In Cairns, two cases of the mosquito-borne disease chikungunya have been confirmed. Queensland Health is on 26 April 2013 issuing a warning for people to take precautions against the virus, which is similar to dengue fever in terms of symptoms and mode of transmission.
Tests the week of 22 April 2013 revealed that two people who recently returned from Papua New Guinea had contracted chikungunya virus infection, which includes symptoms such as fever, prolonged joint and muscle pain, headaches, rash and fatigue. Tropical Public Health Services staff have been spraying for mosquitoes in the neighborhoods where the two patients live.
The Cairns Post revealed that during the week of 15 April 2013, entomologists from Queensland Health and James Cook University were monitoring chikungunya following an outbreak in Papua New Guinea, where more than 3,000 people have been infected. The disease is carried by two mosquito species, Aedes albopictus and Aedes aegypti. Both also can transmit dengue fever virus, which has infected more than 110 people in Cairns, Innisfail, and Port Douglas since November 2012.
