What is pneumonia?

It is a lung infection. Pneumonia happens when an infection causes the air sacs in your lungs to fill with liquid. That makes it hard for you to breathe insufficient oxygen to reach your bloodstream.

Anyone can get this infection especially the infants younger than 2 years and old people over 65 ages are higher at risk to get pneumonia.

In this article, we will discuss the following things regarding Pneumonia.

  1. What are the causes of Pneumonia?
  2. What are the symptoms of Pneumonia?
  3. How many types of Pneumonia are there?

What are the causes of pneumonia?

Causes of pneumonia are bacteria, viruses, or fungi.

Some common causes that include are:

  • Flu Virus
  • Cold viruses
  • RSV virus
  • Smoking and drinking too much can get you pneumonia
  • COVID’19 may get you pneumonia

What are the symptoms of pneumonia?

Symptoms of pneumonia vary from person to person depending on their age, what is causing them, their overall health, and the atmosphere. Symptoms are usually developed in several days.

Common symptoms include:

  • Pain in your chest and it gets worse when you breathe or cough
  • Cough that may cause mucus
  • Weakness and loss of appetite
  • Shortness of breath happens while doing normal activities or resting
  • Diarrhea, restlessness
  • Vomiting, and nausea
  • Getting chills, fever, headaches, and sweating

Newborn babies do not show any sign of pneumonia. They may vomit, have fever or/and cough, having difficulty in eating and breathing, and appear restless.

How many types of pneumonia are there?

There are four types of pneumonia

  • Walking pneumonia: It is called a mild case of pneumonia and it is not as serious as other serious types.

The causes include:

  • Inhaled food
  • Bacteria
  • Fungi
  • Viruses
  • Chemicals
  • Viral pneumonia: It can make you feel very sick as it is an infection in your lungs.
  • Bacterial pneumonia: This infection is caused to your lungs by certain bacteria. Streptococcus (pneumococcus) is the most common one. If you are young and healthy then this bacteria can live in your throat without causing any trouble and when your immune system becomes weak, this bacteria goes down to the lungs. When this happens, the air sacs in your lungs are affected and inflamed. The fluid is filled and that causes pneumonia.
  • Chemical pneumonia: Chemical pneumonia is caused by viruses or bacteria. It causes lung irritation. According to researchers, a very small percentage of pneumonia is caused by the chemical.

Pneumonia can also be classified according to where and how it was caused.

  • Hospital-acquired pneumonia (HAP): This type of pneumonia happens when you are admitted to a hospital. This type of pneumonia is more serious than other types as the bacteria causing this infection are resistant to antibiotics. You are more likely to get it if you are on a ventilator or when your immune system (your body’s defense against germs) is not strong enough.

Community-acquired pneumonia (CAP): A type of pneumonia that you get out the circle of a medical or institutional setting.
