Risk factors for transmission of Mycobacterium tuberculosis in a primary school outbreak : lack of racial difference in susceptibility to infection. Commentary. Authors' reply.
Recent data have suggested that there are racial differences in the susceptibility to infection by Mycobacterium tuberculosis.
An opportunity to test this suggestion was afforded by an outbreak of tuberculosis in a racially mixed elementary school in St.
Louis County, Missouri.
A physical education teacher was discovered to have cavitary pulmonary tuberculosis.
Of 343 students in the school, 176 (51 percent) were found to be tuberculin skin test positive (>=5 mm induration by Mantoux method); 32 children had abnormal chest radiographs.
More frequent contact with the physical education teacher was associated with infection (p<0.001).
