According to the CDC, the duration and extent of flooding and the number of structures flooded as a result of Hurricanes Katrina and Rita make the likelihood of massive mold contamination in buildings a certainty. Some have estimated that as many as 60 to 80 percent of residential structures in New Orleans sustained severe flood damage. Outside New Orleans, extensive hurricane damage without prolonged flooding occurred. This more typical pattern of damage from wind and rain will result in problems with mold, but will not be as extensive as in New Orleans.

CDC's online publication provides information on how to limit exposure to mold and how to identify and prevent mold-related health effects. It is designed to be especially useful to public health practitioners, health care providers, building managers, custodians, and others who are responsible for building maintenance. Contractors and other professionals who respond to mold or moisture problems in buildings will also find the information useful.

The document include up-to-date information on assessing exposure, cleanup and prevention, personal protective equipment, health effects, and public health strategies and recommendations.
