Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2)
As the name indicates, this coronavirus is related to the SARS beta coronavirus (SARS-1) that caused fatal outbreaks in 2002-2003. However, it is not the same virus, says the U.S. Centers for Disease Control and Prevention (CDC).
In molecular epidemiology, a study published on May 4, 2021, found the progenitor genome (proCoV2) is the mother of known SARS-CoV-2 coronaviruses. These researchers estimate that the SARS-CoV-2 progenitor was in circulation several weeks before the first genome sequenced in China, known as Wuhan-1, stated Sayaka Miura, a study's senior author.
On July 22, 2022, the ‘Special Report’ anchor presented on YouTube the timeline of how U.S. government officials responded to information about coronavirus origins.
The coronavirus that causes COVID-19 is mutating, which is expected as viruses mutate as they spread, stated the U.S. CDC. The original SARS-CoV-2 strain, detected in Wuhan, China, in December 2019, is the L virus strain. This human coronavirus (hCOV) has since mutated.
SARS-CoV-2 Diagnostic Tests
The COVID-19 tests most people discuss are RT-PCR, the nasal-swab test that detects viral RNA, and various antibody tests that see if you have an immune response due to past exposure to the SARS-CoV-2 virus. The first SARS-CoV-2 test kits under a EUA were distributed on February 7, 2020. For updated coronavirus test news, please visit 'Tests.'
