'Bubonic Plague' ... New Pandemic Could Threaten Whole World

China has sent an alert to the whole world after it reported  a suspected case of the bubonic plague in Bayannur, in the northern Inner Mongolia Autonomous Region.

According to the Bayannur city health commission, "the plague was diagnosed in the herdsman on Sunday, and he was in stable condition undergoing treatment at a hospital."

"The disease, which caused the Black Death in the Middle Ages, is caused by the Yersinia pestis bacterium and is transmitted by fleas that become infected by rodents," according to the New York Times.

The symptoms of the disease appear after an incubation period of one to seven days as lymphadenitis develops in the drainage lymph nodes, with the regional lymph nodes most commonly affected.

"Swelling, pain, and suppuration of the lymph nodes produce the characteristic plague buboes," WHO explained.

Bubonic plague in history

During the Middle Ages, human beings have a bad memory with that disease, which claimed millions of lives in the 14th century as it resulted in "Black Death."

The disease is expected to have originated somewhere in Asia, spreading through China and India, before killing of an estimated two-thirds of the European population in the 1340s and 1350s.
