About of Brett G. Mitchell

Brett G. Mitchell is an Infectious Disease Specialist based in Wahroonga, NSW. You’ll find the practice at 185 Fox Valley Road, Wahroonga, NSW 2076.


Infectious diseases can be tricky. They can range from common infections to more serious illnesses that need careful, ongoing treatment. Brett works with patients who may be dealing with things like urinary tract infections (including in children) and diarrhoea-related infections, as well as chest infections such as pneumonia.


At times, the focus is on infections that happen in hospital settings. This can include hospital-acquired pneumonia and issues linked with resistant germs like MRSA. He also looks after people who have conditions like sepsis, where fast assessment and the right treatment plan really matter.


There are also infections that can come with longer or more complicated courses. For example, Brett treats people with things like asymptomatic bacteriuria and pseudomembranous colitis, which may follow antibiotic use in some cases. In the right setting, he can also help with management of viral infections such as COVID-19.


Because infectious diseases don’t always sit neatly in one box, his approach tends to be practical and problem-focused. He looks at the likely cause, how severe things are, and what’s already been tried, then works out a sensible plan for the next steps. In many cases, that means aiming to control the infection and reduce the risk of it coming back or spreading.

Overall, the work is about helping people through infections safely, with care that fits the person, not just the diagnosis.
