The world's population suffers a COVID-19 pandemic. By September 2020 nearly 1 million people had died. These are official numbers. The real cases might be much higher, due to under-reporting in many countries. Different strategies were adopted by national governments. Neglecting what was defined by sanitarian authorities, some politicians, at the beginning of the pandemic, declared that it would be a little flu, without consequences, lighter than seasonal flues. Some politicians propagated medicines with no scientific support. In many countries and regions, people became confused. The population's reactions to these political positions may facilitate or block the virus spread. In this paper, we propose a model connecting the spreading of opinions with the propagation of a pandemic. We discuss how conflicting opinions can diffuse in the pandemic environment and the influence it has on the population's behavior; how it may cause a greater or smaller number of infected individuals.
全球人口正遭受新冠疫情的影响。到2020年9月，已有近100万人死亡。这些是官方数字。由于许多国家报告不足，实际病例可能要高得多。各国政府采取了不同的策略。在疫情初期，一些政治家无视卫生当局的规定，宣称这将是一场小流感，不会造成后果，比季节性流感更轻。一些政治家宣扬没有科学依据的药物。在许多国家和地区，人们感到困惑。民众对这些政治立场的反应可能会促进或阻碍病毒传播。在本文中，我们提出了一个将观点传播与疫情传播联系起来的模型。我们讨论了相互冲突的观点如何在疫情环境中传播以及它对民众行为的影响；它如何可能导致感染人数的增多或减少。
