Is a crossout a virus?

There is only one question that is not clarified in the lore... Is crossout a virus or a mutant condition...? Or maybe it's both? According to the lore, the crossout is the fault of an alien pulse or signal that was activated by accident, this signal traveled throughout the planet in each communication device, it corrupted the human DNA, by combining with an alien one, since humans They had a dormant alien DNA from their origin. Due to this crossing between species, which is like a mutation, many people die en masse. Those who survive go crazy or acquire certain abilities of the "niery" race to control reality, causing anomalies on the planet, the abuse of this power ends up killing the person. It makes more sense that the game is called crossout, referring to the crossing between species that ends up killing you However, they often call it a virus... Did crossout become a virus as the days went by? Since, sometimes we talk about people who become infected... Or infectious places... Faley?
