Dengue is estimated to affect up to 400 million people worldwide every year. Dengue is not endemic in Australia. However, it became nationally notifiable in 1991. Until 2009, there were typically less than 100 notifications a year, many of which were imported from Papua New Guinea. Since then, however, there has been an upward trend to as many as 1200 imported cases a year, mainly from travellers who visit Indonesia. North Queensland experiences outbreaks of dengue every year from returning travellers. The largest recent outbreak in Australia was in 2016 where there were over 2000 confirmed cases, including many from Western Australia, Victoria and New South Wales.
