Part Description
LP417540-4 SARS coronavirus 2
The 2019 Novel Coronavirus (2019-nCoV) is a coronavirus first identified as the cause of a respiratory illness outbreak in Wuhan, China. Initially, the outbreak was linked to a large seafood and animal market and thought to only be spread by animal to person contact. Within a short time, a growing number of patients who had not been exposed to animal markets were diagnosed with the infection, indicating person-to-person transmission. As of January 2020, infections with 2019-nCoV have been reported internationally, including Thailand and the United States, in due to confirmed cases in travelers from Wuhan. Overall, clinical symptoms appear milder than SARS Coronavirus (SARS-CoV) and Middle East Respiratory Syndrome (MERS) Coronavirus (MERS-CoV) infections as do the fatality rate and transmissibility.[PMID:31953166] Reported illnesses have ranged from minor or no respiratory symptoms to severe acute respiratory illness and death.
The full genome of the 2019-nCoV was first posted by Chinese health authorities in GenBank, the NIH genetic sequence database, and in the Global Initiative on Sharing All Influenza Data (GISAI) portal. This facilitated detection of the virus globally with subsequent sequences being nearly identical, suggesting a single, recent emergence from a virus related to bat coronaviruses and the SARS coronavirus. Real time Reverse Transcription-Polymerase Chain Reaction (rRT-PCR) tests have been developed by the Centers for Disease Control and Prevention (CDC) and others for the diagnosis of 2019-nCoV. The existing 2019-nCoV primer and probe sets are designed for the universal detection of SARS-like coronaviruses and for specific detection of 2019-nCoV.[CDC:coronavirus/2019-ncov]
