Dengue Fever
Dengue is a viral illness caused by infection with one of four dengue viruses transmitted to humans by the bite of an infected Aedes aegypti mosquito. When a person recovers from dengue infection they develop a long-term immunity to that specific virus, but not the other three dengue viruses. If the person becomes infected again with a different dengue virus, there is an increased chance that they may develop a more severe form of the illness known as dengue hemorrhagic fever (DHF).
Public Health Travel Advisory
The Public Health Department has issued an updated Public Health Travel Advisory outlining current risks related to arboviral infections—such as Dengue, Chikungunya, Zika, and Oropouche—as well as bacterial infections like Leptospirosis for travellers between 12 December 2025 and 30 January 2026. The advisory provides key symptoms to monitor, affected destinations, and important prevention measures to help keep you and your family safe while travelling.
