TB incidence rate drops 6.1 percent in 2012
The CDC published the number of 2012 TB cases in its Morbidity and Mortality Weekly Report in light of World TB Day 2013 on Sunday. There were 3.2 cases of newly-diagnosed TB per 100,000 people in the U.S. in 2012, the Yahoo! Contributor Network reports.
There were close to 10,000 cases reported in the U.S. last year. Forty percent of the 3,143 counties in the country did not report a single new case of the disease in the last three reporting years. Four states, Texas, New York, Florida and California, combined to report 49.9 percent of the total new cases, 4,967 cases in all.
West Virginia reported the lowest TB incidence rate at 0.4 for each 100,000 people, while Alaska reported the highest with nine out of every 100,000. The medicine incidence rate for the states was 2.3 cases per 100,000 people, according to the Yahoo! Contributor Network.
U.S. TB incidence rates grew in the late 1980s, in part, because of the AIDS epidemic, which left many susceptible to TB. Since that time, the CDC and local health departments increased their resources for TB. Cases dropped by close to 40 percent since 2000, NPR reports.
