The invention relates to a fever detection apparatus for detecting fever of a living being. A heart rate providing unit (3) provides a heart rate value and a peripheral physiological value providing unit (3) provides a peripheral physiological value wherein a heart rate characteristics determination unit (4) determines heart rate characteristics from the heart rate value and a peripheral characteristics determination unit (5) determines peripheral characteristics from the peripheral physiological value. A fever detection unit (6) detects fever depending on the heart rate characteristics and the peripheral characteristics. Since the heart rate characteristics and the peripheral characteristics are influenced by fever the fever detection apparatus can be used to reliably and preferentially unobtrusively detect fever.
