School and household tuberculosis contact investigations in Swaziland: Active TB case finding in a high HIV/TB burden setting.

ABSTRACT:

Background

Investigation of household contacts exposed to infectious tuberculosis (TB) is widely recommended by international guidelines to identify secondary cases of TB and limit spread. There is little data to guide the use of contact investigations outside of the household, despite strong evidence that most TB infections occur outside of the home in TB high burden settings. In older adolescents, the majority of infections are estimated to occur in school. Therefore, as part of a project to increase active case finding in Swaziland, we performed school contact investigations following the identification of a student with infectious TB.

Methods

The Butimba Project identified 7 adolescent TB index cases (age 10-20) with microbiologically confirmed disease attending 6 differ
