A cross-sectional study in Malaysia assessed the knowledge, attitudes, and practices (KAP) of the public regarding COVID-19. The survey, conducted online between March 27 and April 3, 2020, involved 4,850 participants. The overall correct rate on the knowledge questionnaire was 80.5%, with most participants holding positive attitudes toward controlling the virus and the government's response. Over 80% of participants avoided crowded places and practiced proper hand hygiene before the movement control order (MCO) began, though only 51.2% wore face masks. The study highlights the importance of consistent messaging from health authorities and the need for targeted health education to improve public understanding and practices. The results indicate that Malaysians generally have an acceptable level of knowledge about COVID-19 and are optimistic about overcoming the pandemic. However, there are disparities in knowledge and practices among different demographic groups. The study also notes challenges in mask-wearing, partly due to limited availability and mixed public guidance. The findings emphasize the need for comprehensive health education programs and effective communication strategies to address misinformation and improve public health outcomes. Limitations include potential sampling bias and the use of a single item to measure attitudes and practices. Overall, the study provides valuable insights into the public's response to the pandemic and underscores the importance of clear, consistent messaging and targeted health education.A cross-sectional study in Malaysia assessed the knowledge, attitudes, and practices (KAP) of the public regarding COVID-19.
