A new study supports the use of directly observed therapy to treat dangerous TB infections.
An examination of surveillance data for cases of multidrug-resistant tuberculosis (MDR-TB) reported to the CDC from 1993 to 2013 showed that DOT increased from 74% during 1993-2002 to 95% during 2002-2013, while all-cause mortality decreased from 31% to 11% during these periods, reported Jorge Salinas, MD, of the CDC division of tuberculosis elimination in Atlanta, and colleagues.
