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

The federal government has placed thousands of unaccompanied immigrant children in the homes of sponsors, but last year it couldn't account for nearly 1,500 of them.Steven Wagner, a top official with the Department of Health and Human Services, disclosed the number to a Senate subcommittee last month while discussing the state of the Office of Refugee Resettlement (ORR) that oversees the care of unaccompanied immigrant children.Wagner is the acting assistant secretary for the Administration for Children and Families, which is part of the Department of Health and Human Services. ORR is a program of the Administration for Children and Families.CNN reported earlier this month that, in his testimony, Wagner said during the last three months of 2017, the ORR lost track of nearly 1,500 immigrant children it had placed in the homes of sponsors.Wagner's statement has attracted more attention amid reports that immigrant children are being separated from their parents at the US border. 998

The European Union has announced it will reopen its borders to travelers from 14 countries, but most Americans have been refused entry for at least another two weeks due to soaring coronavirus infections in the U.S. Travelers from other big countries like Russia, Brazil and India will also miss out. Citizens from the following countries will be allowed into the EU’s 27 members and four other nations in Europe’s visa-free Schengen travel zone: Algeria, Australia, Canada, Georgia, Japan, Montenegro, Morocco, New Zealand, Rwanda, Serbia, South Korea, Thailand, Tunisia and Uruguay. The EU said China is “subject to confirmation of reciprocity,” meaning it must lift all restrictions on European citizens entering China before it will allow Chinese citizens back in.Tuesday’s decree will not apply to travel to Britain, which left the EU in January. Britain now requires all incoming travellers — bar a few exceptions like truck drivers — to go into a self-imposed 14-day quarantine, although the measure is under review and is likely to ease in the coming weeks. The requirement also applies to U.K. citizens.The list of permitted nations is to be updated every 14 days, with new countries being added or even dropping off depending on if they are keeping the disease under control.The daily number of new confirmed cases in the United States has surged over the past week. The U.S. has the world’s worst coronavirus outbreak, with nearly 2.6 million people confirmed infected and over 126,000 dead, according to a tally by Johns Hopkins University that experts say understates the pandemic’s true toll due to limited testing and other reasons.In March, President Donald Trump suspended all people from Europe’s ID check-free travel zone from entering the U.S.The EU imposed restrictions on non-essential travel to its 27 nations, plus Iceland, Liechtenstein, Norway and Switzerland, which are part of the Schengen open-borders area, in March to halt the spread of the virus. Non-EU citizens who are already living in Europe are not included in the ban.More than 15 million Americans are estimated to travel to Europe annually, and any delay would be a further blow to virus-ravaged economies and tourism sectors on both sides of the Atlantic. Around 10 million Europeans are thought to cross the Atlantic for vacations and business each year.___Follow AP coverage of the pandemic at https://apnews.com/VirusOutbreak and https://apnews.com/UnderstandingtheOutbreak 2475

The brother of an unarmed black man killed by police interrupted a Sacramento City Council meeting on Tuesday as chants of the victim's name filled the chambers, illustrating how the fatal shooting has sparked emotions in this California city."Stephon Clark. Stephon Clark," Stevante Clark and others chanted in the first meeting since the fatal shooting on March 18."Louder. Louder," said Stevante Clark, who hopped on the dais and yelled an expletive at Mayor Darrell Steinberg.Standing in front of the council chambers with others, Stevante Clark said: "The mayor and the city of Sacramento has failed all of you," citing high rent, gang violence and poverty in the city.The outburst forced council members to take a brief recess. 746

The digital news company Mic has laid off most of its staff, a spokesperson for the company confirmed.The layoffs were first reported Thursday by Recode. It is not yet clear exactly how many employees were affected. Mic declined to comment beyond confirming the Recode report.The company was founded in 2011, and for the past several years has branded itself as a news website geared toward millennials.Mic Publisher Cory Haik also resigned Thursday. In a note to staff that was obtained by CNN Business, Haik called journalism a "tough business.""Our business models are unsettled, and the macro forces at play are all going through their own states of unrest," she wrote. "If anyone tells you they have it figured out, a special plan to save us all, or that it's all due to a singular fault, know that is categorically false. Like the truth, it is indeed complicated."Mic was once a digital media darling, attracting around million in funding from investors. Its biggest backers included Lightspeed Venture Partners, Clark Jermoluk Founders Fund, WPP and WarnerMedia. (WarnerMedia owns CNN.)The company's staff swelled to more than 100 people by early 2016, according to The New York Times, which asked in an article published at the time: "What happens when millennials run the workplace?"But the climate is a tough one for digital media publishers right now. Ad revenue alone hasn't been enough to support these businesses, and Google and Facebook have substantial control over the ad market.Refinery29, HuffPost and Vocativ have all cut staff in the past year. So have CNN Digital, Vice and BuzzFeed.Mic laid off 25 employees in August 2017 as part of a pivot to video. Co-founder and CEO Chris Altchek told staff at the time that the shift was needed because "visual journalism already makes up 75% of the time that our audience spends" with the site.There were signs this year that the environment wasn't improving for Mic. Digiday reported in April that traffic to Mic's website had been plunging.The article also noted that Mic was very reliant on Facebook, citing statistics that showed views on the social media site fell to 11 million views in March compared to 192 million about a year earlier.Still, company executives pushed back on some reports that characterized the situation at Mic as particularly dire. When the Columbia Journalism Review reported in September that the company's board discussed a possible shutdown, Altchek called the report "categorically false."Emily Singer, a senior political reporter at Mic, tweeted Thursday that she was leaving the company."I'm so proud of what we've accomplished here," Singer wrote.Kerry Lauerman, Mic's executive news director, tweeted about the "gutting experience" Thursday."But only love for the extremely resilient and open-hearted team of Mic editors, producers, writers and shooters I had the great honor of working with," he added. "They performed brilliantly often under a cloud of uncertainty."Reached by phone, Lauerman declined to comment further, saying only that the team was packing up all of their things.Several other employees also tweeted news of their departures."I have so much to say, but most importantly the time I spent at @mic was the best of my career," wrote Managing Editor Colleen Curry. "I learned so, so much from brilliant people dedicated to keeping journalism alive."Mic is also in talks to sell at least part of the company to Bustle Digital Group, Recode reported Wednesday. A source with knowledge of the potential deal confirmed that report to CNN Business. 3572
