type of influenza.
The rise in mortality from pneumonia, this very similar type of
disease, in the spring of 1918 is so sudden, so marked and so general
throughout the United States as to point very clearly to a definite
relation. Everything indicates that the increased mortality from
pneumonia in March and April of 1918 was the consequence of a
beginning and largely unnoticed epidemic of influenza, the beginning
in this country of the pandemic which developed in the autumn of
that year.
In the British cities the epidemic manifested three distinct
waves—the first and slightest in point of mortality occurring in June
and July, the second and most severe in November, the third in
February and March. Data which need not be cited here in detail
indicate that the course of the epidemic in western Europe generally
was similar. In cities of India the sequence was similar but the
mortality far greater. In the United States the epidemic developed
more largely in a single wave during September, October and
November. If, however, the epidemic already mentioned as
occurring in the spring be considered the first phase and the explo
sive outbreak of the second, a third phase of recrudescence is quite
evident in many areas. In general, this winter recrudescence was
less marked in those cities which suffered most severely in the
autumn epidemic.
The prevalence of a serious epidemic of influenza was first
recognized in and around Boston in September of 1918. within
about two weeks it was general in the Atlantic seaboard, developing
a little later among cities further west. Rural districts were usually
attacked somewhat later than large cities in the same sections.
In the cities east of the line of the Appalachians the excess
mortality from pneumonia and influenza during the weeks ended
September 14, 1918, to March 1, 1919, was approximately 5.6 per
1,000 in cities between the Rocky Mountains and the Appalachians
4.35 and in those of Pacific Coast 5.55 per 1,000.
Notwithstanding this general geographic relation, there are not
ably wide differences in the same section, even between cities close
together, differences which are not as yet explained on the basis of
