The name of the disease derives from the ship that it was carried on. It was set in motion after being carried on a rodent (like the bubonic plague) and between fleas (again like the bubonic plague) and the name Red Death is clearly an allusion to the Black Death (perhaps the most notorious case of flea/rat born plagues in history). The original disease is carried by fleas from one of the other worlds (likely the real world) Ciri traverses through in The Lady of the Lake. The Witcher 3 is set in 1272, which in the novels is one of the years of the great plagues.
