10 Common Childhood Illnesses And How To Treat Them.

10 Common Childhood Illnesses And How To Treat Them

GP Dr Sarah Brewer explores some of the most frequent illnesses to strike children, and helps you to recognise them.



Tonsillitis, an infection of the tonsils, can be caused by a virus or bacteria, but most cases are viral. Symptoms include a sore throat with red, swollen tonsils, pain on swallowing, fever, coughing and headache. The glands in the neck are often swollen too, and there may be spots of pus on the tonsils.

Who gets it? It is most common in children aged five to 15. Infection is spread from person to person by coughing, sneezing or picking up germs after shaking hands or touching.

Treatment: See your GP for a throat swab to check if your child has a bacterial infection, which would need antibiotics. If your child has frequent and severe tonsillitis, your GP may suggest an operation to remove her tonsils. Paracetamol, ibuprofen, throat lozenges or throat sprays will help symptoms.


Whooping cough (Pertussis)

This is a bacterial infection of the airways that starts with cold-like symptoms and then progresses to severe coughing spasms. The characteristic ‘whoop’ sound occurs when the poorly child desperately tries to take in air between coughs.

Who gets it? Whooping cough is spread by coughing and sneezing. Vaccination has made whooping cough much less common in infants and young children, but it is making a come-back in older children who were vaccinated more than five to 10 years ago.

Treatment: See your GP as soon as possible for throat swabs or a blood test to confirm diagnosis. Your child will need antibiotics.


Slapped cheek syndrome

Also known as fifth disease, slapped cheek syndrome is a viral disease that triggers mild cold-like symptoms, such as a sore throat and headache, as well as one or two red cheeks, as if slapped. Your child can also develop a rash elsewhere on her body and may experience joint pains.

Who gets it? It usually occurs in children aged two to 14 years and is more common during the spring.

Treatment: Paracetamol if needed.


Chicken pox

This highly contagious viral infection causes fever, headache and a red rash before developing into itchy, fluid-filled blisters. Some children get away with just a few spots, but others get them everywhere, including inside the mouth and on the scalp.

Who gets it? Mostly children under 10 years. Infection is spread by inhaling droplets of the virus from the air, but also by direct contact with the blister fluids – perhaps by touching clothing that the blisters have rubbed against.

Treatment: See your GP if you’re not sure of the diagnosis. Paracetamol will help with the pain and fever, while soothing lotions will relieve itching.


Hand, foot and mouth disease

This is a viral disease which causes a mild, non-itchy rash on the palms of the hands and soles of the feet. Some children also develop mouth ulcers and feel unwell.

Who gets it? Mainly children under 10 years of age, but older children are occasionally affected. You can catch it more than once.

Treatment: Paracetamol when needed.


Scarlet fever

This highly contagious bacterial infection starts with a throat or skin infection and leads to a fever, flushed face and wide-spread, pink-red rash. The rash feels rough, like sandpaper, and may be itchy. It’s caught through contact with an infectious person, or by touching infected items, such as door handles.

Who gets it? Children between the ages of four and eight years are more usually affected. Once they are 10, most children have developed a natural immunity to the toxins.

Treatment: See your GP as antibiotics are needed within 10 days. If not treated, immune reactions can lead to complications such as kidney problems or rheumatic fever.



Gastroenteritis is usually caused by a virus, but can be bacterial too. It triggers vomiting, diarrhoea, stomach pains and sometimes fever. It’s spread by touching the hands of someone who’s struck down with the illness, from eating infected food or by swimming in water containing the germs.

Who gets it? Children of any age can be affected.

Treatment: Replace lost fluids and salts with oral rehydration fluids, which you can buy in sachets from pharmacies or on prescription. See your GP if you see blood in your child’s poo, she develops a fever or does not improve within a couple of days. Always seek medical advice if a child passes six or more diarrhoea stools – or vomits three times or more – in 24 hours as young children can quickly become dehydrated.


Ear infections

An infection of the middle ear is usually viral but can be bacterial. Symptoms would include earache, reduced hearing, tinnitus and fever. The eardrum may perforate to discharge fluid and relieve the pressure pain, although it heals within a month.

Who gets it? Middle ear infections are most common in children aged six months to five years, usually after having a bad cold.

Treatment: Seek medical advice if your child is in severe pain or has a high temperature. If you see a discharge from her ear, cover it with a clean, dry gauze pad and contact your doctor, who may prescribe antibiotics. Recurrent middle ear infection may be associated with glue ear so tell your doctor if your child seems to have reduced hearing.



Impetigo is a highly contagious bacterial skin infection picked up through close contact with a child with the illness, or by touching infected toys, clothes or towels. Small red spots appear on the face, especially around the nose and mouth, neck or hands. The spots often cluster or merge, blister, then form a characteristic golden crust. New spots can appear over several days or weeks.

Who gets it? It affects two per cent of children aged five to 14, and three per cent of those aged four years and younger. It’s more common in children suffering from eczema, insect bites or nappy rash, as infection can enter the skin more easily.

Treatment: An antibiotic cream may be enough, but your GP may also prescribe oral antibiotics if your child feels unwell or has a fever. Keep kids away from school until all spots have crusted over, or for at least 48 hours after starting treatment. Make sure infected children have their own flannels and towels.



Flu is a viral infection of the nose, throat, ears and sinuses. Look out for your child developing a stuffy, runny nose, sore throat, cough and high temperature. She may also develop a headache and severe aches and pains, plus exhaustion.

Who gets it? Viruses are transmitted by coughing, sneezing and by hand contact, and can survive on objects such as door handles for several hours. Flu tends to occur as seasonal epidemics.

Treatment: Paracetamol as needed. See your GP if symptoms worsen or last longer than a week, or if your child develops trouble breathing. Also visit your GP if your child has a medical condition which can be difficult to control, such as asthma or diabetes. An annual flu vaccination may be suggested in some cases.
