A new study has assessed TB infection and active TB disease during children's first decade of life in high-burden settings. The new results found that there was a consistently high rate of annual TB infection among children in the study group -- between 4-9 percent -- and that more than 10 percent of children developed TB disease by the time they were 10 years old. The study builds upon a previous analysis by some of the researchers which also found high rates of TB infection and disease in children up to five years old.
