Humidifier fever: A form of sick building syndrome that usually develops on Monday or the first workday of the week.
The hallmark of the disease is the sudden onset of fever. Other features may include muscle aches and pains and mild shortness of breath.
Humidifier fever can be caused by a number of different agents including amebas, bacteria, and fungi that may live in the moist environment of a humidifier.
Humidifier fever typically resolves once the patient is no longer exposed to the causative agent coming from the humidifier.
