Pneumonia in Children: Causes, Signs, and Treatment

Approved By: Dr. Sampat Kumar Shettigar August 11, 2025 | 04:27 pm

Although worldwide cases of pneumonia in children have significantly decreased over the years, it continues to be one of the most rampant illnesses in India. Understanding pneumonia-its causes, early diagnosis, and treatment can help parents and pediatric hospitals better manage child health and improve the nation’s health index.

So, what is pneumonia in children?

Pneumonia is typically a lung infection. A virus, fungus, or bacterium can cause the air sacs in your child’s lungs to fill with mucus, along with the swelling or inflammation of lung tissues. This makes it difficult for your child to breathe and causes a chronic and also persistent cough, usually accompanied by a fever.

Pneumonia causes

As mentioned, a virus, bacteria, or a fungus can cause pneumonia. The most common causes of pneumonia are:

  • Streptococcus pneumoniae bacteria
  • Haemophilus influenzae type b Bacteria
  • Respiratory syncytial virus
  • Fungi like Cryptococcus and Jirovecii can also cause pneumonia. However, children with an underlying medical condition or a compromised immune system are more likely to contract pneumonia from a fungus.

Types of Pneumonia in Children

Doctors classify pneumonia in children in different ways to help choose the best treatment. Here are the main types based on what causes the infection and how the child is affected:

1. Viral Pneumonia

This is the most common form in young children. It’s caused by viruses like:

  • Respiratory Syncytial Virus (RSV)
  • Influenza
  • Adenovirus
  • Parainfluenza virus
  • COVID-19 (SARS-CoV-2)

Children may have symptoms like cough, mild fever, wheezing, and runny nose. Most cases improve with home care, rest, fluids, and fever medication without antibiotics.

2. Bacterial Pneumonia

This type is usually more severe and comes on quickly with:

  • High fever
  • Rapid breathing
  • Chest pain
  • Productive cough
  • Common bacteria include:
  • Streptococcus pneumoniae (most common)
  • Haemophilus influenzae
  • Staphylococcus aureus

This type usually requires antibiotics and close monitoring.

3. Atypical Pneumonia

Often seen in older children and teens, atypical pneumonia is milder but longer-lasting. It is caused by organisms like:

  • Mycoplasma pneumoniae
  • Chlamydophila pneumoniae

Symptoms may include:

  • Dry cough
  • Sore throat
  • Fatigue
  • Low-grade fever

This type is sometimes called “walking pneumonia” because children may still be active despite being unwell.

4. Aspiration Pneumonia

This occurs when food, liquid, or vomit accidentally enters the lungs, often in children who:

  • Have swallowing difficulties
  • Are neurologically impaired
  • Have severe reflux

It can lead to lung irritation and infection. Treatment may include antibiotics and addressing the underlying cause of aspiration.

5. Recurrent or Chronic Pneumonia

Children with weakened immunity, cystic fibrosis, or structural lung issues may have repeated or long-lasting pneumonia. These cases often need:

  • Further testing
  • Hospital care
  • Pediatric pulmonologist opinion

Signs of pneumonia in infants are difficult to diagnose. It is possible to confuse pneumonia symptoms with the clinical features of flu or also a cold. Therefore, prompt evaluation by a healthcare professional ensures proper diagnosis and treatment, reducing the risk of complications.

Pneumonia treatment options

Pneumonia treatment for children depends on the type of pneumonia. For example, you can treat bacteria causing pneumonia with antibiotics, while children diagnosed with viral pneumonia usually recover within a few days on their own without antibiotics.

Preventing pneumonia in children

As a parent, protecting your child against diseases is always a top priority. A combination of healthy habits, a nutritional diet plan, and also vaccinations can go a long way in protecting your child from pneumonia.

The Pneumococcal Conjugate Vaccine (PCV vaccine)given to newborns and also young children in India, as part of the Universal Immunization Program, considerably helps to protect children from pneumonia and also other pneumococcal diseases.
