          The prairie dog died at the Kautzer home a few days later, but not
        
        
          before he’d bitten Schyan’s finger. Schyan developed a fever of 103°F
        
        
          (39°C), and fluid-filled bumps appeared on her skin. Kautzer took her
        
        
          daughter to the doctor. Two days later, Schyan was admitted to the
        
        
          hospital. Doctors eventually diagnosed Schyan with monkeypox, a
        
        
          viral disease related to smallpox that had never been seen in the United
        
        
          States before it sent Schyan to the hospital. Schyan’s parents—and
        
        
          Chuckles, the other prairie dog—both got mild cases of monkeypox as
        
        
          well. All recovered completely.
        
        
          CDC disease detectives quickly traced the outbreak to a batch
        
        
          of several hundred infected rodents shipped from Ghana to a pet
        
        
          distributor in Texas. The distributor—who did not know the
        
        
          animals were sick—sent the rodents to Illinois. There, a pet dealer
        
        
          housed them with American prairie dogs, which are often sold as
        
        
          pets, like the ones the Kautzers bought. With no natural immunity
        
        
          to monkeypox, the prairie dogs quickly caught the disease from the
        
        
          African rodents and became ill. When people purchased the prairie
        
        
          dogs as pets, the animals and the people got sick too. By the end
        
        
          of the outbreak, seventy-one people in six midwestern states had
        
        
          developed monkeypox. All had contact with infected prairie dogs.
        
        
          Several were hospitalized.
        
        
          Two strains of monkeypox circulate in remote areas of central and
        
        
          West Africa. The most dangerous strain kills up to 10 percent of those
        
        
          infected. The milder strain is the one that reached the United States.
        
        
          To prevent a widespread epidemic, US health officials quarantined
        
        
          people and animals that had been exposed to the monkeypox. They
        
        
          also gave the smallpox vaccination to vets, health-care workers, and
        
        
          others at high risk of infection.
        
        
          If someone had released just one infected prairie dog into the wild,
        
        
          monkeypox could have spread to millions of American prairie dogs
        
        
          and other wildlife such as mice, squirrels, and porcupines. The disease
        
        
          could have decimated wildlife and spread to people. To prevent another
