Peter J. Irwin is an Infectious Disease Specialist based in Murdoch, WA. His practice address is 90 South Street, Murdoch, WA 6150, Australia. Peter focuses on infections that can be tricky, slow to settle, or just need a careful plan to get better.
Infectious diseases are not always straightforward. At times, people come in after tests don’t fully explain what’s going on, or when symptoms keep coming back. Peter works with patients who may have tick-borne type illnesses such as Lyme disease, babesiosis, ehrlichiosis, and relapsing fever. He also looks after cases where infections are related to the chest and throat area, including problems like mediastinitis, pneumomediastinum, and esophageal perforation.
He also sees people with more serious infections, including Pneumocystis jiroveci pneumonia. This can happen in situations where the immune system is under strain, so the right treatment and close follow-up matter. Peter takes a steady approach, focusing on what is most likely, what needs urgent attention, and what can be watched safely.
Over time, Peter has built experience across a wide range of infectious conditions. He pays attention to the details that can make a difference, like how fast symptoms started, what travel or tick exposure might be relevant, and what the lab results are really saying. In many cases, he helps connect the dots between symptoms, imaging, and test results so the treatment plan makes sense.
Peter’s education and ongoing learning are part of staying up to date in infectious disease care. Treatments and guidelines can change, especially for less common infections, so he keeps his knowledge current through professional development and by reviewing new information as it comes out.
When new options are available, Peter may discuss them as part of care, including how evidence from recent research fits the situation. Clinical trials can play a role for some conditions, and he stays aware of what’s happening in the broader medical world, even if a trial is not always the right fit.
If you’ve been dealing with a persistent infection, unusual symptoms, or ongoing concerns about test results, Peter aims to bring clarity. The goal is simple: get the infection under control, help you understand what’s happening, and make sure the next steps are clear and practical.
