Tuberculosis
Mycobacterium tuberculosis is as old as man's record history. Although several types of Mycobacteria can cause natural tubercular disease in humans and animals, Nycobacterium tuberculosis has evolved to be primarily a human pathogen in nature. National surveillance of TB morbidity has consistently demonstrated that the burden of TB in the United States falls disproportionately on members of racial and ethnic minorities. TB rates among Hispanics, non-Hispanics blacks, and those of Asian or Pacific Island descent are significantly higher than non-Hispanic whites. MORE DETAIL

Predicting Active Pulmonary Tuberculosis
Predictive models to assess the likelihood of pulmonary tuberculosis are available. The models are based on information related to clinical and radiographic data. The models are of two types. Model A is simple and quick algorithm that would allow health care providers to determine whether isolation is needed for suspicion of active pulmonary tuberculosis. Model B is based on a complex statistical analysis and provides information about the likelihood of having pulmonary tuberculosis.
