Doctors in Cleveland became extremely concerned when they had an increase of infants brought to the emergency room with bleeding of the lungs. Doctors quickly called on the Centers for Disease Control and had them investigate the matter. The CDC found that all babies were from the same area and all of their houses had suffered from water damage. After further investigation and research a black fungus was determined the killer of three infants. The fungus develops in moist conditions, becomes airborne and threatens developing organs, much like the fast growing lungs of babies.
