Prof Christine Jenkins, chair of Lung Foundation Australia and a leading respiratory physician says Covid-19 pneumonia is different from the most common cases that people are admitted to hospitals for.
“Most types of pneumonia that we know of and that we admit people to hospital for are bacterial and they respond to an antibiotic.
Wilson says there is evidence that pneumonia caused by Covid-19 may be particularly severe. Wilson says cases of coronavirus pneumonia tend to affect all of the lungs, instead of just small parts.
He says: “Once we have an infection in the lung and, if it involves the air sacs, then the body’s response is first to try and destroy [the virus] and limit its replication.”
But Wilson says this “first responder mechanism” can be impaired in some groups, including people with underlying heart and lung conditions, diabetes and the elderly.
Jenkins says that, generally, people aged 65 and over are at risk of getting pneumonia, as well as people with medical conditions such as diabetes, cancer or a chronic disease affecting the lungs, heart, kidney or liver, smokers, Indigenous Australians, and infants aged 12 months and under.
“Age is the major predictor of risk of death from pneumonia. Pneumonia is always serious for an older person and in fact it used to be one of the main causes of death in the elderly. Now we have very good treatments for pneumonia.
“It’s important to remember that no matter how healthy and active you are, your risk for getting pneumonia increases with age. This is because our immune system naturally weakens with age, making it harder for our bodies to fight off infections and diseases.”
