Sharon Y. Choo is a Pediatric Immunologist based in Parkville, VIC. Her practice is at 50 Flemington Road, Parkville, VIC 3052, Australia. She works with babies, children, and families when the immune system is not acting the way it should.
In many cases, this means looking after kids with immune problems that can make infections harder to fight. That can include conditions like Severe Combined Immunodeficiency (SCID) and other immune defects. It can also involve issues such as Hyper IgE Syndrome and related immune conditions, where children may get repeated infections or skin and lung problems.
Sharon also helps manage more complex immune and inflammation conditions. This includes hemophagocytic lymphohistiocytosis, histiocytosis, and related disorders. At times, these conditions can cause ongoing fevers, tiredness, and feeling very unwell, so early assessment and ongoing care matter.
Some children are referred after sudden or severe reactions, including anaphylaxis. Others may be dealing with long-term symptoms that link back to immune or genetic conditions, like X-Linked Lymphoproliferative Disease, IPEX Syndrome, or Isaacs’ Syndrome. There are also cases involving thymus-related immune absence, Omenn Syndrome, and Griscelli Syndrome.
There are times when her work overlaps with other serious conditions that need close coordination. For example, she also supports children with Pediatric Low-Grade Glioma (pLGG) and helps with immune-related care around treatment. She may also be involved in managing issues such as bone marrow transplant care in relevant cases.
Sharon looks after children affected by a wide range of infection and illness concerns. This can include Pneumocystis jiroveci pneumonia, pneumonia, mononucleosis, and viral infections like Rubella or other Togaviridae disease. Some families are also dealing with conditions linked to gut symptoms, such as diarrhoea, or with rare syndromes like fetal enterovirus syndrome and trichohepatoenteric syndrome.
Her clinic approach is steady and practical. She understands that these are scary problems for families, and plans care around what is going on for each child right now. The goal is clear: help the immune system where possible, manage symptoms, and make sure families have support while decisions are made.
