Pneumonia in Children: Symptoms, Causes, Types, Diagnosis and Treatment

Almost every child in Pakistan gets a cough in winter. Almost none of them have pneumonia. But some do — and pneumonia remains the single largest infectious cause of death in children under five in this country, not because it is untreatable, but because it is so often recognised late.

That gap between “a bad cough” and “pneumonia” is the entire subject of this page, and there is a genuinely useful skill hidden inside it. The most reliable early sign of pneumonia in a child is not the cough, and not the fever. It is how fast they are breathing. Fever comes and goes. Cough is universal. But a child whose lungs are struggling breathes faster to compensate — and that change appears before the child looks seriously unwell.
Counting your child’s breaths takes sixty seconds and needs no equipment. It is the same first step a doctor uses, whether you are in Karachi, Lahore, Peshawar or Rawalpindi — and it is the reason many parents reach the child specialists in our pediatric medicine department at Kids Care International Hospital in time. This article will teach you that skill, then walk through what pneumonia is, why children get it, how it is diagnosed, how it is treated — and how much of it can simply be prevented.

What Is Pneumonia?

Deep inside the lungs, the airways end in millions of microscopic air sacs called alveoli. These are where the work happens: oxygen crosses from the air into the blood, and carbon dioxide crosses back out. Everything above them — the throat, windpipe and bronchi — is just plumbing.
Pneumonia is an infection that reaches those air sacs and fills them with fluid, pus and inflammatory cells. Sacs full of fluid cannot exchange gas. The child’s oxygen level starts to fall, and the body responds in the only way available to it: breathe faster, and work harder with each breath.
This is what separates pneumonia from the illnesses it is often confused with. A common cold is an infection of the nose and throat. Bronchitis and bronchiolitis inflame the airways. Pneumonia goes further down, into the tissue that does the actual breathing — which is why it makes children breathe fast, and why it can become dangerous when the illnesses above it usually do not.
Children are more vulnerable than adults for reasons of simple physics and biology: their airways are narrower, so a small amount of swelling blocks proportionally more; their chest muscles tire faster; and under-fives have immune systems still meeting most of these germs for the first time.

How to count breaths correctly

Wait until your child is calm — ideally asleep, or resting quietly. Crying, feeding, running or fever-spiking all raise the rate and will mislead you. Lift or open the shirt so you can see the chest and tummy. Watch one full rise-and-fall as one breath, and count for a full 60 seconds — not 15 seconds multiplied by four, because children’s breathing is naturally irregular.

What counts as too fast

These are the internationally used thresholds for fast breathing in a calm child:

Child’s age :

Fast breathing means

Under 2 months :

60 breaths per minute or more

2 to 11 months :

50 breaths per minute or more

1 to 5 years :

40 breaths per minute or more

Over 5 years :

Around 30 breaths per minute or more

The second thing to look for: chest indrawing

While the shirt is up, watch the lower chest as your child breathes in. Normally, the whole chest expands outward. In a child whose lungs are stiff with infection, the lower chest wall gets sucked inward with each breath instead — as though the skin is being pulled in under the ribs.

Chest indrawing means the child is not just breathing fast, but working hard to breathe. It is a sign of severe pneumonia and it means hospital, today — not tomorrow morning.

Also watch for grunting (a short sound at the end of each breath), nostrils flaring with each breath, and the head nodding with breathing in a small baby. All of these say the same thing: this child is struggling

What Causes Pneumonia in Children?

Pneumonia is caused by germs reaching the air sacs — most often germs the child breathed in from an infected person’s cough or sneeze, or that travelled down from a cold already in progress.

Viruses are the most common cause in young children, especially under five. Respiratory syncytial virus (RSV) leads the list, followed by influenza, parainfluenza, adenovirus, rhinovirus, measles and COVID-19. Viral pneumonia usually builds up gradually over days, following an ordinary cold.

Bacteria cause fewer cases but more of the severe ones. Streptococcus pneumoniae (pneumococcus) is the main culprit worldwide, along with Haemophilus influenzae type b (Hib) and Staphylococcus aureus. Bacterial pneumonia typically arrives faster and hits harder — high fever, a suddenly unwell child, sometimes chest or tummy pain.

Atypical bacteria such as Mycoplasma pneumoniae cause the milder, drawn-out illness often called “walking pneumonia” — more common in school-age children and teenagers, who keep going to school with a dry, nagging cough for weeks.

Aspiration is a separate route: milk, food, or vomit going down the wrong way into the lungs. This matters particularly for babies with swallowing difficulties, reflux, or neurological conditions.

Why some children get pneumonia and others don’t

The germ is only half the story. These factors raise a child’s risk considerably:

  • ♦ Age under 2, and especially under 6 months
  • ♦ Missed or incomplete vaccinations — the largest preventable factor of all
  • ♦ Malnutrition, low birth weight, and vitamin A or zinc deficiency, which blunt the immune response
  • ♦ Not being exclusively breastfed in the first six months
  • ♦ Indoor smoke — wood, coal, dung or crop-residue cooking and heating fires, and gas heaters in closed rooms
  • ♦ Household tobacco smoke. A child does not have to smoke to have their airways damaged by it; someone else smoking indoors is enough.
  • ♦ Crowded, poorly ventilated rooms, especially in winter when doors and windows stay shut
  • ♦ Outdoor air pollution and smog, which blankets Punjab and much of northern Pakistan from late autumn through winter — the same months pneumonia admissions rise
  • ♦ Existing conditions: asthma, congenital heart disease, prematurity, cerebral palsy, or any illness affecting immunity

Symptoms of Pneumonia in Children

Pneumonia rarely announces itself. It usually starts as an ordinary cold that fails to improve — or improves and then turns worse again.

Common symptoms:

  • ♦ Cough — dry at first, often becoming wet or productive
  • ♦ Fever, sometimes high, occasionally with shivering
  • ♦ Fast breathing (see the thresholds above)
  • ♦ Difficulty breathing; the child looks like breathing is taking effort
  • ♦ Chest pain, worse on coughing or deep breaths
  • ♦ Poor appetite; a baby feeding less or refusing the breast
  • ♦ Unusual tiredness, sleepiness or irritability
  • ♦ Vomiting, sometimes triggered by coughing bouts
  • ♦ Wheeze — more common with viral pneumonia
  •  

In newborns and small babies, pneumonia often looks completely different. Cough may be minimal or absent, and fever may not appear at all. Instead look for: poor feeding, unusual floppiness or lethargy, grunting, fast breathing, temperature instability (too low as well as too high), or bluish colour around the lips. A baby under two months with any of these needs to be seen immediately — young infants deteriorate quickly and quietly.

Warning signs that mean go to hospital now

Do not wait until morning if your child has any of the following:

  • ♦ Chest indrawing — the lower chest sucking inward with each breath
  • ♦ Blue or dusky colour of the lips, tongue or fingertips
  • ♦ Grunting with each breath, or head nodding in a baby
  • ♦ Unable to drink or breastfeed, or vomiting everything
  • ♦ Unusually drowsy, floppy, or difficult to wake
  • ♦ A convulsion (fit)
  • ♦ Any breathing difficulty in a baby under 2 months
  • ♦ A child with an existing heart or lung condition who develops a chest infection

KCIH’s emergency department operates around the clock, with PICU care available for children who need oxygen and close monitoring.

Types of Pneumonia in Children

Doctors classify pneumonia in several ways, and the terms you may hear on a report mean different things:

By causeViral pneumonia — commonest in under-fives, gradual onset, often with wheeze; antibiotics do not help it – Bacterial pneumonia — fewer cases but more severe, faster onset, high fever; needs antibiotics – Atypical (“walking”) pneumonia — mild but persistent, dry cough over weeks, mostly in older children – Aspiration pneumonia — from food, milk or vomit entering the lungs

By how much lung is involvedLobar pneumonia — one whole section (lobe) of a lung is affected; typical of pneumococcal infection – Bronchopneumonia — patchy areas scattered through both lungs; common in infants – Interstitial pneumonia — inflammation of the tissue between the air sacs rather than the sacs themselves; typical of viral infection

By where it was caughtCommunity-acquired pneumonia — the ordinary kind, caught in daily life; the vast majority of childhood cases – Hospital-acquired pneumonia — developing during an admission for something else; less common but often caused by more resistant bacteria

By severity — the classification that actually drives treatment: – Pneumonia — fast breathing, but the child is alert, drinking, and has no indrawing. Usually treatable at home with oral antibiotics. – Severe pneumonia — chest indrawing, or any danger sign. Needs hospital admission, oxygen and injectable treatment.

If your child has already been recommended surgery, you can ask for a consultation to discuss a minimally invasive option.

How Is Pneumonia Diagnosed?

Parents often expect an X-ray to be the deciding test. In reality, most childhood pneumonia is diagnosed at the bedside, and a good clinical examination outperforms any single investigation.

The examination. The doctor counts the breathing rate, watches for indrawing and effort, checks oxygen saturation with a pulse oximeter on the finger or toe, and listens to the chest with a stethoscope for crackles, reduced air entry, or bronchial breathing over the affected area. Together these usually establish both the diagnosis and the severity.

Chest X-ray. Useful when the diagnosis is uncertain, the child is severely ill, isn’t improving on treatment, or a complication such as fluid around the lung is suspected. It is not needed for every child with pneumonia, and a normal X-ray early in the illness does not always exclude it.

Blood tests. A full blood count and inflammatory markers (CRP) help judge severity and can support — though never prove — a bacterial cause. Blood cultures may be taken in seriously ill children.

Oxygen saturation is arguably the most important number in the room. It is quick, painless and directly measures what the illness is actually doing to the child.

Other tests in selected cases: viral swabs from the nose (RSV, influenza, COVID-19), sputum tests in older children, tests for tuberculosis where the cough has lasted weeks or there is weight loss or a household TB contact, and an ultrasound of the chest when fluid is suspected.

All of these are available at KCIH’s on-site diagnostic facility, so a child can be examined, tested and started on treatment in one visit rather than being sent between buildings.

How Is Pneumonia in Children Treated?

Treatment follows severity, not the label. Most children are treated at home; a minority need admission.

At home — mild pneumonia

  • Antibiotics if a bacterial cause is likely.Complete the full course. 
  • ♦ Frequent small drinks, and continued breastfeeding for babies. 
  • ♦ Fever and comfort. Paracetamol at the correct weight-based dose. 
  • ♦ Rest, and a smoke-free, well-ventilated room.

What does not help: over-the-counter cough syrups and cough suppressants are not recommended for young children — coughing is how the lungs clear themselves. Antibiotics leftover from a previous illness, or bought without prescription, are actively harmful

In hospital — severe pneumonia

Children are admitted when they have chest indrawing, low oxygen saturation, are too unwell to drink, are under two months of age, or are not responding to oral treatment. Hospital care includes:

  • ♦ Oxygen, by nasal prongs or mask — the single most important treatment in severe pneumonia
  • ♦ Injectable antibiotics, switched to oral once the child improves
  • ♦ Intravenous fluids if drinking isn’t possible
  • ♦ Monitoring of oxygen saturation, breathing rate and feeding
  • ♦ PICU care with advanced respiratory support for the small number of children who need it
  • ♦ Drainage if infected fluid collects around the lung (empyema)

 

How long recovery takes

Fever usually settles within two to three days of starting the right treatment, and energy returns over the following week. The cough is the last thing to go, and it can persist for four to six weeks in a child who has otherwise fully recovered. 

Can Pneumonia Be Prevented?

More than most parents expect. Pneumonia is one of the few major childhood illnesses where prevention genuinely works.

Vaccination is the strongest protection available. Several vaccines in Pakistan’s routine EPI schedule directly prevent the germs that cause the worst pneumonia:

  • ♦ Pneumococcal conjugate vaccine (PCV) — given at 6, 10 and 14 weeks; protects against the leading bacterial cause
  • ♦ Pentavalent vaccine, which includes Hib — same schedule; prevents another major bacterial cause
  • ♦ Measles vaccine at 9 and 15 months — measles frequently leads to pneumonia
  • ♦ Whooping cough (pertussis) protection, also in the pentavalent vaccine
  • ♦ Annual influenza vaccine, available privately, worth considering for children with asthma, heart disease, or other chronic conditions

Vaccination is free at government EPI centres and available at KCIH. If your child’s schedule has been interrupted, it can be caught up — ask rather than assume it is too late.

Beyond vaccines:

  • ♦ Exclusive breastfeeding for the first six months, and continued breastfeeding afterwards — this measurably reduces pneumonia risk
  • ♦ Good nutrition, with adequate vitamin A and zinc
  • ♦ Handwashing with soap, especially before feeding a baby 
  • ♦ A smoke-free home. No smoking indoors, ever. Ventilate rooms where heaters or cooking fires are used, and avoid gas heaters running in closed 
  • Keep small babies away from adults with active coughs and colds
  • ♦ On heavy smog days, keep young children indoors during peak pollution hours

When to See a Child Specialist

Wherever in Pakistan you are reading this, the rule is the same: have your child seen if a cough and fever have lasted more than three days without improvement, if breathing looks fast or laboured, if feeding has dropped off, or if your instinct says something is different about this illness. Go immediately — at any hour — for chest indrawing, blue lips, grunting, drowsiness, inability to drink, or any breathing difficulty in a baby under two months.

If you are in Rawalpindi, Islamabad or the surrounding districts, children with pneumonia are assessed at Kids Care International Hospital by our child specialist Dr. Samer Sikander in the pediatric medicine department, with on-site X-ray and laboratory, oxygen and inpatient care, PICU support for severe cases, NICU care for newborns, and vaccination services to prevent the next episode — all under one roof, in a hospital that treats only children and mothers.

Frequently Asked Questions by Parents

How do I know if my child has pneumonia or just a cold or chest infection?

A cold stays in the nose and throat: the child coughs but breathes normally and plays. Pneumonia reaches the air sacs deep in the lungs, so the child breathes faster than normal, tires easily, feeds less, and often has ongoing fever. The most reliable home check is counting breaths for a full minute while your child is calm — fast breathing is the earliest dependable warning sign.

Count for a full 60 seconds while your child is calm or asleep. Breathing is too fast at 60 or more breaths per minute under 2 months of age, 50 or more from 2 to 11 months, 40 or more from 1 to 5 years, and around 30 or more above 5 years. Crying, feeding or a high fever will raise the count, so re-check when your child settles.

No. Most pneumonia in young children is caused by viruses, and antibiotics have no effect on viruses. Doctors judge from the pattern of illness, examination findings and, where needed, tests whether a bacterial cause is likely. Never start leftover or over-the-counter antibiotics yourself — the wrong drug delays proper treatment and contributes to antibiotic resistance.

Usually not. Most childhood pneumonia is diagnosed by examination — breathing rate, chest indrawing, oxygen saturation and listening to the chest. An X-ray is reserved for uncertain cases, severely ill children, those not improving on treatment, or where a complication such as fluid around the lung is suspected. Your doctor will advise if one is needed.

Fever typically settles within two to three days of correct treatment, and energy returns over the following week. The cough is the last symptom to go and can linger for four to six weeks even after complete recovery. A steadily fading cough in a child who is active, eating and breathing normally is expected — a worsening cough or returning fever is not, and should be reviewed.

No — finish the entire prescribed course. Children usually look much better after two to three days, which is exactly when families stop the syrup, and it is a leading cause of relapse and of antibiotic resistance. Bacteria surviving a half-finished course are the hardest ones to kill next time. Stop only when the course is complete or your doctor advises it.

The pneumococcal conjugate vaccine (PCV) and the pentavalent vaccine containing Hib — both given at 6, 10 and 14 weeks — protect against the leading bacterial causes. Measles vaccine at 9 and 15 months matters too, since measles commonly leads to pneumonia. An annual influenza vaccine is worth discussing for children with asthma, heart disease or other chronic conditions.

Rarely. The great majority of children who are treated in time recover completely, with lungs that work exactly as they did before. Lasting effects are associated with severe, repeated, or badly delayed infections — which is precisely the argument for seeking care while the child is breathing fast rather than waiting until they are struggling.

No, and they are not recommended for young children. Coughing is how the lungs clear fluid and mucus, so suppressing it is counterproductive, and several cough preparations carry real risks for small children. Fluids, rest, prescribed antibiotics where appropriate, and correctly dosed paracetamol for fever are what actually help.
