Contagion is a passive item in The Binding of Isaac, added in the Afterbirth+ DLC.
The first enemy killed in each room will release a gas explosion that poisons nearby enemies.
Enemies poisoned by this explosion will also release gas upon death, spreading the effect.
Poisoned enemies don't have to die while poisoned in order for the gas explosion to take place.
The initial gas explosion deals 5 damage, and the poison deals Isaac's tear damage per tick for 6 total ticks.
