Characteristics and Behaviors Associated with Prevalent SARS-CoV-2 Infection

Abstract Introduction: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which causes coronavirus disease 2019 (Covid-19), has been a serious threat to global health.

Methods: We analyzed data obtained from the Covid-19 Citizen
