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

TAMPA, Fla. — University of South Florida Professor Dr. Jay Wolfson and health experts around the world are studying the latest research project on the coronavirus."This thing gives us surprises almost every week. We learn something new, and it's usually unpleasant every week," said Wolfson.The new research is from Australia's National Science Agency, and it found the virus could survive and remain infectious on surfaces like glass, steel, and paper for up to 28 days."What they are concerned about, what we are all concerned about it, is if you have some viable virus on your fingers and you touch your eyes or you touch your nose or you touch your friend's eyes or nose, there's a greater risk of it being brought into the body if there's enough of it there," said Wolfson.But Dr. Thomas Unnasch, also with USF Health, says this study was done with perfect conditions for a virus to thrive."They put the virus under different surfaces and then preserve them in the dark at ideal temperatures and humidity. So it's not too surprising that under those ideal conditions, that it would last quite a bit longer than it would under normal conditions."While experts agree COVID-19 primarily spreads from person to person through droplets in the air, there is still more to understand about how it can transfer from objects or surfaces to people."People do have a proclivity to touch their face and their eyes, so if you are in a place that's not familiar to you and you are using things that are unfamiliar to you, just be careful," said Wolfson."Your own cell phone, if you are the only one using it, that's not a big deal. But door handles, faucet handles elevator buttons things like that. Wash your hands after you do that. That's a really good idea," said Unnasch.All of the experiments in this study were done in the dark. Research has shown direct sunlight can kill the virus.This story was first reported by Erik Waxler at WFTS in Tampa Bay, Florida. 1965
