There are multiple definitions:

1. multiplicity of infection(English)

   • ratio of adsorbed, attached, or infecting agents to susceptible targets. Ratio varies as a function of numbers of infecting agents, how fast those agents attach, how much time is allowed for attachment, and how many targets there are to attach to. Overall, the ratios of infecting agents to targets can be described in terms of Poisson distributions
