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 Vietnam veterans grow older, the National Park Service said it has seen an increase in people leaving remains at the Veteran's Memorial Wall in Washington D.C., so it has now put up signs asking people to stop.Nancy Skinner wanted to honor her fiance Ron Looney after he died in 2008. When he died, Skinner had him cremated.Other than Looney's remains, photos were one of the few things she had left of Looney. The snapshots capture the motorcycle trips the couple took around the country, family get-togethers, and even Looney’s time in the Vietnam War.“He was over there five times,” recalled Skinner.Soon after his death, she took some of Looney's ashes and set out on one last adventure with him. “I went ahead and got what I thought would probably be the right amount if you cremated his heart, the right amount size,” said Skinner.She packed the ashes in a wooden box and drove from Mississippi to Washington, D.C., to leave Looney's cremains at the Vietnam Veteran's Memorial Wall.“It was something he so wanted to do, so wanted to be there. I knew that was something he would have wanted,” said Skinner.The National Park Service said Looney’s cremains are one of about 70 that have now been left at the wall over the years.“A lot of Vietnam veterans feel very connected to the memorial. It speaks to them in a way a lot of other places in the country don't,” said Janet Folkerts, a curator with the Park Service. “Cremains are kind of definitely more sensitive and something that needs a higher standard of care than we're really equipped to deal with here,” said Folkerts.The cremains left at the wall are currently brought to a Park Service building and kept in a metal storage cabinet. But Folkerts said the Park Service is looking into new options.“We’re hoping some veterans cemetery could help us with the cremains we already have and we could setup some system in the future,” she said.While Skinner said she understands the Park Service’s concerns, she hinted she would still have found a way to honor Looney’s wishes.“I made it a pretty little box. And I didn't figure anybody would mind. Makes me wonder if I need to go back and pick him up. But his ashes are still gonna stay there. Sorry," Skinne said.  2274

At a press briefing in Washington on Friday, Vice President Mike Pence said the White House coronavirus task force had identified 16 states — about one-third of all states in the nation — where COVID-19 cases are on the rise.According to Pence, in the other 34 states, there is a "measure of "stability" among cases — saying that while these states may experience new cases, "positivity rates are stable."Pence said that most of the states with rising cases are in the "Sun Belt." He said that he and other health officials would travel to Arizona, Florida and Texas — three states experiencing severe spikes in cases — next week, to meet with governors.The task force reported that a majority of new cases have been reported in people younger than 34 — a development that Pence called "encouraging" in some ways because young people are more likely to recover from the virus.According to Pence, there have been 2.5 million confirmed cases of the virus in the U.S. According to Johns Hopkins, there are about 4,425,000 confirmed cases of the virus.During Friday's briefing, Dr. Anthony Fauci — America's top expert on infectious diseases — said that some areas of the country as facing a "serious problem" amid rising numbers. He added that Americans have a "societal responsibility" to continue social distancing, adding that those who leave their home for crowded places become part of an infectious chain."Ultimately, you will infect someone who is vulnerable," Fauci said.The task force and President Donald Trump held near-daily briefings throughout March and April. But the nation's top health experts have rarely appeared on-camera in recent weeks as the administration has focused on re-starting the economy.The briefing comes a day after Johns Hopkins reported 40,000 new cases of the novel coronavirus, the highest single-day increase since the pandemic began. President Donald Trump has maintained that the increase in cases is the result of increased testing capacity, but the CDC reports hospitalizations linked to the virus are also on the rise.It also comes following a week of confusing messaging regarding the administration's policy on testing. On Saturday at a rally in Oklahoma, Trump told supporters that he asked that testing be "slowed down" to deflate new case numbers artificially. On Monday, press secretary Kayleigh McEnany said Trump made those comments "in jest," but Trump quickly contradicted her, saying he "doesn't kid." Dr. Anthony Fauci, the nation's top infectious disease expert, later testified at a House committee hearing that he had not been told by anyone in the administration to slow down testing, and that increasing testing capacity remains the goal of the task force.Several states that were quick to lift lockdown restrictions are now moving to re-impose social distancing measures. On Friday, Texas ordered the closure of bars and re-imposed limits on in-restaurant dining. Also on Friday, Florida ordered that bars can no longer serve alcohol on-site as cases continue to spike. 3036
