1. Why Do Children Get Sick So Often?
If your child seems to catch a cold just when they have recovered from the last one, you are not alone.
Young children can get infections quite often, especially when they start school, daycare or spend more time around other children. Their immune systems are still developing, and close contact makes it easier for infections to spread.
Some childhood illnesses are mild and usually get better with proper care. Others can become serious and need medical attention.
Common childhood illnesses include:
- Colds and other viral respiratory infections
- Fever caused by infections
- Cough and throat infections
- Ear infections
- Diarrhoea and vomiting
- Hand, foot and mouth disease
- Chickenpox
- Measles
- Pneumonia
- Certain skin infections
WHO's approach to childhood illness places particular importance on conditions such as pneumonia, diarrhoea, measles and malnutrition because they can cause serious illness in children.
The good news is that parents can take several simple steps to reduce the risk of many infections.
Good hand hygiene, safe food and water, vaccination, proper nutrition, clean surroundings and timely medical care all play an important role in protecting children.
At the same time, remember that getting sick occasionally does not necessarily mean your child's immunity is weak. Children will naturally come into contact with many germs as they grow.
The important thing is knowing what you can prevent, what you can safely manage at home and when your child needs to see a doctor.
2. Common Respiratory Illnesses: Colds, Coughs and Pneumonia
Cough, runny nose, sneezing and fever are some of the most common symptoms parents see in young children.
Many respiratory infections are caused by viruses and improve with time and supportive care. However, some infections can become more serious.
Common cold
A child with a cold may have:
- Runny or blocked nose
- Sneezing
- Mild cough
- Sore throat
- Mild fever
- Reduced appetite
- Tiredness
Most uncomplicated colds improve with rest, fluids and supportive care.
You do not need to give antibiotics every time your child has a cough or cold. Antibiotics do not treat viral infections and should only be used when prescribed for an appropriate bacterial infection.
Ear infections
Some children develop an ear infection during or after a respiratory infection.
Your child may:
- Complain of ear pain
- Pull or rub their ear
- Become unusually irritable
- Have difficulty sleeping
- Have fever
- Have trouble hearing temporarily
If your child has significant ear pain, fever or symptoms that are getting worse, consult a healthcare professional.
Pneumonia
Pneumonia is an infection affecting the lungs. It can be caused by viruses, bacteria and other infectious organisms.
Watch for symptoms such as:
- Cough
- Difficulty breathing
- Fast breathing
- Chest pain
- Fever
- Unusual tiredness
- Poor feeding or reduced appetite in younger children
Breathing difficulty is particularly important. If your child is struggling to breathe, breathing unusually fast, becoming very sleepy or showing other signs of serious illness, do not wait for the symptoms to settle at home.
Pneumonia can often be prevented through vaccination, adequate nutrition, good hygiene and reducing exposure to household air pollution and tobacco smoke.
How can parents reduce respiratory infections?
You cannot prevent every cold or cough, but you can reduce the spread of infections.
Encourage your child to:
- Wash their hands regularly.
- Cover their mouth and nose when coughing or sneezing.
- Avoid sharing cups, bottles and utensils with someone who is sick.
- Stay away from people who are unwell when possible.
- Avoid exposure to cigarette smoke.
- Stay up to date with recommended vaccinations.
If your child is too young to follow these habits independently, adults around the child should practise them.
3. Diarrhoea, Vomiting and Stomach Infections
Few things make parents more worried than seeing their child repeatedly vomit or have loose stools.
Diarrhoea and vomiting can happen because of infections, contaminated food or water, and other causes. The main concern is not just the loose stools themselves. The bigger concern is dehydration.
Diarrhoea can cause the body to lose water and important salts. Young children can become dehydrated faster than adults. Safe drinking water, sanitation and good hygiene can help prevent many diarrhoeal infections.
What should parents watch for?
Signs of dehydration may include:
- Dry mouth or tongue
- Reduced urination
- Fewer wet nappies in babies
- No tears while crying
- Unusual sleepiness or weakness
- Sunken-looking eyes
- Excessive thirst in older children
If your child has diarrhoea, continue giving fluids as advised by your healthcare professional. Oral rehydration solution (ORS) may be recommended to replace lost fluids and salts.
Continue feeding your child unless your doctor advises otherwise. For breastfed babies, breastfeeding should generally be continued during diarrhoeal illness.
For children with diarrhoea, zinc supplementation may also be recommended as part of treatment, depending on the child's age and local clinical guidance. Ask your child's doctor about the appropriate treatment rather than choosing medicines yourself. WHO's updated guidance covers management of diarrhoea and pneumonia in children up to 10 years of age.
How can you prevent stomach infections?
Prevention starts at home.
Make handwashing a habit, especially:
- Before preparing food
- Before eating
- Before feeding a young child
- After using the toilet
- After changing a baby's diaper
- After cleaning up vomit or stools
Also make sure drinking water is safe and food is prepared and stored hygienically.
Do not give children food that has been left out or stored improperly.
And avoid giving anti-diarrhoeal medicines or antibiotics without medical advice. The right treatment depends on the child's age, symptoms and cause of the illness.
4. Fever, Viral Infections and Common Childhood Rashes
Fever can be frightening, especially when your child feels hot and uncomfortable.
But fever itself is usually a sign that the body is responding to an infection. It is important to look at your child's overall condition, not just the number on the thermometer.
A child with a mild viral illness may have fever along with:
- Runny nose
- Cough
- Sore throat
- Body aches
- Tiredness
- Reduced appetite
Many viral infections improve with supportive care. However, the cause of fever cannot always be identified just by looking at the symptoms.
What about childhood rashes?
Children can develop rashes for many different reasons. Some are caused by common viral infections, while others may be related to allergies, insect bites, skin irritation or other conditions.
For example, chickenpox typically causes an itchy rash that progresses through different stages. Measles can cause fever followed by a characteristic rash, along with symptoms such as cough, runny nose and red eyes.
Measles is particularly important to prevent because it can lead to complications including pneumonia, severe diarrhoea and dehydration. Vaccination is the most important way to prevent measles.
If your child develops a new rash along with high fever, breathing difficulty, unusual sleepiness, swelling, severe pain or other worrying symptoms, seek medical advice.
Should every fever be treated with medicine?
Not necessarily.
The need for treatment depends on your child's age, temperature, symptoms, medical history and overall condition.
Never give a child aspirin unless specifically instructed by a doctor. Also, do not give adult medicines to children without medical advice.
If your baby is very young and develops a fever, seek medical advice promptly because fever in young infants can sometimes indicate a serious infection.
5. Simple Ways to Prevent Common Childhood Illnesses
You cannot keep your child away from every germ, but you can build healthy habits that reduce the risk of many infections.
1. Keep vaccinations up to date
Vaccination protects children from several serious infections.
Follow the vaccination schedule recommended by your child's healthcare professional and keep the vaccination record safely.
Vaccination is particularly important for preventing diseases such as measles, and vaccines against conditions such as pertussis, pneumococcal disease and Hib also help reduce the risk of serious respiratory illness.
2. Make handwashing a daily habit
Teach your child to wash their hands with soap and water.
Make it part of their routine rather than something they do only when they are visibly dirty.
3. Provide a balanced diet
Good nutrition supports normal growth and helps the body maintain its natural defences.
Offer a variety of foods appropriate for your child's age, including vegetables, fruits, grains, pulses, dairy or suitable alternatives, and other nutritious foods.
For infants, follow age-appropriate feeding guidance from your healthcare professional.
4. Keep drinking water and food safe
Use safe drinking water and practise good food hygiene.
Wash fruits and vegetables properly and make sure food is cooked and stored safely.
5. Avoid tobacco smoke
Children should not be exposed to cigarette or other tobacco smoke.
Reducing exposure to indoor air pollution can also help lower the risk of respiratory illness.
6. Encourage enough sleep and physical activity
Children need adequate sleep for healthy growth and development.
As they grow, regular age-appropriate physical activity is also important.
7. Teach children not to share personal items
Encourage children not to share items such as water bottles, spoons, towels and toothbrushes, particularly when someone is unwell.
8. Keep sick children at home when appropriate
If your child has an infection that can easily spread, keeping them away from school or daycare until they are well enough to return can help protect other children.
Your child's doctor can advise you about when it is safe to return.
These habits may seem simple, but they can make a meaningful difference when practised consistently.
6. When Should You Take Your Child to a Doctor?
Most childhood illnesses are manageable, but parents should know when home care is no longer enough.
Do not wait if your child appears seriously unwell.
Seek prompt medical attention if your child:
- Has difficulty breathing.
- Is breathing unusually fast.
- Is unusually sleepy, difficult to wake or not responding normally.
- Has a seizure or convulsion.
- Is unable to drink or breastfeed.
- Is repeatedly vomiting and cannot keep fluids down.
- Has signs of significant dehydration.
- Has blood in the stool or vomit.
- Has a severe or rapidly worsening illness.
- Develops a concerning rash with fever or other serious symptoms.
- Has a fever that is concerning based on their age or medical condition.
- Has symptoms that are getting worse instead of better.
Young babies require particular attention. If a young infant is feeding poorly, has difficulty breathing, has a fever, feels unusually cold, becomes less active or develops other concerning symptoms, seek medical care promptly. These are among the warning signs highlighted in child-health guidance.
Most importantly, trust your instincts as a parent. You know how your child normally behaves. If your child suddenly seems very different or much more unwell than usual, it is better to get medical advice.
