The boy contracted the disease in Mongolia, which borders China, causing bordering countries to now be on alert for the virus which caused the Black Death. The teen died three days after eating rodent meat causing relatives and friends to be put into isolation. Earlier this month, the Inner Mongolian Chinese city of Bayan was put on a severe threat level after a local farmer contracted the virus.
The disease is a bacterial infection which spreads by living on wild rodents with both Russia and China being warned of the severe threat of the virus.
Such is its potential potency that it can kill the subject in less than 24 hours if not treated correctly.
The National Centre for Zoonotic Diseases said the boy had died in the province of Govi-Altai.
The region is on the country’s southern border thus sparking fears it could soon spread across into China.
Five districts have now been placed into lockdown in order to contain the potent virus which the Mongolian Health Ministry warned is incredibly prevalent in the mountainous regions of China.
In particular, officials pointed to the Altai Mountain which has a high rodent population.
Crucially, the mountain range spreads into four countries including Russia, China and Kazakhstan.
Senior official Dorj Narangerel warned not to eat or hunt the meat due to a potential virus outbreak.

Before the death of the 15-year-old, there had been two other reports of the plague in the country.
A 27-year-old man and his brother, 17 were in hospital in stable conditions.
In China, Bayan was placed on a level three threat warning over fears the outbreak could spark another epidemic.
A statement from the local authority read: “At present, there is a risk of a human plague epidemic spreading in this city.
“The public should improve its self-protection awareness and ability, and report abnormal health conditions promptly.”
The World Health organisation has also declared it is now monitoring the situation.
They did add the outbreak was being well handled by the government.
WHO spokeswoman, Margaret Harris said: “Bubonic plague has been with us and is always with us, for centuries.
