Monday morning, the CDC removed what it calls was a “draft version of proposed changes” to their website that seemed to indicate they were embracing mounting evidence that COVID-19 is airborne and is transmitted through tiny droplets that can linger in the air and spread farther than six feet.“A draft version of proposed changes to these recommendations was posted in error to the agency’s official website. CDC is currently updating its recommendations regarding airborne transmission of SARS-CoV-2 (the virus that causes COVID-19). Once this process has been completed, the update language will be posted,” the CDC website now reads.The website was changed over the weekend, according to multiple media reports, to reflect several updates to their guidance about how COVID-19 spreads and preventative measures to take.The “draft” changes included stating COVID-19 transmits through the air and warned about poorly ventilated situations, saying that is “thought to be the main way the virus spreads.”On the Centers for Disease Control and Prevention’s website about coronavirus, under how it spreads, they listed the main way as: “Through respiratory droplets or small particles, such as those in aerosols, produced when an infected person coughs, sneezes, sings, talks, or breathes. These particles can be inhaled into the nose, mouth, airways, and lungs and cause infection.”They also had updated the guidance that particles can remain in the air longer and travel farther than originally thought.“There is growing evidence that droplets and airborne particles can remain suspended in the air and be breathed in by others, and travel distances beyond 6 feet (for example, during choir practice, in restaurants, or in fitness classes). In general, indoor environments without good ventilation increase this risk,” the CDC website read over the weekend.The website has been changed back to their previous guidance which states COVID-19 is believed to be transferred through larger droplets through close contact, closer than six feet, with a person who coughs, sings, or otherwise expels these larger droplets carrying the virus.The updated draft passages and comments on smaller particles and ventilation appeared to embrace recent studies from the CDC.Including one released by the CDC earlier this month showing Americans with positive COVID-19 test results were twice as likely to eat at a restaurant or cafe than those who tested negative.“Reports of exposures in restaurants have been linked to air circulation. Direction, ventilation, and intensity of airflow might affect virus transmission, even if social distancing measures and mask use are implemented according to current guidance. Masks cannot be effectively worn while eating and drinking, whereas shopping and numerous other indoor activities do not preclude mask use,” that report stated.In the “draft” changes to the CDC website, they included a preventative measure about ventilation, stating “Airborne viruses, including COVID-19, are among the most contagious and easily spread.” That passage is no longer on the website.The draft changes on the air transmission of COVID-19 also came on the heels of the CDC’s director, Dr. Robert Redfield, saying masks could be even more helpful in combating the coronavirus than a vaccine. President Donald Trump said later Redfield was confused by the question and misspoke.The World Health Organization changed their guidance and noted the prevalence of air transmission, and those particles lingering in the air, earlier this summer in July. Hundreds of scientists encouraged the WHO to make the acknowledgement following research and studies. 3665

NATIONAL CITY, Calif. (KGTV) -- A car flipped into the front yard of a home in National City late Sunday night, police say. According to police, the crash happened on the 2500 block of Ridgeway Drive around 11:30 p.m. Police say the driver of the vehicle somehow lost control of the vehicle, flipping over and landing in the front of the home. The car then caught fire, but crews were able to quickly extinguish the flames before they spread. According to police, the crash took out a fence, street sign and a mail box. The driver fled the scene after the crash, sparking a hit-and-run investigation. 609

MONTEREY, Calif. (KGTV) - A California State University, Monterey Bay professor will receive a substantial grant from the Defense Department to find methods to harness fog. The 6,589 gift will fund research on ways to use mesh-based devices to collect water circulating in fog, according to CSUMB. The DoD is interested in the study to collect usable water for drinking or irrigation, which may be useful for military personnel in remote foggy regions. "The presence of fog affects visibility and can impact Army operations,” Julia Barzyk, the program manager for Earth Materials and Processes at the Army Research Office told CSUMB. “We are excited that this award will enable the science needed to mitigate those effects as well as provide opportunities to develop the next generation of scientists." College of Science Professor Dan Fernandez, who has a doctorate in electrical engineering, plans to buy two FM-120 Fog Detectors for his research. There are 106 of the devices in the world, Fernandez reported.“We live in a region where coastal fog is an important aspect of our place. It makes sense that this effort is taking place here and that it can also involve our students who then get to experience the fog both personally, while attending CSUMB, and by participating in state-of-the-art research involving fog,” Fernandez told CSUMB. 1356

NASA's Parker Solar Probe has broken the world record for the closest approach to the sun ever achieved by a man-made spacecraft — and it's not stopping yet.The probe surpassed the previous record of 26.55 million miles from the star's surface on Monday October 29 at around 1:04 pm ET.The previous record was held by the Helios 2 craft, which was launched from Florida's Cape Canaveral Air Force station in 1976.The Parker Solar Probe is now expected to continue its approach, passing through the corona, or the sun's outer atmosphere, next week, reaching within 15 million miles of its surface. 604

MIRAMAR, Calif. (KGTV) — Nearly 50 years after 15 men lost their lives at Naval Air Station Miramar, one man recounted his memories hoping to keep their story alive.Monday, Dec. 22, 1969 was Darwin Ludi's first day back from Christmas vacation. He was on rotation at the Balboa Naval Hospital in the morgue as a Navy Corpsman.When he walked in that morning he described the horrifying sight, "there were body bags along the hallway and I was like, 'What is going on?" RELATED: MCAS Miramar dedicates plaque to Marines killed in 1970 training crashHe said the men were unrecognizable. He said the initial shock stayed with him for months and to this day is his strongest memory."We did the autopsies over a couple of days and the smell just lingered," he said somberly.Photos from MCAS Miramar's archives capture the panic and pain. Around 10:30 a.m. one article says the pilot of an F-8 Crusader ejected after reporting low oil pressure and engine seizure. He said he had no control over the plane.After ejecting, the plane veered right, according to the article, straight into a hangar.RELATED: MCAS Miramar crucial training hub, as political tensions rise around the world"They had, from what I understand, probably 60 some people working in the hangar at the time," Ludi said.The article described a 'big ball of flame belch[ed] from the doorway' then more explosions. "With all the like I said ordnances and it was fuel tanks in there, they were blowing up," Ludi said.The article stated at least 12 were injured from the crash, two jets were destroyed, another damaged extensively. The damage initially tallied around million.Fifty years later he hopes telling their story will keep those who made the ultimate sacrifice from being forgotten, "as long as I'm around hopefully things like this come out, because it's important. It's important to the San Diego community."Important especially in the middle of the holiday season. 1944
