Abstract
Dengue fever is one of the common viral illnesses linked with significant morbidity and mortality. Of late, there is rapid increase in dengue cases in India. The present study aimed to known dengue seropositivity in different seasons of a year, other laboratory parameters and its geographical distribution. During the study period of 15 months 4172 patients hospitalized with probable dengue fever were included. Dengue serology was done for all cases by ELISA(J. Mitra & Co). Demographic details were taken to create geographical maps of the disease. Of the 4172 suspected dengue cases, 817 had confirmed dengue illness. Of these 817 cases, 584 showed Ns1 antigen (71.4%), 150 IgM antibody (18.3%), and 38 had both Ns1 and Ig M (4.6%). Platelet count less than 1,00,000 were seen in 566 (69.27%) patients. Dengue was noticeably more during monsoon time (June to September) of a year. Through geographical maps major clusters were noticed urban areas of Mysuru and Krishnaraja Nagara , while few clusters were also observed in Periyapatna and T Narsipura taluks of Mysuru district. To minimize the load of dengue cases and its death rate better community awareness and vector control measures need to be strengthened during monsoon especially in areas where burden of the disease is more. This study helps in early preparedness of the authorities concerned in controlling possible epidemics in future.

Following mapping of these 817 positive dengue illness cases, majority of the clusters were observed in Krishnarajanagarataluk and urban areas of Mysuru district as shown in (Map 01)
Summary
Dengue an Arbo viral disease transmitted by mosquito has rapidly spread across the globe in recent times[1]. The word “Dengue” is derived from Swahili phrase ka-dingapepo means “cramp like seizure”[2]. According to the WHO estimation, world’s two third of the population are at the risk of the disease, especially the tropical and subtropical countries. In the year 1780, Benjamin Rush in Philadelphia 1st reported dengue and described its condition as “break-borne disease”[3]. In South East Asian region, India stands as one of the seven countries reporting high incidence of dengue outbreaks that threatens the health care system. Back in 1940’s the 1st report of dengue in India was confirmed & after that more states have been reporting this illness[4]
