The Centers for Disease Control and Prevention is now publicly acknowledging people can be infected with the coronavirus through airborne transmission, especially in enclosed spaces with inadequate ventilation.The update embraces growing evidence and international research showing the coronavirus can linger in the air longer - for minutes and hours - and travel farther than six feet.The update comes two weeks after the official CDC website was updated to reflect this, only to be removed a few days later with the agency saying it was “posted in error” before it was fully reviewed.The draft language seemed to imply aerosol or airborne transmission was the main way the coronavirus spreads, and the CDC says that is not the case.“Infections occur mainly through exposure to respiratory droplets when a person is in close contact with someone who has COVID-19,” the CDC states.Their added section is titled “COVID-19 can sometimes be spread by airborne transmission,” and includes information about smaller particles lingering in the air after an infected person had left the space. "Some infections can be spread by exposure to virus in small droplets and particles that can linger in the air for minutes to hours," it reads.“There is evidence that under certain conditions, people with COVID-19 seem to have infected others who were more than 6 feet away. These transmissions occurred within enclosed spaces that had inadequate ventilation. Sometimes the infected person was breathing heavily, for example while singing or exercising,” the new section on the CDC’s website reads. “These transmissions occurred within enclosed spaces that had inadequate ventilation.”The World Health Organization changed their guidance in July and noted the prevalence of airborne transmission of coronavirus and particles lingering in the air. Hundreds of scientists encouraged the WHO to make the acknowledgement following research and studies. 1943

The Cameron Peak Fire is now the largest wildfire in Colorado's history. It grew overnight and is now 164,140 acres, but it remains 56% contained and no injuries have been reported.The fire became the largest in Colorado history Wednesday evening. It took only 48 days for the Cameron Peak Fire to surpass the 139,007-acre Pine Gulch Fire as the largest in recorded state history, and also blew past the 137,760-acre Hayman Fire in 2002.In a Thursday morning update, Operations Section Chief Paul Demerico of Rocky Mountain Team 1 said they are expecting a challenging few days ahead."But we have beefed up and feel like we have adequate resources to do what we can, especially when it comes to structure protection," he said.Several areas near the fire are under mandatory or voluntary evacuations as a result of the blaze. Highway 34 was also temporarily shut down in both directions between Loveland and Estes Park to help with evacuations, but has reopened.In addition, the Canyon Lakes Ranger District of the Roosevelt National Forest closed Thursday morning. This closure includes recreation sites — including all campgrounds — trails and Forest Service Roads.View the mandatory evacuations in the map below, or go here for the full list of evacuations and closures.Demerico said the western side of fire is almost all contained, but the fire was able to run east all the way to County Road 27 thanks to the wind, terrain and dry fuels.The main objective for the next day or so is to keep the fire south of 44H Buckhorn Road and west of County Road 27, he said.Winds will continue to be a problem over the next few days, Demerico said. Structure protection resources are scattered around Storm Mountain, Cedar Park, Glen Haven and Estes Park.The gusts also prevent fire officials from flying aircraft to help fight the blaze from the air.Larimer County residents may see periods of moderate to heavy smoke in their neighborhoods Thursday, according to the Colorado Air Quality Summary. The smoke may impact Fort Collins and Loveland as well.The National Weather Service said smoke from both the Cameron Peak Fire and the new East Troublesome Fire in Grand County will move toward Denver Thursday afternoon.The state's 10 largest wildfires in history, ranked by acreage, are:1. Cameron Peak Fire (2020): 164,140 acres2. Pine Gulch Fire (2020): 139,007 acres3. Hayman Fire (2002): 137,760 acres4. Spring Fire (2018): 108,045 acres5. High Park Fire (2012): 87,284 acres6. Missionary Ridge Fire (2002): 72,962 acres7. 416 Fire (2018): 54,000 acres8. Bridger Fire (2008): 45,800 acres9. Last Chance Fire (2012): 45,000 acres10. Bear Springs/Callie Marie fires (2011): 44,662 acresNote: The Rocky Mountain Area Coordination Center said the West Fork Complex fire, which burned a total of 109,632 acres in 2013, is not included on this list since it involved three separate fires.This story was originally published by Stephanie Butzer at KMGH. 2951

The Georgia Democratic Party and gubernatorial candidate Stacey Abrams' campaign filed a lawsuit in federal court Sunday asking for rejected absentee ballots and provisional ballots to be counted in the Georgia governor's race.The lawsuit challenges the rejection of more than 1,000 absentee ballots for missing information or mismatching information, like birth dates or addresses.The lawsuit also seeks relief for voters whose provisional ballots were rejected in Gwinnett and Dekalb counties, which are in the Atlanta metro area, because they are registered in a different county.CNN has not projected a winner in the race.Republican candidate Brian Kemp currently leads Abrams with 50.3% of the vote. If Kemp's share dips below 50%, the race automatically goes into a run-off on December 4, even if Kemp is the top vote-getter. For now, Kemp's lead stands at nearly 59,000 votes. 891

  

The FBI held an unforeseen news conference on Wednesday to say that Iran and Russia have been leading a misinformation campaign ahead of this year’s election.Although the sudden nature of Wednesday’s news conference made the announcement seem urgent, intelligence community officials have been warning of interference by Iran, China and Russia for months.Director of National Intelligence John Ratcliffe said that the countries obtained voter registration information, and then used that data to direct misinformation toward voters. Ratcliffe, along with FBI Director Christopher Wray, would not take any questions.Voter registration information is generally public information. Information like voters’ names, addresses and voting history are generally available nationwide. It is unclear if Iran and Russia received information that is publicly available."We have already seen Iran sending spoofed emails designed to intimidate voters,” Ratcliffe said.Ratcliffe claimed that the emails worked to hurt Trump's campaign, but House Democrat Ted Lieu, a member of the Intelligence Committee, questioned how the emails were intended to hurt Trump's campaign. 1164

  

The Federal Trade Commission (FTC) is cracking down on glasses and contact prescribers who may try to stop you from shopping around.The FTC sent warning letters to almost 30 different eyeglass prescribers. The letters say the prescriber must give a copy of the prescription to the patient without them asking.They can't charge a special fee for doing that and they can’t force you to buy from them just because they did the examination.“However, there were a lot of prescribers that just weren't doing that,” said Linda Sherry, Director of National Priorities at Consumer Action. “If you asked for it, in most cases, you would get it. They also are required to post notices in the offices to say that you have a right to your prescription and a lot of prescribers we're not posting those notices.”Consumer Action is educating people on their eyeglass and contacts prescription rights. Sherry says prescriptions allow you to go online and to other eyeglass and contact sellers to shop for the best deal.Another thing she says to ask for, especially if you're shopping online, is pupil distance. It may not be on the prescription.“I had an experience where I asked for the pupil distance and was told that would be to put the pupil distance on, so I was like, ‘I've been coming here for three years and you've obviously measured my pupil distance, because I bought glasses from you. So, all you have to do is open your records and tell me my pupil distance.’ And they did do it, but there was that moment there when she said for the pupil distance measurement when I thought, ‘oh, something's very, very wrong here.’”Prescribers shouldn't be charging for that info either.If you're having trouble getting prescription information from your provider, you can contact the FTC. But remember you may also be due for a new eye exam. State laws vary but most eye prescriptions are only good for one year. 1912
