Exposure to Mould and Moisture Damage Is a Potential Risk Factor for the Development of Respiratory Diseases Opinion

Abstract

Adverse health effects due to indoor air moisture damage has been extensively studied already for thirty years. Expose to dampness microbiota (DM) in buildings is a risk factor for newly onset asthma and other respiratory problems. This exposure increases the rate of upper and lower respiratory tract infections because the function of the cilia cells and the integrity of mucosal layer becomes compromised. The breach of the first defense barrier of innate immunity leads to susceptibility to inhaled impurities and pathogens. Dampness and mould-associated asthma may present with several clinical peculiarities. This asthma may be resistant to treatment, the symptoms may exacerbate during periods with increased outdoor air humidity and rainfalls and this asthma may be associated with chronic obstructive pulmonary disease (COPD). It has been generally recognized that persons sensitized to DM should avoid new and repeated exposure to moldy environment. This recommendation is important especially during the current SARS-CoV2 pandemic.
