Police dogs in Chile are being trained to detect Covid-19 in humans by sniffing their sweat. 

Chile’s National Police and the Catholic University of Chile are working on a joint project to train three golden retrievers and a labrador to detect “a new odor" in humans which in this case belong to Covid-19 patients, the university’s professor and veterinary epidemiologist, Fernando Mardones told CNN's Spanish-language news network, CNN en Español.

"The selected dogs have years working on the detection of drugs, explosives and other types of things. For them, it is simply learning to detect a new smell, a new aroma," Mardones said.

Coronavirus does not have a smell per se, but sweat does and dogs can be trained to detect the smell of a person going through an infection process, Mardones explained.

"A body that contracts Covid-19 generates volatile organic compounds. A sample is taken from a person in the early stages of the infection. A gauze is left for about 15 minutes on an individual's underarm. That's the sample we store and use to train the dogs with," Mardones explained.   

The “bio-detector” dogs, as they are called by the Chilean police, are expected to be trained by mid-September and sent to places with high concentrations of people – such as malls, sports centers, bus terminals and airports, according to the Chilean police. 

A dog can smell 250 people in an hour, so they can be deployed when these places reopen," Julio Santelices from the Chilean police said.

"Their olfactory capacity is so great that they would be able to detect the disease early on" Santelices said, adding that "this means that an asymptomatic person could be detected by the bio-detector dog." 

The dogs can take from two weeks up to two months to be fully trained. The canines are being taught to sit next to the individual with the Covid-19 virus they have detected, instead of "pawing" the individual as they currently do when sniffing drugs, the Chilean police told CNN.

FDA experiencing "basically double our normal workload" during pandemic, US official says

US Food and Drug Administration Commissioner Dr. Stephen Hahn said he was surprised how quickly the pandemic spread and is pleased with how quickly scientists have been able to react to get Covid-19 therapies out in record time.

Hahn became commissioner of the FDA in mid-December and had thought the opioid epidemic and youth e-cigarette use were going to be some of the biggest issues he’d tackle first. But within weeks, Covid-19 had started to spread and the FDA had to step up the pace to keep up with new drug and therapy approvals.

“It's basically double our normal workload, and then think about that same number of people, same deadlines that we have to meet for our regular work, but it doubling of that workload because of Covid-19. So literally, our staff were working night and day to get through this backlog of applications,” Hahn said Wednesday at a Paley Center for Media webinar

Only months into the pandemic, the FDA is overseeing 140 clinical trials and there are more than 450 applications in the pipeline. 

Hahn said the pace is not sustainable, but he’s committed to removing barriers to new drug approvals and to speeding up the process. He thinks there are lessons to be learned from what they have done.

One way the FDA has been able to speed up the process by prioritizing the applications that were submitted based on the merit of the science involved. The FDA used groups of agency scientists, doctors, nurses, pharmacists and others to go through applications and determine what the priorities should be.

The agency also expedited the approval process by doing what the agency calls a rolling review, where it looks at data in real time. When the clinical trials and application for a new therapeutic or drug for Covid-19 patients is complete, the FDA can make a decision about the safety and efficacy of that product within days, and in some cases, within 24 hours of getting the final data set. 

“It would be difficult to sustain a, double the workload moving forward, but a model that we’re very interested in implementing as we move forward,” Hahn said. “There are some real lessons there for all of us.”

California adds more than 12,000 cases in one day

From CNN's Cheri Mossburg

California added 12,807 coronavirus cases over the past day, Gov. Gavin Newsom announced at a news conference today.

This comes after the state conducted more than 127,000 tests in one day. The positivity rate remains steady at 7.4% over the past two weeks, but the one week rate is climbing and currently holds at 7.6%.

“Every decimal point causes some concern,” Newsom said.

Note: These numbers were released by California Gov. Gavin Newsom in association with the CA Department of Public Health, and may not line up exactly in real time with CNN’s database drawn from Johns Hopkins University and the Covid Tracking Project.

Oregon Gov. Kate Brown said she will be rolling back a number of the state’s reopening measures in response to a growing number of coronavirus cases.

Speaking at an afternoon news conference, Brown said she is expanding Oregon’s mask mandate to now cover anyone ages 5 and older. She said the state recommends children as young as 2 wear masks. Additionally, she said all exceptions to the mask mandate will be removed.

Brown said the state will now mandate all restaurants and bars close by 10 p.m. local time nightly.

She will also lower indoor gathering sizes in public venues to 100, down from 250. The number of people allowed to gather outdoors will remain unchanged at 250.

The new rules are set to take effect on Friday.

Ohio Gov. Mike DeWine today issued a travel advisory for all individuals who come into Oho from states with a Covid-19 positivity rate of 15% or higher. The state is recommending that those individuals self-quarantine at a hotel or at home for 14 days.

“So we would ask people to be careful,” DeWine said. “This is going to be based on a seven day rolling average. We will update the list of states weekly.”

As of today, according to the governor, the list of states that fall under Ohio’s travel advisory include:

  • Alabama
  • Arizona
  • Florida
  • Georgia
  • Idaho
  • Mississippi
  • Nevada
  • South Carolina
  • Texas

Anyone traveling to the state from Puerto Rico is also recommended to quarantine, according to the governor.

Remember: The positivity rate is the percentage of people who test positive for the virus of those overall who have been tested. So, as more and more people are being tested, the focus is shifting to the positivity rate — how many of those tested are actually infected.

GOP Sen. Mitt Romney criticized the Trump administration’s handling of the coronavirus pandemic saying, “I don't think it's been a great example for the world to see America.”

“I mean look at other nations, look at Germany, the EU,” Romney said. “They had some tough times as we did but they came out of them and we're still struggling in part because of lack of effective oversight of this process.”

“I just feel it's taken us a long, long, long time to get to a point where we have rapid testing, which we don't have yet,” the Utah lawmaker said. “Ample testing, which we don't have. Personal protective equipment, it's still in short supply in certain places.”

On the Trump administration, Romney said, “I hope that there is a change in philosophy about wearing masks and recognizing the importance of scientific perspective as we move forward.”

Kansas Board of Education strikes down governor's order to delay start of schools

From CNN's Melissa Alonso and Brad Parks

The Kansas State Board of Education has rejected the governor's executive order to delay the start of schools across the state, according to a statement from Gov. Laura Kelly.  

The state board voted 5-5 on the executive order Wednesday, which means the executive order wasn't affirmed, the Kansas Department of Education said in a tweet.  

Kelly's order would have delayed the start date for all schools in the state from Aug. 10 to Sept. 9 to ensure schools were prepared to mitigate Covid-19 spread, according to the order.   

“The cases of COVID-19 in Kansas are at an all-time high and continue to rise. Our decisions must be informed by public health experts not politics. This vote puts our students, faculty, their families and our economy at risk," Gov. Kelly said in the statement. 

“I will continue to work with our school districts to ensure the safety and wellbeing [sic] of our children and ask every school district to delay the start of school," said Kelly.

Ohio governor extends mask order to include all counties in the state

From CNN’s Rebekah Riess

Starting tomorrow at 6 p.m. local time, all Ohio residents will be required to wear masks while in public, Gov. Mike DeWine announced Wednesday.

“It’s essential that we wear masks statewide in Ohio to contain the spread of this virus,” DeWine said during a news conference.

“We’ve got to get this virus under control, wearing masks is going to make a difference. It will make a difference in what out fall looks like, what we do between now and the next several weeks will determine what our fall is like. We all want kids to go back to school, we want to see sports, we want to see a lot of different things. We want to have more opportunities in the fall and to do that, it’s just very important that all Ohioans wear a mask,” the governor added.

Previously, Ohio had only mandated that counties at a “red” and “purple” risk level wear masks. 

Ohio is part of a growing number of US states that have mandated the use of masks and face coverings while in public.

As more people wear masks, key coronavirus model lowers number of US deaths projected by November

From CNN Health’s Jen Christensen

The University of Washington now projects there will be 219,864 US deaths from Covid-19 by November 1, based on the current scenario.   

Last week, the university’s Institute for Health Metrics and Evaluation forecast 224,546 total deaths by November. 

The latest update reflects a decrease of about 5,000 deaths in part due to increasing mandates for members of the public to wear masks, and the general increase in the number of people wearing masks and social distancing even without mandates. 

If the US universally adopted wearing masks, that number of deaths by November 1 would drop to 185,887, the model projects. However, if the mandates ease more, then the United States could see 231,012 deaths by that time.

Ali Mokdad, a professor of health metrics sciences at IHME, said that they’ve seen more people wearing masks in states that have seen a recent spike in cases such as in Florida, California, Texas and Arizona, but the states that have mask mandates have seen more universal adoption.

“So a mandate is very important and helping and a national mandate, of course, would do much better,” Mokdad told CNN. 

So far, according to Johns Hopkins University, more than 3.91 million Americans have been infected with coronavirus and at least 142,350 have died.
