This study aims to provide a comprehensive analysis of the messages presented by the COVID-19 posters. It examines the verbal and visual elements of two selected American awareness posters published on the official Facebook page of the U.S. Department of Health and Human Services (HHS) in 2021 and 2022. Since these posters have both visual and verbal components, the objective of this qualitative study is to investigate the semiotic resources utilized in the COVID-19 precautionary posters via employing a multimodal perspective. It implements a descriptive qualitative approach by utilizing diverse analytical tools: the Social Semiotics Approach (Kress and van Leeuwen, 2001), the Multimodal Critical Discourse Analysis Approach (Machin and Mayr, 2012), and the Reversal Theory (O'Shaughnessy, J. & O'Shaughnessy, N.J., 2004). It examines the contribution of visual and textual resources to raise awareness among people about the significance of preserving some tools for protection. Hence, this study demonstrates the integration of verbal and visual communicative modes to spread awareness among citizens according to their cultures.
