The American Red Cross is now checking all blood donations for coronavirus antibodies, instead of just searching for recovered patients. The organization is calling it a “game changer.”“We can then not only inform that donor of the testing results that we've identified COVID-19 antibodies in their blood, but also use that product as convalescent plasma to help patients who are ill with COVID-19 in the hospital,” said Dr. Pampee Young, Chief Medical Officer at the American Red Cross.Early results from the National Institutes for Health show the plasma can make a big difference for severely sick COVID-19 patients. And data from these new tests will help those researchers working to better understand the virus.The Red Cross says the need for whole blood donors is constant, but plasma is more unpredictable.Over the summer, plasma supplies ran low after unprecedented infections and demand in some states.Now, they're asking more donors to step up to restock for another potential surge in the fall and winter.“Because we can’t predict the demand, we want to ensure that we have enough inventory, because what really saves lives are the units that are on the shelf, not something that we need to collect once we realize there’s a need,” said Young.The Red Cross has taken additional safety steps during the pandemic. That includes making an appointment.You can sign up online at RedCrossBlood.org or by using the blood donor app. 1444

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 — Wearing masks is one of the most important ways to prevent the spread of COVID-19 — and health experts say everyone should continue to care for their face coverings to ensure protection when in public.After wearing a mask for a few months, doctors say there are some clear, tell-tale signs that it is no longer working correctly."When the edges start to fray or if the pieces where they connect start to fall apart, or if they are visibly soiled, then you should really get a new mask," said Dr. Tracey Taylor, the associate dean of USF College of Nursing.Experts also say that if a mask no longer fits over the nose or doesn't have a close fit around the face or chin, it's time to get a new one."It's super important to make sure your mask is fitting appropriately, that it's not visibly soiled, that the edges aren't frayed and that the attachments to the ear loops or tie backs — whatever type you're wearing — is appropriately attached," Taylor said.For those who own cloth masks, experts say owners need to remember to wash them. Experts say washing cloth mask with detergent or soap is best and that they don't need to be washed with super hot water. Those who own cloth masks with filters should remove the filter and clean it separately.However, there's another option."You can put them in a paper bag and seal it up for a couple of days. That'll inactivate any virus that's on it," said Dr. Marissa Levine, a professor of public health practice at USF.After several months, experts say they have more information about which masks are effective in preventing the spread of COVID-19.Cloth masks are most effective when they have at least three layers of material or a spot to add a filter. They're typically the easiest for the general public to use because they're reusable, and doctors say the research shows they mostly prevent the spread of the virus.Although any face covering is better than none, some aren't as effective in preventing the spread of COVID-19.Experts say bandanas are very thin and don't offer the same type of protection as a mask.Doctors say any mask with a valve on it is completely ineffective because the valve allows virus-carrying particles to leak out.Popular neck gaiters that wearers can easily pull up and down don't provide a lot of protection for the wearer or those around them."If you find yourself with a single layer, you could use something like a paper towel inside there to add an extra layer if you need to," Levine said.Experts advise keeping two masks on hand in case one gets lost or breaks."There's no one thing that we do that will protect us to the highest level. It's a series of things," Levine said.This story was originally published by Larissa Scott on WFTS in Tampa, Florida. 2755
