|dc.description.abstract||Prior to 1889 there had not been a serious
epidemic of influenza for over forty years; the result was that in that year the majority of medical
practitioners had no practical knowledge of the clinical aspects of the disease, and what was known as
influenza was really a feverish catarrh, or common
cold in the head.
Since the pandemic of 1889-90, the disease has practically always been present, occasionally breaking out. into epidemic form in the colder
months of the year; so that, in general practice,
many cases are met with, and one has every opportunity of studying the various aspects of the disease;
although it is no doubt true that many of the attacks
which are now in a loose way diagnosed as influenza,
are something else.
Influenza is, however, a disease in which
the symptoms are so varying, and the complications
so numerous and so grave, that a thorough understanding of the subject is very necessary.||en
