From: Targeted Recovery as an Effective Strategy against Epidemic Spreading

Time evolution and radius of the confined region. The number of infected nodes as a function of time for \(r=10\), \(\varepsilon =1\) and two different initial circular spreading seeds. In the stationary state, the epidemic is still confined to a deformed circular spot. The inset shows the spreading radius \(R=\sqrt{{n}_{st}(r)N/\pi }\) of the confined region as a function of the spreading rate \(r\). All simulations have been performed on square lattices with \(N\) nodes and a circular spreading seed.
