The fine print of newly released federal guidelines for reopening schools raises serious questions about whether in-person classes should resume at a time when COVID-19 rages around much of the country.Last week, the Centers for Disease Control and Prevention (CDC), under pressure from the White House, released a position paper highlighting “the importance of reopening America’s schools this fall.”But separate guidelines issued for K-12 school administrators, which drew less public attention, are much more cautious.“It is important to consider community transmission risk as schools reopen,” those CDC guidelines state.“Computer simulations from Europe have suggested the school reopenings may further increase transmission risk in communities where transmission is already high.”Buried at the bottom of the new CDC recommendation to re-open schools is a HUGE caveat! #COVID19 poses a low risk to kids “at least in areas with low community transmission.” That’s not where much of the country stands right now. 4/ pic.twitter.com/0D5CPxhlIb— Phil Williams (@NC5PhilWilliams) July 25, 2020 The new CDC guidelines suggest, “If community transmission levels cannot be decreased, school closure is an important consideration.”“Plans for virtual learning should be in place in the event of a school closure.”In Tennessee, several public and private schools are preparing to reopen even as almost every county in the state is showing what the Department of Health considers to be unacceptable rates of transmission of the coronavirus.Last week, the American Academy of Pediatrics issued a dramatic clarification of its statement back in June that "all policy considerations for the coming school year should start with a goal of having students physically present in school.""This does not mean that we recommend that all schools open five days a week from the start of the school year," the academy’s Dr. Sean O'Leary told a congressional committee.“Many parts of the country are currently experiencing uncontrolled spread of COVID-19. While the AAP urges those areas to make in-person learning as the goal, we recognize that many jurisdictions will need to utilize distance learning strategies until cases decline."The vice chair of the academy's committee on infectious diseases, O'Leary told the subcommittee that, where there is uncontrolled community transmission, "it's inevitable that the virus is going to get into the schools, and schools are going to have to shut down."U.S. Surgeon General Jerome M. Adams also told CBS This Morning last week that a community's COVID-19 transmission rate is the single most important determinant of whether schools can safely reopen.School reopening advocates point to the emotional, psychological and educational importance of children being in the classroom – a position that the CDC guidelines reaffirm.“Schools provide safe and supportive environments, structure and routines for children, as well as other needed support services to children and families,” the CDC notes.Children are less likely to become ill when infected with the virus, and younger children are less likely to transmit the virus to others, the report adds.But a large-scale study out of South Korea recently reported that children ages 10-19 -- middle- and high-school ages -- can spread the virus as easily as adults.Also, in searching citations in the new CDC recommendation to re-open schools, it appears to completely leave out the large-scale South Korea study that found teens are likely to spread #COVID19 as readily as adults 5/ https://t.co/ABLPvpKQU5— Phil Williams (@NC5PhilWilliams) July 25, 2020 In addition, a new study – shared by the Tennessee Department of Health last week on Twitter – concluded that “young, previously healthy adults can take a long time to recover from COVID-19.” 3828

The CDC is considering changing its quarantine guidelines for those who have been in close contact with someone who is infected with the coronavirus.Currently, those who have been in close contact with someone infected with the virus would be advised to quarantine for 14 days. Possible new guidance would shorten the quarantine period to 10 days. At the end of the 10-day period, a test would be need to end quarantine.In an interview with CNN’s Wolf Blitzer, Adm. Brett Giroir, the assistant secretary for health at Health and Human Services, explains why a 10-day quarantine might be more effective at getting more compliance with the guidance."People are much more likely to listen to a 10-day quarantine than they are a 14-day quarantine,” Giroir said. “If we can shorten it safely with most risk because we have a quarantine plus a test, we have a lot of tests available now, that might improve our public health responses.”Giroir stressed that final guidelines have not been approved, and the current guidance still calls for a 14-day quarantine.“It's not an announcement that is happening but we are reviewing it and the CDC team is modeling it and looking at data every day,” Giroir said.“And it may change or it may not. Just depends on where the data and the evidence wind up." According to the CDC, a person can become infected with the virus up to 14 days following exposure. But researchers say most illnesses begin five to seven days after COVID-19 exposure.A close contact is considered someone who is within 6 feet of someone with the virus for a period of 15 minutes or more over the course of a day. 1626

The engine came roaring back to life, despite the vehicle being partially burned and melted. And though their car may not look pretty, Christina Lopez and her husband concluded the fire-damaged Honda Civic was safe enough to drive.Lopez said she was anxious to have her car so she could drive to work and take her 18-month-old son to day care. Her husband's car was lost in the fire.A locksmith had to make a new key because the previous one was lost, along with everything else they owned, inside their now-destroyed home. 531

The country is heading into a COVID-19 winter without fully deploying widespread testing of sewage for traces of coronavirus, a Newsy investigation has found.Wastewater surveillance is one of the few proven tools able to track community spread of the disease, with the potential to help monitor immunity rates from new vaccines."It is frustrating," said David Larsen, an associate professor of public health at Syracuse University's Falk College. "We're going to see a huge amount of sadness over the next few months. And it's not too late to scale up wastewater surveillance at this time to help us with that."Early on, scientists realized infected people shed the virus in stool.The federal government began a big effort for analyzing the concentration of the virus in community wastewater."It's something I think from a national level we need to pursue," Assistant Secretary for Health ADM Dr. Brett Giroir said during a July webinar.Months later, the government has left it to state and local authorities to launch their own programs.For some, that's been a challenge.Newsy learned New York State, for example, suspended its sewage surveillance pilot after a month in part because of an equipment shortage.As a result, testing stopped in four places including Albany and Erie County, home of Buffalo.The University of Buffalo helped lead the project."UB is in the process of acquiring enough materials to continue the monitoring effort moving forward," university spokesman Cory Nealon said in an emailed statement.As with PPE, there is a global shortage of supplies needed to test sewage for COVID.Other places are struggling with how to pay for sewage analysis, with coronavirus aid from Washington running dry."The biggest factor, the limiting factor, is finances," Larsen said.The result is a patchwork of places examining wastewater across the country, mainly big cities and college campuses."It's not really a unified strategy, unfortunately," said Colleen Naughton, an assistant professor of civil and environmental engineering at the University of California Merced.She and her team plot testing sites on a map."When you zoom out of course the bubbles are big, so it looks like all U.S. is covered," Naughton said. "But when you zoom in you see it's a bit more spread out."Three states, Iowa, Rhode Island and South Dakota, don't have any surveillance sites at all, she said.Biobot Analytics looks for COVID in wastewater for about 200 cities and counties but has the capacity to do much more, said company president and cofounder Newsha Ghaeli."We're at the beginning, let's say that," Ghaeli said. "There hasn't really been a strong coming together yet around a specific approach or even standards."The CDC is still putting together a national wastewater surveillance system, building out a database not available to the public yet."It is, I think, valuable for the public to see that data and take action as a deciding factor for what activities and what risks am I going to take?" Naughton said. 3019
