EASES Existing morbidity and mortality statistics do not give usan accurate idea of the prevalence of these diseases in theUnited States, neither can some of the estimates published bycertain ardent champions of sex hygiene be considered asreliable. The army experience gives probably as accurate anidea as any. Thus according to Vedder, of the new recruitsreceived prior to the recent war, per cent, were undoubtedlysyphilitic; and 9 per cent, more, probably had syphilis. In thesecond million of the army raised by draft for the recent war,the incidence of venereal diseases, at the time when received,was per 1000 men. (See Fig. 3 a.) Among the sailorstreated by the Marine Hospital Service it is found that cent, of the annual cases are venereal. As a result of studiesupon this question, Banks estimates that 3 per cent, of males 44 PRACTICAL PREVENTIVE MEDICINE acquire venereal infection annually. The incidence is un-doubtedly higher in the American negro. Thus McNeil found. in Galveston that between 25 and 30 per cent, of all negroeswere syphilitic. The higher incidence of these infections in the DISEASES TRANSMITTED SOLELY BY CONTACT 45 Southern states as shown in Fig. 4, is due to the large propor-tion of negroes in the population. STANDARDS FOR THE DISCHARGE OF CARRIERS The Federal Public Health Service observes the followingprocedures before discharging venereal patients as non-infectious: A. Syphilis The absence of areas on the skin and mucosa from whichthe infective agent could be discharged. B. Gonorrhea 1. Males: (a) Freedom from discharge. (b) Clear urine without shreds. (c) Pus expressed from the urethra by prostaticmassage must be negative for gonococci on foursuccessive examinations at intervals of one week. (d) After dilation of the urethra by the passageof a full sized sound, the resulting inflammatorydiscbarge must be negative for gonococci. 2. Females: (a) No urethral or vaginal discharge.
