Such a disease occurred through an “ill-fated visit” that eventually led to death; then it “lodged” in the host body in a “menacing fashion”; and, as in the case of all pestilential diseases, it may “evade defense measures”, thus successfully spreading among “the whole population” with the characteristics of “a real epidemic event”.
Se presentaba a través de una "funesta visita" significada con la muerte; se "instalaba amenazadora"; y como todas las enfermedades pestilenciales, podía "burlarse de las medidas para combatirla", para culminar su periplo en un paseo triunfante "por toda la población" con carácter de "una verdadera epidemia".
