Travelers aren't at high risk for malaria. They visit cities and areas where malaria isn't usually endemic. Eradication of malaria has been a failure because we can't reach the more remote areas where humans live with it. Because there is an animal host (mosquitoes), treating a village with anti-malarials is often a temporary reprieve. There will always be mosquitos and recurrent infections to re-infect the locals after the doctors are gone.
