What does fever mean in Celsius?

Body temperature changes during the day and differs by measurement site. An oral, ear, forehead, or underarm reading may not match another method, so use the thermometer instructions and record how it was taken. A single reading cannot show whether the cause is a respiratory infection, a skin problem, dehydration, or overheating. Chills, sweating, aches, cough, sore throat, vomiting, or pain help clinicians understand the picture. For babies, older adults, and people with reduced immunity, symptoms and behaviour can be concerning even when the number is not striking.

Use the same thermometer and method when checking again, allow the person to rest, and encourage suitable fluids. Light clothing and a comfortable room can reduce discomfort. Paracetamol may help if appropriate; follow the product directions and avoid duplicate ingredients. Do not use alcohol rubs or ice to force the temperature down. Write down readings, timing, medicines, fluid intake, urination, and new symptoms so a clinician can see the trend.

Seek emergency help for difficulty breathing, blue or grey skin, confusion, seizure, fainting, severe dehydration, stiff neck, or inability to wake. Arrange prompt medical assessment for a young infant with fever, a person with a weakened immune system, a worsening illness, or a fever that does not settle. Contact a clinician when the reading conflicts with how unwell the person feels, the thermometer seems unreliable, or drinking and urination are reduced.

Ask which measurement method is most suitable, how often to recheck, what medicine and dose are safe, and which symptoms matter more than the number. Provide the Celsius readings with their times and measurement sites.
