The occurrence of certain epidemic episodes may in fact be encouraged by delays in the treatments or by not adequately fast clinical case management, which may be related to the backward bifurcation phenomenon as well as to an intriguing spiking dy...

Assessing the risk of measles resurgence in a highly vaccinated population: Belgium anno 2013.
