Background:COVID 19 is a highly infectious disease transmits from human to human through respiratory droplets. Remarkable steps have been taken by the Indian government to restrain the spread of the deadly virus. Since nursing students are valuable assets in the fight against the lethal virus, they should be endowed with adequate knowledge. Objective:The objective of the current study is to compare the knowledge, attitude, and practice of the nursing students of Odisha and West Bengal towards COVID 19. Methods: A cross-sectional web-based survey was carried out among diploma, bachelor, and master degree nursing students of West Bengal and Odisha from 12th June to 20th June 2020. A 25 item self-structured questionnaire was applied to assess the knowledge, attitude, and practice (KAP) among the nursing students. About 1220 students submitted their responses through the online portal (Google form). Descriptive statistics were used for demographic variables, whereas Independent samples t-test and one-way ANOVA were applied for comparison of KAP scores based on demographic characteristics at 0.05 level of significance. Result:Among the nursing students 64.8% had good knowledge (10.63+ 1.27), 91.15% had positive attitude (3.93+ 0.743) and 99.5% had good practice (4.02+ 0.408). Comparison of KAP scores revealed that females had higher knowledge (9.34+2.24) and attitude (3.78+ 0,92) as compared to the male. It was also found that nursing students of Odisha state had greater knowledge and practice in contrast to the students of West Bengal, with a significant difference. No significant difference was found in the attitude scores between the nursing students based on current residence(p>0.05). Conclusion: The current study revealed that the majority of the students have good knowledge, a positive attitude, and good practice. But still, a gap in the knowledge was discovered; amonga few students, which require careful attention.
