Smallpox used to kill millions of people every year. Here's how humans beat it.

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.

Raton, a town once surrounded by eight coal mines, now has a main street of boarded-up buildings. There is reason for optimism as the town diversifies its local economy, betting on "a mix of small manufacturing businesses, health care and specialty services, and hospitality for travelers" to endure the sudden decline in mining revenue. Its calculated revitalization may hold lessons for other towns.

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.

Twenty years ago, five, poor, rural counties sued the state of North Carolina for failing to provide students with a good education, and won. In 1997 the Chief Justice Supreme Court judge ruled in favor of the plaintiffs in the case known as Leandro v. State. However, the decision wasn’t really enforced by the government, and until 2017 a court appointed agency was hired to investigate the state. “Leandro sets the bar but you still need to have elected officials, school officials and court officials willing to uphold it,”

Rather than send local residents to city-run testing sites in the East Bay of California, clinics in East Oakland are now running their own testing sites to better serve their community. Although one of the sites has already tested nearly 100 people and residents who are underinsured or uninsured can be tested for free, some believe the effort should have started much sooner.

The state of Vermont has been able to keep COVID-19 cases to a minimal, at least in part by focusing on offering preventive protections for the most at-risk and vulnerable – such as the unhoused. The state's response has included "state-supported housing for the homeless, hazard pay, meal deliveries, and free, pop-up testing in at-risk communities," all of which prioritize high-risk populations rather than those who can easily self-isolate at home.

In an effort to help get accurate information to the communities who are being disproportionately impacted by the coronavirus pandemic, a program called Live Chair Health has started to train barbers "on chronic issues that disproportionately affect Black communities" and teach them "how to have conversations with their clients about the diseases." Aside from providing COVID-19 information, the initiative has helped patrons access primary care and address other medical issues such as high blood pressure.

Genetic genealogy's use in criminal cases has gone mainstream. As the cases of three murder victims in Indiana illustrate, the science of DNA evidence combined with genealogical research and detective work is rapidly ramping up, from a hobby to a curiosity and now to a major commercial and criminal-justice opportunity. Hundreds of missing persons have been identified from decades-old remains, or murder suspects identified from old biological evidence in cold cases. By creating a family tree of the victim or suspect, investigators can zero in on an identity more quickly and inexpensively than ever.

To mark the 100th anniversary of the Tulsa Race Massacre, in which a white mob killed hundreds of Black residents and destroyed the thriving neighborhood of Greenwood, the Centennial Commission supported a number of initiatives to learn from the past and build a better future. At the base of an ancient elm tree that witnessed the massacre, Up With Trees distributed 100 elm seedlings to children to plant around Tulsa. The commission convinced state education officials to develop a new curriculum on the massacre for K-12 students.

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.
