Current Opinion in Virology 

TL;DR: Some of the most potent antiviral effectors reinforce the system by further inducing IFN or ISGs, suggesting that some viruses may have evolved to co-opt IFN effectors for a survival advantage.

TL;DR: The potential of metagenomics for characterization of the normal viral population in a healthy community and identification of viruses that could pose a threat to humans through zoonosis is discussed and a new model of the Koch's postulates named the ‘Metagenomic Koch's Postulates’ is proposed.

TL;DR: An overview of the available data from experimental and observational studies on the transmission routes of respiratory viruses between humans is presented, knowledge gaps are identified, and how the available knowledge is currently implemented in isolation guidelines in health care settings is discussed.

TL;DR: The current state of bacteriophage genomics shows that the genetic diversity of the population is very high, that phages have been actively evolving for billions of years with active engagement of horizontal genetic exchange, and that their genomes are consequently pervasively mosaic in their architectures.

TL;DR: Gene transcription signatures unique to SARS-CoV disease states have been identified, but host factors that regulate exacerbated disease phenotypes still remain largely undetermined.
