Queensland health authorities have embarked on a massive mosquito controlling drive following the identification of 53 cases of dengue fever in Innisfail, a place south of Cairns in north Queensland.

Out of the 53 cases, 45 are Type 2 dengue and eight are type 4.

Authorities are visiting Innisfail homes to spray insecticides on mosquito breeding spots to control the dengue outbreak.

Public health medical officer Dr Steven Donohue, said,"In the short-term heavy rain can kill mosquitoes and give us a bit of a reprieve.But this outbreak is not over and we need the cooperation of the community to get rid of anything that's got water in it.When the rain settles down those dengue mosquitoes can breed up again and we could have another round of a very nasty outbreak. This dengue outbreak is now extending across most of the suburbs of Innisfail and it's a very difficult period now because with heavy rain, it means that these mosquitoes will be breeding well into what used to be the dry season."

Dear Yousaf,with Hypertension,another chronic disease,and age above 50,the afebrile period is significant,the patient should be advised about the warning signs for plasma leakaga,i.e, the reduced BP,or reduced pulse pressure[the difference between the upper-systolic and lower-diastolic one,e.g. if it comes down to 100/90.the increased capillary refilling time, the tender liver,and or hemmhorages,reduced urinary output,blood in vomiting,altered mentation,increasing respiratory disconfort. All these may indicate her transition towards shock,which is actually far more important than platelts,particularly in absence of internal or external bleeding . Observe your patient for all this,and then decide about discharge. Regards . P-dopp Peoples Doctors @ facebook.

The platelet count is not the only important determinant of bleeding.


Indications for blood/platelet transfusion as recommended in clinical practice guidelines are:

In cases with significant clinical bleeding, which require blood transfusion. Usually bleeding is > 10% of total blood volume (> 6-8 ml/kg of ideal body weight)
In adults with underlying hypertension or coronary heart diseases and platelet 1.3-1.5, which is the result of liver failure: Major contributing factor for massive bleeding.
There is no evidence to support the use of blood components such as platelet concentrates, fresh frozen plasma or cryoprecipitate. Its use could contribute to fluid overload.

Important instructions for treatment of DHF as per WHO/SEARO guidelines:

If the patient’s condition becomes worse despite giving 20ml/kg/hr crystalloid solution for one hour, replace crystalloid solution with colloid solution such as Dextran or Plasma. As soon as improvement occurs, replace with crystalloid.


In case of severe bleeding; give blood transfusion @ 20ml/kg for two hours. Then give crystalloid IV fluids @ 10 ml/kg/hr for a short time (30 - 60 minutes) and later reduce the speed.


If hematocrit falls, give blood transfusion 10 ml/kg and then give crystalloid IV fluids at the rate of 10 ml/kg/hr. The volume of blood administered should be just enough to raise the red blood cell concentration to normal.
