The animals that sniff out TB, cancer and landmines

Hospitals across the United States are trying, in systematic ways, to reduce the risk of infection and other preventable dangers that can leave patients in worse shape after their stay. Some of the approaches include limiting entrances and exits during surgeries and administering antibiotics in a timely manner.

In many poor countries, counterfeit medicines are an enormous problem. A quarter-million malaria deaths each year might be prevented if the patients were treated with real drugs instead of fake ones.

An app that uses A.I. to scans lung X-rays is helping two hospitals in rural and remote parts of India to identify cases of tuberculosis that they otherwise would have been likely to misdiagnose. Medical professionals caution that the app is not a replacement for a clinician's diagnosis but say when used in conjunction with a clinical assessment, the interpretation of a chest X-ray is likely to be more accurate.

The South African Centre for Infectious Disease Surveillance is piloting a program to use smartphone technology to report and respond to infectious disease outbreaks. The program trains community members to recognize signs of infectious diseases, such as vomiting and diarrhea, and report them through their smartphones. These reports are relayed to a team of specialists who track the location and frequency of these reports to determine if an outbreak of disease is occurring and respond accordingly.

In the Greater Yellowstone Ecosystem, where more bears and more people are increasingly occupying the same general space, the Montana Bear Education Working Group is prepared. By holding workshops and events to teach locals how to interact with bears, carry bear spray, and adopt habits to minimize potential conflict, the group reached over 20,000 people last year and continues to educate more people.

In countries like Cambodia, Angola, and Mozambique, rats are saving lives by detecting untriggered land mines. An international nonprofit, Apopo, provides funding a training and works with local organizations to operate at the local level. The rats are light enough that they don’t trigger the explosives and can cover up to 2,000 square feet in just 20 minutes – something that would take a human up to four days to complete.

In the wake of more than 100 forest fires in Maule, Chile, hundreds of burned acres of forest are being replanted by three Border Collies named Das, Olivia, and Summer and an organization called Pewos. The dogs bound through miles of terrain with special backpacks that release native seeds to regrow the area. So far the dogs have worked in 15 forests in the region and plants are starting to come back.

The coronavirus pandemic swept the nation at a time when many would be going to polling stations to cast their votes in primary elections, but vote-at-home practices are providing a solution for this civic inconvenience. Oregon, Washington, Colorado, and now Utah have all implemented statewide all-mail election campaigns that not only improve voter turnout, but also cost less to taxpayers than only relying on in-person polling booths.

An initiative on the Moscow metro system has posters on the train featuring cats and dogs that are looking for a home. Known as the “Tails and Paws” train, these animals come from 13 animal shelters in the city and riders can use their phone to scan the poster to learn more about the animals up for adoption. “It’s about forming a new culture of responsible attitude to animals,” says one of the workers at a shelter.

Teams of Community Direct Distributors (CDD) are leading drug distribution campaigns to prevent and eliminate neglected tropical diseases in hard-to-reach, rural areas. These CDDs are members of the community they serve and are trained to educate the locals on disease prevention and administer the drugs themselves. With the CDDs’ help, several states have already eliminated some diseases and greatly reduced the spread of others.
