RESULTS: Out of the 1135 IP & OP patients, 517 were males (45.5%) and females were 618 (54.44%). Predominant age group who presented with symptoms and got tested was 21-30 years with 265 cases (23.34%) and coinfection rate was highest among 31- 40 years age group with 14.94 %. The total no. of dengue positive cases were 273 (24.05%) and chikungunya were 79 (6.96%). The coinfection for dengue and chikungunya was found to be 13.3% (151 cases).
