3. Dengue fever with plasma leakage Patients with dengue fever with plasma leakage will have the same symptoms as in item 2. But when the fever starts, the symptoms will worsen with plasma leakage as mentioned above. If there is a leak, the blood pressure is lower. and have shock There is also a hemorrhagic condition. Sometimes there may be bleeding so much that a blood transfusion is required. Patients with shock will have cold hands and feet, rapid pulse, and restlessness. less urine output Plasma leakage typically lasts 24-48 hours, following which it enters a recovery phase. That is to say, the plasma leakage is reduced to a halt. The plasma that had leaked back into the blood vessels. The patient will start eating more. increased urination and a red, itchy rash on the limbs
