Pneumonia is an infection that inflames the air sacs in the lungs and causes a cough with phlegm or pus, fever, chills, and difficulty breathing. The disease can be mild or serious; even life-threatening.
What Are the Signs of Pneumonia as Opposed to a Cold or Flu?
Mild pneumonia may cause symptoms that are much like a cold or flu, but they last longer. Other more recognizable symptoms of pneumonia include:
- Chest pain with coughing or even pain with just breathing
- Confusion, especially in adults 65 or older
- A cough that produces phlegm
- Fever, sweats, and chills
- Lower than normal body temperature
- Persistent fever above 102 degrees
- Nausea, vomiting, or diarrhea
- Shortness of breath
If you’re experiencing any of these symptoms, you should see a doctor, especially if you’re over 65 or have an underlying health condition or weakened immune system.
What Causes Pneumonia?
You can develop pneumonia from a number of places and from various germs. Out in the community, you can be infected with bacteria such as Streptococcus pneumoniae, or a bacteria-like organism such as Mycoplasma pneumonia. Fungi from soil or bird droppings also can cause pneumonia to develop, especially in people with chronic health problems or weakened immune systems. Finally, viruses such as those that cause colds and flu can cause pneumonia as well.
Pneumonia contracted In hospitals or long-term health care facilities can be particularly dangerous, because the organism causing it may be resistant to antibiotics. The fact that you’re hospitalized or receiving long-term care can also raise the risk that your infection will be more serious since you’re already sick.
Pneumonia also can develop from aspiration, i.e. inhaling food, drink, vomit, or saliva into your lungs. This can happen when something disturbs your normal gag reflex, such as a brain injury, a swallowing problem, or the use of excessive amounts of alcohol or drugs.
Factors That Raise the Risk of Pneumonia
If you’re 65 or older, you’re at a higher risk of pneumonia. This is a simple fact, no matter if you’re fit and healthy.
If you also have COPD, asthma, or heart disease, your susceptibility to pneumonia is higher.
Smoking increases your risk of getting pneumonia because it damages your body’s natural defenses against bacteria and viruses.
If you have a weakened or suppressed immune system, you’re more susceptible too. This includes people who have HIV/AIDS or receive chemotherapy or long-term steroids or who’ve had an organ transplant.
Being hospitalized can raise your risk of contracting pneumonia, especially if you’re on a ventilator to help you breathe.

It’s Not Just Pneumonia Itself That’s Dangerous; It’s the Potential Complications
Even if you receive treatment for pneumonia, you’re at risk for developing these complications, especially if you’re in a high-risk group:
- Bacteria in the bloodstream. Your blood cells can spread the infection to other organs in your body.
- Breathing problems. If you have an underlying condition such as COPD, pneumonia can make your breathing even more difficult.
- Fluid build-up in or around the lungs. If this happens and the fluid becomes infected, you may have to have the fluid drained through a chest tube or even surgery.
- Pus could form in a cavity of the lung, creating an abscess. This might be successfully treated with antibiotics, but sometimes surgery or drainage is needed to remove the pus.
How to Prevent Pneumonia
The first line of defense begins with your lifestyle habits. Get enough sleep, eat nutritious foods, and exercise regularly. Being healthy and fit makes you less susceptible to disease. Here are three more important steps to take:
- Don’t smoke.
- Wash your hands often, or use a hand sanitizer.
- Get a pneumonia vaccine. Talk with your doctor about which vaccine is best for you.
