This paper examines the impact of the COVID-19 pandemic in Yucatán, Mexico, with a focus on the vital role of health communication amid uncertainty. Drawing on 21 in-depth interviews, the study explores how public perceptions of the virus were shaped by government messaging, media narratives, and circulating rumors—often rooted in broader social and political tensions. The pandemic has deepened existing structural inequalities, disproportionately affecting vulnerable populations, particularly the rural Mayan communities. Adopting a critical medical anthropological perspective, the paper highlights how colonial legacies continue to influence health policy, access to reliable information, and collective responses to crisis and uncertainty.
