Testing for SARS-CoV-2 Infection Test Types. Viral tests, including nucleic acid amplification tests (NAATs, such as PCR tests), antigen tests and other tests (such as breath tests) are used as diagnostic tests to detect current infection with SARS-CoV-2, determine the need for prevention measures like isolation, and inform an individual’s medical care.

Dec 31, 2020 · SARS-CoV-2, the virus that causes COVID-19, has had a major impact on human health globally; infecting a large number of people; causing severe disease and associated long-term health sequelae; resulting in death and excess mortality, especially among older and vulnerable populations; interrupting routine healthcare services; disruptions to travel, trade, education and many other societal ...
Oct 23, 2020 · SARS-CoV-2 is an enveloped β-coronavirus, with a genetic sequence very similar to SARS-CoV-1 (80%) and bat coronavirus RaTG13 (96.2%). 2 The viral envelope is coated by spike (S) glycoprotein, envelope (E), and membrane (M) proteins ( fig 1 ). Host cell binding and entry are mediated by the S protein. The first step in infection is virus ...
Feb 11, 2020 · ICTV announced “severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)” as the name of the new virus on 11 February 2020. This name was chosen because the virus is genetically related to the coronavirus responsible for the SARS outbreak of 2003. While related, the two viruses are different.
Dec 20, 2023 · Diagnostic Testing for SARS-CoV-2 Infection. For diagnosing current SARS-CoV-2 infection, the Centers for Disease Control and Prevention (CDC) recommends using either a nucleic acid amplification test (NAAT) or an antigen test. 1 Testing may also be used for screening and to determine the length of a patient’s isolation period. 2 There may be a window period of up to 5 days after exposure ...
The SARS-CoV-2 genome is a strand of RNA that is about 29,900 bases long--near the limit for RNA viruses. Influenza has about 13,500 bases, and the rhinoviruses that cause common colds have about ...
