To assess the impact of treatment accessibility on HIV-TB co-infection, emphasizing its significance in improving health outcomes, using fractional-order modeling.
Approach:
Key Findings:
HIV-positive individuals are significantly more likely to develop active TB compared to HIV-negative individuals, underscoring the need for targeted interventions.
The fractional-order model provided improved fit and insights into transient dynamics compared to integer-order models, suggesting its potential for better treatment planning.
Integrated approaches combining HIV and TB interventions are essential for effective management, particularly in enhancing treatment accessibility.
Interpretation:
The findings underscore the complexity of managing HIV-TB co-infection and highlight the urgent need for integrated treatment strategies that consider the unique dynamics of both diseases to improve treatment accessibility.
Limitations:
Reliance on aggregated national data may obscure regional variations; future studies should consider disaggregated data.
The model did not explicitly account for variations in ART coverage over time, which could be addressed in subsequent research.
Parameter values calibrated for specific regions may limit transferability of findings; further validation in diverse settings is recommended.
Conclusion:
Addressing the dual burden of HIV and TB requires innovative modeling approaches and integrated healthcare strategies to enhance treatment accessibility and effectiveness, particularly in resource-limited settings.
