  The emergence due to the outbreak of the COVID-19 disease, caused by the
SARS-CoV-2 virus, suddenly erupted at the beginning of 2020 in China and soon
spread worldwide. This has caused an outstanding increase on research about the
virus itself and, more in general, epidemics in many scientific fields. In this
work we focus on the dynamics of the epidemic spreading and how it can be
affected by the individual variability in compliance with social norms, i.e.,
in the adoption of health and hygienic social norms by population's members.
