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

ATLANTA (AP) — Georgia’s governor, Brian Kemp, is explicitly banning the state's cities and counties from ordering people to wear masks in public places.He’s voiding orders that at least 15 local governments across the state had adopted even though Kemp had earlier said cities and counties had no power to order masks.The Republican governor has instead been trying to encourage voluntary mask wearing.An increasing number of other states have ordered residents to wear masks in public, including Alabama, which announced such a ban Wednesday.Kemp’s move is likely to infuriate local officials in communities that had acted, including Atlanta, Augusta, Savannah, Rome and the governor’s hometown of Athens-Clarke County. 729

As students begin to head back to the classroom – either virtually or in person – this month begins the most uncertain school year in recent memory.While some public health experts have expressed apprehension about reopening schools, President Donald Trump gave a full-throated defense for bringing back students into classroom full time this fall. Trump hosted a group of educators and school administrators at the White House on Wednesday.Amid Trump’s effort to reopen schools, the CDC released updated guidance last month that emphasizes reopening schools. The new guidance contradicts previous guidance, which recommended closing schools during periods of substantial community transmission.The updated guidance said that extended school closures are harmful to children and can lead to severe learning loss, and the need for in-person instruction is particularly important for students with heightened behavioral needs.During an event with educators on Wednesday, Trump said not only should students return to the classroom, but he decried hybrid schedules, which incorporates a blend of in-person and virtual learning. Proponents of hybrid schedules say that they allow for students to have some in-person learning while opening more classroom space for social distancing.But the president is not a fan.“The concept of every other day seems a little ridiculous, right?” Trump said. “If you are going to do it, you do it. If you are not going to do it, the concept of going back even from a management standpoint from the school, every other day seems very strange.”Trump once again called on Congress to pass 5 billion in education funding, which House Democrats have also pushed for as part of a broader stimulus plan. While Treasury Secretary Steven Mnuchin said the White House is open to doing a piecemeal approach to a stimulus package, House Democrats have pushed for an all-encompassing bill.Some of the funding for schools could be used to help districts with additional costs associated with mitigating the risk of the virus.Trump said that the funds should follow the students. He has previously said that if schools opt for online learning, they should not receive federal funds.“If the school is closed, you know, why are we paying if a school is closed?” Trump asked. “Why are we paying the school if it is closed? I would rather give it to the student, the parents, and you do your own thing, and to me it makes a lot of sense.”While Trump is eager for a full return to school, there are several cautionary anecdotes from several districts that opened earlier this month.Most notably, the Cherokee School District in Georgia reported on Tuesday 59 students and employees tested positive for the coronavirus following its reopening. The district is now asking 925 employees and students to quarantine for two weeks. The district’s Etowah High School will remain closed until August 31 due to the outbreak. 2935
