I'm not sure if this "saint" has historically been considered the patron saint of pandemics, that may be misinformation or regular Xian rewriting of history. But anyway, some Xians are now literally praying to this so-called saint, who in their stories is supposedly linked to Northern Italy:

My apologies for the Xian garbage on this site, it's the site that had the info though.
