Frankfurt Airport malaria outbreak rare, but experts warn of delayed symptoms

In the shadow of one of Europe's busiest transit hubs, a single mosquito carried across an ocean in someone's luggage has reminded Germany that borders mean little to the natural world. Since July, eight people near Frankfurt Airport—most of them ordinary workers going about their days—have contracted malaria tropica, and three have died. The event is rare by any measure, but it speaks to the quiet, persistent ways in which a deeply interconnected world redistributes risk, and to the enduring importance of medical vigilance even in places where a disease has long been considered absent.
