If temperature readings are in the red range you should speak with a doctor, whether or not there are symptoms.
If readings are in the yellow range and the baby or child also feels sick, you should speak to a doctor to find out whether or not you need to come in for further consultation and assessment.
If readings are in the green range and there are no other symptoms, there’s no need to consult a doctor.
When in doubt about symptoms, always consult your doctor.
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.
