The Centers for Disease Control and Prevention have changed its definition of a “close contact,” which impacts the agency’s recommendation on who should quarantine amid the coronavirus pandemic.Previously, the CDC recommended that those who were within 6 feet for 15 minutes of someone infected with the coronavirus should quarantine for two weeks. Now, the CDC recommends that those who are in contact with someone infected for 15 minutes over a 24-hour period should quarantine.The CDC offers the following recommendations for those who have been in contact with someone recently infected with the coronavirus:Stay away from others, especially people who are at higher risk for getting very sick from COVID-19, such as older adults and people with other medical conditions, if possible.If you have been around someone with COVID-19, stay home and away from others for 14 days (self-quarantine) after your last contact with that person and monitor your health.If you have a fever, cough or other symptoms of COVID-19, stay home and away from others (except to get medical care or testing, if recommended).If you need support or assistance while in self-quarantine, your health department or community organizations may be able to provide assistance. 1258

The flu vaccine may have an important benefit beyond protecting against influenza: It may also prevent heart attacks, especially in those at high risk, experts say."It's been a long time that people have recognized that association with flu season and development of a heart attack," said Dr. Kevin Schwartz, an infectious disease physician at Public Health Ontario.When it comes to preventing heart attacks in people with cardiovascular problems, experts have put getting the flu vaccine on par with long-term measures such as quitting smoking or taking one's medication for high blood pressure.  610

The Department of Homeland Security formally requested that the Pentagon extend the deployment of active-duty troops on the southern border Friday, potentially extending their deployment 45 days beyond the original deadline of December 15."Given the ongoing threat at our Southern border -- today the Department of Homeland Security submitted a request for assistance to the Department of Defense to extend its support through January 31, 2019," Department of Homeland Security spokeswoman Katie Waldman told CNN in a statement."This request refines support to ensure it remains aligned with the current situation, the nature of the mission, and (Customs and Border Protection) operational requirements," she added.The Pentagon confirmed receipt of the request but said Secretary of Defense James Mattis had yet to sign off on it:"We have received the Request for Assistance from the Department of Homeland Security, it is with the Secretary (of Defense) for consideration."There are currently some 5,600 troops at the border, divided among Texas, California and Arizona.President Donald Trump sent the troops 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.Defense officials have suggested that some of the troops, primarily engineers involved in enhancing infrastructure at points of entry, could be drawn down in the relative near term as those tasks are completed.Two officials tell CNN that the number of trumps assigned to the mission is likely to drop to 4,000 as a result.Other functions, including helicopter support to help move Customs and Border Protection personnel to different areas along the border, are likely to continue.The deployment's extension means the Pentagon's initial cost estimate of million for the border deployment is likely to increase as that estimate was based on the mission ending on December 15. 2175

The Girl Scouts of the USA have appointed their first-ever Black CEO.On Monday, Judith Batty took over as Interim CEO after Sylvia Acevedo, who was with the Girl Scouts for four years, stepped down on Aug. 10. Acevedo's last day with the organization was Saturday."When I was young, the Girl Scouts instilled in me the courage, confidence, and character that have guided me through my life and career. It is an incredible honor to bring those lessons back full circle to help the Girl Scouts navigate this transition," said Judith Batty, interim CEO of GSUSA in the press release. "As families across the country contend with so much uncertainty and upheaval, I am committed to ensuring that the Girl Scouts continues to offer shelter in the storm - a place where all our girls feel welcome can find community, solidarity, leadership opportunities and fun, despite the challenging moment we are all collectively living through."Batty began in the organization as a Brownie with the Nassau County Council in New York. She continued scouting over the years, later serving two terms on the National Board. Per CNN, Batty served for nearly 30 years as both a corporate executive and senior legal counsel for ExxonMobil.While at ExxonMobil, she became the first woman and first Black General Counsel of the affiliate in Japan, CNN reported. 1343

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
