Is new immigrant screening for tuberculosis still worthwhile?
between 1990-1994 the official POA system continued to perform poorly. The yield of new tuberculosis cases detected was lower than in the 1980s. Chemoprophylaxis at 4% and BCG vaccination at 31% showed that preventive health measures were appropriate for over one-third of new immigrants aged under 30.
Previous early and repeated exposure to antibiotics may predispose individuals to develop JIA. Alternatively, the apparent association may reflect shared susceptibility to infections and JIA.
