The World Health Organization (W.H.O.) is claiming that an outbreak of the deadly and extremely transmissible bubonic plague in China is being “well managed” by Beijing, and is no cause for alarm, according to Breitbart News.

Officials in the city of Bayannur, in the Chinese region of Inner Mongolia, issued an official warning after a herdsman reportedly contracted the deadly disease.

Since 2009, only eleven people have died of the plague, also known as the Black Death in the Middle Ages.

Symptoms of the bacterial infection, which is mostly spread by rodents, include a fever, swollen lymph nodes and feeling weak.

W.H.O. spokeswoman Margaret Harris has told the BBC the latest outbreak is absolutely no cause for concern as the Chinese Communist government has the matter well in hand. She said:

“Bubonic plague has been with us and is always with us, for centuries. We are looking at the case numbers in China. It’s being well managed.”

“At the moment, we are not considering it high risk but we’re watching it, monitoring it carefully.”

More from Breitbart News:

There were four reported cases of plague in people in the same region last November, including two cases of the deadlier pneumonic plague. On that occasion the Chinese government blocked the release of all details about the patients.

Chinese news agency Xinhua says Mongolia confirmed cases last week – brothers who had eaten marmot meat in Khovd province.

The agency called on the public to report any “ill or dead marmots and other animals,” and report suspected plague cases, “high fever patients with unknown reasons” and “patients dying from sudden deaths.”
