To understand what causes pneumonia, we first need to know what it is and what its symptoms are. Having a good grasp of these aspects aids in the identification of proper treatments and preventive methods. What follows is the pneumonia definition and everything else that you need to know about it.
Pneumonia Definition: A List of Must-Know Topics About Pneumonia
1. Pneumonia Definition: What is Pneumonia?
Pneumonia is a disease wherein your lung tissues begin to inflame. The airway begins to fill with pus or unwanted cell material causing the air sacs to not work correctly. The tissue of the lungs is very delicate as it facilitates air to flow in and out. The tissue of the lungs can be easily damaged with slight mistreatment because they are delicate. If such a scenario takes place, pneumonia can occur.
Pneumonia can occur due to the invasion of 30 different organisms. These organisms include virus, bacteria, and fungi. Dust particles and intoxicating fine particles entering the air sacs of lungs may also be potential causes of pneumonia. But in medical science, in most cases, the reason for pneumonia is due to virus or bacteria. The most common type is the Streptococcus pneumoniae.
2. Types of Pneumonia Based on Source
As we go through the pneumonia definition, we can also tackle the different types of pneumonia. These can actually be interpreted in several ways due to factors like severity, effect and also the environment. In most cases, pneumonia is classified by doctors in the way that it is acquired by a host body. Based on such factor, the types of pneumonia is described below.
Community-Acquired Pneumonia (CAP) – This is a type of pneumonia which is acquired by the host body from the outside environment. In hospitals or general healthcare environments, the case of being affected by pneumonia is comparatively low. In that case, most of the pneumonia patients that come are affected by their community. CAP is a common disease in winter, and such cases are brought forward on a regular basis.
Hospital-Acquired Pneumonia (HAP) – This is the type of pneumonia that is acquired during hospitalization. The patient develops pneumonia while being admitted for other medical conditions. This type of pneumonia is less promising because the patient already has a preexisting condition.
3. Classifications of Pneumonia Based on Affectation
Bronchopneumonia is a case in which the patient’s air sacs have scattered inflammation. There are also patchy infiltrates. These are present throughout the lungs.
Lobar Pneumonia occurs when there is inflammation of a single lung. This inflammation in the single lobe creates effect throughout the whole airspace of that particular lobe.
Lipoid Pneumonia refers to the coagulation of fats within the air spaces of the lungs. The main reason of lipoid pneumonia is the aspiration of oil or obstruction of the airways.
4. Categories of Pneumonia Based on Causative Agent
Viral Pneumonia: If the person is infected by a virus, then it is called viral pneumonia.
Bacterial Pneumonia: If affected by bacteria, then the type of pneumonia is called bacterial pneumonia.
Fungal Pneumonia: If the inflammation is due to fungus, then it is called fungal pneumonia.
5. Other Known Types of Pneumonia
Aspiration Pneumonia – If you inhale drink or even food, saliva or vomit into your lungs, your swallowing reflex is impaired. This impaired reflex hampers your lungs can also cause pneumonia. This type of pneumonia is known as Aspiration Pneumonia. It is possible when a person is intoxicated or suffering from brain injury.
Walking Pneumonia – A person suffering from this type of pneumonia will have a sore throat, headache, tiredness, and fever with chills. Mild flu and severe coughing without mucus are other symptoms of Walking Pneumonia. This type is caused by mycoplasma which is an atypical bacterium. It is the smallest agent that can affect humans.
Ventilator-Associated Pneumonia – This is another type of pneumonia-related with Hospital-Acquired Pneumonia. It occurs when a person is hooked to a ventilator to support respiration. It is most common in intensive care units.

7. Defining a Contagious Disease
8. Contagious Disease Transmission
Physical contact – This is the first and the most dangerous mode of transmission of disease. A contagious disease is due to virus or bacteria. It must have the trait to be transmitted through physical contact, then and only then you will be affected.
Casual contact – This is another mode of transmission of contagious diseases. Casual contact is contact with the secretion of the person infected. You may also get infected if you touch objects touched by the person infected with the contagious disease.
Airborne – Contagious diseases may also be airborne. The virus or bacteria causing the contagious disease may affect you through the air that is transmitted into the body from the host.
