Knowledge, attitudes, and perceived barriers to tuberculosis care among patients and household contacts in Wolisso District, Oromia Region, Ethiopia.

BACKGROUND

Tuberculosis (TB) remains a major global health challenge, particularly in low-income settings where structural inequities hinder early diagnosis and care. Ethiopia, one of the 30 high TB-burden countries, continues to experience marked geographic disparities. Understanding knowledge, attitudes, and practices (KAP) among affected populations is essential to inform context-specific interventions supporting the End TB Strategy.

METHODS

A cross-sectional KAP survey was conducted in Woliso District (Oromia Region, Ethiopia) between April 2023 and December 2024, including 152 TB index cases and 326 household contacts. A structured, interviewer-administered questionnaire assessed knowledge of TB symptoms, transmission, diagnosis, and perceived barriers to care. Categorical variables were compared using Chi-square or Fisher's exact test, and continuous variables with Mann-Whitney test.

RESULTS

Among 478 participants (median age 28 years [IQR 19-40]; 44.1% female), 69.5% lived in rural areas. The main barriers to timely diagnosis were absence of nearby TB diagnostic facilities (13.4%), poor road conditions (6.3%), health system delays (5.9%), and financial constraints for transportation (3.8%). Poor roads and transport costs were reported more often by rural residents (p < 0.05), while absence of nearby TB diagnostic facilities was reported most often by index cases and older subjects (p < 0.05). Recognition of cough lasting >2 weeks (84.3%) and night sweats (65.7%) was common, while hemoptysis (49.6%) and fever (16.1%) were less recognized. Awareness of sputum and X-ray diagnostics was 87.2%, higher among index cases (95.4% vs. 83.4%, p = 0.0005). Although 77.0% considered TB life-threatening, 52.2% believed it was transmissible only through close or bed-sharing contact (p < 0.0001 for rural vs. urban). Older age correlated with better knowledge across most domains (all p < 0.01). Overall, subjects living in rural area had higher scores about barriers for accessing TB care (p = 0.0004) and attitude on TB (p = 0.01), and lower score about knowledge on TB (p = 0.002).

CONCLUSIONS

While TB knowledge and attitudes were generally high, misconceptions about transmission and persistent structural barriers hinder access to timely diagnosis and care. Expanding community-based diagnostic capacity, improving rural infrastructure, and integrating social protection strategies are key to advancing Ethiopia's progress toward End TB targets.
