At least half a million children become ill with tuberculosis and up to 70,000 children die of it every year. The World Health Organization has estimated that around 10 percent of the global TB caseload occurs in children 0-14 years of age. However, there are reports that children account for up to 40 percent of all cases being treated for TB. Children are also susceptible to the dual epidemic of TB-HIV. Most children will catch tuberculosis from a family member and if they are living with HIV they are even more in danger of developing more severe forms of tuberculosis with higher mortality rates.
