<unk> s are work-related,<unk>  conditions that have been caused or made worse by the materials a person is exposed to within the workplace. It includes a broad group of<unk> s, including occupational asthma, industrial bronchitis, chronic obstructive pulmonary<unk>  (COPD), bronchiolitis obliterans, inhalation injury, interstitial<unk><unk> s (such as pneumoconiosis, hypersensitivity pneumonitis,<unk>  fibrosis), infections,<unk>  cancer and mesothelioma. These<unk> s can be caused directly or due to immunological response to an exposure to a variety of dusts, chemicals, proteins or organisms. Occupational cases of interstitial<unk><unk>  may be misdiagnosed as COPD, idiopathic pulmonary fibrosis, or a myriad of other<unk> s; leading to a delay in identification of the causative agent.
