Allergic reactions are the most common mold health problem from exposure such as allergic rhinitis, dermatitis, asthma associated aggravation and hypersensitivity pneumonitis. A toxic affect may cause flu-like symptoms such as fever, runny nose, headache, fatigue and muscle pain. A lack of concentration and mood swings have also been reported. Rare fungal infections are usually suffered by the seriously immune compromised.
Some individuals will have no reaction when exposed to molds while other, susceptible, individuals may suffer from more severe health risk, or hazard. This is a subject under continuous and evolving study by experts.
