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 The study, which has not been peer-reviewed yet, was shared on medRxiv.This study was based on the premise that previous studies have shown that falling humidity is tied to increased transmission rates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

From football stadiums to movie theatres, the idea of large crowds is still terrifying to a lot of people during this pandemic, but a new invention that helps kill COVID-19 germs instantly could help get people back into some of the nation’s most beloved large venues.For Mark Zurevinski, who once traveled the globe managing shows for superstars, business disappeared in an instant this past spring. With both his employees and his own livelihood on the line, Zurevinski looked around at all those stadiums and decided to come up with a solution to help get people safely back into large spaces.“I saw everyone in the entertainment crossing their arms and waiting for the government to find a solution,” he said.In the middle of the pandemic, as businesses worldwide shut down, Zurevinski started a new business called Sani Pass.The company has developed a disinfecting channel walkthrough machine to kill the novel coronavirus. First, the machine takes your temperature, then nozzles spray a fine non-toxic disinfecting solution over your clothes and bags that kill any COVID germs you may have on you.One machine costs around ,000.“We’re not suggesting we’re a cure. We’re suggesting we are a part of a broader arsenal of products that need to be implemented in order to bring us back to some form of normalcy,” Zurevinski added.Zurevinski also knew that if you couldn't move people through the machine quickly, it wouldn't matter.It takes about eight seconds for one person to get a person disinfected in the Sani Pass. The company estimates they could get 55,000 people into a stadium in just 90 minutes.“I wanted to get people back into arena, back into theatres, back into stadiums. Those are large mass gatherings and in order to get people in there quick enough, we had to find a solution that was not 30 seconds, one minute, two minutes each,” he said.Aside from stadiums, Zurevinski is also in talks with some airports who are considering putting the Sani Pass in place. 1992

Heavy rain caused a central Texas river to rise to a near-record level in about a day, leading to a bridge collapse, flooded homes and evacuations.The Llano River rose to nearly 40 feet Tuesday in the city of Llano -- about 35 feet higher than it was just 24 hours earlier before -- thanks to 8 to 10 inches of rain that fell in the area over the past two days, the National Weather Service said.A few miles away, in Kingsland, the swollen river rushed against the top of the RM 2900 bridge for hours, eventually causing it to collapse, video from CNN affiliate KEYE showed. No one appeared to be on the bridge, and no injuries were immediately reported.Video from Darlene Walthall also showed the river washing over the span before the collapse.The Llano County Office of Emergency Management ordered people living within a quarter mile of the river to evacuate Tuesday morning.The Llano River meets the Colorado River in Kingsland. Houses near the Colorado were flooded, resident Terri Kleen said. Video that she posted to Instagram showed water rising to the top of boat dock structures.Law enforcement officers were helping people from flooded areas, she said.In nearby Marble Falls, Dale Heath recorded video of a car stuck in rushing water from a swollen Backbone Creek, a Colorado River tributary.The flooded communities are about a 90-minute drive northwest of Austin.The Llano River's crest of 39.91 feet in Llano was just below the record high of 41.5 feet there in June 1935.The river is expected to recede through Tuesday afternoon, but should stay in the major flood stage -- over 23 feet -- through Wednesday morning. 1654

GENEVA — The head of the World Health Organization says he will self-quarantine after being identified as a contact of a person who tested positive for COVID-19. Tedros Adhanom Ghebreyesus tweeted that he is “well and without symptoms” but will self-quarantine in “coming days, in line with WHO protocols, and work from home.” The U.N. health agency director-general chief has been at the forefront of the global response to the coronavirus pandemic. It has infected at least 46.5 million people and led to more than 1.2 million deaths, according to a count by Johns Hopkins University. 594

Gov. Gretchen Whitmer went to Delaware to meet with Joe Biden as he neared the announcement of his vice presidential choice, two high-ranking Michigan Democrats tell The Associated Press. The officials, who spoke on the condition of anonymity, say Whitmer visited Biden last Sunday. It's his first confirmed in-person meeting with a potential pick. Whitmer, the first-term governor of a battleground state, has long been on his short list of possible running mates. Flight records show a chartered flight left Lansing’s Capital Region International Airport for Delaware Coastal Airport at 5:33 p.m. and returned at 11:16 p.m. 633
