Pneumonia in Adults: Symptoms & Treatment

Q: Are pneumonia and influenza the same?

No, pneumonia and influenza are different conditions. Influenza (flu) is a viral respiratory infection that primarily affects the nose, throat and lungs. Pneumonia is an infection that causes inflammation and fluid accumulation in the air sacs of the lungs. Influenza can sometimes lead to pneumonia as a complication.

Q: Can I have pneumonia without a fever?

Yes, pneumonia can occur without a fever. Older adults, infants and people with weakened immune systems may not develop a typical fever response. Instead, they may experience symptoms such as persistent cough, breathlessness, fatigue, confusion or a drop in body temperature.

Q: How does pneumonia turn into sepsis?

Pneumonia can lead to sepsis when the infection triggers an extreme, uncontrolled response from the immune system, affecting the body's organs and tissues. The infection may spread into the bloodstream or trigger a widespread inflammatory response, potentially causing organ damage, low blood pressure and organ failure. Early diagnosis and treatment are essential to prevent serious complications.

Q: Can you get pneumonia more than once?

Yes. You can get pneumonia again, especially if you have a long-term lung or heart condition, a weak immune system, swallowing problems or you smoke. Staying up to date with vaccines and managing other health conditions lowers the risk.
