TL;DR: Identification and characterization of a new coronavirus (2019-nCoV), which caused an epidemic of acute respiratory syndrome in humans in Wuhan, China, and it is shown that this virus belongs to the species of SARSr-CoV, indicates that the virus is related to a bat coronav virus.

TL;DR: The basic virology of SARS-CoV-2 is described, including genomic characteristics and receptor use, highlighting its key difference from previously known coronaviruses.

TL;DR: Investigation on patients in a local hospital who were infected with a novel coronavirus found the presence of 2019-nCoV in anal swabs and blood, and more anal swab positives than oral swabs positives in a later stage of infection, suggesting shedding and thereby transmitted through oral–fecal route.

TL;DR: These results provide the strongest evidence to date that Chinese horseshoe bats are natural reservoirs of SARS-CoV, and that intermediate hosts may not be necessary for direct human infection by some bat SL-CoVs, and highlight the importance of pathogen-discovery programs targeting high-risk wildlife groups in emerging disease hotspots.

TL;DR: It is hypothesized that the direct progenitor of SARS-CoV may have originated after sequential recombination events between the precursors of these SARSr-CoVs, and highlights the necessity of preparedness for future emergence of Sars-like diseases.
