ANALYSIS OF SIX ANNUAL SEASONS OF FALL HAY FEVER IN NEW ORLEANS, LA.

By WM. SCHEPPEGRELL, A. M., M. D., President, American Hay-fever Prevention Association,
Surgeon in Charge Hay-fever and Asthma Clinic, Charity Hospital.

A careful study of the fall hay-fever seasons from 1916 to 1922, inclusive, based on clinical, pollenometric, and meteorologic data, gives interesting information on the character and course of hay fever. The fall hay fever has been selected for this analysis, as the principal cause of this form of the disease in Louisiana, in which State these records were taken, is the common ragweed pollen, the buoyancy of which, on account of its small size (20 microns) and spiculated surface, is so great that its number is fairly uniform within the radius of its potential area. By allowing for the difference in its season of bloom, and for weather conditions, the results may be considered representative of the States east of Kansas generally. By substituting the wormwood (Artemesia) for the ragweeds, the statement applies for the Pacific and Rocky Mountain States.1

The spring and summer hay fever is due to numerous other pollens, generated by grasses, plants, and trees, individually less common than the ragweeds and most of the pollens of which are also less buoyant than the pollen of these weeds. On this account, an analysis of the spring and summer hay fever is omitted in this report, as being more of local than of general interest.

Complete records are kept at our laboratories of the clinical reports and of the pollen and weather reports, tables of the latter for the months of September and October, 1916 and 1918, and of August, September, and October, 1922, being shown on the following pages. In addition to the individual records, which are made at the Hay-fever and Asthma Clinic, a condensed clinical record is kept showing the dates of acute attacks of the patients, with a view of checking these against variations of the pollenometric reports and weather conditions.
