The number of tuberculosis cases has dropped to a record low. But the disease continues to affect certain groups disproportionately.

A new study finds that TB cases occur more often in racial and ethnic minorities as well as people who are infected with HIV.

Infection rates were seven times higher for Hispanics, eight times for blacks and 25 timers higher for Asians than for whites.

TB is caused by germs spread through the air from person to person and it typically affects the lungs. Left untreated, it can be fatal.

The report appears in the Centers for Disease Control's Morbidity and Mortality Weekly Report.
