Pneumonia (new-moan-ee-yah) is a name used for an infection of the lungs. The name comes from the Greek word πνεύμων (pneumon) meaning “lung”.
The disease is usually caused by infection with viruses or bacteria, but not due to a single, specific virus or bacteria.
It kills millions of people a year, but is not always that serious. While it can affect anyone, it’s more likely to be seen in children under five years old, in the elderly and in people who are ill.
Symptoms include a high fever, chills, difficulty breathing, fatigue, chest pain and a cough, usually with a lot of phlegm that is either greenish or reddish.
In good news, healthy young people very seldom get pneumonia.
A person’s risk of getting pneumonia increase if that person smokes, has other diseases – like diabetes, smokes or has asthma or other lung diseases.
