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.

At least two sheriff's offices in Florida are investigating after voters in the state say they received threatening messages from people claiming to be affiliated with the Proud Boys that attempt to scare voters into voting for President Donald Trump.According to Florida Today, the emails sent to voters followed a similar format: The sender claimed to be in possession of personal information because they "gained access" to the "entire voting infrastructure." The message then says the voter must "vote for Trump on Election Day or we will come after you."Florida Today reports that the Brevard Supervisor of Elections has reported the messages to local law enforcement. In a Facebook post, the sheriff of Alachua County, located several hours northwest of Brevard County, said it was investigating similar messages with assistance from federal law enforcement. 872

As more and more states legalize marijuana, a Colorado family and Mothers Against Drunk Driving (MADD) want people to know about the devastating consequences of driving while high.Amanda Hill loved all things animal. The 24-year-old had landed a coveted internship at the Denver Zoo and was well on her way to becoming a vet tech.“She was like an animal whisperer,” said Amanda’s mother, Denise Hill. “She loved animals. Animals made her feel better. She didn’t always get along with humans as she did with animals.”The two were extremely close. Denise says on a sunny June day near Denver, Colorado, the two worked in the garage until Amanda had to leave for an appointment.“I’m thankful that when she left, I gave her a hug and told her I loved her,” said Denise.Then, she got a phone call.“I picked the phone up and instead, it was that phone call that every parent dreads,” said the mother.On a road that Amanda travels all the time, and in the middle of the afternoon, she was hit head on.“And the impact was such that the sheriff who showed up later said its typically not survivable at the level they recorded,” Denise said.While the medical staff worked to save her life, they let Ed and Denise Hill have a few moments with their daughter.“We got those precious few seconds to tell her we loved her,” said Denise. “The last thing I told her was you’re going to be okay.”Amanda didn't make it. Two years later, her parents are keeping her memory alive, fighting for tougher laws for people who drive while high on marijuana. They believe the sentence that was handed down to the driver who caused the accident that killed their daughter was too lenient.“There’s so much that’s not understood about driving high, how long it stays in your system, what effect it truly has,” said Denise.Helen Witty, National President of Mothers Against Drunk Driving, said “I think the frightening thing is that almost half of Americans think it's okay to drive after smoking marijuana even in the first two hours.”Witty also lost her 16-year-old daughter in an accident. That driver was also drinking. And had smoked marijuana.“When she died so violently and suddenly, I always would say, my daughter would be saying, mother say something. Do something. Not mom, mother.”A new study sponsored by MADD and dedicated to Amanda Hill found that 26% of people surveyed think that driving after marijuana consumption is "not too concerning" and more than 40% of parents and grandparents reported never discussing the subject.“The legalization happened before the data is out there,” said Witty. “The data is actually that it’s different for every person”Ed and Denise Hill say they are proof of what one decision can do to a family. Amanda's loss is a painful void that they feel every day."The first thing you have to do is decide whether you want to live anymore and if you make the decision to live, then you have to decide how you’re going to live,” said Denise. “Are you going to just get through each day or is there going to be some kind of meaning in your life?”The meaning is in her memory – a life cut too short, a death that was entirely preventable. 3154

As school districts across the country prepare to send kids back to school in-person, many bus drivers are voicing concerns about the potential for COVID-19 to spread on school buses, where oftentimes social distancing is nearly impossible.For the better part of 32 years, Cheryl Merritt has driven a school bus in Hanover, Massachusetts. She has driven in every kind of weather condition imaginable, but this is the first year she’ll be driving a bus during a pandemic.“I just want all the kids on the bus to stay safe and the drivers to stay safe. If we have a driver who gets sick, they’re going to be out for at least 14 days,” she lamented, as she turned her bus onto a side street in a residential New England town.Merritt’s concerns are shared by school bus drivers and districts across the country. Many school bus drivers have retired from other professions, meaning their age makes them more susceptible to catching the virus.“I don’t want this, I don’t. I’m not ready to die,” the 61-year-old Merritt said.School buses are presenting a particularly difficult challenge as districts try to send kids back to the classroom. When fully loaded with kids, most school buses fit about 77 students. Cramming students into a bus though would be a perfect place for COVID-19 to spread, so many states are advising bus companies to have only one student per bench. But taking some bus capacity down to about 12 kids means school districts would need to run double or triple the number of trips each day just to pick every child up.Transportation experts say adding more buses would be nearly impossible given a nationwide bus driver shortage, which existed long before the outbreak.“It doesn’t matter what you’re gonna do with kids once you get them to school, you have to get them there first,” explained David Strong, who works with the School Transportation Association of Massachusetts.Strong’s other concern is that kids won’t adhere to social distancing guidelines or mask-wearing requirements once they get onto a bus.“There’s almost no way to realistically social distance on a bus,” he added.To address concerns about the spread of COVID, many school districts are mandating that school buses keep their windows open year-round to help with the flow of air. Some districts are also adding bus monitors to ensure kids, especially elementary school students, are following new guidelines.As for Merritt, she sees herself and other bus drivers as the first line of defense when it comes to keeping COVID-19 out of the classroom.“When you stop to pick up a child look at them, make sure they don’t look sickly or they’re coughing,” she said. 2655

As the number of COVID-19 cases rapidly increases, you might feel more apprehensive about eating out now.So WFTS took your questions straight to a former health inspector, who believes certain food safety protocols should be followed when you're dining out."I think everyone should be wearing a mask if they're in public," said Danielle Egger, who started her own restaurant consultation company called Florida Food Safety Systems, after being a health inspector for many years.She says since restaurant inspections are public, you should look up past inspections here to see how the restaurant performed before the pandemic hit."If the restaurant has had concerns about sanitation in the past before COVID started, it might be a good idea to consider going elsewhere. And if sanitation issues, handwashing, and cleanliness were an issue before this ever started, chances are they're struggling to get up to compliance now," she explained.When you walk into a restaurant, Egger says employees should be constantly cleaning, especially highly-touched areas."I have been advising them to set timers so that every 30 minutes, they're wiping down high touched areas. That's going to be any of the door handles, any of the points of sale systems that they're using to complete transactions," she said.And that includes stylists, pens, and even credit card machines because the virus can live on surfaces."There are some studies that say that COVID-19 is possibly able to survive on a surface like plastic for about three days so it's definitely possible," Egger said.But can the virus live on food?"It appears as though coronavirus and COVID is actually heat sensitive, which means that most of the time, those temperatures we're cooking those food items too is able to cook off any kind of the virus," she explained.And you may have heard that eating outside is safer than inside. So why is that?"I believe there were three reported cases of people consuming food in restaurants in an enclosed area and they actually did find the virus in the air conditioning system," she said.And masks are a must right now."Anybody that's facing our customers should be wearing masks, that includes general managers. That includes anybody who's out on the floor, interacting with customers or employees," she said.And the biggest mistake people make when wearing a mask? They don't cover their nose."You're still running the risk of inhaling that potentially contaminated air. So we have to keep everything covered," she explained.Egger also recommends restaurants display on their door what they're doing to keep you safe and what they expect of their customers.That may include things like 'masks required', 'please social distance' or 'think about take-out if you're not feeling well.'''Egger says disposable menus are the safest but if a restaurant hands you a reusable menu, they should be sanitizing that menu between each customer.WFTS' Wendy Ryan first reported this story. 2971
