# SARS-CoV-2 ## Identification SARS-CoV-2 is the coronavirus that causes [[COVID-19]]. It is not the disease itself and is distinct from SARS-CoV, the virus associated with the 2002–2004 outbreak of [[Severe acute respiratory syndrome|SARS]]. ## Contact-tracing relationship Contact tracing for COVID-19 seeks to identify people who may have been exposed to SARS-CoV-2 during a relevant infectious period. [[Google-Apple Exposure Notification]] estimated possible device proximity; it did not detect the virus, diagnose COVID-19, establish transmission, or prove that two identified people had interacted. ## Notebook relationship The exact term `SARS-CoV-2` is not visible in the current transcription of [[Scanned_20260730-1946]]. This note supplies the biological link required to keep the notebook's COVID-19, [[Epidemiology]], and [[Contact Tracing]] discussions technically precise. ## Governance boundary Disease-control categories should be based on validated epidemiological criteria. Extending encounter infrastructure to classify unrelated behavior, affiliations, or social “deviance” would be a different purpose and belongs under [[Social sorting]], not virology. ## Source - [WHO — Coronavirus disease (COVID-19)](https://www.who.int/news-room/fact-sheets/detail/coronavirus-disease-%28covid-19%29)
