The destructive storm surge has receded, and the clean up has begun from Hurricane Laura in Texas and Louisiana. But officials along this shattered stretch of Louisiana coast are warning returning residents they will face weeks without power or water amid the hot, stifling days of late summer. Hundreds of thousands of people in two of the hardest-hit states are reported to be without power following the severe storm.The U.S. toll from the Category 4 hurricane stood at 16 deaths, with more than half of those killed by carbon monoxide poisoning from the unsafe operation of generators. President Donald Trump landed in Louisiana Saturday afternoon to tour the damage in Louisiana and will head to Texas next. 720

The CDC is recommending Americans not travel for Thanksgiving during the current spike in coronavirus cases nationwide.“As cases continue to increase rapidly across the United States, the safest way to celebrate Thanksgiving is to celebrate at home with the people you live with,” the Centers for Disease Control and Prevention website reads. “Travel may increase your chance of getting and spreading COVID-19. Postponing travel and staying home is the best way to protect yourself and others this year.”This is the strongest urging from the health agency, which is part of the Health and Human Services Department, asking Americans to take stricter precautions to slow the spread of the coronavirus.There are more than 11 million reported cases of COVID-19 in this country since the pandemic started, and more than 250,000 Americans have died."We're seeing exponential growth in cases," CDC COVID-19 incident manager Dr. Henry Walke said during a press briefing. "The opportunity to translocate disease or infection from one part of the country to another leads to our recommendation to avoid travel at this time."If people are still planning to travel for the Thanksgiving holiday, the CDC has a series of questions on their website for travelers and family members to consider before going ahead with travel plans.Questions include: Are you, someone in your household, or someone you will be visiting at increased risk for getting very sick from COVID-19? Are cases high or increasing in your community or your destination? Are hospitals in your community or your destination overwhelmed with patients who have COVID-19? Do your plans include traveling by bus, train, or air which might make staying 6 feet apart difficult?“We understand that people want to see their family and relatives and do it as they’ve always done it. But this year we’re asking them to limit their travel," Dr. Walke said. The CDC also recommends those who travel to follow all of their guidance for slowing the spread of coronavirus: wear a mask, wash hands, social distance, get the flu shot, and bring extra masks and hand sanitizer.Whether or not there is travel involved, the CDC also recommends some safety precautions when celebrating Thanksgiving with a group of people.These include bringing individual utensils, plates and cups to reduce sharing, wear a mask when around people not in your household - even indoors, use single-use options when possible to reduce sharing.Consider eating outside and limit the number of guests, the CDC says. Also, clean and disinfect touched surfaces between use. If indoors, open windows and doors to allow ventilation.“Celebrating virtually or with the people you live with is the safest choice this Thanksgiving,” the CDC states. 2761

The drop in gun sales has lead to deep job cuts at Sturm RugerOn Wednesday, the company reported a 21% sales decline for 2017. Thursday it disclosed that it has cut 700 jobs, or more than a quarter of its staff, over the last 13 months. That leaves it with 1,750 workers."When we reduced production in 2017, we had to make some difficult decisions," said CEO Chris Killoy, on a call with analysts Thursday. Many of the jobs were eliminated through attrition. The company also had 320 temporary employees a year ago who have since left the company. In January, the company needed to further reduce staff, prompting it to lay off an additional 60 workers.Gun sales have been sharply lower across the industry since President Donald Trump was elected. Fears that Hillary Clinton would win the presidency and seek tougher gun control laws drove record sales through 2016, and encouraged retailers to stock up on inventory. With the election of Trump and Republicans in control of both houses of Congress, those fears greatly abated.Killoy said that 2017 FBI background checks, which correspond roughly to purchases, fell 11%. Retailers also cut back on purchases to reduce inventory."2017 was a challenging year for the firearm industry," Killoy. But he said as a result of the job cuts, "we're better positioned to compete in 2018."There has been more talk about gun control in the week since the shooting of 17 students and staff at a Florida high school, led by many of the students and families from that school.President Trump and some Republicans, including Senator Marco Rubio of Florida, have voiced new support for some gun control measures. But it's too soon to say whether those efforts will affect gun sales.Killoy did not mention the gun control debate during his conference call, although he did express sympathy for victims of the Florida shooting."Like all Americans, we struggle with the shock and sadness of these terrible events," he said.Sturm Ruger is not the only company to report a drop in sales. Overall the industry has reported a sales decline of more than 0 million in 2017.Gun maker Remington has warned it plans to file for bankruptcy protection soon. Killoy was asked about whether Sturm Ruger would be interested in buying Remington, given that it has a strong balance sheet. Ruger's cash on hand fell by nearly million during the year, but it still has .5 million and no debt. He wouldn't rule out a deal for Remington, but wouldn't comment on it directly."We're watching that closely," he said the coming bankruptcy case. "We wish them well going through that process. With million cash on hand, it may provide some opportunities down the road." 2727

The CDC announced Friday a pilot project intended on decreasing chronic diseases in high-risk communities. The government is putting million toward the project to address five areas of social detriments.Some groups—including racial and ethnic minorities, those living in poverty, and people in certain parts of the country—are disproportionately impacted by the burden of chronic conditions, the CDC said.“Chronic diseases touch every American, in one way or another,” said Karen Hacker, M.D., M.P.H., director of CDC’s NCCDPHP. “This important pilot project will help us better understand strategies to advance health equity and reduce the immense burden of chronic disease.”The program will address five areas on concern, said the CDC:Built environment: human-made surroundings that influence overall community health and individual behaviors that drive healthCommunity-clinical linkages: connections made among health care systems and services, public health agencies, and community-based organizations to improve population healthFood insecurity: an economic and social condition characterized by limited or uncertain access to adequate and nutritious foodSocial connectedness: the degree to which individuals or groups of individuals have and perceive a desired number, quality, and diversity of relationships that create a sense of belonging and being cared for, valued, and supportedTobacco-free policy: population-based preventive measures to reduce tobacco use and tobacco-related morbidity and mortality.The CDC said it will work with the Association of State and Territorial Health Officials and the National Association of County and City Health Officials to identify community to join the pilot program. 1727
