IMPERIAL BEACH, Calif. (KGTV) — A new initiative between California and Mexico officials could pave the way for solving the persistent issue of sewage flowing from Tijuana to the U.S.The sewage comes as runoff from the Tijuana River or as flow from the Punta Bandera treatment plant, leading to beach closures in Imperial Beach and Coronado. On Friday, officials from California and Mexico met in Imperial Beach to launch the California-Mexico Strategic Dialogue. The inaugural issue is to find solutions to stop the sewage from flowing into the U.S."While other leaders may use the border as an opportunity to distract and divide, we want to use this as an opportunity to convene and advance," said State Assemblyman Todd Gloria, a Democrat. Officials are reporting progress. Tijuana Councilman Manny Rodriguez said he and others just requested 300 million pesos, or about million dollars, to improve processing tanks at Punta Bandera."We need to focus more on treatment, and if we get the money for that, I think this problem can be fixed," Rodriguez said. Imperial Beach Mayor Serge Dedina said the International Boundary and Water Commission is installing an Earthen Dam in the Tijuana River channel to stop any accidental flows during the dry time of year. "That's a really good sign of little things that don't cost taxpayers any money that keep our beaches clean," Dedina said, adding that those kinds of short-term fixes should be a major part of the dialogue. 1480

How accurate are the coronavirus tests used in the U.S.?Months into the outbreak, no one really knows how well many of the screening tests work, and experts at top medical centers say it is time to do the studies to find out.When the new virus began spreading, the Food and Drug Administration used its emergency powers to OK scores of quickly devised tests, based mainly on a small number of lab studies showing they could successfully detect the virus.That’s very different from the large patient studies that can take weeks or months, which experts say are needed to provide a true sense of testing accuracy.The FDA’s speedy response came after it was initially criticized for delaying the launch of new tests during a crisis and after the Centers for Disease Control and Prevention stumbled in getting its own test out to states.But with the U.S. outbreak nearly certain to stretch on for months or even years, some experts want the FDA to demand better evidence of the tests’ accuracy so doctors know how many infections might be missed.There have been more than 2 million confirmed coronavirus cases in the U.S. and more than 115,000 deaths, according to data compiled by Johns Hopkins University. Cases in nearly half of U.S. states are rising.In recent weeks, preliminary findings have flagged potential problems with some COVID-19 tests, including one used daily at the White House. Faulty tests could leave many thousands of Americans with the incorrect assumption that they are virus-free, contributing to new flare-ups of the disease as communities reopen.“In the beginning, the FDA was under a lot of pressure to get these tests onto the marketplace,” said Dr. Steven Woloshin of Dartmouth College, who wrote about the issue in the New England Journal of Medicine last week. “But now that there are plenty of tests out there, it’s time for them to raise the bar.”The FDA said in a statement that it has already asked multiple test makers to do follow-up accuracy studies, although it didn’t say for how many of the more than 110 authorized screening tests. The agency also said it is tracking reports of problems. Accuracy has also been an issue with blood tests that look for signs of past infections.No screening test is 100% accurate. So details on accuracy are routinely provided for tests of all types, including seasonal flu, hepatitis, HIV and cancers. For example, rapid flu tests are known to miss 20% or more of all cases, a factor doctors weigh when treating patients who have symptoms but test negative.For now, most COVID-19 tests in the U.S. don’t give data on real-world performance, including how often the tests falsely clear patients of infection or falsely detect the virus. That information is lacking for all but a few of the roughly 80 commercial screening tests available, according to an Associated Press review.The government’s emergency authorization process “requires a lower level of evidence,” the agency said. Makers need only show that a test “may be effective” instead of the usual requirement to demonstrate “safety and effectiveness.” They would have to meet that higher threshold once the U.S. government declares the emergency over.Many of the commercial test makers submitted results from 60 samples, the minimum number required and mostly used lab-produced specimens of the virus. The FDA now recommends the use of nasal swabs or other real samples from people screened for coronavirus.Experts say larger patient studies patients are needed to assess a test’s true performance.Lab testing bears little resemblance to actual — sometimes imperfect — conditions at hospitals, clinics and testing sites noted Dr. Robert Kaplan of Stanford University.“You’re testing people in parking lots, the patients themselves are extremely anxious and often unable to follow instructions,” said Kaplan, a former associate director of the National Institutes of Health.Kaplan and others say those differences could explain why some tests are not performing as expected.Last month, the FDA warned doctors of a potential accuracy problem with Abbott Laboratories’ rapid ID Now test, which delivers results in roughly 15 minutes. The test has been lauded by President Donald Trump and used to screen the president, his staff and visitors to the White House.The FDA alert followed a preliminary report by New York University that found Abbott’s test missed between a third to one-half of infections caught by a rival test in patients screened for the virus.Abbott rejected the findings, saying the researchers did not follow the instructions for using its test. The company pointed to alternate patient studies, including its own, that have found the test successfully detects between 91% and 95% or more of virus cases when compared to other tests.But similar problems with ID NOW’s accuracy have been flagged in preliminary reports by researchers at Stanford University, Loyola University and the Cleveland Clinic.For now, the FDA is requiring Abbott to conduct follow-up studies in several different patient groups.The FDA’s emergency standards “are still high but there is a significant difference in the body of work that what would go into a submission under the normal process,” said Abbott vice president John Hackett. “Our normal process takes years to bring these out.”Requiring bigger studies of all coronavirus tests could provide valuable information, but it could also strain the FDA’s already stretched staff and resources, said Dr. Daniel Schultz, former director of the FDA’s medical device center.Dr. Colin West of the Mayo Clinic worries doctors and patients have put too much confidence in the current crop of tests, when an unknown number of patients with COVID-19 are likely receiving false negative results.Even a modest error rate can have grave consequences during an outbreak like COVID-19. West gives the example of a test that is 95% accurate at detecting the virus and is used on 1 million people. That would still result in 50,000 people being incorrectly told that they don’t have the virus.“The negative test does not mean that I’m off the hook,” West said. “We just need to maintain that level of vigilance until we have a better sense of how good these tests really can be.”___Follow Matthew Perrone on Twitter: @AP_FDAwriter.___Follow AP pandemic coverage at http://apnews.com/VirusOutbreak and https://apnews.com/UnderstandingtheOutbreak.___The Associated Press Health and Science Department receives support from the Howard Hughes Medical Institute’s Department of Science Education.

Hundreds of flights were canceled and 14 million people were under a blizzard warning Sunday as a storm brought snow, wind and rain to large stretches of the Midwest.Kansas Gov. Jeff Colyer issued a state of emergency declaration for the state.Kansas City International Airport was closed to flights arriving on the airfield due to low visibility caused by weather conditions and limited visibility under a quarter-mile, according to an airport tweet.The Kansas Division of Emergency Management's Twitter page said the declaration "authorizes the use of state resources and personnel to assist with response and recovery operations in affected counties.""We strongly recommend that you postpone travel plans, if possible; however, if you must be on the road, make sure your vehicle's emergency kit is stocked, your gas tank is full and your cell phone and charger are with you and someone knows your travel plans," the declaration reads.Multiple roads are closed across the state due to whiteout conditions, according to the KanDrive website.The weather system was forecast to move into the Great Lakes region before hitting the Northeast on Monday, according to CNN meteorologist Haley Brink.Due to the addition of Cook County, Illinois, the number of people under blizzard warnings jumped from 8 million to 14 million. The National Weather Service office in Chicago said the worst will come late Sunday.Nearly 20 million people were under a high-wind advisory. This includes residents of Kansas and some in parts of Missouri, Nebraska and Iowa.Fort Hays State University student Brooks Barber captured the blizzard conditions in Hays, Kansas, on Sunday morning. Streets were dark, and many were without power, he said.The National Weather Service's Topeka office posted a video of near-blizzard conditions.Whiteout conditions brought low visibility to the small town of Chariton, Iowa, which is an hour south of Des Moines.The region could see whiteouts and slick roads throughout Sunday, making travel difficult if not impossible at times, Brink said."It's pretty treacherous travel conditions," she said.Forecasts say snowfall totals of 6 to 10 inches are possible across the Midwest. Some areas could receive as much as a foot of snow within the next 24 to 36 hours.By Monday, Brink said, the storm will have moved into the Northeast. Parts of New England could see snow, while cities along the coast are forecast to receive heavy rain.Also, 17 million people are under wind advisories. Sustained winds of between 30 and 45 mph are anticipated, with the possibility of 65 mph gusts.The storm's impacts have been felt already by travelers on the final days of the Thanksgiving holiday rush. Nearly 1,000 US flights had been canceled by late afternoon Sunday, with delays to 3,100 flights, according to flight-tracking website FlightAware. Most were at Chicago's O'Hare International and Midway airports.And an approximately 60-mile stretch of Interstate 70 in Kansas has been closed, according to a tweet from the state's Department of Transportation, from WaKeeney to Russell. 3089
