Fever & Common Illnesses
A fever or a cough can be worrying, especially at night. Dr Nisa Khalil, Consultant Paediatrician, helps you know what is normal, the signs that need a doctor, and how to keep your child comfortable at home.
A fever is usually a temperature of 38°C or higher. It is not an illness in itself, it is a sign that your child’s body is doing its job and fighting an infection. How your child looks and behaves matters more than the exact number on the thermometer.
What counts as a fever
A temperature of 38°C or higher, measured under the arm or in the ear with a digital thermometer. A warm forehead by touch alone is not a reliable guide.
How your child seems
Often more telling than the number. A child who is alert, drinking, and settles with rest is usually coping well. A child who is very drowsy, floppy, or hard to rouse needs to be seen.
Most fevers in children are caused by common viral infections and settle on their own within a few days.
Common illnesses we help with
Beyond fever, most childhood illnesses are common, mild, and pass on their own. Dr Nisa helps you tell the everyday from the concerning, and know when a check is worth it.
Coughs & colds
Runny nose, cough, and often a mild fever, usually from a common virus. Most settle within a week or so with rest and fluids.
Ear infections
Ear pain, tugging at the ear, or a fever after a cold. Many clear on their own; some need a check if pain or fever lingers.
Sore throats
Often viral and settle on their own. Some need a check, especially with a high fever, trouble swallowing, or swollen glands.
Tummy bugs
Vomiting and diarrhoea from a stomach virus. The main aim is keeping your child hydrated with small, frequent sips.
Hand, foot & mouth
A common viral illness with mouth ulcers and spots on the hands and feet. Uncomfortable, but usually mild and short-lived.
Skin rashes
Most childhood rashes are harmless and viral. A rash that does not fade when pressed always needs to be seen urgently.
This is not a full list. If you are ever unsure about a symptom, it is always okay to ask.
Most fevers are mild, but some signs need prompt medical care. Please see a doctor urgently, or go to the nearest emergency department, if your child:
Is under 3 months old and has any fever (38°C or higher)
Is very drowsy, floppy, or hard to wake, or is struggling to breathe
Has a rash that does not fade when pressed, a stiff neck, or a fit or seizure
Is not drinking or has far fewer wet nappies, or the fever lasts more than 5 days
Trust your instincts. If your child looks seriously unwell, do not wait for these signs, get medical help straight away.
Calm, evidence-based care when your child is unwell, from working out what is causing the illness to knowing when it needs more than home care.

Most fevers can be managed comfortably at home. The aim is not to force the temperature down, but to keep your child comfortable while their body fights the infection.
1
Offer plenty of fluids
Small, frequent sips of water, milk, or their usual drink. Staying hydrated matters more than eating.
2
Keep them comfortable
Dress them lightly and keep the room cool, not cold. Let them rest as much as they need.
3
Medicine for comfort, if needed
Paracetamol or ibuprofen can ease aches and distress. They are for comfort, not to cure the fever. Never give aspirin to a child, and always follow the dose for your child’s weight.
4
Know when to get help
Keep watching how your child looks, not just the thermometer. If any red flag above appears, or you feel worried, seek medical advice.
Is a high fever dangerous in itself?
Should I alternate paracetamol and ibuprofen?
What is a febrile fit, and is it dangerous?
When should I worry about dengue?
Does my child need antibiotics?
Book an appointment and Dr Nisa will help you work out what is going on and what your child needs.
