Repulsion of superinfecting virions: a mechanism for rapid virus spread. Science 2010, 327, 873-876. Often the simplest observation inspires the most profound insight. Such is the case with a recent paper from Doceul et al. in the February 12 issue of Science [1]. The simple observation is that vaccinia virus plaques grow faster than can be accounted for by the replication cycle of the virus. The insight, after a good deal of novel experimentation, is that virus is surfing on a wave of infectivity at the leading edge of a growing plaque, turfed from cells that are infected but not yet producing virus in order to access virgin cells. The observations represent a fresh perspective on the fundamentals of virus replication and at the same time offer opportunities for advances in antiviral therapy. Vaccinia virus, the prototypical poxvirus, is the virus that was used as a live vaccine
