New spikes in COVID-19 cases have reinforced the importance of basic disinfecting and cleaning our homes to stop the novel coronavirus spread.But how do we know that the cleaners we have are effective in killing COVID-19 and other viruses?"One of the things that's important to know: Is there is a lot of good evidence that the coronavirus is one of the easiest types to kill?" said Texas A&M University - Corpus Christi Associate Professor of Chemistry Dr. Patrick Larkin.Yes, he said. He believes most household cleaners will destroy the virus.He said the best chemicals to use for disinfecting are, bleach, ammonia, and alcohol. However, he does warn that precautions be taken with alcohol concentrations."For example with isopropyl alcohol, you need at least a 50 percent solution; and ethanol [or ethyl] alcohol, you want at least 60 percent," he said.But, take note -- there also are guidelines for how you should clean, so it can be the most effective."CDC guidelines say you should clean the surface with soap and water first, and then apply your sanitizing or disinfectant solution," said retired Certified Industrial Hygienist Tom Samson. "Leave it on for at least one minute, and then you can rinse it off."Samson said not all household cleaners are the same, and do not have the same contact-surface time that is required. He recommends reading the labels of the cleaner you intend to use.Larkin and Samson said it is easy to make your own cleaners at home. However, be cautious about mixing chemicals, and be aware what you are cleaning with."The chemistry of mixing a chlorine-based cleaner with an ammonia-based cleaner can be deadly to those in the immediate area," said Samson. "The reaction of these two cleaners is to release chlorine products into the surrounding environment, in some cases, enough to cause severe injury or death. People need to know to get out of the area if this reaction happens and take their kids and pets with them!"Samson notes the Environmental Protection Agency also has a list of cleaners that will kill the novel coronavirus.This story originally reported by Chelsea Torres on kristv.com. 2149

NEW YORK (AP) — The streaming of “Hamilton” by the Disney+ streaming service was surely the big event on television screens in American living rooms this past weekend. How many people actually saw it remains a mystery. Disney knows, but isn't telling. The Nielsen company is getting that information, too, but deferring to Disney on when it becomes public. The “Hamilton” airing is the most prominent example yet of how consumption of entertainment is changing, but systems for measuring how many people are watching haven't kept up. It's different for television, where it's easy to find how many people watched President Trump at Mount Rushmore, for instance.Hamilton gave Disney+ a huge boost as its most prominent release since debuting. The taping of the hit Broadway show was originally slated for a 2021 theatrical release, but was moved up during the coronavirus pandemic, which has shuttered all Broadway performances since March. 947

NEW YORK — President Donald Trump has canceled an Aug. 15 appearance at a New York Yankees game where he was slated to throw a ceremonial first pitch.Trump said he planned to reschedule the event for later in the season."Because of my strong focus on the China Virus, including scheduled meetings on Vaccines, our economy and much else, I won't be able to be in New York to throw out the opening pitch for the @Yankees on August 15th," he tweeted.Infectious disease expert Dr. Anthony Fauci threw out the ceremonial first pitch in the first game of the season between the world champion-Nationals and the Yankees in Washington on Thursday.Trump celebrated baseball's Opening Day last Thursday with former Yankee closer and Hall of Famer Mariano Rivera, who made an appearance at a White House press briefing.The return of sports is "a tremendous thing psychologically for our country," Rivera said.Later on Thursday, Trump and Rivera joined Little League players on the White House lawn for a catch. 1007

North Korea has agreed to refrain from conducting nuclear and missile tests while engaging in dialogue with South Korea, Seoul's national security chief Chung Eui-yong said Tuesday after returning from a meeting with North Korean leader Kim Jong Un.Chung added that Pyongyang also expressed willingness to talk to the United States "in an open-ended dialogue to discuss the issue of denuclearization and to normalize relations with North Korea."Chung said that as part of the dialogue, the two Koreas would hold a summit next month, the first of its kind in more than a decade.The last inter-Korean summit was in 2007, when South Korean President Roh Moo-hyun met Kim's father, late North Korean leader Kim Jong Il.The meeting will be held at the Panmunjom Peace House on the South Korean side of the demilitarized zone that divides the two countries, Chung said.Pyongyang and Seoul will also open a communication hotline that will enable Kim and South Korean President Moon Jae-in to speak directly.Moon sent Chung and four other top government officials to Pyongyang Monday, when they met with Kim and some of his top aides.It's believed to be the first time the young North Korean leader has ever met with any officials from South Korea since taking power in 2011.Developing story - more to come  1312

Northwestern Memorial Hospital near Chicago says it has successfully completed two life-saving double lung transplants on COVID-19 patients — the first known procedures on virus patients in the U.S.The procedures were conducted on a 28-year-old woman and a 62-year-old man earlier this summer.According to a press release from Northwestern Medicine, Mayra Ramirez arrived at the Northwestern Memorial Hospital with COVID-19 symptoms on April 26. Within 10 minutes of arriving at the hospital, Ramirez was placed on a ventilator."From there, everything was a blur," Ramirez said.COVID-19 had "overrun" the paralegal's lungs, according to Dr. Beth Malsin at Northwestern Memorial."For many days, she was the sickest person in our COVID ICU and possibly the entire hospital," she said.Ramirez spent weeks in the COVID-19 ICU at the hospital, a time that she says she doesn't really remember."All I remember was being put to sleep as I was being intubated and then six weeks of complete nightmares," she told CNN. "Some of the nightmares consisted a lot of drowning, and I attribute that to not being able to breathe."By early June, doctors had decided that the virus had done irreversible damage to Ramirez's lungs, and only a transplant would save her life. After an urgent evaluation, she was placed on the transplant list.On June 5, Ramirez went through the life-saving procedure, just 48 hours after being listed on the transplant list.According to The New York Times, doctors are often extremely hesitant to perform lung transplants — patients must be sick enough to require new organs, but also healthy enough to be able to survive the procedure and rehab. As an otherwise healthy 28-year-old woman, Ramirez fit the qualifications.Ramirez was discharged from the hospital on July 8 — 71 days after she arrived at the hospital. She was the first COVID-19 patient in the United States to receive a double lung transplant.“People need to understand that COVID-19 is real. What happened to me can happen to you. So please, wear a mask and wash your hands. If not for you, then do it for others,” Ramirez said.Exactly one month after completing the first procedure, doctors at Northwestern Memorial performed a second double lung transplant on a COVID-19 patient. 62-year-old Brian Kuhns originally arrived at the hospital on March 18 after suffering from a severe cough.Prior to arriving at the hospital, Kuhns thought COVID-19 was "a hoax," according to his wife, Nancy."I assure you; Brian’s tune has now changed. COVID-19 is not a hoax. It almost killed my husband,” Nancy Kuhns said.Kuhns underwent surgery on July 5. According to the hospital, a typical double-lung transplant takes six or seven hours. Kuhns' surgery took 10 hours because COVID-19 resulted in lung necrosis and severe inflammation in the chest cavities.Kuhns was taken off a ventilator a day after the surgery, and the hospital says he continues to recover at an "optimal" pace."If my story can teach you one thing, it’s that COVID-19 isn’t a joke. Please take this seriously," Kuhns said. 3069
