Decocidio is a type of disorder that happens when someone gets too much exposure to things like dust, pollen, or other small particles in the air that can cause allergies and breathing problems. People with decocidio can have trouble breathing, and can even develop asthma or other breathing related illnesses. These things can be prevented by staying away from places that have a lot of dust, pollen, or other small particles in the air, like construction sites. Wearing a mask over your mouth and nose can also help protect you from the things in the air that can cause problems.
