We report a study on mathematical literacy with special emphasis on health literacy. In particular, we identify and characterize the mathematical competencies that a citizen needs to interpret the official information on the COVID-19 pandemic as experienced in Mexico. To achieve this, we analyze the daily reports on the pandemic issued by the Mexican Ministry of Health, using the framework of mathematical competencies as a theoretical lens. Our results show that there are five necessary competencies to interpret the official information: mathematical communication, mathematical representation, mathematical symbols and formalism, mathematical modeling, and mathematical reasoning competency. After characterizing and illustrating these competencies, we close the paper with a reflection on the importance of mathematical literacy in a pandemic world.

我们报告了一项关于数学素养的研究，特别强调健康素养。特别是，我们确定并描述了公民在解释墨西哥所经历的有关 COVID-19 大流行的官方信息时所需的数学能力。为了实现这一目标，我们使用数学能力框架作为理论视角，分析了墨西哥卫生部发布的关于大流行的每日报告。我们的研究结果表明，解释官方信息有五种必要的能力：数学交流能力、数学表示能力、数学符号和形式主义能力、数学建模能力和数学推理能力。在描述和说明这些能力之后，我们以反思数学素养在大流行世界中的重要性来结束本文。
