A suspected bubonic plague case in the Bayannur district of the Inner Mongolia Autonomous Region of China has been reported by local officials.
Residents were told not to hunt wild animals such as marmots and that anyone with fever or other possible signs of infection should seek treatment, CBS News reported.
Plague can be treated with antibiotics. If not treated, plague can be fatal in up to 90 percent of cases.
While largely eradicated in China, there are still occasional cases in the country. The last major known outbreak was in 2009 in the town of Ziketan in Qinghai province on the Tibetan Plateau, CBS News reported.
