What is Pneumonia?

Introduction:

A bacterial, viral, or fungal infection can cause pneumonia, which involves lung fluid and inflammation. It makes breathing difficult and can result in fever, a cough with yellow, green, or bloody mucus, and other symptoms. The most typical causes of pneumonia include the flu, COVID-19, and pneumococcal illness. The etiology and severity of pneumonia affect the course of treatment.

 What is Pneumonia?

OVERVIEW

What is Pneumonia?

A lung infection known as pneumonia is brought on by bacteria, viruses, or fungi. Pneumonia can result in fluid or pus in your lungs as well as swelling of your lung tissue (inflammation). Viral pneumonia goes away on its own, whereas bacterial pneumonia becomes worse before getting better.

One or both lungs may be affected by pneumonia. Bilateral or double pneumonia is the medical term for pneumonia affecting both lungs.

What distinguishes bacteria from viral pneumonia?

All pneumonia is inflammation brought on by a lung infection.

But depending on whether a virus, bacteria, or fungus is to blame, you may experience various symptoms.

Viral pneumonia is less prevalent and usually not as serious as bacterial pneumonia. A hospital stay is more likely to be necessary. Antibiotics are used by providers to treat bacterial pneumonia. Flu-like symptoms are more common with viral pneumonia, which is more likely to go away on its own. Viral pneumonia doesn't need a specific course of therapy.

Which pneumonia subtypes are there?

We divide pneumonia into three categories: community-acquired, hospital-acquired, and ventilator-associated pneumonia.

Pathogens (viruses, bacteria, or fungi) that cause pneumonia are classified according to how it was obtained.

Community-acquired pneumonia (CAP):

Community-acquired pneumonia is the term used to describe pneumonia that is obtained outside of a medical setting. some causes are:

• Bacteria: The most frequent cause of CAP is an infection with the Streptococcus pneumoniae bacteria, often known as pneumococcal illness. Meningitis, sinus infections, and ear infections can all be brought on by pneumococcal illness. Atypical pneumonia, which has milder symptoms, is brought on by the bacteria Mycoplasma pneumoniae. Haemophilus influenza, Chlamydia pneumonia, and Legionella (which causes Legionnaires' disease) are more bacteria that cause CAP.
• Viruses: Pneumonia can be brought on by the same viruses that cause the common cold, the flu (influenza), COVID-19, and respiratory syncytial virus (RSV).
• Fungi (molds): Fungi are infrequent causes of pneumonia, including Cryptococcus, Pneumocystis jirovecii, and Coccidioides. The danger of contracting pneumonia from a fungus is greatest in people with weakened immune systems.
• Protozoa: Toxoplasma-like protozoa are a rare cause of pneumonia.

Hospital-Acquired Pneumonia (HAP):

While receiving treatment for another sickness or operation at a hospital or healthcare facility, you can get hospital-acquired pneumonia (HAP). Since HAP is brought on by bacteria that are resistant to antibiotics.

Such as methicillin-resistant Staphylococcus aureus, is more dangerous than community-acquired pneumonia (MRSA). So, HAP can make you sicker and be more challenging to treat.

Healthcare-associated pneumonia (HCAP):

HCAP can be acquired in outpatient, extended-stay clinics or when receiving long-term care in a facility (like a nursing home). It's brought on by germs resistant to antibiotics like hospital-acquired pneumonia.

Ventilator-associated pneumonia (VAP):

You run the risk of developing ventilator-associated pneumonia if you need a respirator or other breathing aid

while receiving medical treatment (often in the intensive care unit) (VAP). VAP is brought on by the same germs that cause hospital-acquired pneumonia as well as community-acquired pneumonia-causing bacteria.

Aspiration pneumonia:

When solid food, liquids, saliva, or vomit enters your lungs through your trachea (windpipe), it is known as aspiration. Your lungs could become infected if you are unable to cough these up.

How can I distinguish between pneumonia and the flu or a typical cold?

Only a doctor can diagnose you because it can be challenging to distinguish between the symptoms of a cold, the flu, and pneumonia. It's crucial to seek medical assistance if you experience any severe symptoms that can indicate pneumonia, including:

• Chest discomfort or congestion
• Trouble breathing
• 102 degrees Fahrenheit (38.88 degrees Celsius) or greater is considered a fever.
• Coughing up spit or mucus that is yellow, green, or red.

Who is most susceptible to pneumonia?

You have a higher chance of developing pneumonia if you:

• Are either under the age of two or older than 65.
• Are coping with lung or heart disease. Examples include pulmonary fibrosis, emphysema, cystic fibrosis, asthma, chronic obstructive pulmonary disease, and sarcoidosis.
• Have a neurological disorder that makes swallowing challenging. Your risk of developing aspiration pneumonia is increased by illnesses like dementia, Parkinson's disease, and stroke.
• Either a long-term care institution or a hospital.
• Smoke.
• Are Pregnant
• Have a compromised immune system. If you are through chemotherapy, receiving an organ transplant, have HIV/AIDS, or are on immune-suppressing medicines, you may have a compromised immune system.

What are the signs and symptoms of a mild case of pneumonia in adults?

Pneumonia is an infection of the lungs that can be caused by a variety of microorganisms, including bacteria, viruses, and fungi. The symptoms of pneumonia can vary depending on the cause and severity of the infection. In mild cases of pneumonia, the symptoms may include:

Cough - A dry or productive cough is a common symptom of pneumonia. The cough may produce sputum or phlegm.

• COVID-19 (SARS-COV-2).
• The flu (influenza virus).
• Human metapneumovirus (HMPV).
• Human parainfluenza virus (HPIV).
• Legionnaires’ disease.
• Mycoplasma pneumonia bacteria.
• Pneumococcal disease.
• Pneumocystis pneumonia.
• Respiratory syncytial virus (RSV).

Does pneumonia spread?

Although the bacteria and viruses that cause pneumonia are communicable, the disease itself is not. For example, the flu is contagious and can cause pneumonia, although the majority of people who contract the flu do not develop pneumonia.

Streptococcus pneumoniae, the bacteria that causes pneumonia, can be passed from person to person by coughing and sneezing, touching objects that have been contaminated, and so on.
