Emerg Infect Dis. 2009 Nov;15(11):1805-8. doi: 10.3201/eid1511.091157.

Abstract

We studied 1,432 febrile travelers from Sweden who had returned from malaria-endemic areas during March 2005-March 2008. In 383 patients, paired serum samples were blindly analyzed for influenza and 7 other agents. For 21% of 115 patients with fever of unknown origin, serologic analysis showed that influenza was the major cause.
