Contagious Explosives are biological weapons, functioning similarly to Chemical Explosives.
On detonation, the explosives don't do any block damage, but instead release an invisible gas that contaminates any mobs within the radius, causing 4 effects:
Unlike the chemical explosive the effects of this bomb do not stop unless you take a antidote. Virus is a special effect that acts just like poison but with less damage. However, virus will spread to other mobs at close range, gaining the same effects. While the Hazmat Suit will not protect you, Antidotes will instantly cure yourself. If a pig or villager contracts the disease, they are instantly turned into a Zombie or a Zombie Pigman respectively. Neither take damage from the disease, but can carry it. The disease will travel through all walls so a bunker will not protect you.
