Causes of Pneumonia
The best causes of pneumonia causes which in the came way of the concretion.
- bacteria – the most common pneumonia causes in adults
- viruses – often responsible for pneumonia in children
- mycoplasma – organisms that have characteristics of bacteria and viruses that cause milder infections
- opportunistic organisms – a threat to people with vulnerable immune systems (e.g., Pneumocystis carinii pneumonia in people who have AIDS)
Most types of pneumonia are transmitted in the same way as influenza or the common cold – by people’s hands and by tiny droplets from their mouths and noses. In fact, the same viruses that cause colds and the flu can cause pneumonia. If they infect the throat, sinuses, and upper respiratory tract, they cause a cold. If they reach the lungs, they cause pneumonia.
Aspiration pneumonia is caused by accidentally inhaling food, vomit, or digestive acid into the lungs. The inhaled substance may become infected, or it may inflame the lungs and cause them to fill with liquid.
A person who has a higher risk of pneumonia:
- is under one year of age or over the age of 65
- is a smoker
- has a cold or flu
- has a weak immune system due to cancer therapy, HIV infection, or other disease
- is undergoing surgery
- has a problem with alcohol use
- has a chronic illness such as heart disease, lung disease, or diabetes
- has a chronic lung disease, such as asthma or chronic obstructive pulmonary disease
Symptoms and Complications
Pneumonia always causes a cough, which often produces sputum.Red-brown, green, or yellow sputum may be a sign of bacterial infection. Thin, whitish sputum is a possible indicator of mycoplasma or viral pneumonia.
In bacterial pneumonia, all or part of the lungs slowly fill with liquid in a process called consolidation. Some bacterial lung infections develop over just a few hours. There’s usually a high fever, sometimes going up to 40.9°C (105°F).
Other possible symptoms include:
- shortness of breath
- delirium (confusion)
- severe bad breath
- muscle pain
- chest pain, especially when breathing deeply
- blue lips and nail beds from lack of oxygen in the blood
Viral pneumonias don’t actually cause the lungs to fill with liquid; instead, they inflame the actual lung tissue itself. They are usually milder than bacterial infections. An exception is the influenza virus, which can be very serious.
