Dengue: A Neglected Disease of Concern

Background Dengue fever, more prevalent in Asia, is a highly neglected vector-borne disease. It has a varied presentation ranging from common fever to atypical presentation as encephalitis. This study aimed to analyze the demographic and clinical profile of dengue patients admitted to a tertiary care center in Tamilnadu. Methodology This retrospective study was performed by collecting patient data from the medical records department for the years 2012 to 2014. A total of 150 patients with 50 patients from each year were selected. The patient's demographic data, clinical profile, management, and outcome were noted. Patients were divided into three groups as per the World Health Organization's 2009 classification. Results Most dengue cases occurred from October to December (70.7%). The number of male and female patients was almost equal (77 [51.3%] and 73 [48.7%], respectively). The middle-aged group (21-40 years) was commonly affected (54%). The mean age was 29 +/- 13.20 years. Fever was the most common symptom (100%), followed by lethargy (81.3%) and myalgia (60.7%). Overall, 10% of patients had comorbidities such as diabetes, hypertension, and ischemic heart disease. Moreover, 22.7% of patients had dengue with warning signs, and severe dengue was seen in 19.3% of patients. A significant difference was noted in the total count, comorbidities, serositis, and the duration of hospitalization between the groups. No mortality was recorded in the study population. Conclusions Dengue is very common in the middle-aged group. Patients with severe dengue had significant leucopenia, several comorbidities, and serositis. The mortality can be reduced to <1% and even zero in severe dengue according to our study with close monitoring and supportive care.
