To estimate the prevalence of rifampicin-resistant tuberculosis (RR-TB) among adults in Nangarhar Province, identify independent risk factors through a case-control analysis, and describe phenotypic resistance patterns among RR-TB cases, highlighting the significance of these findings in the context of Afghanistan's TB burden.
Key Findings:
RR-TB prevalence and associated risk factors were identified, with a focus on household and exposure-related factors, including specific prevalence rates.
Interpretation:
The findings underscore the need for targeted interventions to address the specific risk factors for RR-TB in Nangarhar, particularly in densely populated households, and suggest potential strategies.
Limitations:
Limited generalizability due to the study's focus on a single province, which may affect the applicability of findings to other regions; potential biases in self-reported data and the absence of formal psychometric validation for the questionnaire should be noted.
Conclusion:
The study provides critical local evidence to inform interventions aimed at controlling RR-TB transmission and improving treatment outcomes in Nangarhar Province, emphasizing the urgency of addressing this public health challenge.
