What you flush down your toilet could be brought back up to detect COVID-19.“Anytime that we are talking about poop, it’s a subject that either brings laughter or disgust; maybe a combination of the two,” said John Putnam with Colorado Public Health and Environment. Putnam is helping lead a team to test human waste to determine molecule levels linked with the coronavirus.“This gives you early warning that there could be an upsurge or a lessening of the disease in the community,” he said.Putnam says a person that’s been exposed to COVID-19 will pass the virus through their feces and possibly even urine. The waste eventually flows into sewer systems, which scientists will now collect.“We can then take a sample at a wastewater plant and send it to a lab,” he said.Labs at places like Metropolitan State University of Denver.“One of the advantages of this approach is that everybody in the community makes a contribution to the sewage,” said Rebecca Ferrell, Ph.D., a biology professor at MSU Denver.She says that when people get infected with COVID-19, they often shed the virus for several days before showing symptoms. Adding that this specialized stool sampling can alert scientists that the virus is in a community before people start getting sick.“It can give you extra warning about what might be happening in the hospitals then days maybe even a week later when people get sick enough that they are going to make demands on health care that you need to anticipate,” Ferrell said.With the cost to collect this data much cheaper than other options, Ferrell says more scientists are now teaming up with more wastewater treatment plants across the country.“These are the kinds of techniques where a relatively small investment early on can help us to get those resources to the right place and we can keep the mortality low,” she said.Hoping to get ahead of the pandemic, testing number two is becoming the number one priority for some scientists. 1965

While scientists work to come up with a safe and effective COVID-19 vaccine, doctors across the country are watching closely. Many are helping guide their patients in making an informed decision about getting a vaccine."This was indeed a surprise to see that there would vaccines available by the 1st of November. It’s clearly an aspirational goal, because we all would like to see a safe and effective COVID-19 vaccine as soon as possible, but I think testing vaccines to make sure they’re safe and effective is of paramount importance," said Dr. Bali Pulendran, a microbiology and immunology professor at Stanford University.Dr. Pulendran says the process of developing a vaccine involves numerous steps, and scientists are getting closer to the end. Still, it's hard to put an end date on the third and final phase of a vaccine trial. This last phase determines whether the vaccine actually works."The way in which you can assess whether a vaccine works is to see how many of these people acquire the disease or become infected with COVID at some period of time," explained Dr. Pulendran.Phase three divides the trial participants into two groups. One group is given the vaccine, and the other is given a placebo."And then, you calculate the efficacy based on those numbers. So, if there were 200 people affected in the placebo group but there were only 100 people who were infected in the vaccinated group, then the efficacy is 50 percent" said Dr. Pulendran.The third phase is hard to time, as it depends on how quickly some of the trial participants become infected. If they live in areas where COVID-19 infection rates are higher, the phase will be completed faster.But there are some other ways to speed up the vaccine trial.Dr. Darria Long, an emergency room physician and clinical assistant professor at the University of Tennessee-Erlanger, says one way is by doing two of the phases at the same time. Another way is if officials prepare for the manufacturing and logistics side of producing the vaccine during the third phase of the trial."This is what we see the CDC saying is to get ready on the manufacturing and logistics side because even if you come up with the perfect target drug, making sure you can manufacture hundreds of millions and that you have the little glass vials that can keep it at the right temperature, those are all things that can be hang-ups,” said Dr. Long. “So, they're wanting to expedite that process, because the last thing you want is to say is we have the vaccine, but we can’t get it to people.”Dr. Long is already answering her patients' questions as news of a possible COVID-19 vaccine continues to be publicized."I do think a lot of people are wondering about this vaccine and it runs the gamut. There are those that say they really want the vaccine because they see it as this gateway to getting back to life as we know it," said Dr. Long.There are also those who are really concerned about the efficacy and safety of a COVID-19 vaccine. Doctors say a key piece in evaluating a vaccine when it does come out is the data surrounding it."The data that comes out in the public domain: is a particular vaccine efficacious? How effective is it what is the efficacy data? Is a particular vaccine safe? What are the side reactions? And they should talk with their physicians to ask each question. Ask doctors, ‘Could you tell me what the safety part of this vaccine is?" recommended Dr. Pulendran.And above all, doctors and scientists hope politics will stay out of the development of a COVID-19 vaccine in order to ease any concerns or hopes for a vaccine to be available as soon as possible. 3644

White House press secretary Sarah Sanders on Tuesday defended President Donald Trump's silence on allegations leveled against him by porn star Stormy Daniels, maintaining that while the President is a "counter-puncher," he doesn't necessarily punch back at every story.Daniels, whose legal name is Stephanie Clifford, has saturated the news in recent days, after Anderson Cooper interviewed her over her alleged affair with Trump on CBS' "60 Minutes." Trump so far declined to respond to her on Twitter or otherwise, a rarity for a President who rarely holds back.Sanders said even though she has previously described Trump as a "counter-puncher," she didn't say he "punches back on every single topic.""If he did he would probably be addressing a lot of the stories that most of you write every single minute of every single day," Sanders told reporters. "He also has a country to run. And he is doing a great job with that. ... Sometimes he chooses to specifically engage and punch back and sometimes he doesn't."Trump's terse Twitter persona has targeted everyone from Rosie O'Donnell and the cast of Hamilton to his political enemies and one-time friends. But the President has been advised that lashing out on the Daniels story will only make it worse, a tact he is also taking with Karen McDougal, a former Playboy model who recently recounted in a CNN interview the details of what she alleges was a lengthy affair with the then-businessman.Trump has denied both women's claims.Daniels, in her interview with 60 Minutes, alleged that shortly after she tried to sell her story about her alleged affair with the now-President, a man approached her in the parking lot of a fitness center."And a guy walked up on me and said to me, 'Leave Trump alone. Forget the story,' " Daniels said. "And then he leaned around and looked at my daughter and said, 'That's a beautiful little girl. It'd be a shame if something happened to her mom.' And then he was gone."Daniels, as part of a hush agreement, was paid 0,000 by Trump's longtime personal lawyer Michael Cohen days before the 2016 election. Daniels said she was risking a million fine for potentially violating her nondisclosure agreement "because it was very important to me to be able to defend myself."Sanders once again denied the allegations leveled by Daniels, but declined to get into the details of the porn star's allegations or the payoff she received."That is a question you would have to ask the President's attorney," Sanders said. "I certainly cannot speak for him. I can only speak on behalf of the White House."Pushed on the matter, Sanders stood her ground and declined to comment."The President has denied the allegations," Sanders said. "Anything beyond that I would refer you to the outside counsel and his attorney." 2823

When you enter the building at Daybreak Senior Services, pictures of blushing brides and anxious grooms greet you.“This is such a historic place,” said Scott Rasmussen, as he looked at the dozens of pictures lining the walls.Although the fashion trends may have faded, the memories have not.For 50 years, the building was a reception hall. It was a place of celebration, a symbol of new life beginning. Now, it’s a home base for those not ready to give up on life.“It’s a gap that needs to be filled and that’s why we’re here,” said Rasmussen, who is the program director at Daybreak Senior Services.Some days, that means joining a rousing game of indoor badminton or laying down the law playing some board games.Instead of wedding gowns, everyone now wears masks. Though you can’t see the smiles, you know they’re under there."One of our participants loves coming here and she calls it, ‘the club,’” Rasmussen said. “She tells everyone that she wants to go to the club, and I think it’s because we’re doing cool stuff.”Sure, they are doing cool stuff, but the biggest goal for Rasmussen is to help seniors from feeling isolated and alone."It is a real thing,” Rasmussen said. "I’ve known seniors that get so depressed that they say they’d rather just be done than have to go through another week of this because it’s just too hard.”Rasmussen said there is a real need in our country to help seniors who aren’t quite ready for full-time assisted living but are not getting all they need at home."If you’re loved one is just staying home all the time, they’re missing out on a part of their life, where they'd still be growing even as an advanced age 65 to 105,” Rasmussen said. “We can always still be growing.”The adult day care partners with programs through the VA and Medicaid and participants can drop in whenever they want. Programs like this are available all over the country."We love all of our participants. We absolutely love them, and we love what we do here because it’s such a valuable thing,” Rasmussen said.COVID-19 may be affecting their numbers some, but Rasmussen says it’s even more reason for people to reach out to their loved ones and check-in.“You need to just ask those questions, because if you don’t ask you just have a feeling of despair and it just gets harder and harder and that makes it difficult on everyone,” Rasmussen said.There may not be a lot of dancing going on or tossing of bouquets but there is hope and commitment to keep on going. 2482

While officials in Puerto Rico placed the official death toll from last year's Hurricane Maria at 64, researchers from Harvard believe the death toll was actually in the thousands. According to Harvard's study, there were an estimated 4,645 deaths directly or indirectly tied to the hurricane, which struck the island in September. Harvard estimated a mortality rate of 14.3 deaths per 1.000 people from September 20 through December 31, 2017 in Puerto Rico. Harvard said in its study that it believes its estimate is rather conservative due to a "survivor bias."Harvard conducted the study by performing a random survey of 3,299 households in Puerto Rico. "In our survey, interruption of medical care was the primary cause of sustained high mortality rates in the months after the hurricane, a finding consistent with the widely reported disruption of health systems," the study says. "Growing numbers of persons have chronic diseases and use sophisticated pharmaceutical and mechanical support that is dependent on electricity. Chronically ill patients are particularly vulnerable to disruptions in basic utilities, which highlights the need for these patients, their communities, and their providers to have contingency plans during and after disasters."Part of why there the death toll might have been underreported is due to how hurricane-related deaths are counted. In order to have a death counted as storm related, bodies had looked at by a medical examiner, which required a body to be transported to San Juan, or the medical examiner to travel to remote locations. With a lack of electricity and blocked roads, some bodies were likely buried before the government could count fatalities. Maria is considered the third-costliest hurricane in US history.  1816
