Pyrexia

Pyrexia is another word for fever.

Pyrexia is but a sign of the intensity of the activities of the infective agent, and by artificially reducing the body heat we really do not lessen the virulence of the poison, as shown by the rise of the temperature again as soon as the action of the antipyretic subsides.

The least defined pyrexiae were the continued fevers, divided mainly into typhus, enteric (typhoid) and relapsing.
