Pneumonia in children
Pneumonia in children (pneu·mo·nia) occurs when the lungs swell and fill with fluid due to an infection.
What is pneumonia in children?
Pediatric pneumonia is a general term for any lung infection. It typically begins when an infection affecting the upper respiratory system (nose, throat and airways) moves into the lungs, causing them to swell with fluid. Pneumonia can impact one or both lungs, and be located at the top or bottom of a child’s lung.
If left untreated, it can be extremely dangerous and lead to serious complications like respiratory failure (organs will not receive oxygen), sepsis or the infection can spread to other areas.
Risk factors
Infants (birth to 1 year) and toddlers (1 to 3 years) are at a higher risk of developing pneumonia, as they are still building their immune systems.
What are the different types of pneumonia in children?
There are four types of pneumonia:
- Bacterial pneumonia - streptococcus pneumonia or bacterial bronchitis
- Fungal pneumonia - pulmonary aspergilloma, invasive aspergillosis or allergic bronchopulmonary aspergillosis
- Parasitic pneumonia - ascariasis (a round worm), schistosoma (flatworms also known as blood flukes) and toxoplasma gondii (toxoplasmosis, typically associated with cats)
- Viral pneumonia - the flu or respiratory syncytial virus (RSV)
What are the signs and symptoms of pneumonia in children?
Children will experience pneumonia symptoms differently than adults — they may not have symptoms or they can be subtle. Signs will also vary with age and cause of the pneumonia.

Pediatric pneumonia can be caused by a bacteria, virus, fungus or parasites (in rare occasions). Bacteria and viruses are the main causes of pneumonia infections.
