Abstract
Background: Arboviruses are becoming a global public health menace. The common diseases worldwide caused by arboviruses are dengue, chikungunya, and Zika. This study aims to determine the prevalence of these three arboviral infections in patients with acute febrile illness at a tertiary care hospital in Kashmir, North India. Materials and Methods: A total of 812 blood samples were collected and tested for anti-dengue, anti-chikungunya immunoglobulin M (IgM), and dengue nonstructural protein 1 antigen by enzyme linked immunosorbent assay. Molecular testing of these samples was also done to detect dengue, chikungunya, and Zika viruses by using the CDC Trioplex real-time PCR assay. Results: The prevalence of diseases found among the studied patients was dengue 105/812 (12.93%) followed by chikungunya 17/812 (2.09%), and 3 cases (0.37%) were positive for both dengue and chikungunya; however, no case of Zika was detected. Interestingly, we found that only individuals that had a history of travel to different destinations within the country were positive for these viruses. Most affected cases were males 105/812 (12.93%) compared with females 20/812 (2.46%). Dengue serotyping results indicate that Dengue virus-1 was the most commonly found serotype. The most common symptoms in patients positive for dengue and chikungunya were fever, intense fatigue, myalgia, arthralgia, retro-orbital pain, anorexia, conjunctivitis, and skin rash. Conclusion: This study showed that dengue, chikungunya, and Zika viruses are not prevalent in the indigenous population of Kashmir. However, screening for these agents is required in people who have recently traveled outside Kashmir and have symptoms of acute febrile illness.
