Fever of unknown origin (FUO) is a challenging problem worldwide. FUO, as defined by Petersdorf and Beeson in 1961  , includes illness persisting for 3 weeks or more, occasional episodes of a fever 38.3°C or more, and an unclear cause upon examination after one week of hospitalization. Recently, only one retrospective study of FUO have been conducted in the south China, but there has been no good data about FUO in the north China, especially in the top-level general hospital. Based on these considerations, a 10-year retrospective study among patients with FUO in a 3100-bed teaching hospital in northern China was conducted to explore the geographic profile of FUO.
We conducted a retrospective chart review of all patients admitted to the Chinese general hospital, Beijing, China, between January 2001 and December 2010 who were diagnosed as having FUO in their admission and/or discharge diagnoses. There were 918 patients with prolonged fever fulfilling the Petersdorf and Beeson of FUO criteria. During the ten-year period, 1,002,828 patients were hospitalized, and percentage of FUO was 0.09% (918/1,002,828) in our hospital.

Our findings suggest that the spectrum of diseases causing FUO in the Chinese people is characteristic. The infections were the predominant cause of FUO (38.9%) in the current study, which was lower with the findings of previous studies (49.4% -52.6%). Collagen vascular disease and neoplasm also was the more common cause of FUO. And the miscellaneous diseases and undiagnosed FUO accounted for 8.9% and 6.5% of the samples separately.
