 Welcome to Friday's Overnight Health Care. Researching puppy behavior sounds like a dream assignment. But there's a big caveat: "There is nothing that will not be chewed or peed on." If you have any tips, email me at nweixel@thehill.com and follow me on Twitter at @NateWeixel Today: The CDC updated its guidance on distancing in schools, Biden gave a pep talk to agency scientists, and surging COVID-19 abroad should be a warning sign in the U.S. We'll start with schools: CDC says three feet of distance safe in schools The Centers for Disease Control and Prevention (CDC) on Friday said students need only be three feet apart in school, rather than six, so long as there is universal masking. The change is aimed at speeding the return to in-person learning. The recommendation is for all K-12 students, regardless of whether community transmission is low, moderate or substantial, the CDC said, but there is some nuance at the upper level grades. Middle school and high school students should be at least six feet apart in communities where transmission is high, the CDC said, if cohorting is not possible. According to the CDC, older students are more likely to be exposed to COVID-19 and spread it than younger children. The CDC also recommends six feet of distance in common areas, like lobbies and auditoriums, and during activities like singing, shouting, band or sport practices. Driving the change: Updated science. CDC published three new studies Friday that offer further evidence that schools can operate safely in person, even when community transmission of the virus is high and if distancing is less than six feet. Three feet is the minimum distance endorsed by the American Academy of Pediatrics and the World Health Organization. For many schools, keeping students six feet apart is not feasible. In some cases, there's no distancing at all. Unions not happy: American Federation of Teachers President Randi Weingarten said the union was "concerned this change has been driven by a lack of physical space rather than the hard science on aerosol exposure and transmission." Becky Pringle, president of the National Education Association, called on the CDC to provide far more details about its rationale. "We are concerned that the CDC has changed one of the basic rules for how to ensure school safety without demonstrating certainty that the change is justified by the science and can be implemented in a manner that does not detract from the larger long-term needs of students," Pringle said in a statement.

But Scott Gottlieb thinks there are better uses of the CDC's time and effort Former Food and Drug Administration Commissioner Scott Gottlieb said the agency should be making more of an effort to evaluate new variants of COVID-19, instead of reviewing rules for social distancing. Gottlieb's remarks came during an interview on CNBC's "Squawk Box" after being asked about the data on vaccines offering protections from new coronavirus strains. "This is what the CDC should be doing, not still arbitrating three feet versus six feet a year later," he said. "We should be on top of these new variants, evaluating what their clinical course is. We shouldn't have to wait months to get this information." Schools matter: Gottlieb has a point, and CDC has been criticized for moving too slowly. But the agency caught heat for being too restrictive in its school guidance last month, and they're attempting to rectify that. Daniel Benjamin, a pediatric infectious diseases specialist at Duke University, said anything to get schools open for in-person learning helps. "I don't know what's more important for the CDC to do right now," Benjamin said. Children "have been totally disenfranchised by a completely failed public policy of school closures, which has been a disaster. So absolutely, this should be happening right now."

Surging COVID-19 cases in Europe, Brazil signal warning for US Substantial surges in new coronavirus cases and hospitalizations in Europe and Brazil offer a worrying preview of what the United States faces in the coming weeks and months as the plummeting number of cases here begins to level off. The United States has reported an average of 54,740 cases per day over the past week, a steady decline from the apex of the outbreak in January, when the daily case count was about five times higher. Daily case counts stand about where they were in mid-October, and close to the apex of the summer surge that hit Sun Belt states particularly hard. But the precipitous drop that occurred through February is now nearing a plateau, one that could presage yet another spike in cases just as optimism about the course of the pandemic begins to take hold. Variant concern: The increase appears to be driven by spread among younger people, and by the emergence of the B.1.1.7 variant that studies show is substantially more infectious, even among children. That raises the specter that the variant will continue spreading widely even as older and more vulnerable people receive doses of vaccine. Optimism: But data from Israel, which leads the world in vaccinating its population, shows that the vaccines work against the 1.1.7 variant. Anthony Fauci this week said the U.S. is in a race, pitting the pace of vaccination against the increasing spread of variants. The race to vaccinate as many Americans as quickly as possible represents the first time in the entire pandemic that the United States has been on the leading edge of the battle against the coronavirus.

Biden jabs Trump in first visit to CDC President Biden on Friday made his first visit to the Centers for Disease Control and Prevention (CDC) headquarters since taking office to thank scientists and workers there for their efforts to fight the coronavirus pandemic. "We owe you a gigantic debt of gratitude, and we will for a long, long, long time," Biden told a small group of CDC officials gathered in an operations room. Biden repeatedly focused on his administration's respect for science, and broader support for a science-based approach to the virus among the public. The comments appeared to be a subtle jab at former President Trump, who repeatedly undermined his CDC director and other top health officials by offering unproven ideas about coronavirus treatments and misleading comments about the severity of the pandemic. "The public is thankful to you, because it's about science," Biden said. "That's what they understand. They understand. And we're not going back to the old days, even if tomorrow the whole administration changed. I think you've changed things. You've changed them in a way that are going to make everybody healthier in this country ... because you speak truth and science to power." Read more here. |
