Background: In a public health crisis, knowledge and understanding of disease transmission modes, fundamental hygiene concepts, and procedures are critical for designing effective control measures. The purpose of this research was to assess the Bangladeshi population's Knowledge, Attitude and Practice (KAP) towards COVID-19.

Methods: A series of questions about the KAP of the population about COVID-19 were asked in this cross-sectional study, which was conducted among the general population of Bangladesh over the age of 15, and participants' demographic characteristics and source of information about COVID-19 were recorded and analyzed.

Results: Despite the fact that the majority of respondents (more than 60%) had a positive attitude about COVID-19, 70% of those questioned in Bangladesh had insufficient understanding and preventative actions. This latter discovery is promising and suggests a potential therapeutic strategy. Male and less educated respondents reported inadequate COVID-19 preventive methods, as well as a lack of understanding about signs and symptoms and transmission. The findings revealed a substantial link between knowledge, attitude, and practice among women of a certain gender, age, and education level. Male gender, non-healthcare-related jobs, single status, and a lesser degree of schooling were all substantially correlated with poorer knowledge scores, according to multiple linear regression analysis.

Conclusion: The present study revealed a high attitude among the study population towards COVID-19 but a poor response on knowledge and preventive practices, which can be enhanced by awareness campaigns and proper planning.
