Interregional transmission risk of MPXV. A imported risk from endemic countries; B imported risk from current epidemic countries in 2022. The endemic and main epidemic countries were indicated by the background of brown and orange color. The orange curves represent air routes from cities in MPXV endemic countries or main epidemic countries to other cities around the world, and its opacity represents the magnitude of the imported risk transmitted by air routes. The imported risks outside endemic countries are also indicated by color of circles (from green to purple). Air routes with the number of passengers less than 500 persons from endemic countries or less than 150 000 persons from current epidemic countries per year are not displayed
