Dengue fever cases rise in north Qld

The number of cases of mosquito-borne dengue fever in Queensland's tropical north has risen to 50.

Queensland Health says 14 people have been infected in Cairns and 36 in Tully, Innisfail and El Arish this wet season.

The most recent cases were confirmed this week in Innisfail and the Cairns suburb of Edmonton.

Public Health Physician Dr Steven Donohue reminded those in the far north to remain vigilant and check their homes for any potential dengue mosquito breeding grounds.

This includes tipping out pots of water in yards and spraying indoors.

Teams from the health department's dengue unit will survey homes in Edmonton this week to try and stop the virus spreading further.

Dengue symptoms include headaches, muscle and joint pains, vomiting and diarrhoea.

During the 2013-14 wet season 136 people were infected with dengue in the Cairns region.
