  • Difficulty in breathing- Fast breathing or difficulty in breathing is always present in this disease. Whistling sound in breath is classical symptoms of chest congestion. It is caused by resonance from air due to less space in lungs.
  • Chest pain- Chest pain is always there in this condition. Pain would be worse with deep inhalation. This is known as pleuritic pain.

What cause pneumonia:

It can be caused by various factors, like bacteria, virus, fungus, parasites, and others. Most of the time infection is usually viral or bacterial. It usually starts with the infection of throat and nose. From there, pathogen goes down to lower respiratory tract. As the infection progress down to alveoli of lung, pathogens start multiplication and proliferation. In response to infection, body’s immune system increases blood flow towards the infection suite. This causes the lung to fill up with mucous, white blood cells and fluid. Congestion in lungs interferes with normal air space which causes difficulty in breathing.

Types of pneumonia:

 On the basis of causative factors, it is of two types.

1.      Viral pneumonia-

It is more common and less severe condition of this disease. Symptoms of this gradually start with mild fever and running nose. It worsens as days pass. Symptoms of this type can be similar to common cold and flu, or it can be said common cold or flu can turn into viral pneumonia in person with weak immunity. This type is the most common in child from age 1 to 5 year.

2.      Bacterial pneumonia-

In this type, all 5 lobes of lungs are inflamed due to bacterial or viral infection.

It is the infection of lungs due to bacteria. Usually all healthy persons have some or other types of bacteria in nose and throat. Due to strong immunity they remain there silently and do not produce any kind of symptoms.

As the immunity goes down these bacteria can enter in lower respiratory tract and cause inflammatory reactions, which lead to production of pathogen mix mucus. Thus, it reduces air space.

There are lots of bacteria which can cause bacterial pneumonia, but most common is Streptococcus. Symptoms of this type are little but serious compared to viral pneumonia and usually there is sudden onset of symptoms with high grade fever, severe cough and chest congestions.

How do you get pneumonia?

Pneumonia is a contagious disease. It spreads through touch or indirect contact like using same towel or sitting near to infected person. Nose discharge or sputum of person has thousands of spores of bacteria, fungus, and virus. These pathogens spread through sneeze.

How to diagnose pneumonia?

  • First diagnosis of pneumonia is done through clinical examination. Your physician would do auscultation through stethoscope. Whistling sound during every breath is suggestive for lung congestion.
  • Blood examination- There would be an increase in white blood cells and E.S.R level.
  • Sputum examination.
  • Chest X Ray.
