Mold is a fungus that is prevalent in everyday life. Some molds are beneficial, but others can cause illness in some people, especially when they are growing in homes and workplaces. Mold can grow on almost any indoor surface where too much moisture is present, according to the Environmental Protection Agency. If the mold continues to grow unchecked, people living and working in the space may begin to develop symptoms of a mold-related illness.
Asthma
Exposure to mold can cause people with asthma to experience attacks or an increase in symptoms, according to the EPA. These symptoms develop because the mold spores can further irritate the respiratory tract when inhaled. Because of this risk, people who have asthma should avoid direct contact with mold and environments where mold is present.
Cold-Like Symptoms
Cold-like symptoms, such as a runny or stuffy nose, red, itchy, watery eyes and a sore throat, can also develop as a result of exposure to mold, according to the Centers for Disease Control (CDC). Although these symptoms are similar to a cold or seasonal allergies, they generally continue without improvement as long as the mold exposure continues.
Respiratory Problems
Mold illness can also cause difficulty breathing or other respiratory problems such as a cough, wheezing or shortness of breath. People with chronic lung conditions such as asthma and chronic obstructive pulmonary disease (COPD) are most likely to experience these effects, according to the CDC.
Rash
Exposure to mold can cause skin rashes or red, itchy skin, according to the California Department of Public Health. These rashes can occur after direct contact with mold or simply from being in an environment contaminated by mold.
Fungal Infections
In rare cases, mold exposure can cause fungal infections in the respiratory tract. These conditions are most common in people with compromised immune systems or those with underlying respiratory conditions, according to the CDC. Types of fungal infections that can develop include aspergilloma, allergic bronchopulmonary aspergillosis and invasive pulmonary aspergillosis. These infections generally cause severe respiratory symptoms and conditions, including pneumonia, fever and coughing up blood, according to the California Department of Public Health. Other symptoms include weight loss, headaches and bone pain. Pre-existing respiratory conditions will also generally worsen.
