Recurrent infections, coughs and colds in children (Assessment of recurrent infections in childhood)
An assessment to work out whether a child who seems to catch one cough or cold after another has a normal, busy immune system that is still learning — which is usually the case — or, rarely, a problem that needs investigating.

In short
- Catching around five to eight (or more) coughs and colds a year is normal for young children, especially at nursery or school, and most who seem 'always ill' have a normal immune system.
- The assessment cannot stop colds — it sorts the usual busy pattern from the rare signs that need investigating, and gives you a plan.
- Most children grow out of frequent infections as their immune system matures; investigations are only needed for specific warning signs.
- Warning signs that deserve review include faltering growth, unusually severe or prolonged infections, unusual germs, or a family history of immune problems.
A plain-English summary. The detail — including risks and recovery — is below.

What does it mean if my child keeps getting infections?
Young children catch a lot of coughs and colds — on average around five to eight a year, and sometimes more, especially once they start nursery or school. Each cold is caused by a different virus, and there are hundreds of them. Because young children have not yet met most of these viruses, their immune system is busy learning, and infections can run one straight into the next, particularly through winter.
This is normal. The great majority of children who seem to be 'always ill' have a completely normal immune system that is simply doing its job, and they grow out of it as they get older. Mixing with other children, older siblings, nursery, smoke exposure and the time of year all make infections more frequent without anything being wrong.
An assessment is about telling apart this normal pattern from the much rarer situation where infections are unusually frequent, severe, prolonged or caused by unusual germs — which can occasionally point to an underlying problem with the immune system, the chest, or another cause. The aim is to reassure where reassurance is right, and to investigate only when there is a genuine reason.
This assessment cannot promise your child will stop catching colds. What it can do is check growth and development, look for any pattern that needs attention, and give you a clear plan and the warning signs to watch for.
Types, options & approaches
There may be different ways to do this. The right approach depends on the clinical question and your circumstances.
Options at a glance
These are the main approaches described in this guide. The right option depends on the diagnosis, your goals and what your clinician thinks is safe.
History and reassurance
The clinician asks about how many infections, how severe, how long they last, growth, feeding, nursery or school, smoke exposure and family history. For most children this is...
Examination and growth check
Checking your child's growth on a chart, listening to the chest, and looking for signs of any underlying problem. Good growth and development is very reassuring.
Targeted tests (only if needed)
If there are warning signs, blood tests can check the immune system (such as antibody levels and how the body responds to vaccines) and a full blood count. These are not...
Chest-focused assessment
If coughs are mainly chesty, recurrent or with wheeze, the focus may shift to asthma, viral wheeze or, rarely, other lung causes, which have their own assessment and...
Preparing for your test
- Keep a simple diary: how many infections, how long each lasts, how unwell your child was, and any time off nursery or school.
- Bring your child's red book (personal child health record) with growth and immunisation details.
- Note any infections that needed antibiotics, hospital visits, or were caused by unusual germs.
- Think about the home and family picture: nursery, older siblings, smoking in the household, and any relatives with immune problems.
- List current symptoms, medicines and any allergies.
- Write down your main worry, so the clinician can answer the question that is on your mind.
What happens
The appointment usually starts with a careful history — how often your child is ill, how severe and how long each illness lasts, how they are growing and developing, and what their daily life looks like. Often this conversation alone makes clear that the pattern is normal.
The clinician will examine your child, check their growth on a chart and listen to their chest. Normal growth, normal development and a child who bounces back fully between infections are all strongly reassuring.
Most children need no tests. If there are warning signs, the clinician may arrange blood tests or a chest assessment, or refer to a paediatrician. You should leave with a clear explanation of whether this is the usual busy pattern or something that needs a closer look, and what to watch for.
Is this test right for me?
A good consultation should explore whether it's the right choice for you now — including reasons to wait or consider something else.
May not be suitable if…
- An acutely unwell child who needs urgent assessment now rather than a planned 'recurrent infections' review.
- A child whose main problem is wheeze or a chesty cough, who may need an asthma or chest assessment instead.
- Families seeking a test or supplement to stop normal colds, which no assessment can deliver.
- A child whose symptoms are clearly an allergy (such as hay fever) rather than repeated infections.
Delay or rearrange if…
- Your child is currently very unwell — seek urgent care first rather than booking a routine review.
- Immunisations are incomplete — completing them may be the most useful first step.
- You have not yet gathered the infection history, which is what makes the assessment useful.
- A recent infection is still settling, so growth and baseline health are hard to judge.
Alternatives to discuss
- Watchful waiting with an infection diary if there are no warning signs.
- Ensuring immunisations are up to date and reducing smoke exposure.
- A focused asthma or allergy assessment if the picture fits those better.
- A GP review before any private specialist appointment.
- Health visitor support and reassurance for very young children.
Before you decide
Use this as a shared-decision checklist. The aim is not just “can this be done?”, but whether it is right for you, now, with the risks and alternatives clearly understood.
What matters most to me?
Think about symptoms, daily life, work, caring responsibilities, sport, fertility, travel, appearance and anxiety — the right choice depends on your priorities, not just the medical facts.
What are all my options?
Ask about waiting, monitoring, medicines, rehabilitation, a smaller or larger procedure, a different test, NHS referral, or a second opinion where that would help.
What would make me pause?
Active infection, pregnancy, unstable medical problems, smoking, medicines that increase bleeding, poor support at home, or feeling pressured are all reasons to slow down and get tailored advice.
What happens if I do nothing today?
For some problems, waiting is safe; for others, delay can make treatment harder. A good consultation should explain the trade-off in plain English.
Benefits
- Reassurance, for most families, that the immune system is normal and the child will grow out of it
- A growth and development check that picks up any concern early
- A clear plan and the specific warning signs to watch for
- Sensible advice on reducing infections and supporting recovery
- Investigation reserved for the small number of children who genuinely need it
Risks & complications
- The appointment may simply confirm a normal pattern, which can feel unsatisfying if you hoped for a 'fix'
- It cannot stop your child catching colds
- Worry while waiting for any test results
- A blood test involves a brief needle, which children find uncomfortable
- Tests that show a minor or temporary finding needing repeat testing, causing extra anxiety
- Incidental findings that lead to further tests
- Reassurance that turns out to need revisiting if the pattern changes
- An underlying problem (such as an immune deficiency, a chest condition or another cause) being found, which then needs specialist care
- Missing a rare diagnosis if warning signs are not recognised — which is why the warning signs matter
The main risk is over-investigation: testing a normal, busy child can cause worry and lead to more tests without changing anything. The opposite risk is under-recognising the small number of children with genuine red flags. A good assessment balances these — reassuring most families confidently while keeping a clear eye on growth, severity and the warning signs.
Published figures to discuss
There is no single reliable figure for how often recurrent infections turn out to be an immune problem, because it depends heavily on the child, their age and the specific pattern. What is clear from UK sources is that frequent coughs and colds are common and usually normal, and that significant immune deficiencies are rare. We therefore use qualitative wording rather than inventing percentages.
| Figure | Reported range | How to interpret it | Source / confidence |
|---|---|---|---|
| Frequent viral infections | Common in nursery and early school years | Repeated colds alone are usually not immune deficiency, especially if the child grows well and recovers normally. | NHS — Colds, coughs and ear infections in childrennhs.ukSource-linked context |
| Asthma, allergy or environmental trigger missed | Common contributor | Night cough, wheeze, eczema, hay fever, smoke exposure and damp housing should be considered. | Guide sourcesClinical context |
| Immune deficiency red flags | Uncommon but important | Severe, unusual, persistent or invasive infections, poor growth, chronic diarrhoea or needing IV antibiotics should prompt specialist review. | NHS — Colds, coughs and ear infections in childrennhs.ukSource-linked context |
| Unnecessary antibiotics | Common practical risk | Most colds are viral; repeated antibiotics can cause side effects and resistance without helping. | NHS — Colds, coughs and ear infections in childrennhs.ukSource-linked context |
These are literature figures, not a personalised prediction. Your own risks and likely benefits depend on your circumstances, your health, and how your care is carried out and followed up.
What happens afterwards
There is no physical recovery from this assessment. 'Afterwards' is about understanding what the pattern means, following any advice, and knowing when to come back.
- No immediate change — your child will still catch the colds that are going around
- Fewer infections over time as the immune system matures
- Full recovery between infections, with normal energy and growth
- Reassurance now, with a plan to review only if things change
Aftercare
- Follow any advice on reducing infection spread, such as handwashing and avoiding smoke exposure.
- Keep your child's immunisations up to date, as these protect against serious infections.
- Support recovery between colds with fluids, rest and simple measures for fever or discomfort.
- Keep your infection diary going if you were asked to, so any change is easy to spot.
- Attend for any blood tests or follow-up that were arranged.
- Know the warning signs and who to contact if they appear.
- Infection diary up to date
- Red book with growth and immunisation records
- List of infections that needed antibiotics or hospital care
- Family history of immune problems noted
- Immunisations up to date
- Clear note of warning signs and who to contact
- Any blood test appointment booked

Results & realistic expectations
For most children, the 'result' is reassurance: a normal examination, normal growth and a pattern of ordinary viral infections that they will grow out of. That is a genuinely good outcome, even though it does not make the colds stop.
Where tests are done, normal immune blood tests and good growth are very reassuring. A normal assessment does not guarantee your child will never have a serious infection, so the warning signs still matter. If tests show a problem, your child will be referred for the right specialist care.
Frequent infections in early childhood usually settle as the immune system matures, often noticeably after the first year or two of nursery or school. Reassurance from a normal assessment holds as long as the pattern stays the same; if infections become more frequent, severe or prolonged, or growth falters, the situation should be reviewed again.
Related tests, treatments or support
Recurrent coughs are sometimes part of asthma or viral wheeze rather than separate infections, and recurrent ear or chest symptoms may need their own assessment. Allergies such as hay fever can also cause a runny nose that is mistaken for endless colds. Mention all of these so the right thing is assessed.
Follow-up & long-term care
Most children need no formal follow-up beyond the advice to return if things change. If tests or a referral were arranged, results are explained and a plan made. A paediatrician or, rarely, an immunologist reviews children with genuine red flags.
- Keep immunisations up to date.
- Reduce avoidable triggers such as smoke exposure in the home or car.
- Watch growth and the warning signs, and return if the pattern changes.
- Review again if infections become more frequent, severe or prolonged over time.
Repeat, follow-on and what comes next
- Reassurance may need revisiting if the pattern of infections changes or growth falters.
- Some blood tests are borderline or temporary and need repeating before anything is concluded.
- A few children are referred onward for more detailed assessment after an initial review.
Ask what happens if the result is unclear or needs repeating, and what is included if further tests or follow-up are needed.
What good aftercare looks like
- A clear explanation of whether this is the normal busy pattern or needs investigation.
- Written warning signs and a named route back for advice if things change.
- Any test results explained, with a plan rather than a list of numbers.
- Joined-up referral if a chest, allergy or immune assessment is genuinely needed.
What affects the cost
Costs vary a great deal between people and providers, and we don't publish prices. What matters is understanding what drives the cost and making sure your quote is complete. The main things that affect it:
- Whether it is a single consultation or includes follow-up
- The length and seniority of the appointment (GP versus paediatrician)
- Whether blood tests or other investigations are arranged
- Whether a chest or allergy assessment is added
- Whether referral to a paediatric specialist or immunologist is needed
- Any repeat tests if early results are borderline
- The consultation fee and how long the appointment lasts
- Whether any tests are included and what they cost
- Whether results are explained in a follow-up and whether that is included
- What happens, and what it costs, if results are inconclusive or repeat tests are needed
- Whether onward referral would be NHS or private
- Who to contact if your child becomes unwell after the appointment
On the NHS? Recurrent infections are usually assessed by a GP on the NHS, with referral to a paediatrician if needed; private paediatric appointments may be used for reassurance, a second opinion or a quicker review.
You're entitled to your total cost in writing — including reports, follow-up and what happens if the result is inconclusive — before you decide.
Consent traps and marketing red flags
These are not small details. They are often where patients lose choice, time to reflect, or realistic expectations.
Consent traps
- Ordering broad blood-test panels in a well, thriving child without a clear reason.
- Giving blanket reassurance without checking growth or the warning signs.
- Selling supplements or 'immune boosters' that do not prevent ordinary viral infections.
- Not explaining that a normal result does not guarantee no future serious infection.
Marketing red flags
- Clinics offering routine 'immune system MOTs' for healthy children who simply catch colds.
- Unproven tests such as IgG food-intolerance or hair-mineral analysis to explain infections.
- Promises to stop a child catching colds.
- Supplements or drips marketed as boosting a child's immunity.
Choosing a specialist safely
- Check the specialist is on the GMC Specialist Register for this area.
- Make sure they work at a CQC-registered service, and look for membership of the relevant Royal College or professional body.
- You're entitled to time to consider and to have your questions answered before you agree — the specialist who looks after you should explain it, not a salesperson.
- Be wary of pressure: time-limited offers or deposits taken before you've had time to think are red flags, not bargains.
- You're entitled to your total cost in writing — including any follow-up — before you decide.
Questions to ask your medical professional
Take this to your consultation. A good specialist will welcome every one of these.
- Is my child's pattern of infections normal for their age?
- Is their growth and development on track?
- Are there any warning signs in their history that concern you?
- Do they need any tests, and what would the results change?
- Could the coughs be asthma or the runny nose be an allergy?
- What exactly should I watch for, and when should I bring them back?
- Are you on the GMC Specialist Register for this area, and which Royal College or professional body are you a member of?
- Will you be the specialist who carries out my test, and who looks after me afterwards?
- What are the risks for someone like me, and how often do your own patients have a problem or need it repeated or redone?
- What does a realistic result look like — and what can this test not achieve?
- What are my options, including waiting, doing nothing for now, or choosing a different approach?
- Can I have written information, results and aftercare instructions in a format I can use, including any accessibility or communication support I need?
- What is the total cost in writing, including any follow-ups, and how much time do I have to decide?
