مستخلص: COVID-19, caused by the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), remains an ongoing global health challenge. This study analyzed 3641 SARS-CoV-2 positive samples from the El Paso, Texas, community and hospitalized patients over 48 weeks from Fall 2021 to Summer 2022. The binational community along the U.S. southern border was predominantly SARS-CoV-2 Delta variant (B.1.617.2) positive for a 5-week period from September 2021 to January 2022 and quickly transitioned to the Omicron variant (B.1.1.529), which was first detected at the end of December 2021. Omicron replaced Delta as the predominant detectable variant in the community and was associated with a sharp increase in COVID-19 positivity rate, related hospitalizations, and newly reported cases. In this study, Omicron BA.1, BA.4, and BA.5 variants were overwhelmingly associated with S-gene dropout by qRT-PCR analysis unlike the Delta and Omicron BA.2 variants. The study reveals that a dominant variant, like Delta, can be rapidly replaced by a more transmissible variant, like Omicron, within a dynamic metropolitan border city, necessitating enhanced monitoring, readiness, and response from public health officials and healthcare workers.
