ATLANTA (AP) - Health officials say better screening of
immigrants may explain the big dip in tuberculosis cases in the
U.S. last year.
The Centers for Disease Control and Prevention said this week
that the nation's TB rate dropped more than 11 percent last year.
That's the largest single-year decrease in more than 50 years of
record keeping. TB rates have been falling in the U.S. but
generally about 4 percent a year.
The drop was so steep that some experts are cautious about
celebrating. While better screening overseas may explain the
decline, the CDC says it could mean that some cases aren't being
diagnosed or treated.
