Evaluation of Tuberculosis Status in Family Members of Patients with Pulmonary Tuberculosis in Bam City in 2019

Screening for home contact with TB patients is essential to identify new infections. This study aimed to evaluate the tuberculosis status in family members of patients with pulmonary tuberculosis in Bam.

This cross-sectional study was conducted as a census of patients' family members whose records are registered during 2013-2019 in Bam Health Center. Patients' information was collected based on a checklist, and then sputum smear-positive patients were identified using tuberculin and sputum smear tests.

Ninety-seven of the patients had a positive sputum smear test result. Based on the records of these patients, 237 members of their families were examined as contact persons. Most of the patients were female and in the age group of 40-50 years; 76.8% of them had unprotected close contact, and 78.9% had a history of permanent contact with patients. Five (2.1%; 95% confidence intervals: 0.7-4.9) sputum-positive smear pulmonary tuberculosis cases were found in contacts of patients, most of them were over 50 years old and primarily women. 40% of these people had unprotected close contact, and 80% had a house with less than 70 square meters.

in this study, 2.0% of the family members of patients were sputum smear-positive. Identifying patients and following them up is essential to prevent the spread of tuberculosis in those people around them. Therefore, screening the patient's family members can significantly help ease the disease burden in Iran.
