The Plague Can Still Kill

According to a National Geographic article (http://news.nationalgeographic.com/news/2011/10/111012-plague-black-death-yersinia-pestis-genetics-nature-health/ ) the Black Death still exist. The DNA of the plague has not changed much in 600 years. The gene Yersinia pestis aka y. pestis still is causing epidemics in the world today. The disease is most common in U.S., Madagascar, China, India, and South America. It travels much the same way as it did in the 1300's, by fleas and rodents . In today's modern science the disease is easily treated and many are cured. However The slow change in the y.pestis gene is helpfully to us because we could create a vaccine that may help prevent the plague from happening at all. Unlike the flu which genome is constantly changing a vaccine against the plague could be easily made and unchanged. Also since the change has been slow we have been able to create very good antibiotics and treatments which may be deveolped futher with the help of cracking the genome.
