If there are symptoms, such as unusual irritability, unresponsiveness, weakness, vomiting, diarrhea, dry skin, unusual thirst, seizure, loss of appetite, or changes in activity, you should contact a doctor regardless of whether the thermometer shows green, yellow, or red. If…

NICE guidelines (NICE 2007) suggest that the cutoff for high fever should be 38.0°C (rectal) for infants less than 3 months of age and 39°C (rectal) for infants between 3 and 6 months of age. When adjusted to an equivalent…

For children in the age range of 0 to 3 months, temperatures above 38 C (rectal) often mean that there is an infection, so they need immediate attention. In very young babies, any temperature elevation should be considered serious (red zone).…

The cutoff of 37.7 is specific to the Thermoscan Infrared Ear thermometer only. Different digital thermometers are programmed to give different readouts from different body sites. Since the Thermoscan Infrared Ear thermometer displays an oral equivalent display reading, the cutoff…

High fever in children should be a concern. Consult a physician if a child’s temperature is in the elevated (fever) or high temperature (high fever) range, especially if the child has symptoms along with fever. High fever usually is a…

The tops of “normal” temperature ranges, which are based on statistical sampling of healthy people, are not the same as fever as defined by medical criteria. The Age Smart color scale is not meant to show whether temperatures are within…

The differences are small, and many healthy children have temperatures similar to temperatures in adults and vice versa. One large study found that, on average, body temperature gets lower as people get older (Chamberlain et al 1995), but other studies…

Temperature readings vary from one healthy person to another and are influenced by factors such as age, gender, and ambient temperature. Temperature readings vary even in the same person at different times. Therefore, normal body temperatures can only be given…
