Alveoli are the primary structure affected by<unk> . Any particles that are smaller than 5 microns can enter the alveoli of the lungs. These tiny air sacs facilitate the passage of oxygen from inhaled air to the bloodstream. In the case of<unk> , it is more difficult for this exchange of oxygen to occur since irritants have caused inflammation of the alveoli. Due to the lack of a definitive determination of a single irritant causing<unk> , there are several possible causes. *Viral infection. Measles can cause severe<unk> , and ribavirin has been proposed as a possible treatment. CMV is another cause. *Pneumonia * Radiation therapy * Inhaling chemicals, such as sodium hydroxide *Interstitial lung disease *Sepsis * Adverse reaction to medications * Hypersensitivity to inhaled agents * Inhalation of spores of some species of mushroom (bronchoalveolar allergic syndrome) *Mercury exposure *Smoking * Overexposure to chlorine *Bronchial obstruction (obstructive<unk>  or post-obstructive<unk>  *Ascariasis (during parasite migration) * Aspirin overdose, some antibiotics, and chemotherapy drugs * “Farmer’s lung” and “hot tub lung” are common names for types of hypersensitivity<unk>  that result from exposure to some types of thermophilic actinomyces, mycobacteria and molds. * Avian proteins in bird feces and feathers * Whole body or chest radiation therapy used for cancer treatment
