Objective To assess the knowledge, attitude and practice (KAP) of the global general population regarding COVID-19. Design Systematic review and meta-analysis. Methods MEDLINE, Embase, CINAHL and PsycINFO were used to identify articles published between 1 January and 30 June 2021 assessing KAP regarding COVID-19 in the global general population. The quality of eligible studies was assessed. Random effects model was used to obtain the pooled proportion of each component of KAP of COVID-19. Heterogeneity (I 2 ) was tested, and subgroup and correlation analyses were performed. Results Out of 3099 records, 84 studies from 45 countries across all continents assessing 215 731 participants’ COVID-19 KAP were included in this study. The estimated overall correct answers for knowledge, good attitude and good practice in this review were 75% (95% CI 72% to 77%), 74% (95% CI 71% to 77%) and 70% (95% CI 66% to 74%), respectively. Low-income countries, men, people aged below 30 years and people with 12 years of education or less had the lowest practice scores. Practice scores were below 60% in Africa and Europe/Oceania. Overall heterogeneity was high (I 2 ≥98%), and publication bias was present (Egger’s regression test, p<0.01). A positive significant correlation between knowledge and practice (r=0.314, p=0.006), and attitude and practice (r=0.348, p=0.004) was observed. Conclusions This study’s findings call for community-based awareness programmes to provide a simple, clear and under...
