Year round, more common in winter months.
People of all ages. Most commonly and those at highest risk:
- Elderly
- Children
- People with weakened immune systems
- Smokers
- People with other chronic illnesses, especially lung problems
Pneumonia can be caused by a virus, bacteria, fungus, mycoplasmas or chemicals.
Often follows another illness, such as a cold or the flu
In most cases, people get pneumonia because they had an illness (such as the flu). When a person's body defenses are weakened by the flu, bacteria can invade the lungs and cause pneumonia. In some cases, bacteria can be passed from person to person causing pneumonia to be spread through the air.
The symptoms of pneumonia may differ depending on what is causing it, but some common symptoms may include:
- Painful cough
- Productive cough
- Fever
- Difficulty or painful breathing, especially when inhaling
Most cases of pneumonia require prescription medications for treatment so you must see a doctor to be diagnosed with and treated for pneumonia. Some people need extra oxygen when they have pneumonia and some cases may require hospitalization.
Pneumonia may be treated with antibiotics. Rest, proper diet and adequate fluids are also extremely important.
Pneumonia is diagnosed by x-ray and the x-ray is usually repeated a month or two after treatment to be sure the lungs are clear.
Some people are hospitalized with pneumonia, especially those patients at high risk. Pneumonia can be fatal. In fact, when combined with the flu, pneumonia is the 8th leading cause of death on the United States. The risk of contracting pneumonia and having serious complications can be greatly reduced by getting a pneumonia shot and a flu shot.
