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

BALTIMORE — BALTIMORE, M.D. - It’s Cyber Security Awareness month and the FBI wants to warn people about potential scams, especially while so many are working and going to school virtually.One Montgomery County man, who wants to stay anonymous, was scammed out of thousands of dollars using a dating app and doesn’t want others to make the same mistakes."Emotionally, it’s like there are claws in you that you can't seem to get out," said D. For years, the man who we are calling 'D' thought he was in a caring online relationship, but just last month, he found out it was all a scam."I was a little lonely. I was needing some attention or I guess I just wanted some," said D.It started 5 years ago. Divorced, he had turned to date apps Skout and Meet Me to fill that emotional void and met Brandy Bowens from Canada. It seemed like an innocent relationship for a while, but then she started asking him to be the middle man for her "art business"."By me already being invested in our conversations and our online relationships, I kind of felt it was okay for me to do these things that they wanted," said D.So he started getting money transferred to his bank account that he would then send out in cashiers checks."I had received three wire transfers of over 0,000 and these monies they claimed were for their business," said D. It kept adding up... and then she asked for his money.It all came to a head last month when he got a call from the FBI saying it was all a scam; his ,000 was gone."It's hard. I lost the money and it messed up everything in a financial way for me. I'm trying to build my credit back, just so much that that has screwed up for me," said D.FBI Special Agent Jeffrey Reising said these scams are even more common now during the pandemic because criminals are taking advantage of government programs like unemployment and funneling the money through romance scam victims, like D."Just red flags, like 'Why am I getting unemployment in other people's names in my account? Why am I getting tens of thousands of dollars in my account'?" said Reising.Other red flags to look for are if they can never meet in person, or even answer phone calls, if they don’t have a real voicemail or if they ask for your bank account."Why can I not talk to this person face to face using some of the technology available? Why can’t I interact? Why is all of our communication on a text?" said Reising.It’s red flags D saw, but the scammer could explain away."Saying 'my phone is broke' or 'my camera doesn’t work'," said D.Now he’s sharing his story, hoping that especially during this virtual time, he can stop others from falling victim."Be cautious. If you get that flag, if you don’t get the answer for that flag, then you need to leave it alone," said D. If you think you might be a victim of a romance scam, contact your local FBI office or file a report online. This story was first published by Abby Isaacs at WMAR in Baltimore, Maryland. 2964

As the Thanksgiving holiday approaches, college campuses across the country will empty out. Tens of thousands of students will head home for the break, and public health experts fear mass travel and indoor gatherings could spark a super spreading of the coronavirus.Within days of returning to campus this fall, Brianna DeWall contracted the coronavirus.“We went out to party, and with all my friends, got it,” recounted the Oklahoma State University junior. “So, we're assuming someone at that party had it and didn't know.”According to the Centers for Disease Control and Prevention (CDC), the return to college campuses in August and September coincided with a 55 percent increase nationally of COVID-19 cases in young adults ages 18 to 22.Next week, DeWall is headed home for the holidays, but she plans to get tested before she travels.“I will be flying, so I feel like that's a precaution I should take,” said DeWall.While her school isn’t requiring mandatory exit testing, other schools are.Penn State is offering free, voluntary exit tests. The University of Michigan has made exit testing mandatory, and New York State’s university system is also mandating a negative test result for all of its 140,000 students before they leave campus.“Some people may get a test that's not going to decrease the risk to zero, but it is going to decrease the risk substantially,” said Dr. Amesh Adalja, a senior scholar with the Johns Hopkins Center for Health Security.Dr. Adalja warns that without extra precautions like frequent testing, mask-wearing, social distancing, and self-quarantining ahead of the holiday, the risk of community spread is increased.“It is going to be a major challenge when you have your student body moved from campus back home and come back on campus because that's likely to introduce more levels of infection,” he said.Earlier this year, researchers at Ball State University tracked 7.5 million students at more than 1,300 universities and concluded that thousands of college students may have picked up COVID-19 while at densely-packed spring break destinations, only to return to infect others with the virus.Some schools like DeWall’s are not having students return to campus until January and have canceled spring break. But once again, testing is voluntary.“I think we should have to get tested before we come back,” said DeWall. “I think it's very careless that they aren't requiring us to get tested before we go home.”The CDC hasn’t issued any specific COVID-19 guidance on colleges and break, and while the American College Health Association encourages testing, it stops short of calling for it to be mandatory.“Colleges we know have been hot spots for infection, especially with off-campus activity,” said Dr. Adalja. “So, I do think this is going to be particularly challenging to accomplish.” 2839

ATLANTA — Georgia’s top elections official says his office is investigating potential election law violations by groups working to register voters ahead of January's Senate runoffs. Secretary of State Brad Raffensperger named four groups his office is specifically investigating: America Votes, Vote Forward, The New Georgia Project and Operation New Voter Registration Georgia. He says some groups are allegedly encouraging people outside the state to register to vote in January's Senate run-off election, according to The Hill. “We have opened an investigation into a group called America Votes, who is sending absentee ballot applications to people at addresses where they have not lived since 1994,” Raffensperger said Monday in announcing the investigations. America Votes responded to the accusations in a statement to the Atlanta Journal Constitution, saying they have mailed applications to those on the list of voters maintained by Raffensperger's office. The secretary is also punching back at claims that fraud has tainted the state’s presidential election. Raffensperger said dishonest actors are exploiting the emotions of many Trump supporters with fantastic claims and apparently misleading the president as well. He said during a news conference Monday that his office has 23 investigators probing 250 open cases alleging some kind of election law violation, but none of them cast doubt on the integrity of the state's election results. 1461

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
