AVOIDING COLDS
Infection
Bacteria play a part in most colds. In some cases there is a general infection, with local symptoms, as in grippe; in others there is a local infection, with mixed classes of bacteria. It is probable that these various forms of bacteria are constantly present in the nasal secretions, but do not cause trouble until the local resistance or the general resistance is in some way lowered.
