A model for obtaining predictable natural transmission of rhinoviruses in human volunteers.

A model has been developed in which rhinoviral colds can be predictably transmitted by experimentally infected donors to susceptible recipients in a continuously monitored and controlled environment under simulated natural conditions. Rates of transmission correlated closely (r = .926, P less than .01) with donor-hours of exposure. This model can be used to define routes of transmission, to explore methods of controlling dissemination, to study resistance mechanisms, and to test preventive and therapeutic agents.
