Pneumonia recovery in infants
Informed by recognized medical guidance
Overview
Pneumonia is an infection in the lungs that causes the tiny air sacs to fill with fluid or pus. In infants, it can make breathing difficult and requires careful recovery.
Key facts
- Pneumonia is a common cause of serious illness in infants, but most recover fully with proper care.
- Recovery can take several weeks, and rest is very important.
- Vaccines and breastfeeding can help protect infants from pneumonia.
Pneumonia is one of the more common serious infections in infants, especially in the first two years of life.
It most often affects infants under two years old, particularly those with weaker immune systems or underlying health conditions.
Symptoms
- If your infant stops breathing, turns blue, or has severe trouble breathing (e.g., chest heaving, gasping)
- If they become unresponsive or very difficult to wake
- If you think they are choking or their airway is blocked
- ⚠If your infant has a cough that lasts more than a few days or gets worse
- ⚠If they have a fever that does not come down with age-appropriate fever relief methods
- ⚠If they are feeding very little or not at all, or showing signs of dehydration (fewer wet diapers, dry mouth)
- ⚠If they seem unusually sleepy or irritable
Common symptoms
- Cough
- Fever
- Fast or difficult breathing
- Poor feeding or not wanting to eat
- Unusual tiredness or fussiness
Symptoms in children
- In infants, symptoms may include grunting sounds when breathing, flaring nostrils, or pulling in of the chest between the ribs.
- They may also have a high fever or a drop in body temperature.
- Some infants may turn blue around the lips or nails, which is a sign of low oxygen.
Symptoms in older adults
- This article focuses on infant recovery, but in older adults pneumonia can cause confusion, weakness, or a lower than normal body temperature.
Causes
Main causes
- Bacteria: The most common cause in infants is a bacterium called Streptococcus pneumoniae.
- Viruses: Respiratory syncytial virus (RSV) and influenza (the flu) are common viral causes.
- Fungi: Less common, but can occur in infants with weakened immune systems.
Risk factors
- Premature birth or low birth weight
- Not being breastfed exclusively for the first six months
- Weak immune system due to illness or medications
- Exposure to cigarette smoke or air pollution
- Crowded living conditions
When to see a doctor
See a doctor urgently if:
- If your infant has any emergency symptoms listed above, call your local emergency number immediately.
- If your infant is under 3 months old and has a fever (any temperature above 38°C or 100.4°F), see a doctor urgently.
Book a routine appointment if:
- If your infant is recovering from pneumonia at home and you have concerns about their breathing, feeding, or energy levels, schedule a follow-up appointment with their pediatrician.
- If the cough persists longer than three weeks after starting treatment.
Diagnosis
A doctor will ask about symptoms, listen to your infant's lungs with a stethoscope, and may order tests to confirm pneumonia and find the cause.
Tests that may be done
- Chest X-ray: To see the infection in the lungs.
- Blood tests: To check for signs of infection and find the germ causing it.
- Oxygen saturation test: A small sensor taped to the foot or hand to measure oxygen levels in the blood.
- Sometimes a swab from the nose or throat to test for viruses.
What to expect at your appointment
The doctor will explain the test results and recommend a treatment plan. For infants, treatment often involves hospital care, especially if they have trouble breathing, are very young, or are not feeding well. You may be asked to stay in the hospital with your baby.
Treatment
Treatment focuses on fighting the infection, supporting breathing, and helping the infant rest and feed. Most infants are treated with antibiotics if bacteria are the cause, or supportive care if a virus is the cause. Hospital care is common for infants.
Self-care at home
- Give plenty of breast milk or formula to keep your baby hydrated. Small, frequent feeds may be easier.
- Make sure your infant gets lots of rest. Keep the environment calm and quiet.
- Use a cool-mist humidifier in the room or sit with your baby in a steamy bathroom for a few minutes to help loosen congestion.
- Follow the doctor's advice on fever management – never give aspirin to infants.
Medical treatments
Doctors may prescribe antibiotics if the infection is bacterial. These are usually given by injection or intravenously in the hospital. For viral pneumonia, antibiotics do not work; instead, doctors focus on supportive care such as oxygen therapy, fluids, and sometimes antiviral medications. In hospital, a baby might receive extra oxygen through a mask or tubes in the nose, and fluids through a vein if they cannot drink enough.
When is surgery considered?
Surgery is rarely needed for infant pneumonia. It may be considered if a collection of pus forms around the lung (empyema) and does not drain with a needle or tube, but this is very uncommon.
Living with this condition
During recovery, your infant will need extra rest and patience. Expect them to be more tired and possibly feed less at first. It is normal for a cough to linger for two to three weeks. Keep them away from smoke and other lung irritants.
Lifestyle tips
- Avoid exposure to cigarette smoke or any kind of smoke around your baby.
- Keep your baby away from large crowds or people with colds or flu until fully recovered.
- Wash your hands often before handling your baby to avoid passing other germs.
Diet and exercise
Breast milk or formula is the best source of hydration and nutrition. If your baby is older than six months, they may also have small amounts of water. Do not restrict activity; let your baby move and play when they feel up to it, but do not push them.
Mental health and emotional wellbeing
Caring for a sick infant can be very stressful for parents. It is normal to feel anxious or worried. Take breaks when you can, ask for help from family or friends, and talk to your doctor if you feel overwhelmed. If you have feelings of harming yourself or the baby, call your local emergency number or a crisis line immediately.
Prevention
Many cases of pneumonia can be prevented with good hygiene, breastfeeding, and avoiding smoke. Vaccines also play a big role in prevention.
Vaccines
Two important vaccines for infants are the pneumococcal conjugate vaccine (PCV) and the Hib vaccine. These are part of routine childhood immunizations in many countries, including the UK. Make sure your infant receives all recommended vaccines on schedule. Also, pregnant women can get the whooping cough (pertussis) vaccine and flu vaccine to help protect the newborn.
Screening programmes
There is no routine screening for pneumonia. However, infants at high risk (e.g., premature babies or those with chronic lung disease) may be monitored more closely by their doctor.
Complications
If left untreated
- Breathing failure requiring a breathing machine (ventilator)
- Infection spreading to the blood (sepsis) or to the covering of the brain (meningitis)
- A collection of pus around the lung (empyema) that may need draining
- Long-term lung damage in rare cases
Long-term outlook
With prompt medical care, the vast majority of infants recover fully from pneumonia without lasting problems. Recovery can take a few weeks, but most babies return to their normal selves. Early treatment gives the best chance for a good outcome.
