While most people recover within a week or two, there could be some who may experience complications, including pneumonia. The interplay between flu and pneumonia is quite concerning to those vulnerable groups of people such as children, elderly, pregnant women, and individuals with weakened immunity. It's essential to know how flu leads to pneumonia, recognize early signs, and take preventive measures in order to keep the respiratory health safe.Influenza mainly infects the respiratory system, leading to an inflammatory reaction in the throat, nasal passages, and lungs. The body, in its course of operation, will most of the time end by killing the virus, hence recovering fully. However, in some cases, the flu can lead to pneumonia in two major ways:Viral Pneumonia: The influenza virus itself can directly infect the lungs, causing pneumonia. This is known as viral pneumonia and is more common in individuals with weaker immune systems.Secondary Bacterial Pneumonia: The flu can weaken the immune system, making it easier for bacteria to invade the lungs. This secondary bacterial pneumonia often leads to more severe symptoms and requires antibiotic treatment.
