Objective:
To analyze the 2022 multiple-country monkeypox outbreak and assess its importation risk into China.
Methods:
Data was from United States Centers for Disease Control and Prevention. We described the global epidemic and calculated concentration index to measure economic-related inequality. Importation risk into China was evaluated and ranked by using risk matrix method and Borda count method, respectively.
Results:
As of July 29, 2022, of 79 countries or territories, 39 (49.37%, 39/79), 17 (21.52%, 17/79), 6 (7.59%, 6/79), 12 (15.19%, 12/79), and 5 (6.33%, 5/79) country or territories identified cases < 10, 10-, 51-, 101-, and > 1,000. There were economic-related health disparities exist in the distribution of cases (the concentration index = 0.42, P = 0.027), and the inequality disadvantageous to the rich (pro-poor). There were 12 (15.38%, 12/78), 15 (19.23%, 15/78), 6 (7.69%, 6/78), and 45 (57.69%, 45/78) countries or territories with extremely high, high, moderate, and low importation risk. United States and France ranked first with the highest Borda points of 156, and counts of zero.
Conclusion:
Of 78 countries or territories, the key attention need be paid to the United States and France, relatively. As the epidemic progresses, preparing prevention and control measures to further reduce importation risk was crucial.
