| description | Background and Objectives: At present, investigation of extensive contact of tuberculosis (TB) patients’ families is not a routine part of TB control efforts in most countries. This study was conducted to evaluate the effective contacts of TB cases to assess the potential risk of transmission and its determinants in their families.
Methods: In this cross-sectional study, registered TB cases in Kerman, Iran provided information about their family size and type and frequency of unprotected effective contacts with their families from 2014 to 2015. The unprotected effective contact was defined using the Centre for Disease Control (CDC) classification (2005) based on the close, frequent, and long-term contact of TB cases. The demographic variables and the frequency of effective contact were analyzed using a logistic regression model with Stata version 12 with 95% confidence intervals.
Results: Overall, among 407 contacts of 74 TB cases, 73% had effective contacts. Having an effective contact was significantly higher among females (Adjusted Odds Ratio (AOR)=5.1; 95% CI:1.9-13.7); those with a lower education level (AOR=4.0; 95% CI: 1.4-15.1), lower income (AOR=7.7; 95% CI: 2.2-27.0), and a house size ≤80 m2 (AOR=16.6; 95% CI: 5.1-54.3); Afghan patients (AOR=30.2; 95% CI: 3.4-272.1); and those living in the rural areas (AOR=4.9; 95% CI: 1.8-21.9).
Conclusion: It seems that unprotected effective contact with the family members is high among TB patients, which can be a serious concern for the control of TB in this area. Reducing these unprotected effective contacts through educating patients and their families besides screening of the family members can help the health sector to decrease the burden of TB in Iran. |
