In Emilia-Romagna, Tommasino de' Bianchi recorded the recovery of Modena's first cases on 13 July 1510, writing that in the city "there appears an illness that lasts three days with a great fever, and headache and then they rise... but there remains a terrible cough that lasts maybe eight days, and then they recover."[1] This data would indicate that the first cases of flu, which has an incubation period of one to four days, began to fall ill in the Emilia-Romagna region around late June or early July. In Bologna an 8-year-old named Ugo Bancopagni, who would later become Pope Gregory XIII, became gravely ill with flu but recovered without permanent complications.[1]
