Tuberculosis prevalence among underfive children in household contact with negative acid fast bacilli adult pulmonary tuberculosis
Abstract
Background Risk of tuberculosis (TB) transmission is greatest if achild has household contact with positive acid fast bacilli (AFB)
adult pulmonary TB. Risk of TB transmission from negative AFB
adult pulmonary TB to underfive children is unknown.
Objective To find out the prevalence of TB infection and disease
among underfive children in household contacts with negative
AFB adult pulmonary TB.
Methods The study was performed at Balai Kesehatan Paru
Masyarakat (BKPM) Bandung on underfive children who live in
the same house with negative AFB adult pulmonary TB from
February to July 2006. History taking, physical examination,
anthropometric measurement, chest radiographs, and tuberculin
skin test were performed to all study subjects. Subjects were then
categorized as TB infection(positive tuberculin test only) or disease
(defined based on Pulmonology Workgroup of Indonesian
Paediatrics Council criteria, 2005).
Results Sixty one children (32 males and 29 females) had contact
with 54 negative AFB adults pulmonary TB. Tuberculosis infection
was found in six (10%), while disease was found in 10 (16%)
children. The prevalence of TB infection was 10% (95% CI
2.3;17.3) while prevalence of TB disease was 16% (95% CI
7.1;24.7).
Conclusion Tuberculosis infection and disease prevalence is
considerably high in household contact with negative EFB adult
pulmonary TB.
