exhaled," Nardell said. "We call it rebreathed air fraction, and if someone is infectious, often asymptomatic, you're going to be rebreathing their small particles."Nardell also said air conditioning units can generate air currents that can carry large particles even further, similar to what researchers found contributed to the spread of the novel coronavirus disease in an air-conditioned restaurant in Guangzhou, China, involving three family clusters.On the Department of Homeland Security's website, this tool can be used to estimate how long the virus would be expected to remain stable while airborne.Now, the Centers for Disease Control and Prevention is recommending restaurants increasing the distance between tables and improving ventilation.The use of germicidal lamps, a technology that Nardell said is almost 100 years old, has been proven effective in protecting against tuberculosis infection and is already in use in some settings to fight COVID-19.The lamps are set up to shine horizontally, high in the room where sterilization is needed. Air currents, stirred in part by warmth from human bodies, circulate up to the ceiling, where the ultraviolet light kills floating pathogens, and then back down again.This technology, Nardell said, is not only proven, but it can also be deployed cheaply and easily in a number of settings as society reopens.This story was originally published by Lauren Rozyla at WFTS. 2691

TALLAHASSEE, Fla. — The Florida Education Association announced a lawsuit against the state's emergency order that forces districts to physically reopen public schools five days a week in August, despite concerns from parents and educators regarding the spread of COVID-19.The lawsuit was filed Monday in state circuit court in Miami against Gov. DeSantis, Florida Education Commissioner Richard Corcoran, the Florida Board of Education and Miami-Dade mayor Carlos Gimenez.The lawsuit contends that ordering a return to on-site instruction at public schools is a violation of Florida’s Constitution and requests a declaration that the state defendants’ actions and inactions are unconstitutional.The suit also seeks a declaration from the court that the state's demands are "arbitrary and capricious" and seeks to prohibit the enforcement of the order.RELATED: Florida education commissioner calls school reopen lawsuit 'frivolous'The FEA contends the mandate does not allow districts enough time for effective planning, even when it comes to offering distance-learning options."As many districts were preparing to implement hybrid education models and online instruction initiatives, just weeks before the start of the school calendar, they now find themselves forced to crowd millions of students into schools where physical distancing, although critical, becomes virtually impossible," the lawsuit reads.View Lawsuit BelowThe state's largest teachers union also launched a petition to Gov. Ron DeSantis that says the state's students must not return to school campuses until steps are taken to reduce the rate of community spread of COVID-19."The rate of infection is growing at an alarming pace, yet little is being done to slow the spread and even less is being done to support a SAFE return to our schools," the FEA posted on their Facebook page. "We must demand our governor take all necessary steps to slow the infection rate in our state before our children return to brick and mortar schools." 2011

TAMPA, Fla. — A creation to help combat the coronavirus from USF Health and Tampa General Hospital is now helping people across the world.When the COVID-19 pandemic started, researchers worked to fill in gaps from the shortages that came with it, including nasal testing swabs.“Unfortunately that component of the test kit was missing because it actually comes from overseas and actually it’s manufactured in northern Italy and if we recall back to March that is where everything was shut down and so that directly impacted our ability to be able to start testing for COVID in the U.S.,” said Summer Decker, Ph.D., the director of 3D clinical applications at USF radiology and TGH.So a team used technology in their lab to create a 3D nasal swab.“We worked with our colleagues here and the department of infectious disease and emergency medicine to be able to come up with an alternative to that swab that was in the test kit that actually was patient safe, comfortable and actually was able to capture that viral test that we needed so badly to do,” said Decker.Quickly, they moved from design to clinical research, partnering with Northwell Health in addition to TGH.“So suddenly we were getting bags and bags of these test kits thousands a week and it’s what saved us and I think in some ways it saved the Tampa Bay area because it allowed our hospital to really keep up this high volume testing,” said Dr. Jason Wilson, the associate medical director of TGH’s emergency department.That clinical trial is now completed.“What we found was pretty amazing. They performed as well and in some cases even better than the traditional swab,” Decker said. “That clinical trial has now come out it’s been published in a top journal for infectious disease.”Wilson said the hospital still uses them when there’s not enough standard of care swabs.The team also shared the information with the swab for other hospitals and agencies facing shortages, so they could create them. Since then, Decker said tens of millions are being used in more than two dozen countries.“It’s pretty incredible to us. We all kind of keep pinching ourselves,” Decker said.She says to her, the swab represents collaboration.“It’s not just a COVID thing. This is something that we can look at using long-term and beyond this COVID situation,” she said.This story was first published by Haley Bull at WFTS in Tampa Bay, Florida. 2401

Survivors of last month's deadly school shooting in Parkland, Florida, are preparing to take their fight for stricter gun control laws to Washington.This week's March for Our Lives is the culmination of a monthlong effort to honor the 17 students and faculty members killed at Marjory Stoneman Douglas High School, and rally Americans across the United States to say enough to gun violence.With momentum from the National School Walkout still going strong, students are demanding that their voices be heard. 515
