At a glance
- Dengue virus (four serotypes, DENV-1 to 4) is spread by day-biting Aedes aegypti and Aedes albopictus. Incubation is 3 to 14 days, usually 5 to 7.
- Almost all Australian cases are acquired overseas, mainly in Indonesia (Bali), Thailand, Vietnam, India and the Pacific. Local outbreaks happen in north Queensland and the Torres Strait, where Aedes aegypti lives. Wolbachia releases in Cairns and Townsville have largely stopped local spread.
- Notifiable. Fever more than 14 days after return makes dengue unlikely.
