New Mexico health officials reported that the state saw its lowest number of TB cases since 2005, with only 40 newly diagnosed cases in 2012. However, state residents remain three times more likely to die from the infectious disease than any other Americans. Health officials reported that TB causes fatalities in approximately 15 percent of New Mexicans in active treatment for the disease each year, which was well above the national mortality rate of 4 percent. Authorities said the inflated death rate was caused by delayed treatment of some individuals because they were slow to seek medical care or were initially misdiagnosed. New Mexico reported six TB deaths last year.
