Cackle Fever

This disease targets humanoids, although gnomes are strangely immune. While in the grips of this disease victims frequently succumb to fits of mad laughter, giving the disease its name.
Symptoms manifest 1 hour after infection and include fever and disorientation. The infected creature gains one level of exhaustion that can't be removed until the disease is cured. Any event that causes the creature great stress including entering combat, taking damage, experiencing fear, or having a nightmare the creature takes psychic damage and becomes incapacitated with mad laughter for 1 minute.
