Flooding events, particularly those caused by hurricanes and other large storm events, are increasingly fueled by climate change. Stormwater intrusion into homes creates ideal conditions for mold growth. Homes inundated by floodwaters become vulnerable to production of mold spores, particulate matter, and volatile organic compounds, all of which trigger a variety of poor health outcomes. Disadvantaged communities often bear the brunt of these hazards and face additional challenges due to limited resources for effective remediation. Moisture control is the cornerstone of effective mold remediation. Removal of porous material and rapid initiation of dehumidification reduce potentially harmful exposures. During cleanup, protective measures, especially the use of N95 respirators, reduce the inhalation of particulate matter from mold and from the remediation process itself. Individuals with immunodeficiency or respiratory conditions should be excluded from damp environments and remediation activities. Public health approaches are needed after flooding events, including prioritization of remediation in resource-limited communities and communication on effective, ineffective, and potentially harmful strategies in addressing mold exposure.
