HONG KONG – Scientists at the University of Hong Kong claim to have the first evidence of someone being reinfected with the coronavirus that causes COVID-19.They said Monday that genetic tests show a 33-year-old man returning to Hong Kong from a trip to Spain in mid-August had a different strain of the virus than the one he’d previously been infected with in March.The man had mild symptoms the first time and none the second time, so his previous infection may have helped prevent serious illness.Experts say waning immunity could have implications for vaccine development and that the case shows the need to keep up social distancing and other prevention measures.Dr. Kelvin Kai-Wang To, who led the group of scientists, told The Associated Press that it’s unknown how many people can get reinfected, but there are probably more out there.Even if someone can be infected a second time, it’s not known if they have some protection against serious illness, because the immune system generally remembers how to make antibodies against a virus it’s seen before. 1069

Georgia's Republican Secretary of State says that despite voting for President Donald Trump and donating to his campaign, Trump threw him "under the bus" by attempting to overturn the results of the presidential election in the state.In an opinion piece for USA Today, Georgia Sec. of State Brad Raffensperger criticized Trump for refusing to "accept the facts" in narrowly losing the state to President-elect Joe Biden.In his opinion piece, Raffensperger noted that despite the circumstance, Georgia's elections went fairly smoothly, noting record numbers of mail-in and early voting and "minuscule" wait times on election day. But he said that all changed when Trump began publicly undermining trust in Georgia's elections."Elections are the bedrock of our democracy," Raffensperger wrote. "They need to be run fairly and, perhaps more important, impartially. That's not partisan. That's just American. Yet some don't seem to see it that way."As the head of elections in Georgia, Raffensperger has found himself at the center of attention since election day. Days after the polls closed, Raffensperger called for an unprecedented statewide audit of the presidential election in the state, which required a hand recount of election results.While the audit did find a few thousand votes for Trump that had not been previously counted, the new votes only represented a small change in the final tally. Georgia has certified its election, though the Trump campaign has filed for a machine recount of votes, which is unlikely to change the final tally.All the while, Trump has continued to cast doubt on the electoral process in the state — and Raffensperger says he's been personally pressured by fellow Republicans to find ways to exclude legally-cast ballots. He also says both he and his family have faced threats in the face of the recounts.In his piece, Raffensperger skewered both Republicans and Democrats who attempted to discredit the election process in the state."An onslaught of fake news and unrepentant disinformation threatened to tear the fabric of our country apart," he wrote. "People on both sides of the aisle generated controversies out of nowhere to stir up trouble."In particular, Raffensperger criticized Trump for "adopting the playbook" of Stacey Abrams, a Democratic gubernatorial candidate who lost out to Gov. Brian Kemp in 2018. Abrams never conceded to Kemp and only suspended her campaign after the state certified the results of the election.Raffensperger also went after Rep. Doug Collins, calling him a "failed sente candidate." Collins, who was eliminated from a Senate race this month, has been working with the Trump campaign in its efforts to overturn election results.Raffensperger closed his editorial by calling for more integrity from election officials."In times of uncertainty, when the integrity of our political system is most at risk, the integrity of our politicians is paramount," he wrote.Read Raffensperger's entire op-ed by clicking here. 2997

Garth Brooks has decided it’s someone else’s turn to win the Entertainer of the Year award from the Country Music Association Awards.The announcement came during a Facebook Live on Brooks’ page during a remote press conference.Brooks has won the award seven times."It's time for somebody else to hold the award and know what entertainer of the year feels like," he said.He said after last year’s CMA ceremony, there was one tweet that really stuck with him."It said, 'Why doesn't he step down and have entertainer of the year be for the next generation’. I 100 percent agreed," Brooks said.Brooks talked to the association about creating some sort of entertainer of the year emeritus.However, the Country Music Association said they were unable to control who is nominated for which category. “It’s not our call, we can’t pull you out of an award” they reportedly told Brooks.“We are going to do it ourselves. We are going to pull out from the entertainer of the year,” Brooks announced.Brooks said he is not withdrawing from other categories or award shows, "I'm very competitive, the awards mean the world to me" Brooks said. "With Entertainer, we've been lucky enough to walk home with that several times, and it's someone else's time."The nominations are expected to be announced in the next few weeks. 1314

FULLERTON, Calif. (AP) — Police say a suspect has been arrested in the stabbing death of a man at the California State University, Fullerton campus.Fullerton police Lt. Jon Radus on Thursday told The Associated Press that 51-year-old Chuyen Vo was arrested Wednesday night at his home in Huntington Beach. Vo is suspected in the death of a former co-worker, 57-year-old Steven Shek Keung Chan. Police would not elaborate on the work relationship between the two men.Chan worked as the director of budget and finance and student services for university extended education but retired in 2017. He returned to the campus in January to work as a consultant.Authorities have said Chan was found stabbed numerous times inside his silver Infiniti in a campus parking lot on Monday, and they believe it was a targeted attack. 825

Heavy rain caused a central Texas river to rise to a near-record level in about a day, leading to a bridge collapse, flooded homes and evacuations.The Llano River rose to nearly 40 feet Tuesday in the city of Llano -- about 35 feet higher than it was just 24 hours earlier before -- thanks to 8 to 10 inches of rain that fell in the area over the past two days, the National Weather Service said.A few miles away, in Kingsland, the swollen river rushed against the top of the RM 2900 bridge for hours, eventually causing it to collapse, video from CNN affiliate KEYE showed. No one appeared to be on the bridge, and no injuries were immediately reported.Video from Darlene Walthall also showed the river washing over the span before the collapse.The Llano County Office of Emergency Management ordered people living within a quarter mile of the river to evacuate Tuesday morning.The Llano River meets the Colorado River in Kingsland. Houses near the Colorado were flooded, resident Terri Kleen said. Video that she posted to Instagram showed water rising to the top of boat dock structures.Law enforcement officers were helping people from flooded areas, she said.In nearby Marble Falls, Dale Heath recorded video of a car stuck in rushing water from a swollen Backbone Creek, a Colorado River tributary.The flooded communities are about a 90-minute drive northwest of Austin.The Llano River's crest of 39.91 feet in Llano was just below the record high of 41.5 feet there in June 1935.The river is expected to recede through Tuesday afternoon, but should stay in the major flood stage -- over 23 feet -- through Wednesday morning. 1654
