title: Prevalence of febrile syndromes in dengue surveillance, havana city, 2007.
abstract: Determine point prevalence of febrile syndromes and compare with prevalence reported by habitual clinical and seroepidemiologic dengue surveillance system in Havana City.
  
  
  
  In October 2007, a descriptive, cross-sectional study was carried out in a representative sample, calculating prevalences of febrile syndromes and undifferentiated febrile syndromes. Chi-square analysis was used for rate comparisons.
  
  
  
  Point prevalences of febrile syndromes and undifferentiated febrile syndromes were 352.6 and 144.2 times greater, respectively, than those reported by the habitual clinical and seroepidemiologic dengue surveillance system; these differences were statistically significant (p < 0.001).
  
  
  
  Point prevalence of febrile syndromes was far greater than prevalence reported by the habitual clinical and seroepidemiologic dengue surveillance system, an indication of underreporting.
