Influenza: the agent.
Less perplexing than its epidemic behavior is the nature of the influenza virion as such, which is now one of the best understood viruses in terms of morphology and replication. Among the aspects of the virus discussed in this article are the composition of its genome, the components of its envelope, and the probable molecular structure of its two surface proteins as well as their relative roles in antigenicity.
