Impact of fully implemented household contact management in children younger than 15 years as incremental demands on the health-care system required to avert one tuberculosis case or death
(A) Scenario B versus scenario A. (B) Scenario C versus scenario A. Error bars show 75% uncertainty interval. Scenario A=no household contact management. Scenario B=preventive therapy to children younger than 5 years and children who are HIV positive. Scenario C=preventive therapy to children younger than 5 years and children who are HIV positive or TST positive.
