In the latter, or southeastern portion, there are some large cities, but the bulk of the population may be called rural. A large proportion of the inhabitants in urban States have contracted measles in childhood, while in rural States a large percentage have not been exposed to the disease. Applying this information in discussing occurrence by camps, it is noted, for example, that Camp Pike, Ark., which stands at the head of the list, drew its quota of troops from Southeastern States, namely, Alabama, Arkansas, Louisana, Mississippi, and Tennessee. Camp Bowie, Tex., which stands second, drew its quota from Arkansas, Louisiana, and Texas. Camp Sevier, S. C., standing third, drew from Alabama, Kentucky, North Carolina, and South Carolina. Camp Wheeler, Ga., fourth on the list, drew its quota from Alabama, Florida, Georgia, Louisana, and Mississippi. On the other hand, Camp Grant, Ill., which drew its quota principally from Illinois, and Camp Dix, N. J., which drew principally from New York and New Jersey, stand at or near the bottom of the list of camps. The last three States are thickly settled and may be classified as urban States; while the other States mentioned, generally speaking, may be classified as rural. Next to Camp Pike, which had a high rate of occurrence for most of the epidemic diseases, comes Camp Travis, Tex. Camp Pike had 6,730 such admissions for measles among white, and 314 among colored, enlisted men. Camp Travis had 4,484 among whites and 337 among colored. Camp Pike also heads the list in the number of deaths, with a total of 211 men for the period of the war, 197 of which were among white troops. Camp Bowie, on the other hand, had the highest death rate for the period, as shown in Table 66. From the figures given above it is seen that measles was of far greater importance among white than among colored enlisted men. The comparative occurrence in the two races is illustrated in Chart XLIX, which shows admissions, deaths, case fatality, noneffectiveness, days lost, and discharges for disability among white and colored enlisted men serving in the United States. The admission and death ratios, as well as noneffective ratio and discharges for disability, were greater among white than colored enlisted men. The case fatality and average days lost per case were greater for colored than for white enlisted men. From the standpoint of epidemiology, the six months period commencing October 1, 1917, marks the measles period for the Army. During this time there were 51,022 primary admissions among white enlisted men, and 1,487 among colored, making a total of 52,509, or more than one-half of the total admissions for the entire Army serving in all countries. 56706-28- -27 MEASLES (ALL), BY NATIVE STATES RATIOS PER 1000 CHART XLVIII |
