During the year 1911, 522,722 cases of all kinds were treated in 17 dispensaries in New York City; 15,781, or 3.01 percent of these cases, were venereally affected. The hospitals of the city possess few beds for the reception of venereal patients; nevertheless, 5,380 persons--6.33 per cent of all cases treated in 13 different hospitals--were venereally affected, about two-thirds male, one-third female. These infections occur at any time from the first to the seventieth year,--the period of greatest frequency being between 16 and 30 years of age: between 16 and 20, 796 were males and 369 females; between 21 and 25, 1,182 and 454, respectively; between 26 and 30, 692 and 268. For several reasons these figures are far from suggesting the actual extent of venereal infection,--in the first place, because, as above stated, the hospitals receive but a fraction of the sufferers; in the second, because accurate diagnosis has only recently become feasible. The percentages increase heavily as soon as the more delicate and reliable tests devised by Wassermann and others are applied. For example, 308 adults were admitted to the medical wards of a certain New York hospital during the months of January, February, and March, 1913; though the Wassermann test for syphilis was made in the case of only 166 of these, 38, _i. e._, 23 percent of those examined, gave positive results; this is equivalent to 12.3 percent of the entire 308. Had the test been applied to all adults admitted, undoubtedly the ratio of syphilitic infection would have been higher still. As a matter of fact, the test as usually performed does not disclose all cases of infection; so that the prevalence of disease is actually greater than the tests indicate. The civil state of the patients in the cases first mentioned is shown in the following table: Males Females single married widowers single married widows 640 2950 57 589 802 90 From the standpoint of occupation, every social class is represented,--necessarily so, inasmuch as every social class figures in the phenomena of prostitution. The occupations given by male patients were as follows: professional, 52; clerical and official, 307; mercantile and trading, 250; public entertainment, 120; personal service, police and military, 186; laboring and servant, 1,181; manufacturing and mechanical industry, 932; agricultural, transportation, and other outdoor employments, 645; no occupations, 58; classified as unknown, 8; children, 11; congenital origin, 31; schoolboys, 10; students, 10. The occupations of female patients are as follows: professional, 46; domestic and personal, 1,144; trade and transportation, 109; manufacturing and mechanical, 86; no occupations, 72; unknown, 9; schoolgirls, 21; children, 76.
