Summary
Hepatitis B virus (HBV) transmission can be effectively controlled through spontaneous clearance, full immunity recovery in chronic individuals, and reducing risk factors. These interventions significantly regulate and limit HBV spread, offering a viable control strategy.
Area of Science:
- Epidemiology
- Mathematical Biology
- Virology
Background:
- Hepatitis B virus (HBV) poses a significant global health challenge.
- Understanding transmission dynamics is crucial for effective control strategies.
Purpose of the Study:
- To analyze the impact of spontaneous clearance, recovery with immunity, and risk factor reduction on HBV transmission dynamics.
- To establish the mathematical model's solution existence and positivity.
- To determine the model's threshold quantity and analyze parameter sensitivity.
Main Methods:
- Mathematical modeling of HBV transmission.
- Analysis of model equilibrium existence, positivity, and global stability using Lyapunov and comparison theorems.
- Sensitivity analysis to identify key parameters influencing HBV spread.
- Computational simulations for validation.
Main Results:
- The study established the existence and positivity of the HBV model solutions.
- Sensitivity analysis revealed critical parameters affecting HBV transmission.
- Global stability analysis confirmed the long-term behavior of the model.
- Computational simulations validated the analytical findings.
Conclusions:
- Spontaneous clearance, recovery with full immunity, and risk factor reduction are effective in controlling HBV transmission.
- These factors play a vital role in regulating and mitigating the spread of Hepatitis B virus.
- The findings provide a strong basis for implementing targeted interventions against HBV.
