RT Journal A1 JENKINS J T1 A few points on prophylaxis of tuberculosis JF Journal of the American Medical Association JO Journal of the American Medical Association YR 1909 FD September 11 VO LIII IS 11 SP 865 OP 866 DO 10.1001/jama.1909.92550110035002c UL http://dx.doi.org/10.1001/jama.1909.92550110035002c AB It is important to prevent future generations from contracting tuberculosis by a thorough course of preventive medicine and hygiene taught in our public schools. Germs are everywhere, and it is essential not to disseminate the pathogenic varieties. Expectoration in the open air should not be tolerated.We must treat properly the cases already under our observation. Individuals suffering with tuberculosis should be cautioned against marrying. If the married state hastens the progress of the disease, it is natural to believe that the offspring from a union of tuberculous individuals would also have a tuberculous tendency, very much as the children of inebriates have a tendency toward inebriety. The consensus of professional opinion, however, says that tuberculosis is not hereditary.It seems reasonable that the system may be fortified to resist disease by conservative measures, such as the following:1. Regular, temperate and cleanly habits.2. Abundant sunshine and fresh air.
