This will not spawn new virals, it will only attract ones that are already nearby and are in 'Shuffler mode'. Once an infected in the crowd is attacked, they will release a small cry that will trigger all virals nearby. One of the most dangerous new parts of their behaviour is the tendency of then to shuffle about in crowds of biters and appear fully normal. They often dodge attacks and hang back from the player charging in and backing off.ДЄs of the Enhanced Edition Update, they also posses new behaviors that allow them to get the jump on players and further enhancing their combat abilities.

Virals possess advanced mental faculties when compared to their Biter counterparts. Unlike the slower, lumbering types of infected (that all virals will eventually reach as their bodies degrade), Virals do not bite, nor could they 'lunge' at a player and trap them into a QTE instead, they use their hands to viciously claw and punch their victims. They can also jump and climb over obstacles and buildings, allowing them to chase after the player even when he's in a spot where most normal infected can't reach. They run far faster than any other Infected, except for the Volatile and Night Walker. As a result, their bodies still retain the physical strength needed for them to possess a high level of fitness and agility. However, they are still physically alive as they are seen speaking multiple times.

Virals are humans that have only very recently succumbed to the infection.
