Pneumonia is swelling (inflammation) of the tissue in one or both lungs. According to the NHS, it's usually caused by a bacterial infection or a virus. Pneumonia can affect people of any age, but it's more common and can be more serious in certain groups of people, such as the very young or the elderly. People in these groups are more likely to need hospital treatment if they develop pneumonia. Other groups that have an increased risk of developing pneumonia include babies and very young children, people who smoke, people with other health conditions, such as asthma, cystic fibrosis, or a heart, kidney or liver condition, and people with a weakened immune system – for example, as a result of a recent illness, such as flu, having HIV or AIDS, having chemotherapy, or taking medicine after an organ transplant.
