                        In a pilot study at the University of Helsinki, dogs trained as assistants in medical diagnosis learned in just a few weeks to distinguish (urine odor) patients with COVID-19 from healthy participants in the experiment, writes DW.

                            "We were pleasantly surprised at how quickly the dogs learned to distinguish the new odor," said Anna Heilm-Bjorkman, an associate professor at the Faculty of Veterinary Medicine at the University of Helsinki. Dogs identify the odor with an accuracy close to that of PCR tests, she added.

                Promising results from Finland will also serve other teams that train search dogs to get involved in the fight against COVID-19. The German Assistant Dog Center says they need more information on whether training with the virus is safe for humans and animals. "Virologists have advised us not to do it - in the end we know too little about the virus so far," said Luca Barrett of the organization.

It is not yet clear which substance in the urine helps animals recognize the presence of Kovid-19. The virus affects not only the lungs but also the blood vessels, kidneys and other organs. Probably this is how the smell of patients’ urine changes, which helps dogs respond to the disease.

                        <b>Dogs recognize malignant tumors</b>

“According to a study, dogs recognize a 93 percent chance of leukemia and a 97 percent chance of lung cancer,” explains Barrett. Animals can also identify other cancers, including skin, colon, ovarian and prostate cancers.

                Dogs also recognize Parkinson's disease - years before the first symptoms of the disease, which is extremely helpful for early diagnosis. Animals also train to identify malaria. At the moment, however, they know 7 out of 10 infected, which is not enough.



                        <b>Valuable helper in the fight against COVID-19</b>

Currently, few animals and their owners work in hospitals, and on a voluntary basis. Classical medicine and health insurance funds are largely skeptical of this method of early diagnosis.
If the findings in Finland are confirmed, search dogs could be a valuable helper in the fight against the new coronavirus. According to Luca Barrett, they can help prevent the spread of the infection at football matches, major events or at airports. And not just to check passengers. Search dogs can crawl the planes before passengers board to determine if there is a coronavirus on board the machine.
