Abstrak
<p>In this paper it is considered about Amanded Basic Virus Infection Model (ABVIM), with defined R<sub>0</sub> which is free from carrying capacity. R<sub>0</sub> makes ABVIM reasonable for interpreting Hepatitis B virus infection. The behaviour of stability of ABVIM in free virus equilibrium point with R<sub>0</sub> less than one and endemic equilibrium point more than one is given with numerical simulation.</p><p>Key words: Basic virus infection model, Hepatitis B virus infection, equilibrium point, stability</p>
