Overview

Genomic surveillance reveals multiple viral introductions primarily from Europe in metropolitan COVID-19 cases, highlighting widespread undetected community transmission.

Key Points

To characterize the introduction dynamics, diversity, and early transmission pathways of SARS-CoV-2 during the spring 2020 metropolitan outbreak.
Analyzed viral genome sequences from 864 SARS-CoV-2 cases during the spring 2020 outbreak in the New York City metropolitan area.
Integrated patient epidemiological records, including travel history and known exposures, with phylogenetic comparison against global viral sequences.
Most analyzed cases lacked recent travel history or documented exposure, showing genetically linked viral variants distributed widely throughout the metropolitan region.
Global sequence comparisons revealed that early regional viral introductions originated predominantly from European lineages rather than direct importations from Asia.
Genomic patterns demonstrated multiple independent viral introductions followed by an extended window of undetected community spread.
