On November 12, 2019, It was announced that two people from the Chinese province of Inner Mongolia were diagnosed with pneumonic plague. They received treatment in Chaoyang District, Beijing, and authorities implemented preventative control measures. Later in November, a third case of plague was confirmed. A 55-year-old man was diagnosed with bubonic plague after eating wild rabbit in Inner Mongolia. The region's health commission says it has no evidence to suggest that this case is linked to the previous two. By the end of November, a fourth case was confirmed. Chinese health authorities reported a fresh case of bubonic plague in the country's northern Inner Mongolia region, bringing the total number of reported plague cases originating from Inner Mongolia to four.
