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 continuing debate about children and vaccines can get pretty heated. One of the concerns is that vaccines weaken a baby's immune system against other diseases, but new findings should ease that fear           For many little ones, routine vaccinations are a rite of passage.  And sometimes, there can be a lot of them."Some parents are concerned that kids get too many vaccines in too short of a time," says Dr. Jason Glanz with the Kaiser Permanente Colorado Institute for Health Research. "So by the age of two children receive up to 10 vaccines and 26 shots and so that is a lot of shots."That's why Dr. Glanz and his team set out to see if getting that many vaccines was harmful."Thankfully our study show that it wasn't harmful," Dr. Glanz says.Dr. Glanz says many parents are concerned vaccines could overload their child's immune system and increase their risk of getting an infection in the future.The NOW's Kumasi Aaron asked Dr. Glanz, "Is there such thing as overloading an infant with vaccines?" "We did not see a list of that," Dr. Glanz replied. "We saw no evidence that receiving all the vaccines and receiving them on time in anyway damaged the child's immune system."The study looked at infants two years after they got those vaccines, and found they weren't likely to be more susceptible to other infections not targeted by those vaccines.Dr. Glanz says, "I'm hoping he provides some reassurance that these vaccines are safe and the benefits greatly outweigh the risks and that if they have any concerns that they should talk about it with the doctors." 1658

The first round of the NFL Draft got underway Thursday evening and Oklahoma quarterback Baker Mayfield was selected as the first overall draft pick by the Cleveland Browns. Mayfield will likely take over as Cleveland's starting quarterback in the fall after the Browns finished the 2017 season with a winless 0-16 record. Mayfield was a three-year starter at Oklahoma after starting one season for Texas Tech. He threw for 131 touchdowns over his four collegiate years, which is fourth all time in NCAA Division I history. According to most NFL Draft experts, five college quarterbacks will likely be selected in the first round on Thursday. The group includes USC's Sam Darnold, Oklahoma's Baker Mayfield, Wyoming's Josh Allen, UCLA's Josh Rosen and Louisville's Lamar Jackson.  807
