Coronavirus live updates: LA cracks down on 'nightclub' house; Las Vegas casinos could be inflaming COVID spread; Florida marks 10K deaths

As COVID-19 outbreaks at schools continue to pop up causing students and staff in some states to quarantine, a new study suggests that children may play a larger role in community spread of the new virus than previously thought.Researchers in Massachusetts found that some children who tested positive for COVID-19 had significantly higher levels of virus in their airways than hospitalized adults in intensive care units, according to the study published Thursday.“Kids are not immune from this infection, and their symptoms don’t correlate with exposure and infection,” said Dr. Alessio Fasano, the study's senior author.Meanwhile, two days after the University of North Carolina announced it would pivot to online classes, university officials announced Wednesday that it would temporarily suspend all athletic activities until Thursday afternoon. Researchers at Massachusetts General Hospital and Mass General Hospital for Children found that among 192 children, 49 tested positive for the coronavirus and had significantly higher levels of virus in their airways than hospitalized adults in intensive care units, according to the study published Thursday in the Journal of Pediatrics.Study author Dr. Alessio Fasano said some children exhibited symptoms, but others showed no symptoms and were brought in because they had been in contact with an infected person or lived in what was considered a high-risk area.“Kids are a possible source of spreading this virus,” Fasano said. Some of those smartphones then traveled to every state on the mainland except Maine.Here’s a look at where those devices ended up during those same four days, according to Propublica: The cellphone analysis highlights a reason the virus keeps spreading and shows how travel to Las Vegas could be fueling the pandemic, according to health officials.– Ed Komenda, Reno Gazette JournalJust 48 hours after saying a COVID-19 outbreak on campus wouldn't affect plans to play football this fall, the University of North Carolina has suspended all athletic activities through at least Thursday afternoon.
