Health officials agree coronavirus cases are going to increase this winter as Americans head indoors to stay warm and closed windows will lead to less ventilation.But what about the dry air inside and outside this time of year, could a humidifier help slow the spread of coronavirus? That is still being debated.A study released this month seems to suggest increasing humidity plays a role in decreasing cases of coronavirus. The study, which has not been peer-reviewed yet, was shared on medRxiv.This study was based on the premise that previous studies have shown that falling humidity is tied to increased transmission rates of other respiratory diseases, like the flu. Researchers looked at more than 3,000 counties around the country and their humidity levels between March and September 2020.The team says they found increasing humidity levels had a negative impact on new cases of COVID-19 in most regions. In two of the regions that showed the highest effect, a 1 g/m3 increase in absolute humidity resulted in a 0.21 and 0.15 decrease in COVID-19 cases.However, there are also studies that show the humidity level had little to no effect on the spread of COVID-19.A study released in early November found the weather had “virtually no impact” on the spread. Instead, they said human behavior changes during weather fluctuations, outside during warmer weather and heading indoor during cold weather, had a large impact.What health and science experts seem to agree on is that the air does get drier in the winter from both the cold air outside and heated air inside. And that without proper ventilation, any coronavirus droplets in a space could linger longer and become more concentrated.This dry air can also cause nasal passages to dry out, which means noses could have less protective mucus. Some doctors have said whether or not the science completely proves humid air can help slow the spread of coronavirus, having more humidity in the air can make this winter more comfortable and noses more able to protect against all virus. 2051

Holidays will look different this year for many Americans, with dinners outside, social distancing, or passing on family gatherings altogether. But several companies developing rapid at-home COVID-19 tests are hopeful that won't be the case next year. The goal is to make inexpensive, easy-to-use COVID tests that can deliver results in minutes, just like a pregnancy test. "For people to feel comfortable to associate with friends or family, there needs to be a testing methodology ideally that can be performed at home," said Tony Lemmo, CEO of the manufacturing company BioDot.The company's technology is being used by over 70 manufacturers worldwide making COVID-19 antigen, antibody, and PCR tests. Their automated platforms dispense nanoliter/picoliter amounts of reagent onto the tests accurately and fast.Lemmo says just one of their systems can support the production of roughly 100 million COVID-19 tests per year, helping to make high-volume production possible.“We knew we were going to be called on by customers to manufacture more equipment to provide them the ability to manufacture more tests," said Lemmo. To meet customer demand, BioDot increased staffing and built a new facility, compressing production time from months to weeks. The FDA recently authorized the first rapid at-home test that can deliver results in 30 minutes, eliminating the need for a lab to test the sample. But the molecular single-use test will only be available to patients with a doctor's prescription who are suspected of being infected with COVID-19.Companies developing tests hope the FDA will soon authorize another at-home testing tool: the rapid antigen test.These inexpensive tests provide results within minutes, and companies developing them say millions could be sold without a doctor's referral.“From what we’re hearing, it’s really just a matter of possibly months before there’s at least sufficient data to be able to support an at-home use of a test like an antigen test," said Lemmo.Lemmo says if authorized by the FDA, manufacturers could make millions of these tests in a matter of months. But antigen tests are less accurate, and the FDA wants to ensure they'll be simple enough for people to use at home. There are also concerns over how the data will be reported to health authorities. “I think any at-home testing or massive rollout of a test into the communities needs to be done very carefully and with a lot of education around it," said Clinical Lab Director Melissa Miller. Dr. Miller is a professor of pathology and laboratory medicine at the University of North Carolina Chapel Hill and Medical Director for the Clinical Microbiology Lab for the Medical Center.She worries the inaccuracies of these tests could eventually lead the public to lose trust in all testing. “Even at 98 percent specificity, which is very, very high. That means you’re going to have a false positive two out of every 100. If you started testing a hundred million people, this is millions of people who have a false-positive test," said Dr. Miller. She says this could lead to healthy people isolating and missing work or school unnecessarily, and false-negative results could give people a false sense of security. “These rapid antigen tests were pushed out to skilled nursing facilities; this is a very high-risk patient population. This is actually where you want a very accurate test," said Dr. Miller. She says it’s unclear how well antigen tests detect the virus in asymptomatic patients but agrees more data is needed to figure that out.“It might make more sense for K-12 schools, or even college settings, where there’s less risk for a poor outcome if you have a false positive or a false negative," said Dr. Miller. But with a growing demand for convenient at-home testing, manufacturers are hopeful that in the months ahead, the FDA will soon open the door to new solutions. 3889

Hospital nurses in Philadelphia are ready to go on strike amid a surge of coronavirus cases across the country, according to the union. The union said in a statement that 800 members of the union at St. Mary Medical Center are planning to picket on Tuesday and Wednesday. One of the main sticking points is minimum staffing levels, which is the proportion of patients to nurses in a hospital.“Safe staffing is the main issue in our negotiation--it's why we organized last year in the first place,” says Kathy McKamey R.N., who works on St Mary's MG2 unit and has been at the hospital for 10 years, said in a statement provided by the union. “Trinity has refused to commit to the minimal safe staffing guidelines every study out there has said improve patient outcomes. But the truth is, even if they had, we don't have the staff to fill them because our wage scale is so far below that of area hospitals. Nurses are literally fleeing to other hospitals 20 minutes away where they can make to more an hour. My unit alone has lost 20 nurses since January; the perioperative areas have lost 35 nurses in the last year. The grids are meaningless if you can't find nurses to fill the spots."Adding to nurses’ concern is the possibility of having to report to work while infected with the coronavirus. Last week, the state of North Dakota called upon asymptomatic nurses to remain on the job amid a spike in COVID-19 cases and a shortage of nurses.“Nurses working across all health care settings and specialties are essential to combating COVID-19,” wrote Tarik Khan and Betsy M. Snook of the Pennsylvania State Nurses Association in a joint statement released Monday. “Unfortunately, nearly 400 nurses in the United States have died due to COVID-19, and many others have been infected and hospitalized. This lack of protection for our nurses is unacceptable. Nurses and health care workers who are risking their lives, and the health of their own families, deserve better.“They deserve all of the PPE, testing, supplies, and safe staffing they need to fight COVID-19 and, if they contract the virus, all of the rest that is required to mend and fully heal. Health care organizations should use all other staffing resources for replacement providers so that those nurses who test positive for COVID-19 can get the required rest to recuperate.”Hospitals in the Philadelphia area told the Philadelphia Inquirer that they would hire replacement nurses to work if the union goes on strike."We respect the union members’ right to strike, and we remain committed to negotiating in good faith to reach agreement on a fair, consistent and sustainable initial contract for St. Mary nurses. We look forward to the day productive negotiations can resume," said a statement from Trinity Health. Coronavirus cases in Pennsylvania reached record levels last week, topping 5,000 cases in a single day for the first time since the start of the pandemic. In response, the city of Philadelphia announced on Monday plans to close indoor dining, gyms and museums in hopes of reducing the spread of the virus. 3096

Hours after a chaotic presidential debate, Democratic presidential nominee Joe Biden embarked on a train tour through northeast Ohio and western Pennsylvania on Wednesday.Biden made seven stops in towns and cities throughout the region. He delivered an address in Cleveland at about 10 a.m. ET upon his departure and his tour concluded in Greensburg, Pennsylvania, east of Pittsburgh.During several terms as a Delaware senator and throughout his time as Vice President, Biden became known for commuting back and forth between Washington and his home in Wilmington, Delaware via an Amtrak train, earning him the nickname "Amtrak Joe."On Tuesday evening, Biden and President Donald Trump traded political barbs and personal insults in a messy presidential debate. Trump often interrupted both Biden and moderator Chris Wallace, preventing either candidate from fully expressing their campaign positions.Recent national polls show Biden still holds a lead over Trump a month out from the election. However, Biden will need a strong showing in Pennsylvania — a state that went to Trump in the 2016 election. Polls show that Biden has a small lead in the Keystone State and that Ohio is currently a toss-up race. 1215

GRAND RAPIDS, Mich. — The pandemic has been an isolating and difficult time for people who struggle with substance abuse and addiction, said Kristin Geitzen. She’s the CEO of Arbor Circle, an organization that provides a variety of mental health, substance abuse, and family supported services, and she and her team are worried for their patients.“You’re sitting around your house and people are drinking, drinking more than they had before or trying to self-medicate, or a variety of issues and concerns,” Gietzen said during a Zoom interview last week. “Substance abuse is a big deal and we’ve had overdoses during this time.”Geitzen said people have entered treatment for the first time after recognizing that they had a problem during the pandemic. Sobriety has been hard to maintain for some. Now, with more restrictions set to take place as cases spike across the country, the team at Arbor Circle fear that it could get worse for their patients and they're concerned about the impact it may have others, especially children.“We’re seeing in the child welfare system, we’re seeing a decline in reports of child abuse and neglect, and a decline in removals into foster care, which on the one hand is a good thing because we want children to stay in their families but we also know that abuse and neglect is often reported through school,” Gietzen said. “Where people are stressed, sometimes bad things can happen.”Accountability is key, she said. Typically, at Arbor Circle, they’d meet with their patients in person and check in on how things are going. However, with the pandemic going on it’s been hard to do.“People are also afraid to come into social settings or into treatment settings for good reasons. Many folks that have substance abuse disorders also have compromised health. They’re living with some of the risk factors that make COVID that much more risky,” Gietzen said. “So, it’s really a dance to try to figure out how to navigate this time for everyone.”However, the team and therapists at Arbor Circle are determined to help their patients endure, she said. They, like Alcoholics Anonymous and other mental health services, have shifted their work and appointments online. They encourage people who struggle with substance abuse to pay attention to their bodies and to respond to it positively by creating new habits.“With winter coming, you know we can all get very physically complacent,” Geitzen said. “We can do a lot to help our mood and help our circulation and all of the things that positively impact the way that we think by doing some physical activity. It’s critical.”Gietzen said she understands how hard it can be to stay motivated. She practices yoga and said it’s been difficult doing it on her own. However, she encourages others to find ways to stay motivated. She said the pandemic is like a marathon that's going to require endurance for everyone to get through.“We’re all in this situation together, as a community, as a nation, the whole world,” Gietzen said. “We are learning and experiencing something totally new. And, some of the tools and the tricks and treatment methods that we used in the past are not as effective right now. So, we have to all sharpen our tools.”This story originally reported by Lauren Edwards on FOX17online.com 3292
