Long-term survivors in an epidemic without recovery

G. Schinaia
The analysis of epidemics without recovery often implies the inclusion of long-term survivors in the modeling process. Such individuals are characterized by a peculiarly long sojourn in a state of infection without any sign of progression towards the subsequent evolutionary state of the disease. A parametric modeling of their presence in an epidemic involves non-Markov staging of the infection process and of its development. In the present work, an approach involving survivor function is proposed,...
