I have always been keen on the story of my fellow countryman "colleague": the protomedico Giovanni Filippo Ingrassia who faced the plague epidemic (1575-76) of Palermo containing its effects: three thousand deaths. Very little compared to eighteen thousand in Milan and thirty thousand in Genoa. Years before, he had already proved himself identifying in the swamp lands, fed by the river Papireto, which surrounded the city of Palermo the cause of malaria. Obviously, without knowing anything - given the time - of Plasmodium malariae and how this was transmitted by mosquitoes. But reflecting on how this infection spread among the population. Unfortunately for him he did not see the results of his intuitions: only in 1591 (11 years after his death) the praetor Salazar had the river Papireto channelled determining the disappearance of malaria from Palermo.
