Tuberculosis is now the leading cause of death from infectious diseases for children of all ages globally

Children with vulnerable immune systems, such as the very young, HIV-infected or severely malnourished, are most at risk for falling ill or dying from tuberculosis. Children with tuberculosis are often poor and living in vulnerable communities that lack access to health care. Adolescents are at particular risk of developing adult type disease, i.e., often sputum smear-positive and highly infectious.
