As scientists learn more about COVID-19, they are realizing that how people react to the virus could be based on the body's response to viruses like common colds.Meharry Medical College President Dr. James Hildreth says some studies are showing some individuals have T-cell responses to COVID-19 even though they never been exposed to it.He is talking about recent research revealing that some people may have immunity defenders called T-cells which could determine how their body reacts to COVID-19.According to the CDC, when the body fights an infection, the immune system remembers what it learned about how to protect the body against that disease.The body will retain a few specific T-cells known as memory cells - that will alert and help the immune system identify and produce antibodies to attack the foreign germ if it enters the body again."Viruses that look alike can sometimes elicit the same kinds of immune responses," said Hildreth.Hildreth says there are six strains of coronavirus that affect humans going back to the 1960s and some result in seasonal common colds.He says if you were infected with one of these viruses in the past it can determine the severity of the toll COVID-19 would take on your body now."There’s the possibility that a response to one of them gives you a partial to another because they have genetic similarities," said Hildreth.Hildreth says this doesn't mean a person has complete immunity to COVID-19."There’s strong evidence that you may not be immune to the virus, but you’ll have an immune response that recognizes SARS partially just because those two viruses look so much alike."Hildreth says this can help with treatments and even vaccinesThis story was originally reported by Kelsey Gibbs at WTVF. 1756

As more and more public spaces open back up, many people are finding themselves a little jumpy when they hear someone cough nearby. Are they sick, is it allergies, is it coronavirus?Chances are, we are jumping to conclusions about those “sick” sounds we find disgusting, according to a recently published study from the University of Michigan and University of California, Irvine.“We find no evidence that perceivers can reliably detect pathogen threats from cough and sneeze sounds, even though they are reasonably certain they can,” said Nicholas Michalak, the study’s lead author and a University of Michigan psychology graduate student.In other words, we humans are not very good at distinguishing the seriousness of a cough or sniffle by the sound of it. In fact, the study found that the more disgusting a person perceived the sound to be, the more likely they were to believe the sound came from an infected person, regardless of whether it did.Previous research has indicated people can accurately diagnose infection in others using other senses, like sight and smell.The research is based on four studies that had participants judge whether a cough or sneeze sound came from people infected with a communicable (easily spread) disease or not. On average, participants guessed four out of ten sounds correctly.“Moreover, there was no evidence that accuracy improved when participants knew the true number of infectious sounds in advance or when participants focused on how clear or disgusting they perceived the sounds,” Michalak said. “Despite this poor overall accuracy, perceivers consistently reported reasonable certainty in their judgments.”The study’s authors theorized that people have a belief that a sound that disgusts them is likely to represent a disease threat - this could lead them to exhibit biases to avoid interactions with others who make disgusting but noninfectious noises, according to Mickalak.The study’s co-authors are Oliver Sng, assistant professor of psychological science at UC-Irvine, and U-M graduate student Iris Wang and U-M associate professor of psychology Joshua Ackerman.Read the full study here. 2150

As millions of Americans have suddenly found themselves out of work due to the economic fallout from the novel coronavirus, many are also losing their health and dental insurance, creating what some doctors are calling a public health crisis.At Interfaith Dental in Nashville, Tennessee, patients Anna Eubanks waits patiently to have a new set of dentures fitted. The 68-year-old woman is one of an estimated 37 million people in the United States who does not have dental insurance."You think about it a lot, and just hope nothing ever goes wrong," she said while sitting in an exam chair with her mask on.Without insurance, a routine trip to the dentist would likely cost Eubanks hundreds of dollars, which is money she doesn't have. That is why she and her husband have turned to this non-profit dental clinic for help.Dr. Rhonda Switzer-Nadasi oversees Interfaith Dental, which is largely made up of dentists who volunteer their time so that people like Eubanks can get dental care at little or no cost. It’s a need more critical now than ever."There’s new groups of people that they were making it before and were right on that edge and are now struggling," Dr. Switzer-Nadasi explained.Since February, an estimated 12 million Americans have lost their healthcare coverage. Most lost their insurance when they lost their job.But the number of people without dental coverage is typically four or five times higher than the number of people without health insurance. This clinic that typically sees about 3,000 patients a year has seen call volume increase 20 percent."We are seeing a big increased need where people are suffering from job loss, where they may have had three jobs and they’re now down to one, or one down to none," she added.Nationwide, there's also a backlog for dental care. In this office alone, they were canceling 1,000 appointments a month during the shutdown. It’s something that worries Dr. Switzer-Nadasi during COVID-19, since most dentists are also checking a patient’s overall health. She's also seeing more patients put off emergency dental care because they're worried about cost."People that come see us don’t just need a check-up and cleaning,” she explained. “Most of the time, they’ve reached the end of their rope and what they need is critical.”But for now, this clinic and others like it across the country are doing their best to help whoever they can and preserve as many smiles as possible. 2442

Attorney General Jeff Sessions revealed Thursday that Utah's top federal prosecutor, John Huber, has been examining a cluster of Republican-driven accusations against the FBI and has decided that no second special counsel is needed -- at least for now.Huber has been looking into allegations that the FBI abused its powers in surveilling a former Trump campaign adviser, and more should have been done to investigate Hillary Clinton's ties to a Russian nuclear energy agency, but his identity had remained a secret.But Sessions' decision to stop short of formally appointing a special counsel like Robert Mueller, detailed in a lengthy written response to threeRepublican chairmen on Capitol Hill, will likely anger those in the GOP who have recently ramped up calls to investigate claims of political bias at the nation's top law enforcement agencies.It also comes one day after the Justice Department's internal watchdog office confirmed?it would review how the FBI obtained a warrant to monitor Trump foreign policy aide Carter Page, as well as the bureau's relationship with Christopher Steele, the author of the Trump dossier.Huber, who currently serves as the US attorney in Utah, may now find himself thrust into the middle of a fierce partisan struggle -- with Republicans arguing anything short of a special counsel is insufficient because the Justice Department cannot investigate its own people, and Democrats maintaining that any allegations of bias are an unfounded ploy to distract from Mueller's investigation into possible coordination between Trump campaign associates and Russian officials.Originally appointed by President Barack Obama in 2015, Huber, along with many other US attorneys, resigned after President Donald Trump took office early last year, but was reappointed by Trump shortly thereafter. 1845
