Do patients infected with human coronavirus before the COVID-19 pandemic have less risk of being infected with COVID-19?

This is the authors' abstract. We don't add key points for this paper.

Although seasonal human coronaviruses (HCoVs) have long been recognized as respiratory tract viruses, the newly identified SARS-CoV-2 caused a pandemic associated with severe respiratory failure. We aimed to evaluate the incidence of COVID-19 infection in patients diagnosed in three tertiary teaching hospitals, both with and without prior confirmed HCoV infection, and to compare these cohorts in terms of COVID-19 contraction.
