Dogs are being trained to sniff out coronavirus cases
As some states move to reopen after weeks of shutdowns, infectious disease experts say the prevention of future coronavirus outbreaks will require scaling up testing and identifying asymptomatic carriers.
Eight Labrador retrievers — and their powerful noses — have been enlisted to help.
The dogs are the first trainees in a University of Pennsylvania research project to determine whether canines can detect an odor associated with the virus that causes the disease covid-19. If so, they might eventually be used in a sort of “canine surveillance” corps, the university said — offering a noninvasive, four-legged method to screen people in airports, businesses or hospitals.
It would not be surprising if the dogs prove adept at detecting SARS-CoV-2. In addition to drugs, explosives and contraband food items, dogs are able to sniff out malaria, cancers and even a bacterium ravaging Florida’s citrus groves. Research has found viruses have specific odors, said Cynthia M. Otto, director of the Working Dog Center at Penn’s School of Veterinary Medicine.
“We don’t know that this will be the odor of the virus, per se, or the response to the virus, or a combination,” said Otto, who is leading the project. “But the dogs don’t care what the odor is. … What they learn is that there’s something different about this sample than there is about that sample.”
A similar effort is underway at the London School of Hygiene & Tropical Medicine, where researchers previously demonstrated that dogs could identify malaria infections in humans. In a statement, James Logan, head of the school’s disease control department, called canines a “new diagnostic tool” that “could revolutionize our response to covid-19.”
Logan said Tuesday that his research team expects to begin collecting covid-19 samples “within a matter of weeks” and working with the charity Medical Detection Dogs to train canines soon after. The initial goal is to deploy six dogs to airports in the United Kingdom, he said.
“Each individual dog can screen up to 250 people per hour,” Logan said in an email. “We are simultaneously working on a model to scale it up so it can be deployed in other countries at ports of entry, including airports.”
The Working Dog Center typically trains dogs, which live with foster families, at its facility in Philadelphia, but the pandemic is forcing it to adjust. To minimize social contact, the project instead is working with Labs at a K-9 training firm in Maryland, Tactical Directional Canine, Otto said.
Miss M., Poncho and six other chocolate, yellow and black Labs began the first stage of training — learning to identify an odor for a food reward — this month, she said. Next, the dogs will train using urine and saliva samples collected from patients who tested positive and negative at the Hospital of the University of Pennsylvania and the Children’s Hospital of Philadelphia.
The following step is trickier, Otto said: learning to detect the virus in a human.
“That’s going to be the next proof of concept: Can we train them to identify it when a person has it and that person’s moving? Or even standing still?” Otto said.
Exactly how covid-19 detection dogs might be put to use in the United States would depend on demands, Otto said, though no one’s talking about stationing a dog in every hospital or testing site.
If the need is lots of tests, then Penn chemists and physicists might be able to use what they learn from the dogs to create an electronic “nose,” or sensor. The goal of the Working Dog Center’s research on ovarian-cancer-detection dogs, for example, is to produce “an electronic test where thousands and thousands of samples could be screened in a short period,” Otto said.
Other settings, such as fields where the center has trained dogs to detect the eggs of invasive spotted lantern flies, call for actual canines that can quickly roam and sniff, she said.
“The exciting area is the sort of convergence with what dogs are currently doing with screening for explosives,” she said. “If we can do a similar approach for screening humans, then there will be a large interest” in using dogs to help flag people for testing, she added.
“We don’t have enough detection dogs. And if now, all of a sudden, everyone wants a covid detection dog? It’s going to be a challenge to figure out where are the priorities,” Otto said. “But there’s a lot of opportunity.”

LONDON – An ex-Muslim turned Christian evangelist has been beaten, chased by angry mobs, unlawfully jailed and even stabbed, all for the sake of the Gospel.
This is not in Afghanistan or Saudi Arabia. It is officially happening in Christian Britain.
Her name is Hatun Tash, and what has been done to her has even caught the attention of the British media.
Tash grew up in Turkey as a Muslim and became a Christian after moving to England. And being an ex-Muslim speaking out against Islam has made her a target.
She told us she has changed residences more than 50 times in the past four years because she knows Muslims are looking for her in order to kill her. One man has already been sentenced to 24 years in prison for trying.
Because of this ongoing danger, she asked that we interview her from a secret location.
Tash told us her conversion to Christ began when she learned the truth about Islam and Mohammed.
“As I read biography, it was very disturbing to me. So, the man you grew up to love and honor suddenly turns out to be like, yeah, not good, not good. And I decided, I can’t be Muslim.”
Then she learned about a very different God than the one of Islam, telling us, “As you dig into it, you get to meet with a God who is not silent or far or distant from you, but you meet with a God who loves you, who pours out himself on you. And not only that, He just puts himself on the cross and then says, ‘I love you from everlasting to everlasting, Come to me.'”
Tash began sharing this message to Muslims at Speakers Corner, in London’s Hyde Park, where speakers climb atop stepladders and vigorous debates ensue, often between Muslims and Christians.
Her preaching and criticism of Islam has sometimes enraged Muslims, and three years ago a man slashed her face with a knife. He has never been caught.
She however has been arrested unlawfully more than once. The London Police have twice paid her damages for wrongful arrests, including two years ago when she refused to leave the area where she was preaching. Tash was forcibly marched through Hyde Park, followed by Muslims celebrating her arrest. She was placed in a police van, strip-searched, and jailed.
This has not stopped Tash from going to mosques and sharing the Gospel daily.
“I would simply stand in front of the mosques, and I’d say ‘Muhammad is a false prophet. Jesus Christ is the Son of God. Tell me, what is your objections?’ Hundreds of Muslims just stop and then they want to talk to you. Sometimes you get harmed, sometimes it gets dangerous. Sometimes you end up in hospitals, sometimes you end up in people’s homes for a cup of tea,” Tash said.
“I don’t care whether people reject me or not. They need to hear the gospel,” she said.
Christian Concern’s Christian Legal Centre has defended Tash. Christian Concern’s Andrea Williams told us, “The truth is that those that have attempted to kill her have been caught on camera. The police know who they are, but they have not been arrested. She is feared by and targeted by Muslim groups because she is fearless for the gospel. She loves Jesus so much that nothing will halt her.”
Tash says she will continue to preach and continue to challenge Islam.
“Things are dangerous. Should I choose to stay silent? Like when people are spending 5,000 Pounds to buy a gun, to shoot you and shoot your loved ones? The Gospel is so glorious, I cannot be silent. And the Lord is the giver of life. So, when it’s my time, He will take me home. But until He gives me breath, we continue to preach.”

‘Christ Laid His Life Down for Me’: Greg Laurie Gives Powerful Gospel Presentation to Jordan Peterson
Christian megachurch leader Greg Laurie recently appeared on psychologist Jordan Peterson’s podcast, where he gave the professor-turned-cultural commentator a powerful presentation of the Gospel.
“When everything’s said and done, what’s more important than the afterlife?” the California-based pastor asked Peterson. “What’s more important than where we spend it? According to the Bible, I believe there’s a literal heaven, a literal hell, and I believe we choose in this life where we will spend the afterlife.”
Laurie added he’s going to spend eternity in heaven “not because I’ve lived a good life — because I failed in many ways — but because Christ laid His life down for me on the cross.”
“Coming back to Abraham, and what a picture, the son was willing to go and be sacrificed by the father,” the pastor continued, referring to the Old Testament story of Genesis 22. “[Isaac] knew what was going on: ‘Hey, Dad, where’s the sacrifice?’ ‘My son, God will provide for Himself a sacrifice.’ But Isaac made that sacrifice, too. The Son Jesus made that sacrifice for us, because He knew there was no other way that we could reach God, no other way we could satisfy the righteous demands of God. So Heaven isn’t for good people, as it’s often said; heaven is for forgiven people.”
The conversation between Peterson and Laurie stemmed from the 71-year-old minister opening up about the death of his son, Christopher, who passed away in 2008 as a result of a tragic car accident.
He described that day in July of 2008 as the “worst” day in his life. Nevertheless, Laurie said he is not without hope — because of his faith in the redemptive work of Jesus.
“I believe I’ll see my son again, because he believed in Jesus,” Laurie explained. “He won’t be in heaven because I’m his dad; he’ll be in heaven because he put his faith in Christ and he had that relationship. He’s a part of my future as well, so that gives me hope. But, also, I realize that God can allow these things in our life. I don’t know why. I can’t explain it. I don’t even try to explain it.”
Peterson, author of the new book, “We Who Wrestle With God: Perceptions of the Divine,” admitted to Laurie he struggles to intellectually reconcile a desire to perfect the earthly world with the knowledge the Christian life is heavily weighted toward considering eternity.
The famed psychologist and podcast host asked, “How do you reconcile, in your own mind, the insistence that part of the Christian moral pattern is to perfect the world and to raise the material up to the heavenly with the notion of the afterlife and immortality?”
Laurie referenced 2 Corinthians 12:2-4, in which the Apostle Paul wrote about experiencing a “third heaven,” as well as the thief on the cross next to Jesus, Who promised the man, “Truly I tell you, today you will be with Me in paradise” (Luke 23:42-43, NIV).
The pastor explained he has felt closest to God — and His promises of eternity — through life’s trials.
“God made a lot of promises,” said Laurie. “I’ve put those promises to the test, including the worst thing of all, to lose a child. And I’ve seen how God had come through for me. If He hadn’t come through for me after my son died, I would have given up preaching, for sure. Why carry on? But He came through for me.”
