摘要:"Introduction: Japanese encephalitis (JE) is one of the most common causes of Acute Encephalitis Syn-drome in many states of India. Od-isha is a major agricultural state of India. This present study was done to explore the knowledge of ASHA about JE and factors associated with their knowledge. Methodology: This cross-sectional study included 400 ASHA workers from different villages of Ganjam districts. Results: The mean knowledge scores of ASHA who has been in service for more than 5 years was found to be 60.88 ± 15.76. Partici-pants obtained highest scores on the questions that addressed about breeding place, biting habits of vec-tor and availability of vaccine in Odisha but had below average scores for questions that focused on treatment of Japanese Encephalitis. Conclusion: ASHA knowledge score to certain variables were not desira-ble. However, receipt of recent train-ing in vector borne diseases, num-ber of years as an ASHA significant-ly affected knowledge scores in good direction. Further community-based studies are recommended on this topic in Odisha.
