This viral fever is transmitted by the Aedes aegypti mosquito from hosts including humans, horses, water birds, pigs and marsupials. Symptoms include sudden fever with headaches, muscle and joint pains, bleeding of gums or nose, a rash and in some cases vomiting and diarrhoea. There are four types of dengue fever and previously having one type does not give immunity against the others. The Aedes aegypti mosquito lives only in and around houses. Once an outbreak is discovered, if breeding sites near the initial infection are cleared transmission of the virus is halted.
Cairns, Innisfail and Townsville have experienced outbreaks this year, Queensland Health reports. There were 44 cases in Townsville last year.
