Why This Matters: COVID-19 detecting dogs could be immensely helpful in rooting out the disease in places where it might otherwise be hard to detect, such as sporting events, airports to find the virus on surfaces, and border crossings, and places where early detection is important, like nursing homes and retirement communities, and by helping to screen people within the medical care sector who test positive so as to avoid unnecessary quarantines for those who have been exposed. The sooner we can detect that a person has contracted COVID-19, the sooner we can keep everyone else safe.
Dogs Can Detect Many Health Conditions
Dogs are able to detect many diseases effectively because their sense of smell is far superior to that of humans — we have about 5 million olfactory cells, but dogs have hundreds of millions more — a 125 million for dachshunds and 220 million for sheepdogs. Plus, dogs inhale much more often so they are constantly supplied with new odor particles that they can quickly discern with their olfactory cells.
According to researchers, some diseases, like cancer and diabetes, for example, can be detected by trained dogs. Researchers have found in one study that dogs can detect breast cancer with a 93% probability and lung cancer with a 97% probability, and other cancers too, just less reliably. Unfortunately, dogs with this training are not readily available, but they could be, but first, the researchers must determine whether the training with the aggressive virus is dangerous or not for humans and dogs.

Because of this, state authorities have implemented a variety of restrictions to preserve their dwindling trout populations, leaving recreational fly fishers in the lurch. Why This […]
Marine scientists are eagerly investigating a 100-pound opah fish, or “moonfish,” that washed ashore in Oregon last week. The deep-sea fish usually makes its home in temperate or tropical waters, raising questions about how it came to be so far north. According to the National Oceanic and Atmospheric Administration (NOAA), not much is known about the fish, which has red […]
(Parts of this story are reprinted with permission from the World Wildlife Fund) High-profile TV coverage of tigers in captivity may give the impression that breeding tigers in captivity is the only way to save the species, but that’s far from true. Globally, there are some legitimate conservation breeding programs for tigers that are important […]
