Common Questions
Can mold make you sick?
Answer
It can. The effects EPA and CDC describe most often are allergic reactions (sneezing, runny nose, red eyes, skin rash), asthma attacks in people who are allergic to mold, and irritation of the eyes, skin, nose and throat. People with weakened immune systems can develop serious infections, and CDC advises them to stay away from moldy sites.
In moldy buildings, occupants also report headaches and breathing difficulties; EPA says these could potentially be associated with mold exposure. Allergic reactions can happen whether the mold is alive or dead.
Only a doctor can say whether mold is causing someone's symptoms. A mold assessor can tell you where mold is and how much, not whether it's making you ill.
