Jessica J. Harrison is an Infectious Disease Specialist based in St Lucia, QLD 4072. She looks after people with serious infections, especially when the illness is caused by viruses that can spread through mosquitoes or from travel.
In day-to-day care, Jessica focuses on working out what is making someone unwell and helping them get the right treatment quickly. That can be important when symptoms are severe, when someone has a high fever that won’t settle, or when an infection affects the brain and nerves. At times, it also involves supporting people who are dealing with complications like dehydration, low blood pressure, or sepsis.
Her clinical work covers infections such as Japanese encephalitis, yellow fever, dengue, Zika, West Nile virus, and other arboviruses. She also sees cases linked to viral haemorrhagic fevers and other tough, high-risk viral illnesses. The goal is to be thorough without making things complicated—collecting the right history, running the needed tests, and then guiding care step by step.
Over time, Jessica has built experience caring for patients with complex infectious conditions. Many cases come from people returning from travel or from times when there are outbreaks in different parts of the world. In many cases, she helps coordinate with local teams so patients can be managed safely and monitored closely when things change.
Jessica’s education and clinical training have a strong focus on infectious diseases and how they behave in the body. She understands that infections can move fast, and that good communication matters just as much as the tests. She tends to keep explanations clear and practical, especially for families who are trying to understand what is happening and what happens next.
When it is relevant, she also considers the bigger picture around infectious diseases, including prevention and early recognition. Her approach is grounded and calm, particularly when a diagnosis is still being worked out. This is a specialist service for people who need careful assessment, careful treatment planning, and strong follow-up.
Jessica works in St Lucia and serves patients across Queensland who need expert help with infections like those listed above, including encephalitis, sepsis, and other serious viral illnesses.
