COMMON COLDS AS A POSSIBLE SOURCE OF CONTAGION FOR LOBAR PNEUMONIA.
In two instances of common colds, with no known contact with cases of pneumonia, Pneumococcus Type I was found to be the predominating organism, which strongly suggests that it was the etiological agent in these colds. If this is so, common colds of this type must be looked upon as a possible source of contagion in the development of lobar pneumonia due to the Type I pneumococcus.
