Yes, mold is divided into three types:Allergenic MoldsPathogenic MoldsToxigenic MoldsAllergenic Molds do not usually produce any life-threatening issues, and will normally be a threat mainly to those who already suffer from some form of allergies or asthma. The physical responses are relatively mild, usually scratchy throats, eye and nasal irritations, and skin rashes. Pathogenic Molds can produce some level of infection. People with depressed immune systems are usually the hardest hit, and high levels of exposure can result in hypersensitivity pneumonitis. Toxigenic Molds are the ones everybody naturally fears. Commonly known as Black Mold or Toxic Mold, they can cause serious health effects for almost everyone. Toxic Molds can cause cancer, lung disease, and in rare, high exposure cases, even death.
