[Persistence of dengue symptoms in patients in Uberaba, Minas Gerais State, Brazil].

The clinical picture of dengue is characterized by a maximum duration of 14 days despite frequent complaints of longer symptoms. This study evaluated the occurrence of persistent symptoms (> 14 days) and its impact on daily life. A hundred eighteen patients were interviewed, and the main symptoms at diagnosis were mialgia (98.3%), fever (97.5%) and weakness (95.8%). The presence of at least a persistent symptom was related by 77 (65.2%) individuals of wich 10 (8.5%) described it as intense and lasting for 30 days or more. The most persistent symptoms mentioned were weakness (58 cases), hiporexia (49) and sleepiness (40), occurring mostly in women, with odds ratio: 5.4 (IC95%: 2.3-12.3). A significant association between the persistence of the symptoms and the history of extra expenses (p = 0,02) was found, as well as a delay to return to normal activities (p < 0.001). Thus, it was verified that dengue presented a relevant impact on every day life, even after 14 days, a fact wich was associated with the presence of persistent symptoms of the illness.
