There are many mold types. Most typical indoor air exposures to mold do not present a risk of adverse health effects. But some molds can cause adverse effects by producing allergens (substances that can cause allergic reactions). Potential health concerns are important reasons to prevent mold growth and to remove mold in existing problem areas.
The body exhibits three basic responses to contaminants:
1. Allergic response – Humans experience allergic-type reactions to fungi creating markers (anti-bodies) in their blood.
2. Disease response – Occurs when spores or hyphal fragments enter deeply into the lungs in sufficient quantities or penetrates the skin, a disease results and the body reacts. Usually in immune-compromised persons.
3. Toxic response – When humans come into contact with toxins, severe damage can occur. Some fungi create toxins which are irritants and carcinogens. Some fungi can be extremely dangerous in high enough doses.
The onset of allergic reactions to mold can be either immediate or delayed. Allergic responses include hay fever-type symptoms such as runny nose and red eyes or be much more severe. The overwhelming consensus is that when mold in found indoors, it must be removed
