Background: Dengue has affected many countries globally. Two-fifths part of the world is at risk, which can be affected by dengue disease. In India, the dengue incidence has increased in the recent past and emerged as an important health problem in many states including Odisha. Dengue disease presents with atypical clinical symptoms when associated with other co-infections. Materials and Methods: A facility-based longitudinal study was carried out over a period of 1 year to determine the dengue co-infection and its outcome. The suspected cases were clinically assessed following a standard case report format and serological investigations including serotyping were carried out. Results: 33.6% samples were dengue positive of which 78.5% were positive for NS1 Ag, 26.6% positive for dengue IgM and 5.1% to both. Among the dengue positive cases, 60.9% were male and mean age was 31.52 (±17.03) years. High occurrence of cases was during May to November with maximum in August. Among the 975 dengue positives, 57 (5.8%) were found to have co-infection. Chikungunya was the most common co-infection in 71.9%, followed by herpes simplex (HSV) (7%) and other diseases. Fever was the most common presenting symptom (98.2%), followed by myalgia (91.2%), retro orbital pain (91.2%), pain abdomen (12.3%), rash/lesion (8.8%), burning micturition (5.3%), petechiae (1.7%) and pruritus (1.7%) among the co-infected cases. Conclusions: All the four dengue serotypes were found to be circulating with DEN 2 as the most predominant one. About 5.8% of dengue cases have co-infection (mainly with Chikungunya) and clinically present with atypical signs and symptoms.
