An example of this is dengue fever. There are parts of the world where dengue fever is endemic, meaning that there are mosquitoes that are carrying dengue fever and transmitting it from person to person. But we also see imported cases and imported outbreaks in parts of the world where a disease is not endemic. There was an outbreak in the Big Island of Hawaii where somebody, unknown, must have come in with dengue fever, got bitten by mosquitoes, and then there were local chains of transmission where those mosquitoes then bit other people, they got dengue fever, and so on and so on. In this case, dengue fever is not endemic in the Big Island, however, there was an outbreak due to an imported disease with subsequent transmission.
