Mitigating the outbreak of an infectious disease over its life cycle: A diffusion-based approach.

We first qualitatively divide the cycle of an infectious disease outbreak into five distinct stages by following the adoption categorization from the diffusion theory. Next, we apply a standard mechanistic model, the susceptible-infected-recovered model, to simulate a variety of transmission scenarios and to quantify the benefits of various countermeasures. In particular, we apply the specific values of the newly infected to quantitatively divide an outbreak cycle into stages.

Objective: To investigate the effectiveness of reverse island flaps of digital artery parallel for repairing degloved injuries of the fingertip.

Methods: Between June 2008 and January 2010, 13 cases of degloved injuries of the fingertip were treated. There were 8 males and 5 females with an average age of 34 years (range, 19-62 years).
