The coronavirus pandemic may have started earlier than previously thought, according to scientists from the CDC.A study from government scientists published November 30 appears to confirm what some health experts have suggested, patients infected with COVID-19 were in the US before the beginning of 2020.“The findings of this report suggest that SARS-CoV-2 infections may have been present in the U.S. in December 2019, earlier than previously recognized. These findings also highlight the value of blood donations as a source for conducting SARS-CoV-2 surveillance studies,” the report states.The first officially documented case of COVID-19 in the US was reported on January 19, a person who had returned to the US after traveling from China.The World Health Organization was alerted to the novel coronavirus by officials in Wuhan, China on December 31, 2019. The CDC researchers say further reports have identified a patient in Wuhan with COVID-19 symptoms as early as December 1, 2019.The study looked at more than 7,000 routine blood donation samples taken by the American Red Cross from people in nine states between December 13, 2019 and January 17, 2020.They found COVID-19 antibodies in 106 samples, mostly from the states of California, Oregon and Washington, from blood collected between December 13-16, 2019. Other samples that indicated COVID-19 antibodies were from Connecticut, Iowa, Massachusetts, Michigan, Rhode Island, and Wisconsin taken in early January 2020.“The presence of these serum antibodies indicate that isolated SARS-CoV-2 infections may have occurred in the western portion of the United States earlier than previously recognized or that a small portion of the population may have pre-existing antibodies that bind SARS-CoV-2,” the report states.Scientists acknowledge that patients presenting with what is now known as COVID-19 symptoms before mid-January would likely not have had clinical samples taken or kept because of how new the virus was. Therefore, the CDC used the existing repository collected by the American Red Cross during their routine blood donation process.“These specimens were previously archived for potential future studies to identify emerging transfusion-transmissible infections but were re-purposed for the present study,” researchers stated.Researchers caution that these results are subject to limitations. Although they detected antibodies, that does not mean they are “true positive” COVID-19 tests. In order to get a true positive, a different test would need to be a run. 2545

The Department of Homeland Security and the Pentagon are having initial discussions that could lead to a 45-day extension of the southern border mission for US troops, according to two administration officials.DHS would have to make a specific request to the Pentagon. Under the current plan, the border mission is scheduled to end December 15.The discussion comes following tensions at the border Sunday, when about?500 migrants overwhelmed police blockades on the Mexican side of the San Ysidro port of entry, two journalists in Tijuana told CNN. US authorities used tear gas to disperse the crowds, which included families and small children, and more than 100 migrants were arrested.One of the officials said that "based on what happened on Sunday" DHS still wants the help of the Defense Department, adding that "the threat has not gone away."The agencies are also discussing whether some engineers who worked on fortifying crossing points in Arizona and Texas can now be sent home and whether more troops will shift to California.President Donald Trump sent about 5,800 federal troops to the border after spending the weeks leading up to the midterm elections decrying a procession of migrants that was still thousands of miles from the US border. Last week, Trump granted the troops new powers to aid in "crowd control, temporary detention and cursory search" while protecting Customs and Border Protection personnel from the migrants, should they engage in violence.On Wednesday afternoon, Secretary of Defense James Mattis said the Pentagon was ready to "react to the Department of Homeland Security" if it asks for any extensions. Mattis added, "Right now we have no new requests, although we are discussing every day the situation and so I can't forecast when that will be."Last week Homeland Secretary Kirstjen Nielsen said she had "no doubt that DoD will continue to be our partners in this mission until it is resolved."NPR was first to report the possible extension. 2004

The family flick "Show Dogs" is getting an immediate re-cut after parents who took their children to see the movie criticized scenes they say depict sexual abuse.The edits address scenes in which the lead undercover police dog Max, voiced by Ludacris, who while being inspected at a dog show becomes comfortable with his private parts being touched, according to Deadline.In a statement, Global Road Entertainment said the revised version of the film will be in theaters this weekend:  508

The Georgia Democratic Party and gubernatorial candidate Stacey Abrams' campaign filed a lawsuit in federal court Sunday asking for rejected absentee ballots and provisional ballots to be counted in the Georgia governor's race.The lawsuit challenges the rejection of more than 1,000 absentee ballots for missing information or mismatching information, like birth dates or addresses.The lawsuit also seeks relief for voters whose provisional ballots were rejected in Gwinnett and Dekalb counties, which are in the Atlanta metro area, because they are registered in a different county.CNN has not projected a winner in the race.Republican candidate Brian Kemp currently leads Abrams with 50.3% of the vote. If Kemp's share dips below 50%, the race automatically goes into a run-off on December 4, even if Kemp is the top vote-getter. For now, Kemp's lead stands at nearly 59,000 votes. 891

The death of Brent Taylor -- the North Ogden, Utah, mayor and soldier who was killed Saturday in Afghanistan -- reverberated far beyond his small city in northern Utah.People around the country are mourning the loss of the National Guardsman who was finishing up his latest tour of duty in the war-torn country when he was killed in a so-called "insider" attack.But despite the grief, many are finding hope in the final message Taylor posted to Facebook, just days before he died."As the USA gets ready to vote in our own election (Tuesday), I hope everyone back home exercises their precious right to vote," Taylor wrote in the post. "And that whether the Republicans or the Democrats win, that we all remember that we have far more as Americans that unites us than divides us. 'United we stand, divided we fall.' God Bless America." 842
