Disease severity during SARS-COV-2 reinfection: a nationwide study.

ABSTRACT:

Objective

We aimed to look at the burden of disease caused by SARS-COV-2 reinfections and identified potential risk factors for disease severity.

Methods

We used national surveillance data to collect information on all SARS-CoV-2 primary infection and suspected reinfection cases between January 2020 until early May 2021.

We collected information on case demographics, hospital and ICU admission, immunisation status and if individuals were at risk of complication for COVID-19.

Results

Deaths reported within 28 days of testing positive were 61% (95% confidence interval: 56% to 65%) lower in suspected COVID-19 reinfection than primary infection cases. In the unv
