PNEUMONIA is a swelling of the tissue in the lungs, and is usually caused by a bacterial infection.

These are the symptoms to watch out for, after Kim Kardashian and Kanye West’s son, Saint, was diagnosed with the condition.
The reality TV star praised the resiliency of Saint, and said that their “end of year was challenging”.
Pneumonia is a type of acute respiratory infection, that affects the lungs.
The lungs are made up of tiny sacs, known as alveoli, that fill with air when a healthy person breathes. But, pneumonia causes the sacs to become full of pus and fluid, according to the World Health Organization (WHO).
“Pneumonia is the single largest infectious cause of death in children worldwide,” said the WHO.
“Pneumonia killed 920,136 children under the age of five in 2015, accounting for 16 per cent of all deaths of children under five years old.”
The condition is usually caused by a bacterial infection, form the bacterial Streptococcus pneumoniae.
But, it can also be caught by a virus, a fungus, or even by simply breathing in a harmful substance, including smoke.
Symptoms of pneumonia can develop quickly, over a 24 to 48-hour period, according to the NHS.
Signs of the condition include difficulty breathing, a fever, chest pain, sweating, shivering and having a dry cough. The cough could be accompanied by a thick, yellow, green, brown or blood-stained mucus.
Coughing up blood, vomiting, wheezing, and headaches could also be a sign of pneumonia.
People showing typical signs of pneumonia should see a GP, while those experiencing severe symptoms - rapid breathing, chest pain or confusion - should seek urgent medical attention.
