Chilean police train dogs to sniff out COVID-19

Published

on

Police in Chile are training dogs to detect people that may be infected with the novel coronavirus by sniffing their sweat.

The dogs — three golden retrievers and a labrador — are between the ages of four and five. Until now they have been used to sniff out illicit drugs, explosives and lost people, police say.

The training program is a joint effort by Chile’s national police, the Carabineros, and specialists at the Universidad Catolica de Chile.

It follows in the footsteps of similar efforts taking place in France, said Julio Santelices, head of the police school of specialties.

Dogs have 330 million olfactory receptors, and an ability to detect smells 50 times better than humans. They can also smell 250 people per hour.

“The virus has no smell, but rather the infection generates metabolic changes” which in turn leads to the release of a particular type of sweat “which is what the dog would detect,” Fernando Mardones, a Universidad Catolica professor of veterinary epidemiology, told AFP.

According to Santelices, tests in Europe and Dubai shown a 95 percent efficiency rate in canine detection of COVID-19 cases.

Medical Detection Dogs, a British charity set up in 2008 to harness dogs’ sharp sense of smell to detect human diseases, also started training canines to detect COVID-19 in late March.

“The importance of this scientific study is that it will allow dogs to become biodetectors, and detect this type of illness at an early stage,” Santelices told AFP.

Mardones said that there is already evidence that dogs can detect diseases such as tuberculosis, parasite infections, and even early stages of cancer.

Canines can detect subtle changes in skin temperature, potentially making them useful in determining if a person has a fever.

According to the World Organisation for Animal Health, the possibility of contagion from a dog is remote.

The canine trainees began their education one month ago, and will use sweat samples taken from COVID-19 patients being treated at the Universidad Catolica’s clinic.

The experts hope to have the dogs trained and working in the field by August.

The plan is to deploy them with an officer in pedestrian-heavy areas such as train stations and airports, and at health control stations.

Chile on Tuesday reported 1,836 new cases of COVID-19 — the lowest figure in two months — bringing the total of cases since March 3 to 319,493.

The viral infection has killed more than 11,000 people, according to the most recent Health Ministry official report, which includes “probable” COVID-19 victims.

‘Have you ever heard someone whine as much as this man?’ CNN’s Anderson Cooper tears into Trump’s COVID excuses

Published

on

On CNN Tuesday, anchor Anderson Cooper slammed President Donald Trump after his Axios interview in which he said of coronavirus deaths, "It is what it is."

"For a man who seems to have strength and power, have you heard someone as allegedly powerful and strong as he claims to be — have you ever heard somebody whine as much as this man?" said Cooper. "'It is what it is.' Let me play the last portion of that first exchange again, because he says something telling."

"It is what it is," said Trump in the clip. "But that doesn't mean we are not doing everything that we can. It's under control, as much as you can control it."

Here’s how Mitch McConnell’s Republicans are destroying America

Published

on

Senate Republicans’ shameful priorities are on full display as the nation continues to grapple with an unprecedented health and economic crisis.

Mitch McConnell and the GOP refuse to take up the HEROES Act, passed by the House in early May to help Americans survive the pandemic and fortify the upcoming election.

Senate Republicans don’t want to extend the extra $600 a week in unemployment benefits, even though unemployment has soared to the highest levels since the Great Depression.

Even before the pandemic, nearly 80 percent of Americans lived paycheck to paycheck. Now many are desperate, as revealed by lengthening food lines and growing delinquencies in rent payments.

Trump is lying about other countries’ COVID-19 records to distract from his own disaster: report

Published

on

On Tuesday, writing for The Washington Post's "The Debrief," Anne Gearan broke down how President Donald Trump is trying to deflect from his disastrous inability to contain coronavirus by spreading false narratives about what's happening in other countries.

"In recent days, Trump has increasingly pointed to the experiences of other countries in an attempt to dilute the bad news at home and justify the largely hands-off federal response, which has included no national mandates or lockdowns," wrote Gearan. "Germany, France, Spain, Belgium, Japan, Israel, India, Australia, Brazil, South Korea, China, Hong Kong and others have been part of a presidential spin-the-globe review of trouble spots, in which Trump makes misleading claims about the U.S. record and talks up the prospects for a cure."
