BEIJING (AP) — While China appears to have reduced coronavirus cases to near zero, other infectious threats remain, with local health authorities announcing a suspected bubonic plague case in the Inner Mongolia Autonomous Region.

Authorities in the Bayannur district raised the plague warning on Sunday, ordered residents not to hunt wild animals such as marmots and to send for treatment anyone with fever or showing other possible signs of infection.

The case was reported at a people’s hospital in Urad Middle Banner, according to state-run Xinhua news agency.

Xinhua reports that the third-level plague warning for prevention and control will last until the end of the year.

Plague can be fatal in up to 90% of people infected if not treated, primarily with several types of antibiotics.

Pneumonic plague can develop from bubonic plague and results in a severe lung infection causing shortness of breath, headache and coughing.
