It is still possible to get the disease today. So to prevent it, a person should keep away from places where there are a lot of rodents. A good news about the plague is once a person is infected and the person luckily recovers, the person becomes immune. If a person is infected, quarantine measures should be enforced to keep the disease from spreading. If the disease is noticed early enough, modern antibiotics can treat it easily.
Fire can also drive away the disease.
Pesticides should be used alot on plague areas to kill the fleas. These two, however, are only used in adults, so for infants, the antibiotic Kanamycin is used.
