According to several media outlets, the US-Canada land border would reportedly remain closed until November.CTV News reported that restrictions would remain in place until it is felt that the coronavirus pandemic is under control.The current agreement was set to expire on Sept. 21.On March 20, the travel ban was first imposed and it's been renewed every month since then. 381

According to a study published by UCLA's Anderson School of Management, the COVID-19 pandemic has put the U.S. economy into a "depression" and projects that the country's GDP won't return to pre-pandemic levels until early 2023.The study was published by David Shulman of UCLA's Anderson Forecast — a research firm at the school that publishes a quarterly outlook on the U.S. economy."Make no mistake, the public health crisis of the pandemic morphed into a depression-like crisis in the economy," Schulman wrote. "To call this crisis a recession is a misnomer."The report says that despite a drastic response from both the Trump Administration and the Federal Resevre, it will take years for both employment levels and GDP to return to were it was before COVID-19 reached America."Simply put, despite the Paycheck Protection Program too many small businesses will fail and millions of jobs in restaurants and personal service firms will disappear in the short-run," the report reads. "We believe that even with the availability of a vaccine it will take time for consumers to return to normal. (It took more than two years after 9/11 for air travel to return to its prior peak.) With businesses taking on a huge amount of debt, repayment of that debt will take a priority over new capital spending. And do not forget that state and local budgets suffered a revenue collapse that even with federal assistance it will take years to recover from."The U.S. lost 22 million non-farming jobs in the early months of the pandemic, the report says. The report does offer at least one bright spot: the housing market. The report mentions that despite high unemployment rates, "consumer demand remains strong" and that markets will return to pre-pandemic levels fairly soon.Finally, the report projects that the pandemic will accelerate some trends that were already in motion, particularly the growth of online retail, telecommuting and rising tensions between the U.S. and China. 1980

After struggling to ramp up coronavirus testing, the U.S. can now screen several million people daily, thanks to a growing supply of rapid tests. But the boom comes with a new challenge: keeping track of the results.All U.S. testing sites are legally required to report their results, positive and negative, to public health agencies. But state health officials say many rapid tests are going unreported, which means some new COVID-19 infections may not be counted.And the situation could get worse, experts say. The federal government is shipping more than 100 million of the newest rapid tests to states for use in public schools, assisted living centers and other new testing sites.“Schools certainly don’t have the capacity to report these tests,” said Dr. Jeffrey Engel of the Council of State and Territorial Epidemiologists. “If it’s done at all it’s likely going to be paper-based, very slow and incomplete.”Early in the outbreak, nearly all U.S. testing relied on genetic tests that could only be developed at high-tech laboratories. Even under the best circumstances, people had to wait about two to three days to get results. Experts pushed for more “point-of-care” rapid testing that could be done in doctors offices, clinics and other sites to quickly find people who are infected, get them into quarantine and stop the spread.Beginning in the summer, cheaper, 15-minute tests — which detect viral proteins called antigens on a nasal swab — became available. The first versions still needed to be processed using portable readers. The millions of new tests from Abbott Laboratories now going out to states are even easier to use: they’re about the size of a credit card and can be developed with a few drops of chemical solution.Federal health officials say about half of the nation’s daily testing capacity now consists of rapid tests.Large hospitals and laboratories electronically feed their results to state health departments, but there is no standardized way to report the rapid tests that are often done elsewhere. And state officials have often been unable to track where these tests are being shipped and whether results are being reported.In Minnesota, officials created a special team to try and get more testing data from nursing homes, schools and other newer testing sites, only to be deluged by faxes and paper files.“It’s definitely a challenge because now we have to do many more things manually than we were with electronic reporting,” said Kristen Ehresmann, of the Minnesota Department of Health.Even before Abbott’s newest BinaxNOW rapid tests hit the market last month, undercounting was a concern.Competitors Quidel and Becton Dickinson have together shipped well over 35 million of their own quick tests since June. But that massive influx of tests hasn’t showed up in national testing numbers, which have mostly ranged between 750,000 and 950,000 daily tests for months.Besides tallying new cases, COVID-19 testing numbers are used to calculate a key metric on the outbreak: the percentage of tests positive for COVID-19. The World Health Organization recommends countries test enough people to drive their percent of positives below 5%. And the U.S. has mostly been hovering around or below that rate since mid-September, a point that President Donald Trump and his top aides have touted to argue that the nation has turned the corner on the outbreak. The figure is down from a peak of 22% in April.But some disease-tracking specialists are skeptical. Engel said his group’s members think they aren’t getting all the results.“So it may be a false conclusion,” he said.One of the challenges to an accurate count: States have wildly different approaches. Some states lump all types of tests together in one report, some don’t tabulate the quick antigen tests at all and others don’t publicize their system. Because antigen tests are more prone to false negatives and sometimes require retesting, most health experts say they should be recorded and analyzed separately. But currently the vast majority of states do not do that and post the results online.The federal government is allocating the tests to states based on their population, rather than helping them develop a strategy based on the size and severity of their outbreaks.“That’s just lazy” said Dr. Michael Mina of Harvard University. “Most states won’t have the expertise to figure out how to use these most appropriately.”Instead, Mina said the federal government should direct the limited test supplies to key hot spots around the country, driving down infections in the hardest-hit communities. Keeping tighter control would also ensure test results are quickly reported.Johns Hopkins University researcher Gigi Gronvall agrees health officials need to carefully consider where and when to deploy the tests. Eventually, methods for tracking the tests will catch up, she said.“I think having the tools to determine if someone is infectious is a higher priority,” she said.___AP data journalist Nicky Forster contributed to this story___Follow Matthew Perrone on Twitter: @AP_FDAwriter___The Associated Press Health and Science Department receives support from the Howard Hughes Medical Institute’s Department of Science Education.

After issuing previous guidance that encouraged schools to close in areas with high transmission of the coronavirus, the CDC is now emphasizing that schools reopen this fall.The guidance issued on Thursday is in line with a Trump administration priority to reopen schools this fall.“It is critically important for our public health to open schools this fall,” said CDC Director Dr. Robert R. Redfield. “The CDC resources released today will help parents, teachers and administrators make practical, safety-focused decisions as this school year begins. I know this has been a difficult time for our Nation’s families. School closures have disrupted normal ways of life for children and parents, and they have had negative health consequences on our youth. CDC is prepared to work with K-12 schools to safely reopen while protecting the most vulnerable.”Now in areas with, as the CDC calls it, "substantial, uncontrolled transmission" of the coronavirus, "Schools should work closely with local health officials to make decisions on whether to maintain school operations. The health, safety, and wellbeing of students, teachers, staff and their families is the most important consideration in determining whether school closure is a necessary step. Communities can support schools staying open by implementing strategies that decrease a community’s level of transmission. However, if community transmission levels cannot be decreased, school closure is an important consideration."In areas with substantial, controlled transmission, "Significant mitigation strategies are necessary." In addition, social distancing and face covering policies should be implemented, the CDC said.Previous guidance called for schools in areas with substantial community transmission (the CDC did not distinguish between uncontrolled or controlled) to, "Implement extended school dismissals (e.g., dismissals for longer than two weeks). This longer-term, and likely broader-reaching, dismissal strategy is intended to slow transmission rates of COVID-19 in the community. During extended school dismissals, also cancel extracurricular group activities, school-based afterschool programs, and large events."In previous guidance, the CDC called on schools to keep students 6 feet apart. But many classrooms do not have the space to properly socially distance students. The Trump administration’s response appears to be a 5 billion request to Congress. President Donald Trump said that the funds, in part, could be used for schools to open additional spaces and hire additional staff in order to help space students.The CDC said that the “best available evidence from countries that have opened schools indicates that COVID-19 poses low risks to school-aged children, at least in areas with low community transmission, and suggests that children are unlikely to be major drivers of the spread of the virus.”But that guidance contradicts a South Korean study published by the CDC earlier this week.The study said that while children under age 9 were less likely to spread the virus, youth ages 10 through 19 were just as likely as adults of spreading the virus.The study also found that closing schools in several Chinese cities, including Wuhan, that school closures and social distancing significantly reduced the rate of COVID-19 among contacts of school-aged children.“The role of household transmission of SARS-CoV-2 amid reopening of schools and loosening of social distancing underscores the need for a time-sensitive epidemiologic study to guide public health policy,” the researchers wrote.In its new guidance, the CDC said that extended school closures are harmful to children and can lead to severe learning loss, and the need for in-person instruction is particularly important for students with heightened behavioral needs.The American Federation of Teachers this week pointed toward a three-point plan that the US should implement for reopening schools.“Our plan details three conditions essential for schools to reopen,” wrote Randi Weingarten, president of the American Federation of Teachers. “First, the average daily community infection rate among those tested for the coronavirus must be very low. (New York Gov. Andrew Cuomo has required the rate not to exceed 5 percent for at least 14 days.) Second, schools must employ public health protocols, including 6-feet social distancing, masks, deep cleaning and handwashing stations. Third, adequate resources must be available to enact these safeguards, including funding for additional nurses, guidance counselors and teachers to reduce class size.”But the CDC also weighed the concerns of the coronavirus against providing physical activity, food and safety for students. The CDC said studies project that the childhood obesity rate would increase by 2.4% if schools remained closed through December.This guidance comes as cases in the US steadily increased earlier this month, prompting coronavirus death counts to rise in recent days. The US had back to back days of more than 1,000 people reportedly dying from coronavirus-related illnesses, according to Johns Hopkins University.To read the CDC’s latest guidance, click here. 5184

After asking for coronavirus-related deadline extensions in April, the Trump administration now appears to be abandoning that request by asking Congress for extra funding to wrap up the 2020 census “as quickly, and safely as possible” in a move that could help ensure the number-crunching for redrawing congressional districts takes place on President Donald Trump’s watch.Census Bureau officials had warned as recently as early July that it was already too late to have the numbers ready without an extension. And outside experts predicted Tuesday that speeding up the timetable would lead to an inaccurate head count that misses people in hard-to-count minority communities.“It would be like giving an expectant mother in the early stages of pregnancy a lot of money to have the baby in 4.5 months,” said John Thompson, a former Census Bureau director in the Obama administration.The Census Bureau is in the middle of the 2020 census, and some of the bureau’s 500,000 door-knockers started heading out this month to households that haven’t yet answered the questionnaire.With the new coronavirus disrupting census operations in April, the Trump administration asked Congress to extend the deadlines required for the U.S. Census Bureau to turn in the head count data used for redrawing congressional district and legislative districts. The Census Bureau also postponed finishing field operations for the 2020 census from the end of July to the end of October.The Democratic-controlled House agreed to the extensions as part of coronavirus-relief legislation, but the Republican-controlled Senate has yet to do so. Senate Republicans on Monday instead proposed an additional 8 million in funding for the 2020 census in its coronavirus-relief bill.“This funding would allow for additional hiring, staffing resources, and replenished contingency funding to provide schedule flexibility as the Census Bureau conducts its largest field operation, nonresponse followup,” the Census Bureau said Monday on its website. “This flexibility is critical to helping the Census Bureau operate in the midst of unprecedented public health crisis, including trying to wrap up field data collection as quickly, and safely as possible, while ensuring a complete and accurate count. “When asked about the status of the deadlines request, the office of Senate Majority Leader Mitch McConnell referred to existing policy for the census timeline and said it had nothing further to add.Historically, the Census Bureau is required to turn over numbers for apportionment, the process of divvying up congressional seats, by Dec. 31, and the numbers used for redrawing legislative districts by March 30. The deadline extensions would push back the apportionment deadline to April 30 and the redistricting deadline for state and local districts to July 31.If the deadline extension for the apportionment numbers is granted by Congress, there’s a chance the final months of the data-crunching would take place under a new administration if presumptive Democratic presidential nominee Joe Biden defeats Trump, a Republican, in the November election.Wary of what they see as Trump’s attempts to politicize the 2020 census, House Democrats say Senate Republicans should approve the request for deadline extensions.“Otherwise, American taxpayers would be forced to pay for the most expensive and potentially least accurate census in our nation’s history,” said U.S. Rep. Carolyn Maloney, a Democrat from New York who chairs the House Committee on Oversight and Reform.Earlier this month, House Democrats asked U.S. Commerce Secretary Wilbur Ross to withdraw two appointees from top positions at the U.S. Census Bureau, claiming they represented the latest effort by the Trump administration to politicize the 2020 census.Then last week, Trump issued a memorandum seeking to exclude people in the country illegally from being included during the process for redrawing congressional districts. Civil rights group have filed multiple lawsuits challenging the memorandum as unconstitutional and an attempt to limit the power of Latinos and immigrants of color. Two more lawsuits were filed Tuesday, including one by California Attorney General Xavier Becerra and several California cities, which said California stood to lose a congressional seat if Trump’s order succeeds.“The timing of the executive memorandum issued last week coupled with what now appears to be abandonment of the request to push back the reporting deadlines clearly suggests that the White House wants to ensure that the president receives the numbers for apportionment while he is still in office. It’s hard to draw any other conclusions,” said Terri Ann Lowenthal, a census expert who worked on census issues as a congressional aide.More than 62% of households had responded to the census as of Sunday, leaving about 55 million households that will require visits by census takers. A Pew Research Center survey taken in June highlights the difficulties already facing census takers, with 40% of adults who say they have not yet responded to the census answering that they wouldn’t be willing to open their door for a census taker.The Census Bureau said Monday that it will start sending out emails to residents in neighborhoods with low response rates, encouraging them to fill out the questionnaire.Talking to reporters at the beginning of the month, Al Fontenot, the bureau’s associate director for decennial programs, said the bureau was “past the window of being able to get those counts” by the end of the year.Kenneth Prewitt, who served as a Census Bureau director in the Clinton administration, said an accelerated census in the middle of a pandemic “can only be explained politically.”“I believe the odds of being able to produce the census between now and the end of the year is extremely low. COVID is in charge. The Census Bureau is not in charge,” Prewitt said. “To finish the census by the end of the year, COVID has got to go away, and it’s not.”___AP Congressional Correspondent Lisa Mascaro in Washington contributed to this report.___Follow Mike Schneider on Twitter at https://twitter.com/MikeSchneiderAP 6170
