The committee's findings were subsequently summarized as follows: After discussing the available evidence as to the bacteriology of the present epidemic, the majority of those present were agreed that there was considerable doubt as to the primary etiological significance of the Bacillus influenzae of Pfeiffer, and considered that the existence of some as yet undiscovered virus must be regarded as possible.
