Introduction: Tuberculosis is a major health problem in developing countries including Sudan. Screening for TB cases through
Household contacts (HHCs) investigation is an appropriate strategy to interrupt transmission of TB.
Objectives: To determine the prevalence tuberculosis infection and risk factors for tuberculosis infection among household
contacts in Wadimadani locality, Central State, Sudan, between November 2015 and April 2016.
Methods: An analytical cross-sectional study conducted. During study period, To confirm TB diagnosis all suspects contacts
were tested through sputum samples, tuberculin skin test or chest x-ray. Structured questionnaire was used to collect socio-
demographic and environmental factors.
Results: One hundred forty six patients of smear-positive pulmonary tuberculosis were included in the study, 657 household
contacts were identified and screened. Forty three new TB cases were detected from household contacts, yielding a prevalence
of 6.5% (95% confidence interval= 0.05, 0.09) of latent tuberculosis infection (LTBI). Two factors were significantly associated
with LTBI among HHCs: duration of contact with a TB patient ≤ 4 months (P= 0.03) and the educational status (P= 0.02).
Conclusion: Screening of HHCs of index case of TB will contribute in early detection and treatment of new cases, and
considered as a forward step towards eliminating TB.
