Adverse respiratory health effects are associated with occupancy in buildings with moisture and mold damage. Infants may develop respiratory symptoms due to exposure to a specific type of fungal mold, called Penicillium. Signs that an infant may have mold-related respiratory problems include (but are not limited to) a persistent cough and wheeze. Increased exposure increases the probability of developing respiratory symptoms during their first year of life.  Studies have shown that a correlation exists between the probability of developing asthma and increased exposure to Penicillium. The levels are deemed no mold  to low level, from low  to intermediate, and intermediate  to high. Infants in homes with mold have a much greater risk of developing asthma and allergic rhinitis.
Mold exposures have a variety of health effects depending on the person. Some people are more sensitive to mold than others. Exposure to mold can cause several health issues such as; throat irritation, nasal stuffiness, eye irritation, cough, and wheezing, as well as skin irritation in some cases.  Exposure to mold may also cause heightened sensitivity depending on the time and nature of exposure.  People at higher risk for mold allergies are people with chronic lung illnesses and weak immune systems, which can often result in more severe reactions when exposed to mold.
There has been sufficient evidence that damp indoor environments are correlated with upper respiratory tract symptoms such as coughing, and wheezing in people with asthma.
