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 our country works to rebound, we're helping you manage the pressure as the pandemic is shifting caregiving responsibilities.More millennials are taking on this responsibility now. They're becoming a greater percentage of what's known as the "sandwich generation." Those are people who are caring for both their own kids and their aging parents.New numbers from insurance company New York Life show a third of millennials are doing this now.“We're not replacing the typical 49-year-old woman who's the family caregiver. She's still doing it, but the need is so great that more and more young people are called into the role as well and that's going to continue well after the COVID pandemic,” said John Schall, CEO of the Caregiver Action Network.Nearly half of the so-called "sandwich generation" expect to be a caregiver in some capacity for six or more years.The added financial strain is one concern. Schall says out of pocket expenses can be about a thousand dollars a month.More than half of these caregivers say they're spending more than usual per month to care for others as a result of the pandemic. That means they're contributing less to their savings and their retirement.There's also the concern about the mental toll.“With millennial generation caregivers, you may not be thinking about depression, you know, at that age, but the fact is the sheer stress of the role of being a family caregiver increases that risk of depression twice as often,” said Schall.If you are feeling overwhelmed, the caregiver help desk from the Caregiver Action Network can be one place to turn. You can call them free of charge at 855-227-3640. 1648

At a briefing on Friday, Press Secretary Kayleigh McEnany said the White House condemned Hong Kong's decision to delay its legislative council elections amid the coronavirus pandemic — a day after the president suggested delaying the 2020 presidential election.On Friday, Hong Kong announced it would be pushing its elections back a year, citing concerns regarding the spread of COVID-19. Pro-democracy lawmakers in the semi-autonomous city say the move was an attempt by the pro-China majority to disenfranchise voters.When asked for the White House response to Hong Kong's decision, McEnany read a prepared statement."We condemn the Hong Kong government's decision to postpone for one year its legislative council elections and disqualify opposition candidates," the statement read, in part. "This decision undermines the Democratic process and freedoms that underpin Hong Kong's prosperity, and this is only the latest in a growing list of promises by Beijing that promised autonomy and freedoms to the Hong Kong people."On Thursday, President Donald Trump floated a delay of the 2020 presidential election in a tweet, citing his concerns with mail-in voting. It was just the latest in a series of several misleading tweets Trump has posted that push dubious information about mail-in voting.The Constitution grants Congress the responsibility to set the dates for federal elections. The current election day date — the first Tuesday in each November — was established in a 1948 law.Several top Republican lawmakers, including Senate Majority Leader Mitch McConnell and House Minority Leader Kevin McCarthy said they would not support a bill to move the election. 1674
