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

Twitter users can now limit who can reply to their tweets.According to a blog post by Twitter's Director of Product Management Suzanne Xie, the new settings were rolled out on Tuesday."Since your Tweet = your space, we've been testing new settings to give people more control over the conversations they start," Xie said in the post. "Sometimes, people are more comfortable talking about what's happening when they can choose who can reply. We've seen people use these settings to have conversations that weren't really possible before. Starting today, everyone will be able to use these settings, so unwanted replies don't get in the way of meaningful conversations."Users can reply with the following three options: everyone, only people the user follows, or only people you, the user, mention. Before, anyone could respond.Xie explained that tweets with limited settings would be labeled, and the reply icon will be grayed out for people who can't reply. Those who can't answer will still be able to view, retweet, retweet with a comment, share, and like the tweets."These settings help some people feel safer and could lead to more meaningful conversations, while still allowing people to see different points of view," Xie said.According to the social media giant, they've received positive feedback. People said they felt more comfortable tweeting and more protected from spam and abuse, and 60% of people who used the new feature during the test didn't Mute or Block anyone, Twitter added. 1504

Uncle Ben's rice promised Wednesday to make changes to its brand image, hours after Aunt Jemima pancake mix and syrup promised to change its name and logo.Mars, the parent company of Uncle Ben's, did not say how it would make changes to the brand's name or logo but promised to "evolve the Uncle Ben's brand, including its visual brand identity," according to a statement on its website."We don’t yet know what the exact changes or timing will be, but we are evaluating all possibilities," the statement read. "Racism has no place in society. We stand in solidarity with the Black community, our Associates and our partners in the fight for social justice. We know to make the systemic change needed, it’s going to take a collective effort from all of us – individuals, communities and organizations of all sizes around the world."According to Uncle Ben's website, the name "Uncle Ben" refers to a "legendary Texan farmer, Uncle Ben who was known for his exceptionally high-quality rice." Frank Brown, a maitre d' at a Chicago restaurant, posed for "Uncle Ben's" portrait, which has since served as the brand's logo.Critics say the brand harkens back to slavery and Jim Crow-era South, where older black slaves and servants were frequently referred to as "Aunt" or "Uncle."On Wednesday, Aunt Jemima said it would remove it's logo — which has origins in minstrel show tropes — from packaging beginning in the fourth quarter of 2020 and would eventually rename the brand.The changes come as American institutions hold conversations about systemic racism amid weeks-long, largely peaceful protests in dozens of cities across the country. The protests were sparked by the death of George Floyd, who died in police custody in Minneapolis on Memorial Day. 1757
