BEIJING—The northwestern Chinese region of Ningxia reported one human infection of plague, state television said late on Tuesday.

The caseload of human plague infection, a highly infectious and severe disease, is low in China, with just one in 2021 and no deaths, down from four infections and three deaths in 2020, according to data from the National Health Commission, which does not specify the types of plague for each person.
