Abstract

PURPOSE: The household contacts of a known case of sputum positive tuberculosis forms a high risk group, to which selective case finding can be targated.

METHODS: One hundred cases of sputum positive pulmonary tuberculosis were selected as “Index cases” and their household contacts as the study group. 394 contacts participated in the study . After history taking and complete physical examination they were subjected to investigations. Prevalence of infection was calculated by conducting “Tuberculin test” (Montoux test) with 5 TU-RT23 with tween 80. Sputum examination by Z N staining (Gastric Lavage, where required) was done for detecting AFB (Tubercular bacilli).

RESULTS: Prevalence of infection among contacts was 51.27% (which is 40% in general population). Prevalence of disease including all cases was 3.8% (2% in general population) and prevalence of sputum positive cases among contacts was 1.77% as compared to 0.4% in general population.

CONCLUSION: Prevalence of infection and disease is definitely high among household contacts of sputum positive cases.

CLINICAL IMPLICATIONS: Initial examination of household contacts of sputum positive cases was essential.
