Parts of Yumen, a city in northwestern China, have been sealed off after a local died of bubonic plague last week, reports Reuters. The 38-year-old man is said to have contracted the bacterial disease, also known as the black death, after coming into contact with a type of rodent called a marmot. Moreover, 151 residents are under quarantine after coming into direct contact with the man who contracted the disease. City officials say that they have enough rice, flour, and oil to supply all 30,000 residents for up to a month, but reports haven’t yet mentioned how long this situation might last.
