How could pneumonia impact you?


Pneumonia can affect people for a long time, with fatigue lasting up to three months and it taking up to six months to get back to normal.3

​​​​​​​
Mild cases of pneumonia can leave you with a cough that persists for up to six weeks after treatment.3 Often, people may feel tired and are unable to return to their normal daily routine for quite some time.3

Severe cases of pneumonia could have significant longer-term effects on your life where you may have difficulty or require help to carry out simple daily activities.4

​​​​​​​
Most people will recover fully after treatment but pneumonia can lead to serious complications in people who are very young, very old or have a long-term medical condition.1​​​​​
