A3: Red flags of infectious diseases: fever, dehydration and confusion


Fever can be assessed by means of thermometers of various designs which may measure body temperature from various locations in the body (e.g. forehead skin, ear, rectum and mouth). The measured temperature is slightly different according to the site, so it is important to be clear from the thermometer manufacturer’s instructions what the normal range is for the device which is being used.


The core temperature of a well person tends to follow a diurnal variation with core temperature peaking in the late afternoon at up to 1°C (1.8F) higher than the temperature measured in the early morning. Also, for temperatures less then 37.5°C (99.5F) what is normal for one person may represent a fever in another who tends to run at a generally lower core temperature. This makes interpretation of lower levels of fever difficult, and in such cases it is very helpful to know what the normal range is for that person in health.


Increasingly the tympanic (eardrum) temperature is rapidly assessed by means of user-friendly hand-held devices. The normal ranges below represent tympanic readings in adults. The tympanic temperature range is higher than the oral range by up to 0.7°C, and so the guidance below should be adjusted accordingly if oral readings are being interpreted. It must also be remembered that the normal range of temperature for children is slightly higher than for adults (see below).
