As the Summer of COVID draws to a close, many experts fear an even bleaker fall and suggest that American families should start planning for Thanksgiving by Zoom.Because of the many uncertainties, public health scientists say it’s easier to forecast the weather on Thanksgiving Day than to predict how the U.S. coronavirus crisis will play out this autumn. But school reopenings, holiday travel and more indoor activity because of colder weather could all separately increase transmission of the virus and combine in ways that could multiply the threat, they say.Here’s one way it could go: As more schools open for in-person instruction and more college students return to campuses, small clusters of cases could widen into outbreaks in late September. Public fatigue over mask rules and other restrictions could stymie efforts to slow these infections.A few weeks later, widening outbreaks could start to strain hospitals. If a bad flu season peaks in October, as happened in 2009, the pressure on the health care system could result in higher daily death tolls from the coronavirus. Dr. Robert Redfield, director of the Centers for Disease Control and Prevention, has said that scenario is his biggest fear.One certainty is that the virus will still be around, said Jarad Niemi, a disease-modeling expert at Iowa State University.“We will not have a vaccine yet and we will not have enough infected individuals for herd immunity to be helpful,” Niemi said.Fall may feel like a roller coaster of stop-and-start restrictions, as communities react to climbing hospital cases, said University of Texas disease modeler Lauren Ancel Meyers. Everyone should get a flu shot, she said, because if flu spreads widely, hospitals will begin to buckle and “that will compound the threat of COVID.”“The decisions we make today will fundamentally impact the safety and feasibility of what we can do next month and by Thanksgiving,” Meyers said.The virus is blamed for over 180,000 deaths and 6 million confirmed infections in the U.S. Worldwide, the death toll is put at almost 850,000, with over 25 million cases.The U.S. is recording on average about 900 deaths a day from COVID-19, and newly confirmed infections per day are running at about 42,000, down from their peak in mid-July, when cases were topping out at over 70,000.Around the country, a chicken processing plant in California will close this week for deep cleaning after nearly 400 workers got sick, including eight who died. And college campuses have been hit by outbreaks involving hundreds of students, blamed in some cases on too much partying. Schools including the University of North Carolina, Michigan State and Notre Dame have moved instruction online because of clusters on their campuses.Several vaccines are in advanced testing, and researchers hope to have results later this year. But even if a vaccine is declared safe and effective by year’s end, as some expect, there won’t be enough for everyone who wants it right away.Several companies are developing rapid, at-home tests, which conceivably could be used by families before a Thanksgiving gathering, but none has yet won approval.More than 90 million adults are over 65 or have health problems, putting them in higher danger of severe consequences if they get sick with the coronavirus. Many of them and their families are starting to decide whether to book holiday flights.Cassie Docking, 44, an urgent care nurse in Seattle, is telling her parents — both cancer survivors — that Thanksgiving will be by FaceTime only.“We all want to get to 2021,” she said, “and if that’s what it takes, that’s what we’ll do.”Caitlin Joyce’s family is forging ahead with a holiday feast. They plan to set up plywood tables on sawhorses in a large garage so they can sit 6 feet apart.“We’ll be in our coats and our sweaters,” said Joyce, 30, of Edmonds, Washington, who plans to travel to her grandparents’ home in Virginia. “It will be almost like camping.”One widely cited disease model projects 2,086 U.S. deaths per day by Thanksgiving, more than double compared with today.“In our family we will not have our extended family get-together. We will stick to the nuclear family,” said Dr. Christopher Murray of the Institute for Health Metrics and Evaluation, one of the few models making a prediction for November.Uncertainty is huge in Murray’s model: Daily deaths could be as low as 1,500 by Thanksgiving or as high as 3,100. In a more optimistic scenario, daily deaths could range from 510 to 1,200 if nearly everyone wears masks. A more pessimistic scenario? From 2,700 to 6,500 daily deaths if social distancing rules continue to be lifted and are not reimposed.With all the uncertainty, most disease modelers aren’t looking that far ahead — at least officially.Jeffrey Shaman, a public health expert at Columbia University, thinks the virus will spread more easily as the weather forces people indoors: “But what level of a bump? That’s hard to say.”At Carnegie Mellon University in Pittsburgh, computer scientist Roni Rosenfeld’s team uses machine learning to project COVID-19 deaths. The team’s computer algorithm learns from patterns it finds in state and county data to improve its forecasts.A five-time winner of a CDC competition for predicting flu season activity, Rosenfeld thinks his model’s COVID-19 projections aren’t very useful beyond four weeks because of the wild card of human behavior, including that of government officials.“What happens very much depends on us,” he said. “People, myself included, don’t always behave rationally.” Presented with the same facts, “the same person might behave differently depending on how sick and tired they are of the situation.”Like other disease modelers, Rosenfeld said the virus will still be with us at Thanksgiving, readily spreading at family gatherings. While his plans may yet change, he said he is going to travel with his wife to visit their adult children. They will wear masks and keep a safe distance during the visit.___The Associated Press Health and Science Department receives support from the Howard Hughes Medical Institute’s Department of Science Education.

As people prepare to travel for Christmas, experts are concerned about another spike in coronavirus cases.We are almost a month out from Thanksgiving, and according to the COVID Tracking Project, more than 47,000 people in the U.S. have died from COVID-19 since Thanksgiving.And although the CDC advised against traveling, the Transportation Security Administration screened 9.5 million travelers during the 10-day Thanksgiving travel period.TSA also screened more than 3.2 million people at airports nationwide this past weekend.And as people gear up to spend the Christmas holiday with loved ones, the surge of new COVID-19 cases continues with no end in sight.The Harvard Global Health Institute and Brown School of Public Health created a risk-assessment tool that color-codes states with over 25 new daily cases per 100,000 people. The color red on the map means the state is considered "at a tipping point."According to the Harvard and Brown researchers, the 10 worst states considered to be "at a tipping point" are Tennessee, Rhode Island, California, Alabama, Arizona, Oklahoma, Indiana, Utah, Arkansas, and Delaware.According to Johns Hopkins University data, in Tennessee, the state's positive rate is 19.2%.In Alabama, the state's positive rate is 40.4%. Arkansas's positive rate is 18.7%, Arizona's is 13.1%, Delaware's is 7.7%, 13.3% of COVID tests in California are positive, Oklahoma's positive rate is 21.1%, Indiana has an 11.6% positive rate, Rhode Island is at a 6.3%, and 17.6% of COVID tests in Utah are positive.According to the CDC, between 1.2 million to 2.3 million new cases are likely to be reported in the week ending January 9, 2021. 1671

As states across the country grapple with an increase in coronavirus cases and a huge demand for tests, many businesses are looking for other ways to get more mileage out of their supply chain.Like with anything else, supply and demand is a constant struggle. In this unprecedented era, the demand for things like coronavirus tests is so large that public health departments don't have a choice but to figure out ways to make our supplies last. Several states are examining pooled testing. California's Public Health Department says it's to "better leverage testing resources."Pooling is something that blood banks have used for decades to keep their blood supply safe. Dr. Claudia Cohn is the Chief Medical Officer of the AABB, formerly known as the American Association of Blood Banks.“If you have 100 people that need to be tested and if you test each of them, you’ll do 100 tests. If you find that your test is sensitive enough that you can pool together 20 samples at the same time, instead of having 100 tests, you can have five pools of 20,” Dr. Cohn said.Now, if one of those five pools is positive, then Dr. Cohn says, "You’ll need to break it out and test each of those separately. So, let’s say you have one positive person in a pool of 100 people, you either do 100 tests and find one positive or you do five pools of 20, four of those pools will be negative, so you’ve done 4 pools and covered 80 people."The test works by taking a tiny sample from each person who was tested.“When you take a swab from everyone’s nose, you isolate the DNA from that swab,” Dr. Cohn said about the PCR test, which is generally a nose swab. “It’s not a lot, it’s a small amount but it’s enough. Because these tests are very, very sensitive.”Those tests are so sensitive, and they have to be, that pooling can really only work if the test can handle, as in detect, multiple samples at once. The FDA mandates that.“The FDA is quite demanding as they should be in terms of making sure tests work well and are safe,” Dr. Cohn said.And Dr. Cohn says, pooling wouldn't work in an area where there's a large outbreak, which means a large number of people would test positive regardless of pooling. In the blood world, this strategy has been perfected.“You are taking 100 samples and taking a drop from each sample and putting it together,” Dr. Cohn said. “You are testing every single person who comes through. In the blood world safety is before everything."Blood banks test for HIV, Hepatitis C and B and well as COVID-19 antibodies, according to the American Red Cross. And, as this pandemic moves through our communities, Dr. Cohn says our blood supply needs to remain strong.“After that initial spike, it went down again and that was okay because elective surgery had been canceled, so the demand for blood had gone down as well so for a while we were at a good balance of demand and supply. But then elective surgeries opened up and hospitals went back to full service and we’re in a shortage again,” Dr. Cohn said. 3017

At a quick glance through her office, you might think Laura Packard was working on the campaign trail. But this small business owner is fighting to keep her own title: cancer survivor.“A little over three years ago, I walked into a doctor's office with a nagging cough and walked out with a stage four cancer diagnosis. Everything changed for me all at once,” said Packard.She underwent chemotherapy and radiation over a six-month period. “I lost all my hair. Some days, I wouldn't be able to get out of bed, and there was a lot of pain,” she recalled.After multiple surgeries and hospitalizations, she said her bills were really piling up. “I think it was near a million dollars,” said Packard of her medical bills.She says, thankfully, her insurance through the Affordable Care Act saved her in more ways than one.“I've been self-employed off and on for over a decade, and I used to have junk insurance, and if I still had that insurance today, I would be bankrupt or dead,” said Packard.However, she’s worried this level of insurance coverage won’t last with the recent Supreme Court confirmation and once the election results become final.“The day after my first chemotherapy was when Republicans in the House voted to dismantle the Affordable Care Act, which was keeping me alive,” she said.As talks of repealing the ACA gained ground, she moved hundreds of miles away from family to live in Colorado.“Colorado has pretty good state-level protections, but nobody should have to live like this. Nobody should have to be a health care refugee in their own country just to get care, and state-level protections can only go so far. What you need is a federal law to protect everybody.”She, like so many Americans, is wondering how she will pay for her coverage if her costs go up. Packard is fearful her health will suffer if she can’t afford her premiums.“My life is in the balance, but millions of Americans are in the balance, too.”She is worried those with pre-existing conditions won’t be able to get the care they need at a price they can afford.She is also concerned the individual mandate for health insurance will be taken away. With fewer healthy people paying into the healthcare system, the system cannot help cover costs for people who are sick.“My fear is that the rest of the affordable care act will tumble because we won’t be able to sustain it in its totality,” said Michele Lueck, president of Colorado Health Institute.Packard is just one of millions being helped by the subsidies the Affordable Care Act is founded on, and while she knows the Affordable Care Act could be improved, she hopes it will be the building block for even better care, instead of waiting years for a new solution.“I don't even know how many people will die if they succeed in destroying the Affordable Care Act, because people will lose their insurance and people will die,” said Packard.The struggle is something all Americans have endured this year. This cancer survivor is just hoping this election will bring a confirmation that her health is valued.“In a pandemic, it's more clear than ever that we're all in this together and we need candidates and elected officials that work for the greater good,” said Packard. 3224

As September is NICU Awareness Month, parents of NICU babies are working to serve as a voice for families who are trying to navigate the overwhelming and often terrifying experience of watching your baby in a neonatal intensive care unit, especially during a pandemic.When Andi Petito was 21 weeks pregnant, she went in for a simple and common anatomy scan of her baby.“When she got really quiet and excused herself,” Petito said about a routine appointment. The technician who performed the ultrasound returned with the doctor who said there were some major problems, Petito was sent to the hospital where she would remain on bed rest until she went into labor. Petito gave birth to River at 24 weeks, weighing 1 pound, 7 ounces. River was transferred to the NICU.“They warn you it's a roller coaster and they try to prepare you but you’re not really prepared for the ups and downs,” Petito said.That roller coaster is how they describe the NICU.“Terrifying, stressful and, I mean, we lived on edge,” Petito said. “You almost feel paranoid because you’re so worried about her compromised immune system, comprised lungs. Kind of like we’re all living now, but no one else is joining you in it.”Neonatologist Dr. Melinda Elliott said no one expects, prepares or plans for a NICU stay.“Nobody plans to meet me, nobody plans to meet the doctor who specializes in sick babies,” Elliott said.She said parents should not focus on all of the machines and equipment that surround your newborn.“The best thing you can do is turn the other way and focus on your baby,” Elliott said. “Just look at your baby because that baby is your baby no matter how small or how sick. You’re the only parent that baby has.”Elliott said the pandemic has stripped the visitor policy. Usually, there's only one parent allowed in at a time. While that's hard for already stressed families to manage, she reminds parents to focus on the importance of nutrition and to continue to advocate for your baby.“Probably the biggest piece of advice is just ask questions, keep asking,” Elliott said. “If you don’t get an answer you like, ask again and find somebody else to ask. You deserve to understand what’s going on with your baby:”Now, after 129 days in the NICU, that once tiny little baby is 3 years old, and likes to discuss her favorite color, pink, and all things Paw Patrol. Petito said she got through the NICU by doing her own research, being her own advocate, fighting for what her baby needs and by being honest with herself.“It’s OK to fall apart sometimes,” Petito said. “Parenthood is not what you envision when your child is not able to come home with you and everything has been blown up and so it’s okay if you need to cry and fall apart and pick yourself back up and go to the NICU.”The Petitos have now given River a sibling. Fern is happy and healthy and didn't need the NICU. And while it was never an easy roller coaster ride, they say it made River the strongest little fighter they know. 2987
