  Attempts to control the epidemic spread of COVID19 in the different countries
often involve imposing restrictions to the mobility of citizens. Recent
examples demonstrate that the effectiveness of these policies strongly depends
on the willingness of the population to adhere them. And this is a parameter
that it is difficult to measure and control. We demonstrate in this manuscript
a systematic way to check the mood of a society and a way to incorporate it
into dynamical models of epidemic propagation. We exemplify the process
considering the case of Spain although the results and methodology can be
directly extrapolated to other countries.
