[h=3]Europe reports declining TB rates, but MDR-TB at high levels[/h] The incidence of tuberculosis (TB) is declining in Europe, but the continent still sees 1,000 new cases a day and drug-resistant TB remains at high levels, the European Centre for Disease Prevention and Control (ECDC) and the World Health Organization's Regional Office for Europe (WHO Europe) said in a joint surveillance report today.
An estimated 360,000 Europeans developed TB in 2013, a drop of 6% compared with 2012, the agencies reported. But rates of multidrug-resistant TB (MDR-TB) remain at very high levels, particularly in the 18 high-priority nations, which see 85% of all new TB cases in the WHO's European Region. These countries accounted for most of the 38,000 TB-related deaths in 2013.
"MDR-TB is still ravaging the European Region, making it the most affected area of the entire world," said Zsuzsanna Jakab, PhD, WHO Regional Director for Europe, in a WHO Europe press release. "Only 50% of MDR-TB patients are found and half of them successfully cured. This calls for a considerable scaling up of access to safe, rational and efficient new TB drugs."
"At the current pace of an annual 6% decline, the [European Union/European Economic Area] will only be free of TB in the next century," said ECDC Director Marc Sprenger, MD, PhD. "In order to achieve elimination by 2050, for example, we would have to cut down cases at least twice as fast."

[h=3]CDC study says new screening has aided immigrant TB detection[/h] In related news, the US Centers for Disease Control and Prevention (CDC) today published a report in the Annals of Internal Medicine that said, because of screening guidelines issued in 2007, physicians overseas diagnosed 629 additional TB cases in immigrants in 2012 that otherwise might have been missed.
Before 2007, immigrants and refugees were screened for TB using a smear-based algorithm that could not diagnose smear-negative/culture-positive TB.
CDC researchers analyzed data from 1,650,961 immigrants who were screened by the smear-based algorithm and 1,561,460 who were screened by the newer culture-based algorithm. Although the annual number of TB cases detected from 2007 to 2012 decreased from 1,511 to 940, the annual number of smear-negative/culture-positive TB cases diagnosed increased from 4 to 629.
"The results of this study showed that the updated overseas screening guidelines led to a roughly one-third decrease in the number of TB cases among foreign-born persons within their first year in the United States," the CDC said in a news release yesterday.
