Pneumonic plague, a lung disease spread mostly by rats, has death rates of close to 100per cent in humans if left untreated, according to Beijing health authorities.
None of the 46 people have shown signs of fever or other abnormal symptoms, according to the statement.
Officials said the risk of an outbreak of pneumonic plague was minimal after the two cases were confirmed last week in Beijing.
Inner Mongolia health authority reported on Sunday a case of bubonic plague, which is the most common form of plague globally and can spread to lungs and cause the more severe pneumonic plague.
