Health experts in China have issued a warning after a case of bubonic plague was confirmed by doctors.
A third-level alert was issued in the Chinese city of Bayan Nur – the second-lowest in a four-level system.
Local reports say the patient is a herdsman from the city, in the Inner Mongolia autonomous region, and that he is in a stable condition
A third-level alert forbids the hunting and eating of animals that could carry the plague and asks the public to report any suspected cases of plague or fever with no clear causes, and to report any sick or dead marmots.
There was also a fresh plague scare in the province of Bayan-Ulgii in neighbouring Mongolia, which shares a border with both Russia and China.
And a 15-year-old resident of Ulaankhus soum, also in Mongolia, was taken to a local hospital on Sunday after eating a marmot hunted by a dog.
The medieval disease is easily treatable with modern medicine – but left untreated, most infected will die within a week.
In the 14th Century the black death – a collection of plagues including bubonic plague – tore through the globe making it the most deadly recorded pandemic in history.
It killed 200 million people across Africa, Asia and Europe wiping out 60 per cent of Europe’s population.
Speaking to Healthline, Dr Shanti Kappagoda, an infectious diseases doctor at Stanford Health Care said: “Unlike in the 14th Century, we now have an understanding of how this disease is transmitted.
It comes after two brothers in Mongolia reportedly contracted the plague from eating marmot meat – a folk remedy for good health, the BBC reports.
A 27-year-old man and his brother, 17, are in hospital and described as “stable”.
Pansoch Buyainbat and his brother are being treated in separate hospitals in Khovd province.
