Fungal Disease Awareness Week is October 1–5, 2018. CDC and partners have organized this week to highlight the importance of recognizing serious fungal diseases early enough in the course of a patient’s illness to provide life-saving treatment.
What is CDC doing to combat fungal diseases? We are taking action to prevent and control fungal diseases through a variety of domestic and international activities
Molds are microscopic organisms that play an important role in the breakdown of plant and animal matter. Outdoors, molds can be found in shady, damp areas, or places where leaves or other vegetation is decomposing. Indoor molds can grow on virtually any surface, as long as moisture, oxygen, and organic material are present. When molds are disturbed, they release tiny cells called spores into the surrounding air.
What do we know about health effects from mold? It is sometimes difficult to determine specific health outcomes from exposure to mold, since the effects depend on the characteristics, magnitude, and duration of the exposure. People who have an existing respiratory condition, such as asthma or allergies, are more likely to suffer adverse effects.
Microbial pollution is a key element of indoor air pollution. It is caused by hundreds of species of bacteria and fungi, in particular filamentous fungi (mould), growing indoors when sufficient moisture is available. This document provides a comprehensive review of the scientific evidence on health problems associated with building moisture and biological agents. The review concludes that the most important effects are increased prevalences of respiratory symptoms, allergies and asthma as well as perturbation of the immunological system
Cleaning up after a flood can pose health risks. You and your family should wait to re-enter your home until professionals tell you it is safe, with no structural, electrical or other hazards. Before you start cleanup activities, contact your insurance company and take pictures of the home and your belongings. Remember – drying your home and removing water-damaged items is your most important step for preventing mold damage.
During a flood cleanup, the indoor air quality in your home or office may appear to be the least of your problems. However, failure to remove contaminated materials and to reduce moisture and humidity can present serious long-term health risks. Standing water and wet materials are a breeding ground for microorganisms, such as viruses, bacteria, and mold. They can cause disease, trigger allergic reactions, and continue to damage materials long after the flood.
