With the wet season yet to start the north Queensland city of Townsville now has two separate dengue fever outbreaks. The Red Cross Blood Service said that to cope with dengue outbreak in Townsville extra donations were needed.

With 11 confirmed cases of the disease in the area the blood banks have stopped taking red cell and platelet donations in Townsville.

Mackay Donor Centre manager Karen Ashman said the restriction in Townsville was to have an impact on the entire state.

Queensland Health medical officer Dr Steven Donohue said that with two separate strains in the city, following a fresh occurrence last month, things needed great concern.

"It has actually restricted the collection of the red cells and the platelets and Townsville being our biggest regional centre outside Brisbane, it's having a serious impact on the blood collections across the entire state," Ashman said.

"We are asking the Mackay donors to lend a helping hand to our region and asking Queensland to come and give blood."

Queensland Health said in the suburbs of Garbutt, Heatley and Wulguru it had confirmed nine dengue type one cases and two type three cases and results on four other cases are to come on Friday.

Dr Donohue said, "We are unaware of the origin of this new dengue type three outbreak, but mosquito breeding sites have been recognized by mosquito control officers in Wulguru."

With dengue epidemic being the worst in last 50 years during the last wet season doctors have been put on alert.
