Pima County has resumed tuberculosis skin testing.
The screenings re-started last week after a national shortage of the Tubersol solution for skin testing was resolved, Pima County Health Department officials said.
Tuberculosis skin tests are conducted at the county's tuberculosis clinic, 2980 E. Ajo Way.
The clinic is open 7:30 a.m. to noon Mondays, Wednesdays and Fridays and from noon to 4 p.m. Tuesdays. It is closed on Thursdays. Skin tests are $15 and available on a walk-in basis during clinic hours.
The Health Department typically does about 425 routine screenings per month.
TB is caused by a bacterium called Mycobacterium tuberculosis, which usually attacks the lungs, but TB bacteria can attack any part of the body. If not properly treated, TB can be fatal.
It is spread through the air from one person to another, the U.S. Centers for Disease Control and Prevention says. The TB bacteria are put into the air when a person with active tuberculosis of the lungs or throat coughs, sneezes, speaks or sings. People nearby may breathe in these bacteria and become infected.
There were 28 cases of TB reported in Pima County in 2011, and 10,528 nationwide. Yuma, Pinal and Apache counties have the highest rates of TB in Arizona.
