What causes a Fever?

Fever is a raised body temperature in response to illness, facilitating and accelerating recovery from causes like infection, heat stroke and dehydration.

It is usually associated with other fever symptoms that may help identify the cause of the illness.

What are the symptoms of a fever?

  • a fever temperature is above 37.5˚C
  • hot and flushed face
  • headache
  • body aches
  • feeling light-headed
  • sweating and thirst
  • head, neck and body may feel hot while hands and feet are cold
  • shivering
  • unexplained crying and irritability (in children)
  • confusion (especially in the elderly)

How to reduce a fever?

  • Rest, preferably in bed, in a cool and well-ventilated room.
  • Take plenty of liquids like water, fruit juices and clear soups.
  • Remove thick clothes or blankets.
  • Take a cool shower.
  • For children, sponge the body with tap or lukewarm water to cool down the body especially if the temperature is above 38.5˚C. Stop sponging when the child shivers. Cover him up and wait a while before continuing. Generally, you should not sponge a child for more than 30 minutes at one go.
  • Eat as usual or according to your appetite.
  • Take your body temperature every 6 hours. To take an accurate reading of oral temperature, do not drink or eat anything half an hour before.
  • Take anti-fever medicines such as paracetamol. Do not use aspirin for children under 16 years of age. Consult your pharmacist before buying these over-the-counter medicines.
