Background
Latent tuberculosis infection (LTBI) remains an overlooked aspect of tuberculosis (TB) control in South Africa, despite its potential to develop into active disease. This study aimed to assess public awareness, perceptions of treatment, and perceived barriers to LTBI care in a high-burden rural setting.
Methods
A cross-sectional, community-based survey was conducted among adults in the King Sabatha Dalindyebo Local Municipality, Eastern Cape. A structured questionnaire assessed knowledge of LTBI, concerns about progression, perceived consequences, and treatment-related barriers. Data were analyzed using descriptive statistics, chi-square tests, and Pearson correlation, with results presented by demographic subgroup.
Results
Awareness of LTBI varied significantly by age, with the highest awareness among 20–29-year-olds (52.7%; 95% CI: 44.7–60.7; p = 0.5625) and the lowest in those aged 50– 59 (15.8%; 95% CI: 5.5–37.6; p = 0.0044). Belief in the necessity of treatment was strongest in the <20 group (66.7%) and those aged 20–29 (62.3%; 95% CI: 54.2–69.8; p = 0.0036), though actual treatment uptake remained low across all age groups, peaking at 14.8% (95% CI: 5.9–32.5; p = 0.0003) in the 30–39-year-old cohort.
Concern about LTBI progressing to active TB was widespread (75.1%; 95% CI: 69.3–80.1; p < 0.0001), but only 38.3% correctly identified the full consequences of untreated LTBI ( p = 0.0012). The most commonly cited barrier was lack of awareness (62.4%; 95% CI: 56.2–68.3; p < 0.0001). Correlation analysis revealed a weak but significant association between understanding of consequences and reduced informational barriers ( r = 0.186; 95% CI: 0.064–0.307; p = 0.0035), while emotional concern was not significantly associated with actual knowledge or behavior.
Conclusion
The findings highlight a disconnect between concern and action in LTBI care. While awareness and worry are common, they are insufficiently grounded in accurate knowledge or translated into treatment uptake. Community education, stigma reduction, and age-sensitive messaging are crucial for enhancing LTBI engagement and supporting TB prevention in rural South Africa.
