A coronavirus related to SARS-CoV-2 has been isolated from Malayan pangolins illegally imported into Guangdong province. It is not the precursor of SARS-CoV-2, but comparison of viral genome sequences provides further evidence that the virus currently infecting humans was not produced in a laboratory. There are two important sequences in ...

The spike glycoprotein of the newly emerged SARS-CoV-2 contains a potential cleavage site for furin proteases. This observation has implications for the zoonotic origin of the virus and its epidemic spread in China. The membrane of coronaviruses harbors a trimeric transmembrane spike (S) glycoprotein (pictured) which is essential for entry ...

In this week's coverage of the coronavirus epidemic, the TWiV team discusses the fatality rate, China's initial reaction to the outbreak, conspiracy theories, how long the virus remains infectious on surfaces, and evidence for virus in the intestinal tract.

by Gertrud U. Rey Herpes simplex viruses establish lifelong persistent infection in sensory neurons of infected individuals, a phenomenon called latency. Latent viral genomes are "dormant" but can sporadically reactivate and begin replicating in a phase called lytic replication, which is often accompanied by shedding of virus particles and the ...

The TWiVerers continue their coverage of the new coronavirus outbreak in China, as the number of cases increase dramatically and the virus begins person-to-person transmission in other countries.
