Universal COVID-19 testing in West Virginia nursing homes used to slow infection spread

A field report describes the operational use of universal COVID-19 testing for both residents and staff members in nursing homes across West Virginia. The setting involves a high-risk congregate living environment. No specific sample size, comparator group, or follow-up duration is reported.

The main reported outcome was the use of this testing strategy to slow the spread of SARS-CoV-2 infections and to prevent large outbreaks within these facilities. No quantitative results, effect sizes, absolute numbers, or statistical measures (such as p-values or confidence intervals) are provided. The report is purely descriptive of an implemented practice.

No information on safety, adverse events, or tolerability is included. Key limitations stem from the report's nature: it is not a formal study. There is no control group, no measurement of comparative effectiveness, and no statistical analysis to quantify any benefit. The practice relevance is limited to a descriptive account of one region's operational response in a specific high-risk setting during the pandemic.
