Linguistic studies on media coverage of pandemics and outbreaks in Nigeria, including the COVID-19 pandemic, Ebola, and Lassa fever, have been extensive. However, the linguistic analysis of media reports on the diphtheria outbreak remains underexplored. This study addresses this gap by examining the lexical choices employed in framing the diphtheria outbreak in Nigeria. Twenty articles from four popular Nigerian newspapers – The Punch, The Guardian, The Vanguard, and The Premium Times – were examined to discover the prevalent frames and associated lexical choices. The articles were collected between January and August 2023, a significant period marked by the resurgence of the disease and extensive reporting on its impact on victims. Using frame theory and lexical priming theory as analytical frameworks, the study identified frames such as health crisis, victim, government response, global aid and response, vaccination shortfall/hesitancy, public health awareness, past antecedent, and collaborative effort. Common lexical choices included terms like “deadly,” “surge,” and “critical situation,” which emphasize fear and urgency. This emotive tone is used purposefully to attract readers’ attention and prime them to interpret the outbreak as an urgent public health issue. Frames like Public Health Awareness and Government Response are concerned with informing the public. Several other frames, most notably Vaccination Shortfall/Hesitancy and Collaborative Effort, serve as a rallying cry. They highlight the need for increased vaccination coverage, collaboration among stakeholders, and public participation in health measures. Through framing and lexical choices, the media shapes public opinion, influences perceptions, and guides individual and collective responses to health issues like the diphtheria outbreak. The relevance of this study lies in its contribution to understanding how media framing and lexical choices impact public health communication, ultimately aiding in more effective health crisis management and public engagement strategies.
