SummaryThe poster from the 2010 Holiday Lectures, Viral Outbreak: The Science of Emerging Disease, illustrating the size, geometry, and different classifications of viruses.
Viruses are genetically and structurally diverse. Each virus is specific about the host species, and even the cell it infects within the host. It is not known how many different viruses there are, but estimates run in the millions. This poster illustrates the wide variety of viral size, geometry, and genome type.
