Which of the following is a symptom of Severe Dengue Hemorrhagic Fever?

Cold and clammy extremities are a significant symptom of Severe Dengue Hemorrhagic Fever as they indicate a state of shock or severe illness. In cases of severe dengue, the body can enter a phase of plasma leakage which can lead to hypovolemic shock. This is characterized by decreased blood volume, making the extremities feel cold and clammy due to poor circulation and inadequate blood flow to the peripheries.

The other symptoms mentioned do not accurately represent the critical conditions associated with Severe Dengue Hemorrhagic Fever. Fever accompanied by cough may occur in many illnesses and does not specifically indicate severe dengue. A skin rash with no bleeding is a symptom that may present during earlier dengue phases but is not characteristic of the hemorrhagic form. Joint pain is a common complaint in dengue fever but is not exclusive to severe cases. Therefore, the correct identification of cold and clammy extremities as a symptom aligns with the severe manifestations of the disease related to circulatory compromise.
