Key Points

The study aims to assess the effectiveness of targeted COVID-19 prevention measures in a correctional facility amidst policy changes.
Executed a 40-day comprehensive study in a prison environment post-policy change.
Collected 79,075 nucleic acid samples from facility entrants.
Used targeted next-generation sequencing to analyze viral strains.
Monitored the impact of external non-pharmaceutical interventions on viral transmission.
The prison outbreak occurred after two years without cases due to external intervention changes.
Continuous internal measures delayed the epidemic peak by approximately 5 days.
Identified nine distinct SARS-CoV-2 strains on the first day of widespread testing.
Notable decrease in 20× coverage of sequencing in the later stages of the epidemic (p < 0.0001).
