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 Department of Justice announced Thursday that 57 people have been arrested across the country for fraud related to the Paycheck Protection Program (PPP).In a press conference Thursday, officials with the Department of Justice said that the suspects attempted to steal millions of dollars of taxpayer money.The PPP was established in the CARES Act, a stimulus package signed into law in March amid the coronavirus pandemic. The funds were meant to be used by small businesses to keep their businesses afloat.Officials said some of those arrested used the funds to buy "flashy or expensive" luxury items for themselves, rather than use the funds for their businesses. The DOJ also described that some of the suspects were part of "coordinated criminal rings" meant to obtain the funds through fraud.While officials did not put a specific dollar amount on the amount of funds stolen, officials called the number "significant." The DOJ says that it was able to seize or freeze million in funds provided through the PPP.This story is breaking and will be updated. 1074

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 FDA issued an emergency use authorization for a saliva-based coronavirus test that has been used to identify COVID-19 cases by NBA players. Leading officials are calling the test a “game-changer.”The SalivaDirect test is said to be both rapid in its findings, and inexpensive. Yale said it doesn’t hope to commercialize the test, rather increase the country’s testing capabilities.“Widespread testing is critical for our control efforts. We simplified the test so that it only costs a couple of dollars for reagents, and we expect that labs will only charge about per sample. If cheap alternatives like SalivaDirect can be implemented across the country, we may finally get a handle on this pandemic, even before a vaccine,” said Nathan Grubaugh, a scientist with Yale Public Health.Yale scientists say that the nasal samples are less invasive than swabbing, but are equally as accurate.“This is a huge step forward to make testing more accessible,” said Chantal Vogels, a Yale postdoctoral fellow. “This started off as an idea in our lab soon after we found saliva to be a promising sample type of the detection of SARS-CoV-2, and now it has the potential to be used on a large scale to help protect public health. We are delighted to make this contribution to the fight against coronavirus.”The test earned praise from members of the White House coronavirus task force.“The SalivaDirect test for rapid detection of SARS-CoV-2 is yet another testing innovation game-changer that will reduce the demand for scarce testing resources,” said Assistant Secretary for Health and COVID-19 Testing Coordinator Admiral Brett P. Giroir, M.D. “Our current national expansion of COVID-19 testing is only possible because of FDA’s technical expertise and reduction of regulatory barriers, coupled with the private sector’s ability to innovate and their high motivation to answer complex challenges posed by this pandemic.” 1926

The Centers for Disease Control and Prevention ensemble forecast projects will be 207,000 to 218,000 COVID-19 deaths in the United States by Oct. 10.As of Thursday, 197,364 Americans have already perished from the coronavirus, according to Johns Hopkins University.With the new forecast, that means approximately 9,600 to 20,600 more people could die in the next three weeks.Two previous ensemble forecasts have already been published: one Sept. 3 and another on Sept. 10.The Sept. 3 forecast projected up to 211,000 deaths by Sept. 26. The Sept. 11 one projected up to 217,000 deaths by Oct. 3. 603
