Two studies recently published in the CDC’s journal indicate COVID-19 can spread on airplanes.In one study, researchers found a woman showing symptoms on a 10-hour flight potentially spread COVID-19 to at least 15 other people on the plane.A 27-year-old businesswoman who lived in London and was from Vietnam started having symptoms, fever and cough, while still in London in late February. She and her sister had visited Italy and other locations in London before the woman flew to Vietnam. Her sister later tested positive for COVID-19.The 27-year-old was one of 21 people sitting in business class on the March 1 flight from London to Hanoi, Vietnam. The woman became more sick once she landed, and isolated in her home. A few days later, she tested positive for COVID-19, as did three people in her house and a friend back in London she had visited before the flight.Researchers quickly tracked down the majority of people who were on the woman’s flight to isolate and trace potential cases.In all, researchers identified 14 additional passengers and one crew member who had COVID-19. The study states 12 of the passengers who tested positive had sat in business class with the 27-year-old woman, and 11 of them were sitting within two seats of her.“First, thermal imaging and self-declaration of symptoms have clear limitations, as demonstrated by case 1 (the woman), who boarded the flight with symptoms and did not declare them before or after the flight. Second, long flights not only can lead to importation of COVID-19 cases but also can provide conditions for superspreader events,” researchers concluded.The second study looked at four people aboard a flight from Boston to Hong Kong on March 9 who all tested positive for COVID-19 after landing in Hong Kong and showing symptoms. Two passengers, a couple, flew in business class. They showed symptoms the day they landed and sought healthcare.The other two cases were flight attendants who served the business class and first class sections of the plane. Both had come into close contact with the couple, and they both developed symptoms a few days after landing.Researchers were able to sequence their viruses and discovered all four had the same strain of COVID-19.Scientists conclude the couple contracted COVID-19 while they were in the U.S. and transmitted it to the flight attendants on the plane.“Passengers and cabin crew do not generally go through the same check-in process at airports before boarding. Although we cannot completely rule out the possibility that (the flight attendants) were infected before boarding, the unique virus sequence and 100% identity across the whole virus genome from the 4 patients makes this scenario highly unlikely,” researchers stated.Although there were no other positive COVID-19 cases reported from this flight, not all passengers were tested or tracked like in the first study.“Our results demonstrate that SARS-CoV-2 can be transmitted on airplanes. To prevent transmission of the virus during travel, infection control measures must continue,” they noted.Both of these studies looked at cases on flights before face coverings were mandatory on flights. They were published in Emerging Infectious Diseases, a journal of the Center for Disease Control and Prevention. 3286

Tropical Storm Eta has dumped several inches of rain across the northern peninsula of Florida on Wednesday night and Thursday morning. But while the storm has caused some flooding and has left several thousand people without power, the state has largely been spared of major widespread damage. 301

TUCSON, Ariz. (AP) — President Donald Trump's dad dancing to the Village People's "YMCA" is turning out to be a hit at his campaign rallies. On stage, Trump pumps his fists, bops, and lurches — sometimes to the beat. Backstage, top staff and campaign aides often join in, offering more traditional moves and using their bodies to spell out Y-M-C-A. Trump's rally dance has emerged as a rare moment of levity in an otherwise miserable campaign year marked by a deadly pandemic, an economic recession, and racial turmoil. His dance has spawned a TikTok video challenge and a parody on "The Late Show with Stephen Colbert." 628

VALLEY CENTER, Calif. (KGTV) — A week after a cancellation of a holiday tradition at a cemetery in Valley Center, a community wrapped up their campaign to save Christmas for many military families.Because of COVID-related issues, the nonprofit that places more than 300 Christmas wreaths at military grave markers at Valley Center Cemetery announced Friday it wouldn't be able to this year."I just felt defeated ... My heart dropped," said Jenelle Brinemann.Brinemann, a local florist, decided to post on Facebook a call for donations to make wreath sprays, a smaller version of wreaths."It shows we have Christmas spirit still, even during this hard time," said Brinemann.A day later, her driveway was filled was with donated cedar, pine, and ribbons. More than 50 volunteers signed up to help assemble. Kids sent messages to attach to the sprays and on Wednesday, the project was completed."Great way for the town to come together ... shows there's still love in the world," said Brinemann.Among those who stepped up were members of the Green Knights Military Motorcycle Club, who saw our story on the wreath campaign, and volunteered their services.On this day, they escorted the volunteers to the cemetery."We felt we had to help them, because it was the right thing to do. We have to honor our veterans that have gone before us," said club member Tyler Nelson."It was overwhelming. The whole neighborhood turned out, cheering. They had posters. Best Christmas present someone could receive," said Brinemann.At the cemetery, Brinemann and seven others quietly placed the wreath sprays at 311 grave markers."The cemetery just looks like how it should be now," said Brinemann. 1686

Two days after President Donald Trump’s visit to the city, Democratic nominee Joe Biden met with members of Jacob Blake’s family on Thursday before hosting a community discussion on race.Ben Crump, a civil rights attorney who is representing the Blake family, said that the former vice president met with Blake's family for nearly 90 minutes. Blake joined for part of the conversation via telephone from his hospital bed, both Crump and Biden confirmed.“The family was grateful for the meeting and was very impressed that the Bidens were so engaged and willing to really listen,” Crump said. “Jacob's mother led them all in prayer for Jacob's recovery. They talked about changing the disparate treatment of minorities in police interactions, the impact of selecting Kamala Harris as a Black woman as his running mate. and Vice President Biden's plans for change. Mr. Blake Sr. talked about the need for systemic reform because the excessive use of force by police against minorities has been going on for far too long.”Biden said that Jacob Blake told him “nothing is going to defeat” him."I had an opportunity to spend some time with Jacob [Blake] on the phone. He's out of ICU. We spoke for about 15 minutes. His brother and two sisters, his dad and his mom on the telephone," Biden said.Blake was shot seven times in the back by Officer Rusten Sheskey last month. Sheskey has been placed on administrative leave per police policy.While Sheskey has not been charged with a crime, Biden said earlier this week that charges should be filed.“I do think there's a minimum need to be charged,” Biden said, also adding that the Louisville, Kentucky, officers involved in the death of Breonna Taylor should also be criminally charged.Biden told Kenosha community members that fighting for racial equality “is something worth losing over." He added, "But we're not going to lose."While Biden said that he would make addressing systematic racism a priority if elected in November, Trump said on Tuesday that he does not believe systematic racism is a problem in police/community relations."I don't believe that,” Trump said during his visit to Kenosha on Tuesday. “No, I don't believe that. I think the police do an incredible job. And I think you do have some bad apples. I think you'd agree every once in a while you'll see something. And you do have the other situation too, where they're under this tremendous pressure and they don't handle it well. They call it choking and it happens."Biden promised community members in Kenosha that he would form a policing commission, vowing to invite the police and civil rights leaders to the same table. 2649
