Seasonal, Regional and Demographic Trends in Patients with Acute Undifferentiated Fever in Northern India

ABSTRACT

Introduction: Acute Undifferentiated Fever (AUF) has a myriad of etiologies most common of which are Vector Borne Diseases in a country like India. The etiology and diagnosis of AUF is driven by the regional disease burden, seasonality of infectious diseases, spectrum and severity of disease, availability of diagnostics and access to health care facilities. Methods: A twelve-month prospective study was conducted at our centre to determine the commonly occurring causes of AUF. Monthly incidence of each of the common etiologies was noted and a graph was plotted to understand the seasonal distribution of each disease. Other parameters including age, gender, occupation and regional distribution were also studied. Results: The mean age (±SD) of the population in the present study was 33.16 (±15.88) years. Our study established that Scrub Typhus, Dengue fever and malaria were the most common reasons for AUF. The maximum incidence of AUF was between the months of June to October, peaking in the month of August. Urban population, younger age and males were more affected by AUF. Haryana followed by Punjab and Chandigarh had the highest regional burden of disease. Conclusion: It is imperative that we understand the seasonal and regional trends of AUF so that we can plan the resource allocation. Identifying the population at risk and timely intervention at Community level may help to reduce disease transmission.
