Flu spread over the Alps into Switzerland and the Holy Roman Empire. In Switzerland it is documented as being called das Gruppie by the Mellingen chronicler Anton Tegenfeld,[25] the flu nickname then preferred by German-speaking Europeans. A respiratory illness seemed to have menaced the Canton of Aargua in June, with the population falling ill with sniffling, coughing, and fatigue.[26] German physician Achilles Gasser recorded a deadly epidemic spreading over the Holy Roman Empire's upper kingdoms, branching into the cities and the "whole mankind:" Mira qua edam Epidemia mortales per urbes hanc totamque adeo superiorem Germaniam corripiebat, qua aegri IV vel V ad summum dies molestissimis destillationibus laborabant ac ration privati instar phrenicorum furebant, atque inde iterum convalescebant, paucissimis ad Gorcum demissis.[3]
