Abstract
Yunnan unexplained sudden death is mostly cardiac sudden death caused by malignant arrhythmia, which is a special endemic disease that seriously threatens the health of people in the disease area, and is one of the important public health problems in Yunnan Province. The epidemiological characteristics of Yunnan unexplained sudden death are characterized by a high incidence of young and middle-aged people, and a clear clustering of ethnic groups, families, and villages. The etiology of this disease is not yet fully understood, and the main etiological studies include Trogia venenata poisoning, enterovirus infection, and hereditary heart disease, and hypothesis of the etiology of Keshan disease. After the implementation of comprehensive intervention measures such as health education based on abstinence from Trogia venenata, improving of production and living conditions in the disease area, and strengthening of health monitoring of the population in the disease area, the incidence has shown a significant downward trend in recent years.
