What are the health risks if there is mold in your home?

Some molds are more hazardous than other molds, and different people have different responses to mold exposure. In particular, those with allergies, existing respiratory conditions or suppressed immune systems are especially susceptible to health problems from mold exposure. Additionally, infants and children, pregnant women, and the elderly can be sensitive to the effects of mold exposure. Some people that are exposed to mold experience allergic reactions, with symptoms similar to hay fever and the common cold but that last for longer periods, while others can experience aggravation to asthma. Researchers have identified that some fungi in indoor environments can induce allergic and irritant response, infectious disease, respiratory problems, hypersensitivity reactions, and organ toxicity. In addition, some molds produce chemicals called mycotoxins, which can cause flu-like symptoms.
