Tuberculosis Declines In US, But Not For All Groups: Study


Even though the overall tuberculosis (TB) rates have declined in the United States, but new data says it is not the same for all groups.

Negar Niki Alami, MD, from the Epidemic Intelligence Service, CDC, Atlanta, Georgia, said in 2013 the foreign-born persons had a 13 times greater TB incidence compared to the people born in the US. They accounted for 64.6 percent cases.
Alami and colleagues reported in 2013 that US saw 4.2 percent decline in the TB incidences compared to 2012.

The report was published in the March 21 issue of Morbidity and Mortality Weekly Report. It adds more than fifty percent of the non-US born people originated from 5 countries – Mexico, China, India, Philippines and Vietnam.

The report further added that among the foreign-born individuals with TB cases the Asians accounted for 95 percent incidences, Hispanics 75 percent, Blacks 40 percent and whites born outside US 23 percent.

Homeless people were infected 10 times more than the overall national TB incidence, says the report.

Also, despite having only one-third of the US population, the TB cases accounted for more than 50 percent in California, Florida, New York and Texas together.

The authors write focused TB control efforts is required in the US among the mass populations and also in the geographic areas with disproportionate burdens of the disease.

The study was led by Suzanne M. Marks, MPH, from CDC’s Division of Tuberculosis Elimination, Atlanta.
