title: Barcoding influenza virus to decode transmission.
abstract: How much population diversity is transmitted during influenza virus infection? In this issue of Cell Host & Microbe, Varble et al. (2014) report a method of tagging influenza viruses with a unique genetic "barcode" that allows them to be traced through transmission and growth chains, providing a leap forward for the field.
