摘要

Dengue virus infection has varying clinical manifestation ranging from asymptomatic infection to life-threatening hemorrhagic fever and dengue shock syndrome. There are a number of rare presentations that were reported in the last outbreak in 2017. However, long-term consequences of dengue fever were reported worldwide, but Sri Lanka is not an exception. One of the long-term displays is post dengue fatigu e syndrome (PDFS). Post dengue fatigue syndrome (PDFS) is not an uncommon occurrence. It comprises of a variety of symptoms complex ranging from fatigue, muscle weakness and variable neurological abnormalities which have been reported in various parts of the world. We conducted the descriptive prospective study at Batticaloa Teaching Hospital, Sri Lanka. In this study, we collected data from the patient with serologically confirmed dengue infection. One month after discharge, follow-up study was conducted through telephone interview and validated fatigue questionnaire was filled. Fifty-two serologically positive patients were agreed and participated in this study: 21 (40.38%) males and 31 (59.61%) females. Out of the 52 patients, 9 had PDFS: 5 (55.5%) males and 4 (44.4%) females. Almost all PDFS patients were complained of muscle weakness, muscle pain and poor concentrations.
