David A. Jans is an Infectious Disease Specialist based in Melbourne, working from 19 Innovation Walk, Melbourne, VIC 3800, Australia.
David looks after people with a wide range of infections. That can include serious viral illnesses and sudden outbreaks, where testing and fast treatment really matter. In many cases, patients come in with fever, feeling very unwell, or symptoms that don’t settle the way they should.
Care often covers illnesses like dengue fever, Zika, West Nile virus, and rabies. It can also include viral haemorrhagic fever and other rare or high-risk infections. Over time, this kind of work means staying on top of how diseases spread, what symptoms to watch for, and what to do next while results are still coming in.
Respiratory infections are another big part of the mix. This includes infections such as RSV, parainfluenza, and pneumonia. At times, patients may also be dealing with more severe breathing problems, including illnesses linked with SARS and other big outbreaks.
David also supports people with infections that affect the brain or nervous system, such as encephalitis and infections related to cytomegalovirus. There are also conditions seen in pregnancy, like fetal parvovirus syndrome and parvovirus antenatal infection, where careful advice is important.
Not every referral is just about a single virus. David also works with cases involving HIV/AIDS, toxoplasmosis, and other complex long-term health problems. The practice also takes calls involving certain cancers such as triple-negative breast cancer and support for infertility. If someone is dealing with something complicated, David helps sort through the options and focuses on what’s most useful for the next step.
