How much mold does it take to make me sick?

It depends on the situation and the person. This question is difficult to answer in the same way it's hard to say how much sun causes a sunburn: the amount varies from person to person. What one person can tolerate with little or no effect may cause symptoms in another individual.

The long-term presence of indoor mold may eventually become unhealthy for anyone. Those with special health concerns should consult a medical doctor if they feel their health is affected by indoor mold. The following types of people may be affected sooner and more severely than others:

• Babies and children
• Elderly persons
• Individuals with chronic respiratory conditions or allergies or asthma
• Persons having weakened immune systems (for example, people with HIV or AIDS, chemotherapy patients, or organ transplant recipients)
