<strong>SIRS</strong> Model<br />
MCs indexed by N with transition rates:<br />
ρ (s → i) = S · θI/N = Nθsi<br />
ρ (i → r) = ρI = Nρi<br />
ρ (r → s) = R = Nr<br />
Questions:<br />
• Establishment: Will the infection spread?<br />
• Spread: How does it develop with time?<br />
• Persistance: When does it disappear?<br />
