At the time of writing, the tally of confirmed novel coronavirus (COVID-19) cases worldwide has exceeded 26.6 million.1 The United States has become the global epicentre since April 2020, and now it is accounted for nearly one-quarter of the world's total cases. Some studies suggest that health-related issues can cause anxiety which may lead to increased public attention, typically manifested by online information search.2,3 Along the same lines, given the substantial regional disparities of COVID-19 case severities across states in the United States, the relationship between regional case severities and the public interest emerges as an imperative for COVID-19–based public health studies.
