It is evident that viral infection dramatically alters host gene expression, and these alterations have both pro- and anti-viral functions. While the effects of viral infection on transcription and translation have been comprehensively reviewed, less attention has been paid to the impact on alternative splicing of pre-messenger RNAs. Here we review salient examples of how viral infection leads to changes in alternative splicing and discuss how these changes impact infection.
