Pneumonia is one of the top five causes of childhood death in Malaysia, according to the Department of Statistics.
What makes this infectious disease so deadly to children?
Pneumonia is a lung infection that causes the air sacs (alveoli) in the lungs to fill up with fluid or pus, making it difficult to breathe in enough oxygen for the body.
Anyone can get infected, but infants, the aged and sick people are the most vulnerable due to their weaker immune systems.
Globally, around 1.4 million children under five years of age die every year because of pneumonia.
Unicef has also reported that few caregivers recognise the symptoms of pneumonia and only half of infected children are given the appropriate treatment.
As the symptoms are similar to the common cold or flu, many parents may not realise the severity of their child’s condition until it is too late.
Types of pneumonia
Doctors may categorise pneumonia into how or where the infection started, i.e.:
- Hospital-acquired pneumonia, which occurs during a stay in a hospital or when receiving outpatient treatment.
The illness can be more severe as the infectious bacteria may be resistant to antibiotics.
- Community-acquired pneumonia, which starts somewhere other than a hospital or healthcare facility, and is more common.
This type of pneumonia can be caused by bacteria, viruses, fungi or chemicals.
Pneumonia can also be categorised based on the cause of the infection:
Streptococcus pneumoniae (pneumococcus) is the most common cause of bacterial pneumonia.
It is also the top source of pneumonia-linked deaths in children.
Other bacteria include Haemophilus influenzae type B (Hib), Klebsiella pneumoniae, Chlamydia pneumoniae and others.
Respiratory syncytial virus (RSV) is the most common cause of viral pneumonia in children.
Other viruses include the influenza virus (types A and B), rhinovirus (common cold virus), and coronavirus (like SARS-CoV and SARS-CoV-2).
Pneumocystis jirovecii is an example of a fungi that can cause fungal pneumonia.
However, this is less common and tends to happen to people with chronic health problems or weakened immune systems.
Different substances in different forms (liquid, gas, small particles) can cause inflammation of the lungs when inhaled.
This includes toxic and poisonous chemicals, as well as food and drinks (aspiration pneumonia).
Is it or is it not?
It can be hard to recognise the symptoms of pneumonia in children.
The symptoms not only range from mild to severe, but they also depend on the cause and health status of your child.
They may include:
- Rapid breathing
- Trouble breathing
- Skin, lips or fingertips that look blue
Treatment and prevention
Prompt and correct symptom identification is crucial to ensure early and appropriate care, which is vital for pneumonia.
If uncertain, it is best to seek doctors’ advice early on to be sure, rather than waiting for your child’s condition to worsen.
If treatment is delayed, complications may arise, such as:
This is where the infection spreads into the bloodstream, leading to septic shock and blood pressure dropping to a dangerous level.
Pockets of pus may build up in the lungs.
The child may also cough out pus and have a high fever.
The pleura (the two layers of tissue enveloping the lungs) become swollen and cause a sharp chest pain when breathing deeply.
If the swelling is untreated, fluid may fill the area between the pleura, causing pleural effusion (“water” around the lungs) and empyema (pus collection).
The lungs may be unable to function properly enough to transfer oxygen and remove carbon dioxide to and from the blood.
This can be life-threatening as organs such as the kidneys and heart, may also fail to function as normal.
Protection against pneumonia includes practising proper hygiene and handwashing, providing optimal nutrition, avoiding indoor pollution and smoking, and reducing other risk factors.
Immunisation against pneumococcus, influenza, Hib, measles and pertussis (whooping cough) is also vital.
Vaccines for Hib, measles and pertussis are part of our National Immunisation Programme (NIP), and the pneumococcal vaccine will soon be included in the NIP as well.
The annual influenza vaccine is available in both public and private healthcare facilities.
For pneumonia, early treatment is crucial for a higher survival rate.
In any case, it is always best to take protective and preventive measures.
