The U.S. decline in cigarette smoking could be stalling while the adult vaping rate appears to be rising, according to a government report released Thursday.About 14% of U.S adults were cigarette smokers last year, the third year in a row the annual survey found that rate. But health officials said a change in the methodology make it hard to compare that to the same 14% reported for 2017 and 2018.The adult smoking rate last saw a substantial drop in 2017, when it fell from 16% the year before.The new figures from the Centers for Disease Control and Prevention mean there are more than 34 million adult smokers in the U.S.Meanwhile, about 4.5% of adults were counted as current e-cigarette users last year — about 11 million people.That rate appears to be up from 3.2% in 2018 and 2.8% in 2017. But again, officials said that comparing 2019 with earlier years is difficult because of the survey change.The CDC figures are based on responses from about 32,000 people.Health officials have long called tobacco use the nation’s leading cause of preventable disease and death.___The Associated Press Health & Science Department receives support from the Howard Hughes Medical Institute’s Department of Science Education.

The Trump administration is considering a new travel ban to replace its original executive order, which has had its legality questioned and is up for a Supreme Court hearing next month, White House national security adviser H.R. McMaster said Sunday."Well, this is something that we're looking at, is how to protect the American people better, how to ensure that we know who these people are who are moving," McMaster told George Stephanopoulos on ABC's "This Week."This renewed discussion of the travel ban comes after Friday morning's terrorist attack in London, in which 30 passengers on a London Underground train were injured after a bomb went off.In a tweet Friday in response to the attack, President Donald Trump called for a "larger, tougher and more specific" travel ban and also called for shutting down terrorist group's use of the internet for indoctrination and recruitment.McMaster echoed the point Sunday."Because of the strength of these terrorist organizations -- why this is a greater danger than ever -- is, first of all, their ability to communicate, to connect what would otherwise be disconnected cells in other places in the world," he said. "The second part of this is their ability to travel and to move and to move people and money and weapons, oftentimes drugs and other illicit goods, internationally. So part of the strategy must be to interdict these networks, interdict them from how they use information, and communicate, but how they move physically, as well.The Supreme Court is set to hear?oral arguments in the travel ban case early next month.The President's executive order would suspend travel from six Muslim-majority countries (Iran, Libya, Somalia, Sudan, Syria and Yemen) for 90 days while the secretary of homeland security and others submit a report on the results of a worldwide review to identify what additional information will be needed from each country to make sure an individual seeking entrance is not a public-safety threat.Responding to a lawsuits from states challenging the ban, the Supreme Court let much of the ban take effect in late June, meaning the 90-day clock started and will hit on or around September 24.Administration officials have not divulged the specifics of their future plans.At a recent homeland security conference in Washington DC, acting Customs and Border Protection Deputy Commissioner Ronald Vitiello said, "We are in the process of action planning about each of the opportunities that the US government has to interview and/or vet potential inbound travelers."That could include "looking at things like social media, looking at things like smart phones, those kinds of windows, if you will, into people's backgrounds and their activity," he said.The-CNN-Wire 2771

The University of Arizona and Boeing joined forces to find disinfectants that will kill COVID-19 and help make air travel safer. The project known as the Confident Travel Initiative is designed to test out cleaning solutions that can destroy the Coronavirus. Arizona microbiology professor Dr. Charles Gerba, who is known as "Dr. Germ," says he’s been working with Boeing since the summer to test cleaning products as part of the initiative to make flying as safe as possible during the pandemic and beyond.“It's really innovative to try to get a coating that will be antiviral," he said. "I think it’s the next step in hygiene and disinfection adding another barrier between when they clean and regularly disinfect aircraft. We’re looking at coatings. And anytime the virus lands on it would kill it, so you don’t have to keep disinfecting all the time."The team conducted laboratory testing by using a virus called MS2 on surfaces inside of an unoccupied plane. The virus has similar characteristics to the virus that causes COVID-19.“It would protect you from when they disinfect it or clean the aircraft. In case the virus lands again on a surface in the aircraft. We’ve been evaluating the overhead bins, the seats, the trays, the handles,” Gerba said.Cleaning solutions and ultraviolet wands were also used throughout the plane and according to Boeing, the results show that antimicrobial coatings were effective for extended periods of time and won’t be harmful to passengers. While Gerba didn’t share the names of the disinfectants, he did say the products can potentially be used on public transportation and other high traffic areas.“We actually did some of the work in the aircraft going in and contaminating certain areas like the tray in the aircraft the overhead bin and then evaluating the disinfectants to show they could kill the virus," Gerba said. "I see this new technology of self-disinfecting surfaces will revolutionize public places in cleanliness, cars, and buses you name it. These are products already on the market and they are new innovative products where you can put down a coating and it will last for hours, weeks, or maybe even months."The research project is expected to be done with other viruses by the end of the year and airplane cleanings will be done between flights.“It all has a big benefit I think it's going to add that extra barrier to me it’s the next generation of infection control and the spread of disease,” Gerba said.This story was first reported by Shawndrea Thomas at KGUN Tucson, Arizona. 2552

  

The U.S. again broke its daily record for new confirmed cases of COVID-19 on Wednesday, as local health departments recorded 50,000 new confirmed cases of the virus, according to a database kept by Johns Hopkins.The previous record was set Tuesday when health departments reported about 45,400 new cases.The figures highlight a continued spike in cases throughout the country over the past few weeks. Prior to the recent peak, the highest daily increase in confirmed cases came on April 24, when health departments reported about 36,400 new cases. The U.S. has recorded at least 38,900 new cases every day for the last week.(John's Hopkins)Because the Johns Hopkins database is reliant on reporting from local health departments, the data doesn't necessarily reflect a patient's day of infection. Daily case numbers are often higher mid-week because some local health departments or test centers may be closed on weekends.It's not just cases that are on the rise. According to the Institute for Health Metrics and Evaluation at the University of Washington, use of hospital beds, ICU beds and invasive ventilators have all risen in recent weeks after months of falling resource use.Many states have either "paused" or chosen to take steps back in their reopening process as cases and hospitalizations linked to the virus continue to rise.On Tuesday, Dr. Anthony Fauci — the government's top expert on infectious diseases — called the recent spike in cases "disturbing," and said that he could foresee the U.S. reporting up to 100,000 new COVID-19 cases a day if recent trends continue. 1593

  

The Rev. Al Sharpton vowed to press for justice as he delivered the eulogy Thursday for Stephon Clark, an unarmed African-American man shot dead by Sacramento police.The sanctuary at Bayside of South Sacramento Church overflowed with people, so many sat outside as the funeral for the 22-year-old Clark took place."We will never let you forget the name of Stephon Clark until we get justice," Sharpton told mourners.Sharpton spoke into the microphone while being hugged by Clark's brother Stevante, who had just interrupted the service with an emotional plea to never forget his brother.Police fatally shot Stephon Clark in his grandmother's backyard on March 18, leading to days of protests. Police said they thought Clark had a gun, but only his cellphone was found at the scene. 789
