Clinically meaningful phenotypes among SARS-CoV-2 reinfections: Informing prevention strategies for future pandemics.

Objective: Rapidly phenotyping patients can inform public health action plans in new pandemics. This study aimed to derive meaningful SARS-CoV-2 reinfected patients' phenotypes based on easily-available patient data and explore key epidemiological factors of reinfections.
