Pneumonia is normally confused with a minor complication of the flu, but it is much more severe than expected. The Department of Statistics Malaysia (DOSM) has revealed that pneumonia caused 18,181 deaths in 2024, corresponding to 15.2% of all medically certified fatalities. Despite these numbers, pneumonia is still not given enough credit when it comes to public health awareness.

Pneumonia, an infection causing the inflammation of air sacs in one or both lungs, leads them to fill with fluid or pus (Mayo Clinic, 2020). This causes coughing, fever, chills, chest pain, and breathing difficulties. Streptococcus pneumoniae, the main cause of pneumococcal pneumonia, is among the deadliest culprits.
