Data collection on COVID-19 outbreaks in closed settings: long-term care facilities, version 2.1

The main aim of this activity is to collect information on the severity of breakthrough COVID-19 infections in outbreaks at long-term care facilities (LTCFs) and to obtain an estimate of relative risk of infection for vaccinated residents and staff members in these settings, by SARS-CoV-2 variant, vaccine product and number of vaccine doses. This activity is not intended to capture all outbreaks, generate comparative statistics, or obtain a national/sub-nationally representative sample.
