Pneumonia is an infection that inflames the lungs' air sacs, causing them to fill up with fluid or pus. The symptoms of pneumonia include coughing, fever, chills, and trouble breathing. When diagnosing pneumonia, doctors will listen to the lungs with a stethoscope and check for abnormal sounds like crackling, rumbling, or wheezing. In viral pneumonia, doctors often hear breathing sounds that are not clear on either side of the chest. However, in bacterial pneumonia, lung sounds may seem normal on one side but absent on the other. While pneumonia can cause a variety of sounds in the lungs, it typically does not result in clear lung sounds.

Pneumonia is caused by bacterial or viral infections
Pneumonia is an infection that inflames the air sacs (alveoli) in one or both lungs. It is caused by bacteria, viruses, fungi, or chemical irritants. The air sacs may fill up with fluid or pus, leading to symptoms such as coughing, fever, chills, and difficulty breathing.
Bacterial pneumonia is the most common form and tends to be more severe than other types. It can develop after a viral infection or occur on its own. The most common type of bacterial pneumonia is pneumococcal pneumonia, caused by the Streptococcus pneumoniae germ. This type of pneumonia can be prevented with the pneumococcal vaccine. Bacterial pneumonia often affects just one part or lobe of a lung, and when this happens, the condition is called lobar pneumonia.
Viral pneumonia is caused by various viruses, including the flu (influenza), and is responsible for about one-third of all pneumonia cases. Viruses affect both sides of the lungs by producing a homogeneous inflammatory reaction that increases cellular debris and mucus. When a doctor listens to the lungs and finds breathing sounds are unclear on both sides, a viral cause is often suspected.
Mycoplasma pneumonia, also known as atypical pneumonia, is caused by the bacterium Mycoplasma pneumoniae. It generally causes a mild, widespread pneumonia that affects all age groups.
Identifying the cause of pneumonia is crucial for determining the proper treatment. Bacterial pneumonia is typically treated with antibiotics, while most viral pneumonias do not have a specific treatment and usually resolve on their own.

Symptoms include coughing, fever, chest pain, and trouble breathing
Pneumonia is an infection that inflames the air sacs in the lungs, causing them to fill up with fluid or pus. It can be caused by bacterial or viral pathogens. The symptoms of pneumonia can vary from mild to severe and may develop gradually or suddenly.
Coughing is a common symptom of pneumonia. The cough may produce greenish, yellow, or bloody mucus. Coughing is important as it helps clear the lungs of mucus. However, if the coughing is too severe, it may be necessary to take cough suppressants to help manage the symptoms.
Fever is another symptom of pneumonia. The fever may be high, up to 105° F or 40.55° C. Fever reducers such as ibuprofen or acetaminophen can help lower the body temperature.
Chest pain is also a symptom of pneumonia. The pain may feel like pressure, tightness, or squeezing in the middle of the chest. It may also radiate to the arms, back, neck, and jaw.
Pneumonia can cause difficulty breathing, as the inflammation in the lungs interferes with the exchange of oxygen and carbon dioxide. This may result in shortness of breath, rapid breathing, or even severe difficulty breathing, where the person struggles to speak without pausing, gasping, or choking. In very serious cases, breathing assistance through a ventilator may be required.

Diagnosis involves listening to the lungs and imaging tests
Pneumonia is an infection that causes inflammation in one or both lungs. It is usually caused by a bacterial infection, but it can also be caused by viruses, fungi, or other germs. The air sacs in the lungs become inflamed and fill up with fluid or pus, causing symptoms such as a cough, fever, chills, and trouble breathing.
Diagnosing pneumonia involves a physical examination, which includes listening to the lungs with a stethoscope. If you have pneumonia, your lungs may make crackling, bubbling, and rumbling sounds when you inhale. Doctors may also tap on your chest to listen for differences in sound between healthy lungs and lungs filled with fluid.
In addition to the physical examination, doctors may recommend imaging tests to confirm the diagnosis and learn more about the infection. These tests can include:
- Chest X-ray: This test is used to look for the location and extent of inflammation in the lungs.
- Chest CT: A CT scan provides a more detailed view of the lungs and can help identify abscesses or other complications.
- Chest Ultrasound: An ultrasound can also be used to evaluate the lungs and lung function and help determine the type of germ causing pneumonia.
- Needle Biopsy of the Lung: A biopsy involves removing small samples from the lungs for examination. This procedure can be done using X-ray, CT, ultrasound, or MRI guidance.
These imaging tests help doctors evaluate the lungs, assess lung function, and determine the specific cause of pneumonia.

Treatment options include antibiotics, fluids, and oxygen therapy
Pneumonia is an infection that causes inflammation in the air sacs of the lungs, which may fill up with fluid or pus. This condition can be caused by both bacterial and viral pathogens, with bacterial pneumonia being the most common form. The treatment options for pneumonia depend on the severity of the infection and the type of pathogen causing it.
Antibiotics
Bacterial pneumonia can be treated with antibiotics. These medications are typically administered intravenously through a drip if the patient is hospitalised. It is important to finish the entire course of antibiotics, even if one starts feeling better, unless instructed otherwise by a healthcare professional. If symptoms do not improve within 3 days of starting antibiotics, it is recommended to consult a doctor again. Antibiotics are not effective against viral pneumonia.
Fluids
Patients with pneumonia should drink plenty of fluids to help loosen secretions and bring up phlegm. In more severe cases requiring hospitalisation, fluids may be administered intravenously along with antibiotics.
Oxygen Therapy
Pneumonia can prevent the lungs from moving enough oxygen into the bloodstream, hence oxygen therapy may be required to increase the oxygen levels in the blood. In very serious cases, breathing assistance through a ventilator in an intensive care unit (ICU) may be necessary.
In addition to these treatments, patients are advised to get adequate rest and limit their contact with others to prevent the spread of infection. Over-the-counter medications like aspirin, ibuprofen, or acetaminophen can help control fever and body aches. Warm beverages, steamy baths, and humidifiers can also help open airways and ease breathing.

Prevention includes vaccinations, especially for high-risk individuals
Pneumonia is an infection that causes inflammation of the lung tissue, particularly the air sacs (alveoli), which fill up with fluid or pus. The symptoms of pneumonia include a cough, fever, chills, and trouble breathing.
Pneumonia is often caused by bacterial or viral pathogens, with bacterial pneumonia being the most common form. It is a serious illness that can even lead to death, especially in young children and older adults. Therefore, prevention is crucial, and this includes getting vaccinated, particularly for those at high risk of contracting the disease.
The pneumococcal vaccine is recommended for the prevention of pneumonia. This vaccine is especially important for high-risk individuals, including older adults over 50, adults aged 19-49 with certain chronic medical conditions like asthma, COPD, diabetes, and heart disease, and young children. According to the CDC, older adults are at the greatest risk of serious illness and death from pneumococcal infections. Additionally, people with underlying conditions or risk factors, such as autoimmune diseases, cancer, or chronic heart, lung, or kidney disease, are also at high risk.
Vaccines are an effective way to protect against pneumococcal infections, but they may not prevent all cases. It is important to consult a healthcare provider to determine the appropriate vaccinations for your specific situation. In addition to vaccinations, other preventive measures include frequent handwashing, avoiding close contact with sick individuals, improving indoor air quality, and disinfecting frequently touched surfaces. Quitting smoking is also crucial, as tobacco use damages the lungs' ability to fight off infection.
