Pneumonia occurs when a pathogen (most commonly Bacteria and Viruses, but very rarely Fungi) enters the lungs and causes the alveoli (air sacs that transfer gases to and from the blood when you breathe) to become inflamed and filled with mucus.
It can infect one or both lungs, so even if you don’t feel sick, one of your lungs may be filled with fluid. This can lead to people underestimating their illness and mistaking it for the flu or a cold. In some cases, the body will simply fight off the pathogens causing the problem before it becomes a problem, and it is dismissed as another seasonal illness.
Pneumonia can be fatal if left untreated, even if you’re otherwise perfectly healthy because it essentially chokes you from the inside out. Get doctor home visit services if you are not in a position to visit the hospital for easy diagnosis and treatment.
What are the Symptoms of Pneumonia?
- When you breathe or cough, you may experience chest pain.
- Older adults above the age of 65 may experience changes in mental awareness or confusion
- Coughing that may result in phlegm
- Fatigue
- Fever, sweating, and chills
- Body temperature that is lower than normal (in adults older than age 65 and people with weak immune systems)
- Vomiting, nausea, or diarrhoea
- Breathing difficulty
The symptoms may also vary as per the cause and also by the age of the person.
What Causes Pneumonia?
Pneumonia is classified based on the type of germs that cause it and where the infection occurred. Pneumonia can occur in four ways, which are as follows:
Community-acquired Pneumonia
The most common type of Pneumonia is community-acquired Pneumonia. It happens outside of hospitals or other medical facilities and could be caused by:
- Bacteria: Bacteria. Streptococcus Pneumoniae is the most common cause of bacterial Pneumonia. This type of Pneumonia can develop on its own or as a result of a cold or flu. It affects only one lobe of the lung and is known as lobar Pneumonia.
- Organisms that resemble bacteria: Pneumonia can also be caused by Mycoplasma pneumonia. It usually causes less severe symptoms than other types of Pneumonia. Walking Pneumonia is an informal term for this type of Pneumonia, which is usually not severe enough to necessitate bed rest.
- Fungi: Chronically ill patients or those with weakened immune systems are more likely to get this type of Pneumonia, as well as those who have inhaled large amounts of the organisms. It is caused by fungi that can be found in soil or bird droppings and vary depending on geographical location.
- Viruses: Viruses, including Covid-19, are the leading cause of Pneumonia in children under the age of five. Some viruses that cause colds and flu can also cause Pneumonia. The majority of the time, viral Pneumonia is mild. However, in some cases, it can be very serious. Coronavirus 2019 (COVID-19) has the potential to cause severe Pneumonia.
Hospital or Health Care-Acquired Pneumonia
People who spend a lot of time near or in hospitals or other healthcare facilities may be exposed to bacteria that are far more dangerous. The bacteria that cause Pneumonia acquired in a hospital may be resistant to antibiotics, and patients are already ill when they contract it. People who use breathing machines (ventilators), which are commonly used in intensive care units, are more likely to contract this type of Pneumonia.
Health-care-acquired Pneumonia is a bacterial infection that affects people who live in long-term care facilities or receive care in outpatient clinics, such as kidney dialysis centers. Health-care-acquired Pneumonia, like hospital-acquired Pneumonia, can be caused by bacteria that are resistant to antibiotics.
Aspiration pneumonia
Inhaling toxic materials can cause lung damage and chemical pneumonia. Because the process is primarily caused by inflammation rather than an infectious source, it is more accurately referred to as chemical pneumonitis.
Is Pneumonia Fatal?
Pneumonia can be fatal because the immune system is not fully developed in children, and it is frequently compromised in the elderly due to ageing or preexisting disease (such as diabetes or metabolic syndrome). Once Pneumonia has been established, bacteria or viruses can spread from lung tissue into the bloodstream and cause septicemia, which is a dangerous systemic spread of these pathogens. In some cases, a patient with bacterial septicemia will respond to two different types of intravenous antibiotics, but most often, the patient will die as soon as the pathogens have infected all of the vital organs.

Is Pneumonia Transmittable?
Pneumonia germs are highly contagious. This implies that they can spread from person to person. Pneumonia, both viral and bacterial, can infect others through the inhalation of airborne droplets from a cough or a sneeze. A pneumonia-causing microorganism or virus can also be transmitted by coming into contact with surfaces or objects contaminated with these microorganisms. There is a possibility of contracting fungal Pneumonia from the environment. It does not, however, spread from one person to the next.
