Can children get pleurisy and pneumonia and how do symptoms differ? 

Children of any age can develop pneumonia and its common complication, pleurisy. While both conditions involve inflammation in the respiratory system, pneumonia is an infection of the lung tissue itself, whereas pleurisy is the inflammation of the membranes surrounding the lungs. In children, these conditions can present differently than in adults, often involving non-respiratory symptoms like abdominal pain or extreme irritability, which requires careful observation by parents and caregivers.

Pneumonia in children 

Pneumonia is a common cause of hospital admission for children in the UK, particularly during the autumn and winter months. It is an infection that causes the tiny air sacs in the lungs to fill with fluid or pus, making it difficult for the child to breathe and for oxygen to enter the bloodstream. 

In babies and very young children, pneumonia is frequently caused by viruses, such as Respiratory Syncytial Virus (RSV), though bacterial causes like Streptococcus pneumoniae are also significant. Pneumonia is an acute infection of the lungs and children usually recover quickly with treatment. Because their airways are smaller and their immune systems are still developing, children with pneumonia may become unwell more rapidly than adults, often appearing very tired and listless. 

Recognizing pleurisy in a child 

Pleurisy in children most commonly occurs as a direct complication of pneumonia. When the infection in the lung tissue spreads to the pleural lining, the two layers of tissue rub together, causing sharp, localized pain. 

Identifying pleurisy in younger children can be challenging because they may not be able to describe the “stabbing” sensation. Instead, a child might cry when taking a deep breath, avoid moving their upper body, or breathe with very shallow, rapid gasps to minimize the pain. If you notice your child flinching or whimpering specifically when they cough or sneeze, this may indicate that the pleural lining is inflamed. 

How symptoms differ: Children vs. Adults 

While adults typically experience a productive cough and clear chest pain, children often display “atypical” symptoms. One notable difference is referred pain; a child with pneumonia in the lower part of their lungs may complain of a stomach ache rather than chest pain. 

Additionally, younger children and babies may show “grunting” sounds as they exhale or “nasal flaring,” where their nostrils widen with every breath. These are signs of respiratory distress that are more prominent in pediatric cases. Adults are more likely to experience confusion or a significant drop in blood pressure, whereas children are more likely to become inconsolable or refuse to feed. 

Symptom	Presentation in Children	Presentation in Adults
Pain Location	Often referred to the abdomen or neck	Mostly localized to the chest/back
Breathing Pattern	Grunting, nasal flaring, head bobbing	Shortness of breath, gasping
Behavior	Extreme irritability or floppiness	Confusion or disorientation
Feeding/Appetite	Refusal to breastfeed or drink	Reduced appetite
Onset	Can be very sudden in infants	Often gradual following a cold

Identifying respiratory distress 

It is crucial for parents to recognize the physical signs of “increased work of breathing.” In children, this often manifests as “chest recession” or “drawing in,” where the skin between the ribs or at the base of the throat sucks inward with every breath. 

This happens because the child is using extra muscles to try and pull air into their inflamed lungs. If a child is working this hard to breathe, they may become too exhausted to eat or drink, leading to dehydration. Bacterial pneumonia should be considered in children when there is persistent or repetitive fever together with chest recession and a raised respiratory rate. These physical signs are often more reliable indicators of severity in children than a cough alone. 

Diagnosis and UK treatment standards 

In the UK, GPs and hospital doctors diagnose pneumonia in children primarily through a physical examination and by listening to the chest for “crackling” sounds with a stethoscope. The course of treatment depends on the severity and age of the child. NICE guidance suggests that a three-day course of antibiotics is now considered effective for babies and children with non-severe community-acquired pneumonia. 

Chest X-rays are not routinely performed for children unless they are seriously unwell or if the doctor suspects a complication like a pleural effusion (fluid buildup) or empyema (pus). Treatment focuses on clearing the infection, managing pain with paracetamol or ibuprofen, and ensuring the child stays hydrated. Most children begin to improve within 48 to 72 hours of starting treatment, though a cough may linger for several weeks. 

Conclusion 

Both pneumonia and pleurisy are serious conditions in children that require prompt medical evaluation. While the symptoms like abdominal pain and grunting differ from the typical adult presentation, the underlying need for respiratory support and infection control remains the same. Early intervention with appropriate antibiotics and monitoring for signs of respiratory distress ensures that most children make a full recovery without long-term lung damage. 

If you experience severe, sudden, or worsening symptoms, call 999 immediately.
