[Workplace-associated fever].

Febrile conditions often have an infectious etiology. However, there are also fevers associated with occupational exposures. A detailed occupational history can hold the key to the diagnosis. In the case of exposure to organic dusts, the development of hypersensitivity pneumonitis (HP) is possible. Thus, HP should be considered in the presence of interstitial lung disease of unclear etiology. Failure to recognize this can have dramatic consequences and, in extreme cases, lead to lung transplantation. Differentially, organic dust toxic syndrome (ODTS) must be considered. The syndrome of metal fume fever provoked by inhalation of inorganic substances is usually benign and self-limiting. The disease manifests with fever, cough, and flu-like sensations.
