Keywords:
undifferentiated fever, ThaSala, Thailand, Adult, DengueAbstract
Background and objective:Acute undifferentiated fever (AUF) is one of the common presentations in a clinical setting. To identify etiologic spectrum, there is an advantage in assigning resource allocation especially for primary prevention. The etiology data of acute undifferentiated fever have been poorly characterized in ThaSala district.
Material and Method:The retrospective study design was done at ThaSala hospital from January 2011 to December 2015. Adult patients (≥18 years old) who presented with acute undifferentiated fever at inpatient setting were included. The 10th revision of the International Statistical Classification of Diseases and Related Health Problems was used to categorize and collect the data.
Results : There were 1,838 recorded visits (female 53.9%, male 46.1%). The Patients’ median age was 33 (IQR 23-47) years. The study revealed the etiologies of acute undifferentiated fever to be dengue infection (71.1%), unspecified fever (16.9%), scrub typhus (12.0%), and influenza (0.1%). There were 311 patients (16.9%) with left unknown etiology of acute undifferentiated fever in spite of undergoing proper investigations.
Conclusions : The most common cause of acute undifferentiated fever was dengue infection which was found in early adulthood. According to narrow etiology spectrum, the complete study data were in doubt. The further study should be done prospectively within proper duration.
