For many Nigerian parents, a hot child means malaria. Sometimes it is. Sometimes the fever is caused by a cold, an ear infection, pneumonia or typhoid. Malaria in young children can be mild one day and life-threatening the next, so getting the diagnosis and treatment right matters. This guide explains the signs of malaria in children under five, why testing comes first, how to give medicine correctly and how to protect your child.

Why young children are at higher risk

Children under five have not yet built up partial immunity to malaria. Their bodies cannot control the parasites as well as older children and adults. As a result, malaria in young children can progress to severe malaria quickly, sometimes within a day. Most malaria deaths in Africa occur in children under five.

Babies under six months have some protection from their mothers, but they can still get malaria and need prompt care.

Common signs of malaria in young children

Children may not complain of the classic symptoms. Watch for:

  • Fever, or a hot body, sometimes coming and going
  • Irritability and crying more than usual
  • Poor feeding or refusing to breastfeed
  • Vomiting
  • Diarrhoea
  • Cough
  • Sleepiness or unusual tiredness
  • Chills or shivering
  • Pale skin

These signs overlap with many other childhood illnesses. A test is the only way to be sure.

Danger signs that need emergency care

Take your child to hospital immediately if they:

  • Have a fit or convulsion
  • Are very sleepy or difficult to wake
  • Cannot drink or breastfeed
  • Vomit everything
  • Have fast or difficult breathing
  • Have very pale palms or lips
  • Pass dark urine or very little urine

These are signs of severe malaria. They need injectable treatment in hospital.

Test before you treat

Every child with fever should be tested for malaria before treatment. A rapid diagnostic test from a finger or heel prick gives a result in about 15 to 20 minutes. Many pharmacies, clinics and primary health centres offer testing.

Testing matters because:

  • If the test is positive, your child gets the right medicine quickly.
  • If it is negative, the health worker can look for the real cause, such as pneumonia, which needs different treatment.
  • Giving antimalarials without a test can delay treatment for other serious illnesses.

Treatment for uncomplicated malaria

Dosing steps for treating malaria in young children with artemether-lumefantrine

 

Ask the pharmacist to weigh your child and confirm the dose.

Uncomplicated malaria in children is treated with an artemisinin-based combination therapy (ACT). The most common in Nigeria is artemether-lumefantrine1. Others include artesunate-amodiaquine and dihydroartemisinin-piperaquine.

Important points:

  • Dose by weight. Children’s doses depend on body weight. Ask the health worker to weigh your child.
  • Complete all doses. Artemether-lumefantrine is given twice a day for three days, six doses in total. Do not stop when the fever goes.
  • Give with food or milk. Lumefantrine is absorbed better with a little fatty food or breast milk.
  • Use child-friendly forms. Dispersible tablets dissolve in a little water and are easier for young children.

If your child vomits a dose

If your child vomits within 30 minutes of a dose, give the same dose again. If they vomit again, or cannot keep medicine down, take them to a health facility. Repeated vomiting can be a sign of severe malaria and means the medicine is not being absorbed.

 

HUBPHARM PHARMACIST’S NOTE

Getting the dose right for a small child is the most common worry we hear. Splitting adult tablets or guessing doses leads to treatment failure. Message a HubPharm pharmacist with your child’s weight and age. We will confirm the correct dispersible ACT, show you how to dissolve and give each dose, explain what to do if your child vomits and give you a simple six-dose checklist. We also supply paracetamol syrup, test kits and treated nets for the whole family.

 

Managing fever at home

Alongside antimalarial treatment:

  • Give paracetamol at the right dose2 for your child’s age or weight to bring down fever
  • Dress your child in light clothing
  • Sponge with lukewarm water, not cold water
  • Offer plenty of fluids and continue breastfeeding
  • Offer small, frequent meals

Never give aspirin to children. Avoid putting children in cold water or using alcohol rubs.

Malaria in young children under six months

Young babies can get malaria, especially if their mothers had malaria during pregnancy or live in high-transmission areas. Signs may be subtle: poor feeding, unusual sleepiness, fever, irritability or jaundice. Any baby under two months with fever needs urgent assessment, whatever the cause. Doses of antimalarials for small babies must be calculated carefully by a health worker.

Malaria and other illnesses together

Children can have malaria and another illness at the same time, such as pneumonia or a urinary infection. If your child has a cough, fast breathing, diarrhoea or ear pain alongside a positive malaria test, the health worker should check for these too. Treating malaria alone may not be enough.

When to return

Return to the health worker if:

  • The fever does not improve after two days of treatment
  • Your child gets worse at any time
  • Any danger sign appears
  • Fever comes back within a few weeks of treatment

A fever that continues may mean the medicine was not effective, the dose was wrong or the illness is something other than malaria.

Malaria in young children and anaemia

Repeated malaria infections destroy red blood cells and can cause anaemia. Children with anaemia may be pale, tired and breathless. Severe anaemia is dangerous and may need a blood transfusion. Iron-rich foods, such as beans, green vegetables, eggs and meat, help recovery. Your health worker may also prescribe iron or other supplements.

Taking care of the net

A torn or poorly hung net gives little protection. Tuck the edges under the mattress or mat every night. Repair holes with thread or tape. Wash the net gently with mild soap, no more than a few times a year, and dry it in the shade. Make sure young children sleep under the net from early evening, when mosquitoes start biting. These habits greatly reduce malaria in young children.

Talking to your child’s caregivers

Nannies, grandparents and day-care staff often look after young children. Make sure they know the danger signs and where the nearest health facility is. Leave your phone number and agree on what they should do if your child develops a fever while you are away. Everyone caring for your child plays a part in preventing malaria in young children from becoming severe.

Preventing malaria in young children

Prevention is the best protection:

  • Sleep under an insecticide-treated net3 every night, all year round
  • Seasonal malaria chemoprevention (SMC) in eligible areas, given monthly during the rainy season to children aged 3 to 59 months
  • Malaria vaccine, being introduced in parts of Nigeria for young children
  • Clear stagnant water around the home
  • Screen windows and doors where possible
  • Long sleeves in the evening for older babies and toddlers

Myths about malaria in young children

“Every fever is malaria.” Many fevers have other causes. Test first.

“Herbal baths cure malaria.” Herbal baths do not kill malaria parasites. Use proven medicines.

“You can stop medicine once the fever goes.” Stopping early can let malaria return and lead to resistance.

“A strong injection works faster for children.” Injections are for severe malaria in hospital, not for routine cases.

Keep a fever record

Write down the time and temperature each time your child has a fever, the medicines given and the doses. Bring the record to the health worker. It helps them decide quickly whether treatment is working.

Ask before giving any medicine

Always tell the pharmacist your child’s age and weight before buying any medicine for fever, cough or diarrhoea.

Getting help

Prompt testing and correct treatment protect your child from malaria in young children turning severe. The WHO fact sheet on malaria has more information, and our malaria articles cover testing, nets and SMC. For child-friendly antimalarials, paracetamol syrup or test kits, message a HubPharm pharmacist or chat with Afiya on WhatsApp.
